RAID 0 OR NOT?
I am planning on getting a new computer and will be using Sound Forge 8
on it. Would getting RAID 0 hard drives be worth the extra $140 or so (for a Dell 9100, for example)? I know that RAID 0 improves performance on some applications, but not all. What about SF 8 and other audio editing software? Anyone have any experience here? Thanks. |

Both striping and mirroring enhance the performance of hard drives. When you stripe, you get a doubled probability that a single device failure will take you down, but you also get twice the space. When you mirror, you get zero probability that a single device failure will take you down, but you don't get the doubled space. Hard drives are among the least reliable of PC components. Therfore, mirroring is a pretty good idea, especially given the low price of disk space. |

Thank you for your response.
Actually, I'm more interested in speed rather than security as these files are pretty much backed up already in their original format on CD's and DAT's and could be easitly redone if there were a HD failure. I was wondering if there is a real difference in performance between the serial ATA hard drives that come standard with computers these days and the optional RAID O configuration. Since these audio programs are hard drive based, I would think that faster HD performance would be a definate plus. Or, the difference might be so minimal that it's not worth it. (Incidently, I asked Sony Pictures (who market Sound Forge) this question and they couldn't tell me. I don't think they know much about what they're selling). |

Are you trying to solve (or prevent) some particular issue? Like are you simultaneously recording/playing so many tracks that you fear that conventional disc solutions will be a bottle- neck? Beware of RAID just because it sounds cool. Merely running Sound Forge 8 isn't necessarily a valid reason for considering RAID. More information about what you want to do would be in order (particularly: how many channels you are recording/mixing, and whether you are also doing video, the size of all the drives on the PC, etc. etc.) |

(Incidently, I asked Sony Pictures (who market Sound Forge) this question and they couldn't tell me. I don't think they know much about what they're selling). I run a stripped set ( 3 10k scsi drives with software raid 0 ) but the difference between the stripped set and a single 10k drive isn't huge. When I tested it a while back I think I could simultaneously record 52 tracks at 24/96 on the single drive and 58 tracks on the stripped set. I think a hard ware raid setup would be even a little more efficient but I don't know for sure. With my current setup and foreseeable project needs I don't think I'll be recording more than 16 tracks at a time so the increased risk of running a stripped set probably isn't worth it. What is really had on a system is to play back a lot of tracks while recording a bunch at the same time. If you go for a stripped set I'd recommend two or more fast small drives and use that as your 'working' drive and then move project off to larger / cheaper drives when done. -- John L Rice |

Also, I've read that write performance for a mirrored set can be a little less than for a single non-raid drive. John L Rice |

I want faster! Editing and processing audio.
SF 8 is a 2 channel program and I won't be doing video. SCSI is expensive, while RAID 0 is not--but is it faster than plain old SATA? Thanks, jixelub |

Speaking as a computer tech : One drawback of the Dell machines is that they usually don't have the drive expandability to do any more than two hard drives. Out of necessity, I'm using a desktop box as a server, and I had to purchase a drive cage to mount a hard drive in an 5 1/4" bay, where you'd usually mount a CD-ROM. So, if you're looking to use 3 hard drives, one for the OS, and two in a RAID for data, you'll need to get a drive mounting kit from NewEgg or similar supplier to put a 3 1/2" drive in a 5 1/4" space. jtougas listen- there's a hell of a good universe next door let's go e.e. cummings |

Let's be careful here, and remember that RAID is just a way to hook up multiple drives. It doesn't matter if it's SCSI, EIDE, or SATA, they can be hooked up in RAID. You just can't mix types, and it's best not to mix sizes (except in a very special circumstance). In other words, RAIDs work best when you've got multiple drives of the same type and same size (and ideally speaking, the same model, though that's hardly necessary). But yes, SCSI drives are more expensive than EIDE or SATA. The performance from SATA is better than EIDE, but the durability of SCSI drives is generally better than SATA and EIDE. I would highly suggest using a good RAID card instead of doing a software RAID under Windows (assuming you're using Windows). Downside, good RAID cards aren't cheap, but the performace returns are worth it. jtougas listen- there's a hell of a good universe next door let's go e.e. cummings |

This link has some basic info on RAID types: http://www.ebabble.net/html/types.html Raid 0 stripes data across 2 drives, so you get faster IO, however you may find RAID 1 is more useful as it mirrors the data. It is only slightly slower than RAID 0 and gives you data protection too. In IT circles, it is common to use RAID 1 (mirroring) for system drives and RAID 5 for data drives. RAID 5 stripes the data across multiple drives (minimum 3), so it gives greater protection against drive failures. There is no real performance benefit though (no cost either), so this might not transfer to a DAW quite so well. |

When you stripe, you get a doubled probability that a single device failure will take you down, but you also get twice the space. That can be achieved more cheaply with a larger hard drive. The real advantage of stripe is that it writes sequentially across the drive(s), thus substantially increasing write-speed. This is not as big an issue with modern hard drives as it was for older drives. The disadvantage of stripe 1 mentioned by Arnie above (disk failure) doesn't count once you get to Raids 3, 4, or 5 which use additional disks but carry the capacity to rebuild on the fly without interruption. When you mirror, you get zero probability that a single device failure will take you down, but you don't get the doubled space. Right, so this is the preferable use for a DAW. And if you are using separate disk drives for program content and audio data both should be mirrored. Hard drives are among the least reliable of PC components. Therfore, mirroring is a pretty good idea, especially given the low price of disk space. |

The biggest is speed, since the data is written and read sequentially across the disks. The second is that they allow hot-swapping (assuming the hardware can handle this) and rebuilding on the fly if there is a failure. So you get protection during a recording session as well as speed. However, as I noted in another post...speed is generally less of an issue today than it was in the past. 7200 rpm drives are fast, and 10,000 rpm drives are super-fast. The speed advantage of raid was a much greater advantage when drives were slower. |

You've gotten some really good advice so far in this thread, and some not so good too, I'd like to reinforce and/or clarify a few things: While RAID 0 will typically improve read/write performance, it does nothing for fault tolerance. (But you say speed is you concern, not fault tolerance). I agree with the poster that says that the RAID 0 Striped set alone isn't going to make a *huge* difference. Noticeable, but not huge. I also very much agree with the poster that suggests using a separate hardware controller card if you want to take maximum advantage of increased speed; because the bottleneck of using software control, will probably negate much of the advantage of using multiple drives. Mirroring actually slows write times, but may increase seek/read times, and is mostly useful for fault tolerance not speed. I also agree with the principal of mirroring system drives with fault tolerant striped sets for DATA, at least in a heavy use general purpose server, but that brings the minimum number of drives up to 5! Another post I agree with; Using RAID just because it seems like a "pro" thing to do, isn't necessarily a good reason. Here is my recommendation that can give you a good advantage in drive I/O speed, without the hassle of using RAID at all: Use three drives. Two of them don't even have to be that large, but they should be fast 7200rpm and ATA-100100 or such. Your third (data) drive should be large and fast. The OS and your MIDI/Audio Sequencer software go on drive #0. You don't allow widows to manage the virtual memory. Manually set the swap file (virtual memory) at a very large size (2-3 times the amount of actual RAM installed in the computer, and put it on drive #1. Set the default for 'track temp' files of your MIDI/Audio sequencing software to drive #2. Here are the advantages of this setup: The OS and Applications being on the same drive reduces seek times between them due to sharing the onboard cache of drive #0 (needless to say, the bigger the cache, the better) The constant hits on the virtual memory (and there are a lot in audio recording) don't bog down the OS and/or DATA drives. All drives are dedicated to performing operations most likely to happen within their own little 'domain' and this reduces bottlenecking in the disk control system! Note: This system may be improved with the addition of a fourth drive to separate the OS and Applications, and also by the use of a controller card that avoids the connection of multiple drives on the same buss in master/slave dependency. (And of course *never* put a HDD that you want to perform well, on the same buss with any kind of CD/R/RW.) Big drawback: *no* fault tolerance whatsoever. Now, I haven't tested my theoretical system against a RAID 0 striped set for speed comparison, but I wouldn't be surprised if it were at least as fast, if not faster. I would also expect it to be very reliable. I have my system set up in a variation of this right now, using only two drives and multiple partitions, and it has been working very well for me.

Hi,
The bottom line is that for your application, (SF8 recording two tracks) any RAID system is completely unnecessary, and an unneeded expense. Any decent existing drive will record and play back two tracks with ease. Is it really worth the money for RAID to get a system that is 60X as fast as needed instead of 50X? I think you'll agree that there's no reason to go there. On the other hand, RAID is fun to play with, and if the geek factor is important to you, then consider it. It's an interesting thing to learn about first-hand. But from a practical point of view it's overkill at a very high level, for your application.

I was wondering if there is a real difference in performance between the serial ATA hard drives that come standard with computers these days and the optional RAID O configuration. Yes, it ranges from an approximate 50% average advantage for mirroring to closer a doubling of average performance for striping. I say average, because in certain short term sitautions the advantages may be less. Since these audio programs are hard drive based, I would think that faster HD performance would be a definate plus. It is often a very obvious advantage. A PC with either striping or mirroring just feels loser and quicker. |

You will not have a problem with audio based applications with even a single
drive with the application you specified. Audio doesn't eat up that much bandwidth in a stereo environment, so don't worry about it. If you want a more specific answer with graphs and curves and datapoints, then both Arny and I can provide such, but it's moot. Stereo is 172,000 bits per second, or thereabouts. Most drives can easily handle at least 40 MB/s, so you can see the negation of your concerns. -- Roger W. Norman SirMusic Studio http://blogs.salon.com/0004478/ "jixelub" wrote in message ups.com...

The appearance of faster is somewhat disinformation. SCSI may be more
expensive, but IMHE the ability of SCSI to do the job reliably across the disk surface far surpasses the ability of ATA. In terms of SATA, it depends on more than just the SATA interface. ATA works of the PCI bus and does a good job in that method, but SATA seems to work better as a hang off of the Southbridge rather than the PCI bus, so a couple of 120 gig SATA drives I have, which run off the PCI bus don't do any better than ATA and they do so more sporadic than ATA. Not that either can't handle as much as the 24 simultaneous tracks of recording that I throw at it, but there it is. Once you talk about a stereo editing program, who cares? Not to be snide, but even a basic 7200 drive will handle the application. -- Roger W. Norman SirMusic Studio http://blogs.salon.com/0004478/ "jixelub" wrote in message oups.com... I want faster!

Maybe a technicality in perception but I'd say that with stripping you get

Also, I've read that write performance for a mirrored set can be a little less than for a single non-raid drive. Maybe I'm wrong, but I may have written that in terms of today's drives. And perhaps it's the drivers, or the bus they run off of. When my A64 runs it's SATA drives/drivers off the PCI bus, obviously it cannot achieve the throughput specs since they are 150 MB/s for SATA and 130 MB/s for PCI. Plus there's a translation invovled. But a SATA striped set running directly through a Southbridge chip should be more solid and quicker than off the PCI bus. In my A64 raids, I have both IDE on a Gigabyte chipset and a SATA raid ITE chipset, both hanging off the PCI bus. The IDE is just only a slightly bit better, not because it's faster at maximum throughput, but because the SATA drive's transfer range looks like the Cascades in Washington State. I'd rather have slower but more reliable transport of data than quicker and eradict transfer, so to me the SATA drives weren't worth the expenditure. To someone with an A64 that has SATA hanging off the Southbridge, I'd bet, but can't confirm, that SATA would kick butt. Unfortunately today I'd have to buy a new mobo, X2 processor, and different memory (DDR2) in order to gain any advantages over my current system, and it works just fine for 24 tracks of simultaneous recording. However, my Athlon XP1600+ did so too. Oops, and with striping you get somewhat more consistent data throughput because one drive works from the outside and the other works from the inside, thus averaging the data transfer over both drives. Then again, one only has to remember that RAID means Redundant Array of Inexpensive Disks to understand that we can't be talking about optimized situations with RAID anyway. That RAID works better is just enough. One cannot expect it to be a significant improvement, but in some cases any improvement is a significant improvement. -- Roger W.

However, just the same, anytime you have two or more fast hard drives available, moving the Windows Swap File (virtual memory) off of the (OS) drive will make a worthwhile difference in both speed and smoother disk access / data flow. Indeed, the benefit might be as much as gained by a striped set w/o fault tolerance (RAID 0). John King |

raid will improve the performance off all applications. what it does
is split the audio across two drives. the most important aspect is your average seek times get cut in half. it really helps when you are trying to do multitrack work, especially at high sample rates. remember, it used to cost $30,000 for a top-grade 24 track analog tape deck, and a reel of 2 inch tape would set you back $200 or more. computers are so dirt cheap comparitively that it's crazy not to spend for something like this. you can always throw backup drives out on the external firewire chain. that being said, if all you are doing is strictly 2-track editing, raid 0 is completely unnecessary. |

Thank you all for your responses to my question. Twice as fast saving
files would definately be worth the $100 or so more for RAID. I just finished changing the volume on a 50 minute wav file (525,740KB) and it took 4 minutes, 20 secs. Adding reverb could take over 6 minutes. This is on an OLD computer with Ultra ATA 33/7200rpm HD. Of course a new SATA would be better, but would RAID be even better than that? It would seem that most people are using their computers for recording multitrack recording and you would need mirroring for that, but for processing, moving and saving those huge files, don't you need speed? jixelub |

RAID 0 OR NOT?

Hard drive speed/capacity mainly affects the number of tracks you can record and play back at the same time. If you are only doing 2 track work, spending money on a faster hard drive setup would be a waste in my opinion. My old Amiga 3000 with 25MHz 68030 CPU and 12 Meg RAM and 4 gig SCSI-2 drive handled stereo recording/playback beautifully. -- John L Rice www.DeliriumFix.com |

Probably the best buy is getting a couple of Gig of RAM so you don't have to use the disk so much. -- Dirk The Consensus:- The political party for the new millenium http://www.theconsensus.org |

RAID 0 OR NOT? or iSCSI
Many of you miss the point. Sound Forge, like most audio editing
software, is hard drive based. That means that it does all of its work on the hard drive, not with the RAM. This is necessary because the size of the files are potentially so big that it is impractical to do it with RAM. This is also the reason why it is a good idea to defrag the hard drive frequently to improve performance, as these programs suggest. I am not talking about performance merely for playback or recording. That is easy. I am talking about editing, processing and mastering stereo tracks that are sometimes quite long. They have to be written and rewritten every time you do something. A fast hard drive is the best way to improve the speed of doing these things. Thus, my question was, is RAID worth the extra money to increase the speed of using Sound Forge 8? jixelub |

I get some 80-90 tracs out of a sata drive, well beoynd my needs most
of the time. (With Nuendo and pretty average computer) Matti |

I may no be the best person to explain how it works, but every function you do is not limited to the hard drive speed. I open a 3 hour long file and delete 2 hours of it in Audition or Sound Forge 8 and it is done instantly. The whole file doesn't need to be re-written, only pointers. Most of the work I do is cutting and pasting which goes quickly. Say you add reverb or eq or some other DSP to a long file. Yes, this does have to be written to the hard drive, but is that the limiting factor or is it the speed of your CPU? I'm sure both are factors. I can't quantitatively which is the bottleneck for any given dsp, but others here possibly can. Julian |

No, not every function, but OTOH its hard to go through a project where hard drive speed isn't an issue. I open a 3 hour long file and delete 2 hours of it in Audition or Sound Forge 8 and it is done instantly. Since you said Audition and I use it, I'll speak in that context. If you delete part of a file in Audition, you'll still be bound by disk drive speed if your deletions are much more than simple, or if you want to render the file in MT view. The whole file doesn't need to be re-written, only pointers. IME editing in EV mode in Audition almost always involves a lot of disk activity. Most of the work I do is cutting and pasting which goes quickly. Say you add reverb or eq or some other DSP to a long file. Yes, this does have to be written to the hard drive, but is that the limiting factor or is it the speed of your CPU? Depends on the speed of the drives and the CPU. I edit on an Athlon 64 3000, and that tends to lead to sitautions that are drive-speed bound, even with lots of large 7200 rpm SATA drives. I'm sure both are factors. I can't quantitatively which is the bottleneck for any given dsp, but others here possibly can. I work on different machines, and that helps one get an impression about what matters, hardware config wise. Over time improvements in hard drive speed has generally lagged improvements in CPU speed. |

In that case, if you use 10 minutes out of a 3 hour file, you are still storing 3 hours worth of file space. Many users would not find that particularly admirable or beneficial. |

When you cut the 2 hours out of the 3 hour file as you describe, you
actually didn't change the file on the hard drive at all (that's why it happens almost instantaneously) To make the change really happen, you have to save the new 1 hour file. Surely there is someone out there using RAID O configured hard drives. Are they faster or not? |

I know. That's what I meant by it "only changes the pointers". I'm saying I can take a long live 2 track recording cut it down to a single 80 minute CD, do short fade ins and outs between tracks add splits etc. without having to wait on the hard drive hardly at all until I go to save the finished recording or if I need to do some dsp. I don't mind waiting 5 minutes at that point. I'm usually ready to go to the fridge for a cold beverage about then. But I would also like to hear some hard facts about how much faster RAID 0 is. |

I pretty well scrapped striping for any purpose when 7200 rpm drives got cheap and common. I agree with Arny on this. Raid 0 is faster, but this was more important when disks were slower. If speed is your primarily concern, consider moving to a 10,000 rpm Raptor drive and mirroring it for safety and then archiving it offline onto a more conventional 7200 disk or transferring it via network to a storage server. 74GB is still a lot of space for individual project files. |

news 74GB is still a lot of space for individual project files. In my case, just 12. My current editing machine has a max capacity of just under half a terrabyte on 4 drives. The field recorder has about half that. |
