sample rate question with 5400rpm hard drives
Hello,
Most notebook computers come with 5400rpm drives. If you wanted to record a single stereo track at 24/96 or maybe even 24/192, can this be done ok on such a slow drive? I know that a 5400rpm drive would be terrible for trying to mix tracks. But I was thinking more in terms if you wanted to create a single stereo track high-resolution sound of a car door closing for a sound effects library. Maybe you could record with a huge buffer or something like that and get the single stereo track o.k. at high resolution. Not really worried about latency/headphone monitoring and things like that. Just wondering if it's possible/feasible, for short on-scene sounds to do o.k. with a standard 5400rpm drive. |

sample rate question with 5400rpm hard drives
The rotational rate of the drive has nothing to do with the disk's areal
density. In and of itself, it tells us nothing about how rapidly data can be laid down. And as far as I know, the software and/or the drive would be buffered. |

What makes you think it is a slow drive? - you got the parameter wrong, what matters is the "number of magnetic domains" pr. revolution. I know that a 5400rpm drive would be terrible for trying to mix tracks. From what source? - in my "pile of drives" there is 3 120 gigabyte WD drives that I rushed to a good number of years ago because they were with "the old mechanism" and "new platters" and consequntly offered a higher data rate than competing 7200 rpm drives. But I was thinking more in terms if you wanted to create a single stereo track high-resolution sound of a car door closing for a sound effects library. Maybe you could record with a huge buffer or something like that and get the single stereo track o.k. at high resolution. You can with some software record to ram and dump the file to disk afterwards. Not really worried about latency/headphone monitoring and things like that. Just wondering if it's possible/feasible, for short on-scene sounds to do o.k. with a standard 5400rpm drive. You got the notebook problem plain wrong, the issue that still may or may not be relevant is the graphics card architecture, ie. whether the graphics card has its down physical ram or not, but with the general increase in hardware capability that may now has become a non-issue.

Even though many people like the Zoom H2, I´ve always found it to have the typical "artificial" sound, that I´ve disliked in all Zoom devices since the early 90s. As there are so many alternatives from other makers meanwhile, I´d rather check those out, before buying a Zoom one, You can do multiple VIDEO streams to modern drives, so audio is certainly no problem. Unless you employ the hd drive with something else, that really causes a lot of read/write action at the same time. ...and I assume, noboby would defrag a drive, while recording to it. ;-) |

Probably because it's a number that they can see and, at least on a physical level, relate to. It's true that higher platter speed can increase the total throughput (though not indefinitely, since you run into a speed limit of the I/O path) and you know how people are since we've had the Internet. Because there are drives with higher platter RPM, those with lower speed must be inferior. They (the people, or, I believe, the Internet) weren't around when there were 2000 RPM drives. HD recording was done professionally on 5400 rpm drives before there were 7200s.... IF they really are *so* concerned about it, why don´t they just get a SSD drive, which is faster *and* shock-resistant, as a nice side-effect. I was looking into solid state drives a year or so ago and found that those that weren't much more expensive per byte than mechanical drives had substantially lower throughput. Now you can get SSDs with faster throughput than a mechanical drive for only a little more cost, but the cheap SSDs are still slower. In my case, however, nearly everything but my newest computer uses parallel IDE drives and all the SSDs are SATA. I have an adapter that allows me to connect a SATA drive to a parallel port, but I haven't done any testing to see if it ends up slower than a parallel drive connected to the same port, for the same application. How good can a $10 adapter be? g -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |

Hello, Most notebook computers come with 5400rpm drives. But if it matters, upgrading them to modern high density 7200 rpm drives is not rocket science. If your laptop's BIOS can handle it: http://www.tigerdirect.com/applicati...326&CatId=1277 If you wanted to record a single stereo track at 24/96 or maybe even 24/192, can this be done ok on such a slow drive? I know that a 5400rpm drive would be terrible for trying to mix tracks. You'd be wrong. You're looking at the wrong number. For audio, the most relevant parameter is DTR or Data Transfer Rate. DTR is the product of rotational speed *and* the amount of data on a track. The density of data on each track of a modern hard drive has gone up immensely, due to changes in technology. A modern 3600 rpm drive has a DTR that is equal or greater than that of a 7200 rpm drive from back in the day when 7200 rpm drives were strongly recommended for audio. |

OTOH, I rarely go beyond 16tr. In that sense, 7200 rpm seams to be nothing but sails pitch, both in computer sails marketing, aswell as in studio time. Just like ther's almost no difference in sound with all the various equipment, given they are built properly and not pushed too hard, thers no difference in using 5400 or 7200 before you hit really high track count. Since there has to be something to distinguish real studio from "home" one, 7200 was one such thing, especially in days when 7200 were more expensive. Also, there has to be something to make you change perfectly good HD for a new one. With cheaper HDs labeled 7200 studios have to go elswhere to drive custommers in. Again.

In that sense, 7200 rpm seams to be nothing but sails pitch, both in computer sails marketing, aswell as in studio time. It doesn't have to be a sales pitch, it might be a matter of availability. Back when there was a speed race, the fastest drives (both in motor speed and interface speed) were SCSI, and pretty much were only used in servers, except for the early adopters of computer audio recording (and long before anyone thought you could do video in the same manner). When I looked into a Turtle Beach 56K system (2 track editing, pre-Windows) a billion years ago, I was looking at about $2,500 for a SCSI drive because that was the only way you could get a drive as large as 650 MB, barely enough for a CD master. Today, 7200 RPM is pretty standard for full sized drives, 5400 RPM for laptop sized drives, and, because SATA is so much faster than parallel ATA, some full sized drives are available at 5400 RPM, which saves power and keeps them cooler (and probably also allows them to be built cheaper without risking in-warranty failures). Nobody using the drives for ordinary purposes, and few using them for extra-ordinary purposes, notices any more. Since there has to be something to distinguish real studio from "home" one, 7200 was one such thing, especially in days when 7200 were more expensive. I don't think that any studio really used that as an advertising point. But today there are more "home" studios that use laptop computers, which, by nature, usually have 5400 RPM drives. Some people would use external drives, but mostly as a matter of convenience for keeping individual projects separate, both for working and backup purposes. Those were mostly 7200 RPM just because of availability. Nowadays, if you buy a packaged external drive, it'll have a 5400 RPM drive inside the case to keep the cost and power requirements down. Also, there has to be something to make you change perfectly good HD for a new one. Usually that's a matter of capacity. You're recording more tracks and at greater bit depth and higher sample rate now than you were 20 years ago (because your computer can do it) so you need more disk space. That 120 GB drive you thought you'd never fill up is no longer big enough to hold a full album's worth of sessions with every take (even the bad ones, just in case) saved. With cheaper HDs labeled 7200 studios have to go elswhere to drive custommers in. Yeah. They have Waves plug-ins or API mic preamps or Neumann mics. Disk drives are a commodity these days.

sample rate question with 5400rpm hard drives
When comparing apples to apples, a 7200 is definitely a faster drive
than a 5400. I can tell the difference when upgrading from the latter with the same manufacturer's former, like I did last month on my MBP, and when I did the same on a bus powered FW drive which I use for backing stuff up to. But whether it'll will make a difference using X software and interface to record audio is a different story. And since there are good 5400 drives and not so good 7200 drives the water is muddied further. OP, what mechanism are you talking about? Any current model 5400 should acquit itself pretty well, a 5 year old one not so much. But set a big buffer and away you go. Wait, is this another one of those threads where someone asks a question and we answer it five different ways and then go off on a bunch of tangents and it grows to 200 posts and we start flaming each other, and meanwhile they never comeback? : ) |

That the computer boots up a little faster than with the original drive? Do you have files large enough to copy to or from a drive so that any noticeable difference really changes the way you work? If you're backing up 30 GB on a regular basis, does it make a difference between having time to eat lunch while it's chugging along compared to only having time to pee?

On Mon, 7 Mar 2011 17:55:36 -0800 (PST), in 'rec.audio.pro',
in article sample rate question with 5400rpm hard drives, Mr Soul wrote: On Mar 4, 6:03*pm, "William Sommerwerck" wrote: The rotational rate of the drive has nothing to do with the disk's areal density. Actually, it does, but only in the sense that you're not going to see drives of extremely high density spinning at high rates such as 15,000 rpm, as such a drive wouldn't be particularly reliable. As a general rule, the most reliable drives are those that spin slowly and have low areal density. Unfortunately, such drives have poor performance. In and of itself, it tells us nothing about how rapidly data can be laid down. This is true. The faster the rotation, the higher the transfer rate - so that implies to me that rotational speed is a factor. It certainly is a factor. I've done a lot of recording with 96/24 and it generates very large files. I would not want to be using a disk drive with less than 7200 RPM. The situation is that *both* areal density *and* rotational rate are factors, and that's why direct comparisons between different drives based only upon one of these factors are valid only when the other factor remains constant. IOW, for four different drives, all having identical areal density (and other factors such as the number of recording surfaces/heads), the slowest drive would be the 5400 rpm model, the next fastest would be the 7200 rpm model, next would be the 10,000 rpm model, and the fastest of them all would be the 15,000 rpm model. Similarly, for two drives both spinning at the same rate, the drive with the higher areal density would be the faster drive, again assuming that all other factors remained constant. What I think may be confusing people is that most of today's very low cost drives have, compared to what was available just a few years ago, extraordinarily high areal density. Because of this, it's not uncommon for a contemporary 5400 drive to outperform a 7200 drive of older vintage.

And as far as I know, the software and/or the drive would be buffered. Yes, eveything is buffered, but audio involves enough data that reasonably sized data buffers can't help a disk that can't keep up. |

That surprises me, too. I was, of course, trying to make the point that, in theory, high areal density should translate to rapid data transfer. That would be a joint goal of ours. However I had to proceed carefully, because I knew about the density problems associated with large relative velocities between the heads and the disk. Bottom line is that areal density increased rapidly *after* 7200 rpm drives became common. I believe that the reason for this was the switch over to perpendicular recording. http://en.wikipedia.org/wiki/Perpendicular_recording puts the switchover in 2005. "Perpendicular recording can deliver more than three times the storage density of traditional longitudinal recording." If that 3x bonus was manifest, then a 5400 rpm drive with perpendicular recording could beat an older 15,000 rpm drive. (!!!) It is not hard for a modern 5400 rpm drive to have higher DTR than an older 7200 rpm drive. Its not hard for a modern 7200 rpm drive to have higher DTR than an older 10,000 rpm drive, etc. I suspect that the 5400 rpm drives that came out shortly before perpendicular recording became common also had faster DTR than earlier 7200 rpm drives. |

sample rate question with 5400rpm hard drives
On Mar 7, 2:32*pm, Mike Rivers wrote:
What difference do you observe? That the computer boots up a little faster than with the original drive? Barely. Program opening speeds seem to be very slightly better, but might be the placebo effect. Do you have files large enough to copy to or from a drive so that any noticeable difference really changes the way you work? *If you're backing up 30 GB on a regular basis, does it make a difference between having time to eat lunch while it's chugging along compared to only having time to pee? I use the MBP mostly for Aperture and Photoshop, audio editing at home. Definitely an improvement when moving large folders of files but not a huge one like going from FW400 to 800. It doesn't change a lunch break to a pee break, but it shaves enough off to be noticeable. And there's a subtle but definite hint of more responsiveness in general poking around. Nothing eyeopening for sure but well worth the $65 and demoting the 5400 to a $15 enclosure. |

I believe that the reason for this was the switch over to perpendicular recording. http://en.wikipedia.org/wiki/Perpendicular_recording puts the switchover in 2005. That is correct. In fact, in May of 2006, I put up a quickie little Web page on this very subject, and named perpendicular recording technology as a primary reason for the sudden increase in storage capacity. I even contrasted the drives of May 2006 with an old Egghead advertisement from September 1997, where a spacious 1 GB drive was selling for a mere $99.93, referred to in the ad as "Our LOWEST PRICE ever!". I had found the ad in a stack of old audio/video magazines and since it was in such good shape physically, I just couldn't resist scanning it and putting it on a Web page.

My first hard drive was a Seagate 20 MB. Yes, that's megabytes. Cost over $660 including separate full-length controller. Looked like a great deal as just a year or two earlier, $800 got you 5 megabytes. |

Floppy drives started out in the $800 range as well. That would be a 180k, one-sided floppy. I was lucky, though, because for personal systems I would always salvage used drives from discarded machines at work, so that ultimately I don't recall ever having to pay those sort of prices for use in any system that I was building for myself. My first PC was paid for by some lucrative writing projects. I showed my kids how to do word processing early on. My kids were not allowed to turn in computer-printed papers because the teachers interpreted that as prima facae evidence that the paper was prepared by an adult. The quickly grasped the benefits of easy editing and wrote on the PC and hand copied their papers to turn in. Just for the record, I've never been a "dumpster diver" except for when it comes to electronics. Been there, done that. My most lucrative dumpster dive involved recovering 3 "Think Tanks" which were dictation recorders based on huge tape loops in huge vertical bins, maybe 4 square feet on a side. From these I recovered power supplies and gold contact telephone relays that were used to build many early prototype ABX Comparators. As for those full-length controller boards, I do indeed also remember those. My memory may be a bit faded on this, but I seem to recall that at least some of them had DIP switches on them that needed to be set properly before certain drives could function properly. Mine was delivered with an improperly burned ROM chip that put in so much allowance for seek delay that my 20 mSec access time Seagate ST 4026 ran at floppy-disk speeds. I was able to get a new ROM from the controller manufacturer rep in Chicago that got it up to speed. I also seem to recall reading "bad sector lists" off of printed labels on the drive so that the locations could be manually entered, else the drive might try to seek to a bad sector. Today, all drives handle this automatically, and know where spare sectors are located and when and how to use them - all done transparently to the user. To a degree. Modern drives can still let marginal sectors slip by and software utilities such as XP's CHKDSK can still be used to make unusuable drives marginally usable enough to get the data off of them. In more recent news, Sony has announced its new SR-R1 Memory Recorder for use primarily with its high-end HDCAM SR camcorders and cameras (SRW-9000, SRW-9000PL, F23, and F35).

It's not the price that was alarming on those, it's the total data loss. Well, they weren't exactly "low cost" drives, but it is certainly true that I never saw one last longer than about two years or so, and often just one year. They had severe reliability issues - and ran very hot. They were worthless garbage and they eventually led to Micropolis finally enjoying a well-deserved bankruptcy. The last Micropolis product I ever used was their unreliable floppy drive in the mid-seventies. I was quite surprised that they lasted into the gigabyte drive era, I was even more surprised that they were the first vendor that introduced a 9GB drive. But I wasn't surprised when they started dying like flies due to a design error. I wasn't especially surprised when the company went out of business. The 9GB drive basically put them out of business. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

My feeling, as someone who's been doing computers for forty years now, is that any analyst who believes that there's anything "rosy" about any of this simply doesn't fully comprehend the situation. Hitachi sold out because they couldn't take the heat any longer. My concern, if I were to have any, is that from an end user viewpoint, the choice has just gotten smaller, with Western Digital and Seagate, the later of which now also includes the former Maxtor operation, producing the bulk of the world's drives. I mean, who else, besides Seagate Technology and Western Digital Corporation (WDC), still makes HDDs? Fujitsu, Samsung, and Toshiba are all that come to my mind, and none of them hold a major piece of the pie. The Western Digital/Hitachi deal sets up the two companies (Seagate and WDC, that is) for a potential price-fixing situation, not that such a thing would ever occur, of course. -- Frank, Independent Consultant, New York, NY [Please remove 'nojunkmail.' from address to reply via e-mail.] Read Frank's thoughts on HDV at http://www.humanvalues.net/hdv/ [also covers AVCHD (including AVCCAM & NXCAM) and XDCAM EX]. |

sample rate question with 5400rpm hard drives
Wow, thanks everyone!
It looks like a bit of a Rip Van Winkle effect here. I was aware that hard drives have been offering ever-more amounts of memory at affordable prices. I didn't know that much had been improved in terms of data delivery density on 5400rpm drives. I haven't been studying them closely in about five years. It looks like a lot of the people here are saying that they complete 24/96 multi-track sessions on 5400rpm drive notebook computers without any problems. That makes my simple stereo track 24/96 or 24/192 look plenty easy for the drive to handle. |
