Hard Drives Evaluated for Noise, Heat and Performance

Sander Sassen writes "Ever wondered what harddisks offer the best combination of performance and low noise? Hardware Analysis evaluates all recent 5400 and 7200-rpm harddisks and focuses on noise, heat production and overall performance. Their results show that 7200-rpm spindle speed is no guarantee for high-performance and that low-noise and high-performance is not an impossible combination with some harddisks."

      On a drive with a three year warranty, you could cause a drive failure and send it in. The drive company would then send you a replacement. However, since your drive is three years old, they do not have them in stock anymore and instead give you the smallest one they have - which is twice as large as the one they are replacing.

      The end result is that every drive warrantied for three years might as well be advertised as "Free upgrade in three years". This slogan gives the bean-counters fits.

      Big problem for distributors in Europe... Here the law requires every seller to warrant the usability of technical equipment (at least) for two years. If the manufacturer doesn't give those two years of warranty on the sold equipment, the seller has to keep a stock of the equipment just to replace the failed ones. So either the manufacturer gives two years of warranty to the distributor, or the distributor walks over to a manufacturer who does. Or he stops selling harddrives. Either way the manufacturer looses.


      Same is of course valid for ready built computers, not only single parts. Assemblers have either give a warranty for at least two years or the distributor looks for someone who does. In the tight market with sliding sales I doubt the assemblers or the manufacturers will be able to close shoulders and stand the urge from distribution channels to give two years of warranty.

      More and more as time goes by (and drive size increases, and prices drop) I'm seeing much higher percentages of drives with manufacturing defects, or drives that develop errors after several months of typical (home, office, small business, small enterprise server, etc.) use.

      I don't even have to resort to 'naming names' - they're all proving bad lately. It's not just our equipment, either. We're handling (on behalf of our customers) RMAs for several different computer resellers in our area, most of whom do not use our supplier(s).

      I'm sure anybody would understand the significance of this problem after you've told your tenth customer in a month that their data is irretreivable, AND that they have to wait 4-6 weeks for a new unit or purchase a new one. (Don't even mention data recovery - Joe Homeuser or Suzy Smallbusiness just can't afford thousands of dollars, but it doesn't make their data any less important than a mega-corporation)

Scandisk froze solid when attempting to diagnose it, so I slave mounted it and began extracting data. After about 200MB or thereabouts, it made the loudest screeching noise I think I've ever heard.

      The drive was manufactured less than two years ago, purchased only 1.5 years back.

      It's a sad state that the computer industry is in right now, with most components suffering the same fate as hard disk drives. I must replace two power supplies per week, it seems. Granted, we're making a killing on labour on all this defective hardware (why the stores they purchased this equipment from won't help them, I'll never know, and I'm too frightened to investigate) - which, in hindsight, is probably the reason behind the "So what if it only lasts for one year?" line of thinking.

      If manufacturers don't have refurb drives or services available, or if they won't replace a defective unit with the next-closest-piece available; that's not our problem, it's clearly a problem with their company policy. Being mechanical, drives are easy enough to repair.

They gave me the number and I shipped it to them four days after the manufacturer warranty expired.

      Like other people have replied already, tolerances are the issue. The gap between the head and disk during operation of the drive is crazy small. The wobble in the spindle bearing is easily more than this gap, if your head was in a fixed position at one point it would be too far away from the surface to operate, at another it would be digging into the surface. The only real solution is to have it fly above the surface. If it flies too high then there won't be enough lift and it will fly lower, if it flies too low then there will be extra lift so it flies higher. It is a continuously adjusting system based on the flow of air in the drive and it certainly works quite well.

BUT - we need to remember that heat produced is not directly responsible for the failure of the drive. It is ultimately the temperature of the electronics (and its fluctuations) that are directly responsible for the drive's failure.

      Thus, when surface temperature measurements done by probes prove unreliable, it might make sense to have an internally mounted temperature sensor to determine actual drive component temperature. In fact, it would be pretty simple for a manufacturer to implement a control circuit for drive RPM speed based on internal drive temperature (which can be probed fairly accurately).

      Getting back to the main point - I do believe that surface temperatures can be better than "HORRIBLY unreliable". But for meaningful comparisons to be made, drives need to be tested in similar machines, and the ambient temperature must be noted for each instance. Remember - when it comes to heat transfer, the absolute temperature of an object will never determine heat transfer. It's all about the delta T.

    IntroductionBy: Sander Sassen

    A modern harddisk is not that different, mechanically, from the first generation of harddisks that debuted with the IBM PC in the '80s. Today's harddisks are also mechanical parts that use spinning platters and read/write heads to store or read information from them. That also explains why harddisks haven't seen the rapid pace of innovation as for example CPUs have; simply because the mechanics are holding the harddisk back from making similar leaps in performance. But to be honest that's not entirely accurate, modern harddisks could be substantially faster, but not without either driving up the price significantly or introducing unwanted side effects.

    One of these side effects is excessive noise; because a harddisk has a number of spinning and moving parts it is virtually impossible to make a harddisk noiseless. Anything you'll do to counter the noise will either influence the performance, drive up the price, or make the harddisk physically larger. For example one way to reduce the noise would be to reduce the rpm of the platters which would mean we'd end up with a slower harddisk overall. And vice versa, by increasing the rpm of the platters we'll get a better performing harddisk but the noise level will also increase.

    Naturally we could counter the noise production by adding sound insulation. Unfortunately insulation is not the preferred way of tackling the noise production as it'll make the harddisk physically larger, and thus leave less room for storage capacity. Furthermore it also works as an insulator for the heat produced by the harddisk, which would then cut into the harddisk's MTBF, Mean Time Before Failure. That actually brings us to the second unwanted side effect of high-performance harddisks and that's excessive heat production.

    Modern IDE harddisks feature platters that revolve at either 5400 or 7200-rpm and thus revolve at about half the speed of the fastest SCSI harddisks that top out at 15.000-rpm. The main difference is that these SCSI harddisks are used in professional applications such as database servers where noise- and heat production are second to performance, and thus these levels are substantially higher than consumer level products. In consumer level PCs however heat production is becoming an increasingly important issue. PCs continue to get smaller and CPUs on average dissipate more than 50-watts of heat, so the system temperature will rise significantly if a harddisk is mounted with excessive heat production. In the following pages we'll take a look at all recent 5400 and 7200-rpm harddisks from IBM, Maxtor, Western Digital, Seagate and Samsung with a focus on noise and heat production as well as overall performance.

    Noise ProductionBy: Sander Sassen

    As mentioned a modern harddisk still is a mechanical device, and as with most mechanical devices it is hard to completely cancel out all noise. One part that contributes to the noise significantly is the spindle, which drives the platters. The spindle is usually direct-driven and has an rpm of 5400 or 7200-rpm, which translates itself into a high-pitched whine. Harddisks that use high-quality bearings or even fluid-bearings are less noisy in this respect than others that use conventional bearings. Then there are the harddisk platters; due to the high speed at which they revolve they generate both noise and heat. And naturally the more platters, higher capacity harddisks, the more heat and noise are generated. Due to space constraints modern harddisks don't use more than four platters which does limit the heat and noise production to a certain level.

    Fortunately a manufacturer has a number of options at hand to reduce the noise level of the spindle and platters, such as using high-quality bearings or decoupling the spindle and spindle-motor from the harddisk casing by using a sound and vibration dampening gasket. Of course another way to reduce the noise and heat production would be to use less platters of a higher density, as this will not influence the storage capacity of the disk.

    Fig 1. The interior of a typical harddisk whilst operating. This movie requires the Windows Media player to be installed and requires a broadband connection for streaming playback.

    But there's other moving parts that also contribute to a harddisk's noise production; the read/write heads are notorious for causing the 'rattling sound' many harddisks make when accessing your data. And again the manufacturer has a number of options to reduce this noise which usually mean that the heads are operated less abruptly when sweeping across the platters. For example by smoothing out read/write operations by slowing the heads down when they need to reverse direction or by intelligently combining read and write operations and thus reducing head movement. Unfortunately many of these noise reducing measures do affect the harddisk' performance and some can even be set arbitrarily through software to optimize for a specific application.

    Heat ProductionBy: Sander Sassen

    Any part that is operated above its maximum temperature rating over a prolonged period of time will see its MTBF drastically lowered. All parts that make up a modern PC have such a maximum temperature rating, most of which are around 50...65 degrees Celsius, or 122...149 degrees Fahrenheit. An average CPU dissipates about 50-watts of heat inside a PC case and is one of the major contributors to a rise in system temperature which could easily be as high as 45 C/ 113 F. If the case temperature is already that high, some of the parts of the PC could already be operating at or above their maximum temperature rating.

    Especially 7200-rpm harddisks are suspect as they are known to get substantially hotter than their 5400-rpm counterparts. Naturally 7200-rpm and multiple platters all contribute to more heat being produced, as the spinning platters get hot due to the friction with the surrounding air, the more platters and the higher the rpm, the more heat. Unfortunately we can't simply say that 7200-rpm harddisks get hotter than 5400-rpm harddisks by default as our measurements will clearly show, but we'll get to that in the next few pages.

    Harddisk Interior

    Fig 2. The interior of a typical 80GB 7200-rpm harddisk, in this case a Maxtor D740X. This harddisk features two platters with 40GB/platter density.

    What is important to consider though is the question whether the harddisk doesn't get too hot when mounted inside the PC. Most modern harddisks have a maximum operating temperature ranging from 55 to 65 C or 131 to 149 F, and if operated above that temperature you're really putting yourself at risk of losing valuable data or a harddisk malfunction. If the system temperature is already at 45 C/ 113 F the harddisk could very well be operating over it's maximum temperature, which will cut into the disk's MTBF and reliability significantly.

    The easiest fix: Take some foam padding, preferably the antistatic kind that most hardware ships in these days, and line your case panels with a layer or two. It'll cut down on a good portion of the noise, and it'll improve your airflow (you didn't really think that air was supposed to go through those decorative holes, did you?) Be sure to keep it thin on the back side, next to the mobo. I know it says antistatic on the box, but do you really want anything touching your mobo?

    Next, replace your damn PSU. Standard ones are way too damn noisy. I don't have any links handy (I'm at work), but they are plentiful and easy to find. Oh, and say "damn" alot. It helps.

    Getting more in-depth, remove your peripheral drives (CD, HD, etc), and put them back in with rubber washers both between the drive and case, and between the screw and case. It cuts down on vibrations significantly.

    Tie up your loose cables. Sounds silly, but I've found that in several systems with significant airflow, they were either moving around or causing turbulence. Either make or buy rounded IDE cables for the best flow.

    If you have a very noisy harddrive, yank it from that small and normally loose 3 1/2" bracket and put it in one of your 5 1/4" bays with the help of drive brackets. Insulate around it with antistatic foam padding, use rubber washers, put an ultraquiet mini fan behind it, set to pull air(that old socket 7 fan you have lying around will do just fine). Finally, remove the bezel in front of it, drill some small holes for airflow, insulate with foam padding (remove the padding around the holes ((yes, it is sad that I have to point that out)) ), and pop it back in. Voila! Thicker padding to cut down on sound, it's in the 5 1/4" drive section, which I find is much sturdier and less prone to rattle, and the fan will keep it cooler than it would have been before.

    Consider dropping that 52x CD. Sure, it's impressive, but you install all your games with max install, right? (right??) Or better yet, go buy software that will copy your CD to the HD and then subst the directory to a drive letter. Voila! CD at HD speeds. Replace the 52 with something more conservative, and you'll notice a big difference (and lower spinup time)

    crud, "subst", I just dated myself...

    Consider spring-mount screws for your case fans. I have a whole bag of them, but I'll be darned if I can remember who made them. They're basically just a short metal or plastic spring with a screw at each end. One end screws into the hole on the fan, the other into the case, voila, instant buffer against vibrations.

    If things are still too bad for you, consider an external case mod. The quietest I ever did was to replace all of the metal panels on the case with 1/2" beechwood (damn, but it was pretty), but not all of us have the time and patience to work up something like that. The easiest is to take your panels off, and slap some starch/water paste on them. Next, take some thick cloth (or a few layers of thin cloth, if you feel the need to be difficult), load it up with the paste, and then just slap it on your panel. Make sure it's all wrinkly and folded n' chit. Let it dry, and the cloth should stick on just fine, adding another layer of sound barrier for ya. DISCLAIMER 1: This has been known not to stick on some of the new, shiny, smooth cases. DISCLAIMER 2: Take the panels off of your PC BEFORE you start slathering them with starch. Or, at the very least, remember to turn your PC off first. ;-)

    Finally, try putting your PC on a phone book or something similar. Sounds silly, but it dulls the noise that resonates into the floor/desk. If it makes a difference for you, then build something more permanant for your case to sit on (or, at the very least, give it some ultracool extra-long legs like the AT-AT Walkers from Star Wars.... complete with little lazer guns on the CD drive... )

    Lastly, note that a heckuvalot of the noise you hear could be from your monitor, too. But I will avoid monitor mods for today, lest some yahoo stick a phillips through his tube and show up at my doorstep, ready to share the tale. (it's happened, and I swear he was still smoking).

One would have to actually measure many samples (the tighter the interval the more accurate the total draw) as surely no drive is going to be consistent in its energy draw: I would imagine it would constantly fluctuate by 100% or more as the drive does different access patterns, etc, not just hooking up a radio shack multimeter and eyeballing the draw. The net result though would be an extremely accurate gauge of the true power draw, and hence energy discharge, of the hard drive (easily as accurate as putting the draw in a controlled environment: It isn't generating heat magically).
