Hard Drive Overclocking Competition From Secau

Blittzed writes "We were reminiscing about the good old days of overclocking CPUs and memory, and the subject of hard drive overcloking came up. The discussion / argument we were having in the research lab ended up in a bet which now has to be settled. So, we are putting our money where our mouth is, and putting up $10,000 to anyone who can read a 500GB drive in under an hour. We will also consider other attempts with a smaller amount of money in the event that the one hour is not possible. There are a few rules (e.g. the drive still needs to work afterwards), but otherwise nothing is ruled out. Specific details can be found on the URL. Go let the white smoke out!"

      I have a much better question....why? While I don't know if it is the same with Linux (I gave up messing with it around Ubuntu 10.4, but I'll assume it is) with Windows and the frankly insane amounts of cache one gets on a drive nowadays combined with Superfetch one will rarely notice your drive! In fact lately I've been using 5900RPM drives as OS drives because with 64Mb caches and plenty of RAM there just isn't enough of a difference in speed to deal with the extra noise and heat, especially if the customer wants it as an HTPC.

      So honestly I don't get it. you OC a CPU (or in the case of AMD unlock cores as well as OC) because you get a more expensive CPU at a cheaper price. Same thing with RAM or flashing an HD4830 into an HD4850 which I have done a couple of times so far and works well. But with HDDs you simply add a second in RAID 0 or if you don't mind dealing with the hot/crazy scale and the possibility you may be spending several hundred a year on replacements and be risking data? Well then go SSD. But it isn't like OCing that EcoDrive is gonna turn the thing into a Velociraptor, it is just gonna wear the thing out quicker for less gain than you would have seen adding a RAM stick. I just don't get it, folks with more time on their hands than they know what to do with I guess.

In the end it doesn't change the fact that unlike CPUs and GPUs and RAM where you are just pushing electrons through silicon with a HDD you are dealing with a mechanical device that has been built and testing for a certain rotational speed with a certain MTBF and by pushing that you are in essence redlining your car and hoping the engine doesn't blow.

      So it doesn't make any sense. With GPU, CPU and RAM you can use better cooling to drop the temp and allow more electrons through without damage. No matter what kind of fins you add with a HDD you still aren't gonna get close enough to that motor to matter and you are already talking 10,000RPM on a performance drive. There is a GOOD reason why we don't see 20,000RPM drives and that is because we are already at the limit and increasing spin is simply gonna add instability and increase risk of failure.

      And how many other than you use Multi-TB scratch drives? I bet its a teeny tiny niche at best. Not to mention if you are running machines that actually need multi-Tb scratch drives then I bet you have the money for 15k RPM drives or SSDs as machines running that much data through them are making serious $$$ for a company. So in the end this just doesn't make a lick of sense. It can't in any real way be used practically as it increases the risk of failure too much so at best you can say its a "for shits and giggles" test like running your AMD quad on liquid helium to reach 7.6GHz.

      Any disk cache falls apart once your data set passes the size of available ram and then performance drops to the performance of the hard drive itself. There is also the issue of any caching mechanism adds overhead, and if you get allot of misses the performance benefit is almost completely negated, all you need is a somewhat random I/O pattern and it goes to hell.

      If we bring this argument down to the common person on the street, will they see a difference if you upgrade the processor? probably not, ram? beyond a certain point nope (pass 2GB now a days and most can't see much difference), PCI-E 3.0 / SATA 3.0 / USB 3.0?

One head's fine if your disk isn't ridiculously fragmented (which it won't be); you have RAM to buffer it while the drive seeks occasionally (e.g. past a file fragment to the next unallocated space), then it'll catch up. But now suppose you want to playback a timeshifted stream of this same bandwidth -- even if you jump to RAID0 with two disks, thus doubling your throughput, you should have plenty of time to read/write. Only now you're seeking back and forth, and that latency really digs into your throughput. Maybe if you add 2 or 3 disks, it'lll work; maybe if you have enough RAM for huge buffers and a properly tuned I/O scheduler, you can read and write in big enough chunks to minimize the seek penalty. But a 2-headed hard drive will do just fine, and (at equivalent quantities) would be even cheaper than 2 identical drives, and similarly priced to 2 half-capacity drives for the RAID0 setup. Of course, since very few applications fit that profile, quantities are not the same, and RAID0 with however many disks you end up needing is still cheaper.

      So there is some sense in a dual-headed drive for very specific applications (something like DVR is the most obvious thing, but anywhere you have a real-time writing requirement where bandwidth is a significant fraction of drive throughput AND you can't put it on a separate drive from other IO), but there's nowhere near enough of those applications to justify it.

      That said, in the interest of pedantry: Unlike a striped RAID 0, a RAID 1 array of n+1 disks could conceivably perform as a single disk with multiple heads, since a RAID 1 of n+1 has n+1 worth of independent head stacks, all reading identical data.

I think this behavior is present in most quality RAID-1 controllers, I'm surprised md doesn't do it too.

      Without physically raising the spindle speed, I do not believe it will be possible to lower the time to read the entire drive significantly. The spindle speed is no doubt frequency locked to an on-board oscillator so I might try swapping the controller board with one modified for a higher spindle speed and then reading the drive. There are a couple of ways to go about that including raising the frequency of the reference oscillator or changing the phase locked loop divider that the spindle motor driver uses. RPM detection no doubt uses back emf sensing so fiddling with the spindle position sensing is not an option.

      All of this will be for naught though if the read channel will not operate at the higher frequencies involved and the drive may simple fail during calibration or detect an out of scope parameter and shut down.

Structured disks are rather unnecessary with smart controllers and huge memory sizes. Read the whole track, modify in memory, write the whole track. Back when disks were actually much larger than machine memories, it made sense to have formatted disks. These days, you can buy flash that's comparable in size that could fit on a controller easily and a single bank of RAM is more than sufficient to handle track-at-once operations on individual drives.

    If any controller is allowed, roll your own. You want the lowest-level operations offloaded from the CPU (which is slow) and you want the buffers written direct to memory rather than via the kernel (so you want a bus controller on there).
