does any of you know what the fastest or few of the fastest low capacity 7200rpm hard drives are? With low capacity i mean anything under 500gb.
I tought higher density drives are faster, so single platters should be fastest, true or false?
The drive I'd go for, assuming you don't want something like a Velociraptor or SSD, is probably the Seagate 7200.12 500GB. It has a single 500GB platter, and will be faster than even the much-recommended WD 640.
i researched and yes the Seagate 7200.12 500GBe seems to be very fast. as well the western digital 500gb black 32mb cache.
i think western digital is more reliable than seagate. but seagate bit faster.
All companies have specs listed at their websites. If you want to go by just one number, look at the average read speed.
Seek times is a factor too but doesn't affect games at all. A large amount of data is buffered into your RAM and when the game needs more it loads but the data is contiguous so average read speed is most important.
Western digital has 3 drives you should look at:
2) 1TB Black
The Velociraptor is fast but expensive. I even used up all 300GB with games. The 1TB Black is huge (actually 930GB) and slightly slower but really a great deal.
Many people have used two 1TB Black WD's in a RAID0 configuration. That gives 1860GB of space for roughly $200 and games will load about twice as fast.
SSD's are still too expensive but I plan to get one in another year then install games onto my 2nd drive (a TB hard drive) when/if space runs out (so I'll install to D-drive).
you can not compare avg read speeds from vendors, because they each use a different machine and different methods making a comparison between the two figures worthless.
Velociraptors are the fastest standard drive (quite expensive though), then the 7200.12 (although i refuse to use seagate), followed very closely by the caviar black (which is what I put in all my builds)
The maximum read speed of a drive depends on where your data is located. The outer cylinders have more data per track, so at a constant 7200rpm or 10k rpm, they will transfer data faster than the inner cylinders. Currently, the fastest sata drive is the velociraptor. You can come close with the WD caviar black 1tb drive. The key is to plan on using only the fastest part of the drive. Here is a chart of the Maximum data transfer rates: http://www.storagereview.com/php/benchmark/bench_sort.p...
If you want to do much better, look into a couple of SSD's in raid-0. Be careful of which ssd's you look at, because many mlc drives use a controller with severe write issues. Also, the ssd is getting better daily, so it might be good to wait until the end of the year.
