dear forum users

please help me find a best solution for my new built gaming rig. I am not worried about space but i need top notch performance.
Therefore i have selected 2 drives i dont know which one peforms better(help) or suggest a better drive

2 * Raid 0 500gb 7200rpm 32Mb cache - http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Or

single hard drive wd 10000rpm 150gb 16mb cache - http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I actually had a post asking a similar thing. I wasn't sure whether to go for a velociraptor or one of the Seagate enterprise drives and put them in RAID. So far, only one person responded and told me to get a WD Caviar Black. I've heard good things about it and I will likely use that as a storage drive in a addition to Intel's SSD when it comes out.

the old raptors suck compared to modern drives. if your choosing between the raptor (not velociraptor) and any modern 7k rpm drive then go with the 7k drive and get more storage. HDD speeds make little to no difference in games. I would go with a good 1tb.

Hi OP

Your real choice is 15K RPM SAS drives (or 2nd hand 15K U320 SCSI drives) vs. 7200 SATA drives (until SSDs hit the right price). 15K SAS or U320 drives will need a controller card (start at around 200 USD) so is not the cheapest option.

e.g.
SAS/SATA Controller:

70.00 USD

150Gb 15K SAS drive:

235.00 USD

So quite a lot more than the Raptor (double the price by my reckoning). You can find better deals for HDs on Ebay, etc. of course (I didn't try too hard). If you can't afford SAS then go for the SATA drives you were originally suggesting.

Also folk are offloading U320 SCSI drives these days. I recently picked up a second hand 150Gb U320 15K drive for about 100 USD (equivalent in GBP) on Ebay.

10K rpm drives offer only a minor improvement over modern 7,200 rpm drives. In days gone by I always built machines for other people with Raptors if they had the budget... This is no longer the best way to eek out top notch performance.

No one here bothered to check the links except me. The link for the "WD 10000 RPM 16 MB" hard drive is the new 150 GB velociraptor, not the old raptor. Rofl. Clearly, if he's looking at getting the 150GB velociraptor, there must be some sort of budget restriction. SCSI is out the the question.

I too am curious to know how the smaller velociraptor would perform versus it's larger brother.

Should be the same performance, just one platter instead of two.

No actually the Velociraptor is a goer (my bad I had checked the links but had forgotten the performance advantage). It matches a lot of 15K 2.5" drives. The access time is really low and the high ariel density overcomes the inate disadvantage of the 2.5" platter size (150Gb/platter).

My original comment stands about it not beating modern 3.5" 15K SAS drives. However it would appear to beat the 3.5" 1TB 7200 RPM Samsung F1 by a wide enough margin to consider it as a boot drive (the Windows XP startup performance is v. good).
