Hi guys, some advice please, price vs performance,

I currently have 2x Western Digital Caviar Blacks (WD6401AALS) from a couple of years ago set up as RAID 0 bought from ocuk, which I use to load games from, however they aren't quite as quick as I'd like, so I would like to upgrade them. Size wise they are both roughly half full (split into 2 partitions, for speed benefits, important data backed up elsewhere).

It's more to fiddle then because they aren't working and they will be reused elsewhere in other computers, but I'd like a speed increase really, won't match my SSD (which I am not currently using for games) and unless there is a large SSD floating about somewhere sub-£100 then I don't want one, I need a cheaper, larger size solution.

I looked at the Seagate XT Hybrid 500GB, but not sure that I'll get enough increase in speed, and at RAIDING either 2x Seagate 7200.12 (@ 500GB Each) or WD Black 500GB or 750GB (32mb vs 64mb cache however). The seagates are cheap, but not sure how they'd compare speedwise, I already have a Seagate 7200.11 for Media files and it performs fine.

So, what would you all suggest? I am currently using about 260GB for games and other data, then I'd need some space for the secondary OS too. If it gives suitable speed improvements over what I have I'd consider a single 1 or 2TB drive instead of RAID0 as long as it's cheap.

Thanks for any advice guys. :)
 
Ok done a HD Tune test.

Transfer Rates: Min = 113.3MB/sec. Max = 210.3MB/sec. Average = 174.8MB/sec
Access Time: 12ms.
Burst Rate = 134.7MB/sec.
CPU Useage = -1%

Not bad I know, just want to see if I can get quicker loading times, with a higher storage device (yes, my SSD is quicker, but it's used more for Windows and Steam itself for example).

The SSD (Intel 510)
Transfer Rates: Min = 208.1MB/sec. Max = 215.3MB/sec. Average = 211.9MB/sec
Access Time: 0.2ms.
Burst Rate = 175.0MB/sec.
CPU Useage = -1%

Both are running on a Sata 2 Intel Controller, built into the motherboard.

No single HDD is going to even match the speed of your RAID 0.

Two 1TB Samsung F3's in RAID 0 (about as fast as you'll get with 2 disks) look like this:



It's up to you if it's worth shelling out for and there might not be much real world difference.

Thanks for that mate, may just save the money and use it to get a new gfx card tbh :)
