Would having two 120 Gb SSD's in Raid 0 be any benefit? That way I would have 240Gb of fast storage right?

And do I have to match drives?

And what is the limiting factor for data transfer rates in a raid setup (is it chip, board, drives)?

No, don't do RAID SSDs.... virtually no benefit nearly the double data loss rate.

Using two SSD's in RAID 0 will be faster, but when you're talking about SSD's, I've never seen the point. A single SSD by itself is pretty darn fast already. RAID 0 makes more sense when using HDD's.

I've used SSHD's in desktop systems before, and they provide a performance boost, but it's more along the lines of the boost you'd get from using a Raptor than the boost you get from an SSD. An SSHD is best used in laptops where a lot of storage is required and there's only room to install one drive.

You don't have to match drives but it's usually a good idea so one drive doesn't bottleneck the other. As for limiting factor, with HDDs, it's the drives. With SSDs, SATA III is already a bottleneck. If you RAID-0 a whole bunch of fast SSDs (e.g. Samsung 840 PRO), you'll further hit a motherboard bottleneck (well, DMI link to CPU).

That said, a 128GB SSD for OS/programs and a 7200RPM HDD for programs/games set-up should for most folks.

Ok!!!!

I think I got this now, Do not raid SSD drives.

Best bet is a SSD and mech drive. Second best is putting two mech drives in a raid setup.

If wanting a fast one drive system and money is no object get a massive SSD otherwise if your a normal person get a Raptor.

Best bet in terms of a balance between price/performance, yes. Quite frankly, for OS use, HDDs in RAID-0 would still be far, far off from the performance of SSDs. The speed of SSDs is just in a totally different ballpark. If using two or more drives is an option, I'd always go with SSD+HDD.

Raptors are over-priced. Just get a WD10EZEX or ST1000DM003. Heck, those should actually give you better sequential than the VR 600GB and you can always short stroke for improved access times if you don't need all that space.

Truely a penalty for those individuals who purchased the 1TB 2.5" drives and didn't realise they were 5400 rpm drives! Kinda sneaky how RPM is not mentioned anywhere in the product listing, lol.wink.gif
