Nothing that is noticeable in the real world, just synthetic benchmarks. However if you can get 2 120gb drives for cheaper than a 240, than go with raid 0.

RAID 0 will technically give you twice the performance, though given the speed of SSDs it really would be a waste of money if its just browser load times you're worried about. When buying storage media, especially SSDs, always take storage capacity over speed. SSD speeds will blow you away as is, and there is nothing worse than realising you need more space 3 months down the road.

For practical purpose, those times and speeds you will notice, a 240GB SSD will outperform a 120GB, as they are always slightly faster. The RAID0 perofrmance will only benefit the extreme benchmarks... Not anything you will need. So, if you only need 120, go 120. If you think you need more, don't RAID but buy a single, larger SSD...

If you're frequently transferring large files, then you'll definitely benefit from RAID 0. But a single drive is safer, though it's hard for an SSD to just up and die...

Really it comes down to cost. If you can get two 128GB SSDs for less than a 256GB SSD, then go for the RAID, and vice-versa. Either way you won't be disappointed.

I would probably stick with one 240 vs 2 120s in raid 0....as long as you dont do extreme editting/ rendering you wont notice a big difference.

Ill do things differently

say you have a mean failure rate of 2years (that is to say after 2 years half your drives fail) per ssd.

if you have 1 drive running for two years then its a simple 50% likelihood of failing however.

if you have two drives in raid 0 then after 2 years the likely hood of one of the two drives is twice as likely i.e. after 2 years you have a 25% change your drives are still working.

I was going to buy two Corsair Neutron GTX 120Gb SSD's and put them in RAID0. Now I red somewhere that the 240Gb version is much faster. Should i still buy 2 120Gb's or just the one 240Gb version.

I would defently just go with a single 240gb, its still a 10x performance boost over a regular hard drive

ok thanks, but is the 120gb really slower than the 240gb?

unless you are working with huge files like HD videos or stuff like that or need a fast storage medium for recording high resolution videos with losless quality with a capture card. the the RAID 0 will help you a lot. but other than that for everyday usage and gaming and what not. just get a single high capacity drive. because it have less chance of fail and loss of data.

RAID is most useful when using with HDDs.

A single SSD will out perform any raid config out there, It's up to you if you want to buy 1 large capacity SSD or buy 2 to get around the same. In my opinion it's not worth buying 2 SSD's if you can afford 1 higher capacity SSD

i think you shouldn't do raid exept if you have a raid card to realy inprove performance. i would get a high end ssd instead of two lower grade ssd's and a raid card #justmyfilosophy
