Never heard this before. I've been raid0 with intel 520 120GB + Kingston V300 120GB for my computer but never heard life span will shorten. First time see got ppl say like that.
http://www.tomshardware.com/answers/id-216...pan-drives.htmlI got find this answer from google but everybody think the opposite way "increase lifespan". Actually it does not affect much just combine them 120GB+120GB become 240GB. From the bios setting change from AHCI to RAID mode. Then when computer boot, a screen will comes out then press down CTRL+I to enter RAID settings.
I didn't see 'everybody' thinking that raid0 increases lifespan. Just one single poster whose response can be misunderstood - which you did misunderstand. To make it simple for you, raid0 of 2 smaller ssds will not increase longevity over a single bigger ssd.
And the last poster in that thread pointed out- "The effect of RAID0 to failure rates is not simple addition. RAID0 on SSD's in particular accelerates failure rates well beyond normal operation.
It also has very little real world performance impact outside of synthetic sequential benchmarks.
RAID0 for SSD's is almost never preferable over 1 SSD of the combined size.
The implications are radically different for RAID0 on an SSD VS on hard drives in reliability and performance."
I don't think raid0 accelerates failure rates but its true that real world performance for typical end users aren't greatly improved. Probably because real world tasks aren't mostly sequential read operations, aren't intensive enough, and limitations on the sata6gb interface to a lesser extent.

Most people not aware about "RAID 0" due to their computer knowledge still not reach until advanced level. If you are smart enough, RAID 0 two 120GB SSD is better than a single 240GB. SSD is not HDD, their lifespan is better than HDD. I thought you should misunderstand about decrease lifespan. Before SSD exist in this world, last time we are RAID0 two or more HDD. HDD is not same like SSD, when one of the HDD faulty then the rest HDD will all lost it data. However, SSD is different from HDD. So, why don't you RAID it?
With RAID 0, I can get 1000mb/s reading speed instead of the normal AHCI 500mb/s reading speed.
I've talked about your faulty comments about ssd/hdd lifespan earlier and in my post above this. Raid0 will double the risk of failure whether you are using 2 ssds or hdds (so ssds are not different from hdds).
