Hi, my Pny 240GB XLR8 already is full of data and there's no longer another one of the same model available here in Brazil. I found another Pny 240GB, but CS1100 model, which is a little bit slower than the Xlr8. Specs below.

Read : Xlr8 - up to 500 mb/s > CS1100 - up to 430 mb/s
Write: Xlr8 - up to 430 mb/s > CS1100 - up to 300 mb/s

I know the Raid 0 would be limited by the slowest ssd, right ? Do you think doing this raid 0 would be a better choice than buying an intel 535 120gb (read/520, write/480) ? Because here the Pny 240gb is much more cheaper than the others 240gb models and the intel 535 120gb is the best ssd for the money. The Pny 240gb is only a little more expensive than intel 120gb, so what would you do in this case ? Please, I need good advices :wahoo:

Unless you're doing work which frequently access large files (e.g. real-time video editing), don't bother trying to RAID 0 SSDs. A lot of times it ends up slower than a single SSD for non-sequential file accesses.

RAID 0 performs better in most of the synthetic benchmarks, but a single drive is faster than or indistinguishable from RAID 0 in the real-world tests. The reason is SSDs are so fast, the overhead of running RAID 0 (splitting every file into two, and gluing them back together again) costs you more time than you gain by reading/writing the file in parallel.

Also, unless you're working with large files (sequential read/writes), just ignore the sequential...

Also, unless you're working with large files (sequential read/writes), just ignore the sequential speeds of the SSD. Compare the 4k speeds and IOPS - that's where most of the speed of the SSD comes from.
