Two Low-Performance SSDs in RAID 0 or One High-performance SSD?
Q1.Which is better: 2x Low performance (128 GB) SSD drive in RAID 0 or one High performance (240 GB) SSD drive??
Q2.Can you do a benchmark on this?
eg: 2* OCZ Petrol SATA III 2.5" SSD 128GB in RAID 0
Max Performance for 1 SSD:
Max Read: up to 360MB/s
Max Write: up to 180MB/s
Random Write 4KB: 14,500 IOPS
Random Read 4KB: 32,000 IOPS
1* OCZ Agility 3 SATA III 2.5" SSD 240GB
Max Read: up to 525MB/s
Max Write: up to 500MB/s
Random Write 4KB: 45,000 IOPS
Maximum 4K Random Write: 85,000 IOPS

Depends heavily on what you intend to use the SSD for.
In terms of subjective performance, most decent SSDs are pretty much the same. That's because differences are measured in fractions of of second or at best a couple seconds. If SSD #1 takes 1 second to load a program and SSD #2 takes .5 second to load the same program, SSD#2 is technically twice as fast, but the actual experience is pretty underwhelming. If you're moving really large files, you'll probably notice the difference more as minor speed differences add up over gigabytes of data.
If you're using this as a boot disk, a 64/60gb SSD works fine. If you're using it for programs, I think a single large SSD is better.
