I have 4 SSD drives
- 2 identical old ones: Corsair SSD Extreme X32 2,5" 32GB - SATA2, read/write 220MB/135MB
- 2 identical new ones: Corsair CSSD-F40GB2-A Force Series 40GB, read/write 280MB/270MB
At the moment I have the 2 new ones as RAID0 and have installed my OS on that RAID0 setup. I also have the 2 old ones as RAID0 and was thinking I could use that drive as a temporary storage partition for current work, and caching for illustrator, lightroom, photoshop, picasa and some other software.
I'm wondering whether I'd just be better off putting all 4 drives into one big RAID0 array. I assume everything drops to the lowest common denominator, but potentially having 4xSSD's in a RAID0 running at the lower speed would still be more effective than 2xSSDs in RAID0 at a higher speed.
I believe another downside to running all 4xSSDs in a single RAID0 array is that I'd also lose storage space and would have a RAID0 array of 4x32GB.
Any advice/thoughts appreciated :)
PS. I won't be relying on these drives for any permanent data storage, that will fall to 2x2TB drives in RAID1.
