Span, Stripe, or leave them alone? :O?
I need a 2 TB SSD. The biggest you can get is usually 1 TB (Yes, I know one company makes 2 TB ones, but they're too expensive. I'm sticking with Crucial - I have 3 of them now (one 512 MB for OS and programs, two 1 TB for data). Anyway, I now have two 1 TB SSDs. What should I do - Span them, Stripe them, or use them separately? GIVE REASON! :)
Thank you! ~Cindy! :)

If you can manage the space between the two, then using them individually allows them to be backed up individually, replaced individually, fail individually - SSDs can and do fail, the flash media has a finite number of write cycles, though unless being write-hammered, they should easily outlast hard disks.
To make a single bigger drive, then stripe (RAID 0) leverages the throughput of both drives simultaneously. One issue though, some RAID implementations cannot perform trim operations, so the drives will lose some write performance if that is the case.
Trim is the function which queues deleted blocks to be background erased and added to the free pool, without it, blocks are only cleared on demand.
