Okay. What about this? 4 480GB SSDs in a RAID 5. 2TB total. I'm connecting to a Mac Pro with Thunderbolt 2. ""Up to 991 MB/s read and 868 MB/s write sustained RAID 5 performance"

Thoughts?

I have these:
Crucial M500 240GB SATA 6Gbps 2.5" Internal SSD
I think they come in larger sizes also, here are some reviews.

composerjohn, you may want to get another external drive and alternate their use. Not only does this reduce risk, it means one of your backups is offline. An offline backup is not subject to crap coming from your computer or from voltage spikes, provided you unplug both the data and the power cables when it is lying fallow.

I think on composerjohn's scale, RAID 5 is just as good now as it used to be for us in the data center. The array is small, and the drives are small. Not only that, a rebuild should be fast, which reduces the risk of the type of crash that occurs during a RAID rebuild. I think RAID 10 and RAID 6 are overkill for him. As I said, I use RAID 6 on my job, but I have big arrays, and I have hundreds or thousands of people relying on the data (I work at a college), so we really can't afford crashes.

Any other recommendations for fast and reliable SSDs? I need at least 500MB/sec read speed. Thanks!
