I have an SSD array on a PCIe card like this: https://www.amazon.com/gp/product/B00KKO6N98/ I'm getting ready to retire my old late 2008 MacPro but I want to keep the SSD drives (I haven't figured out what I'll migrate too yet, but it's pretty sure that it won't have an internal expansion slot). Any thoughts on the right approach and good products that would let me do this? I'm also not entirely sure if RAID is the right approach with SSDs. Speed is nice, of course, and this card was definitely faster than individual drives, but I know most RAID setups assume rotating media and the special maintenance requirements of SSDs may cause them to not behave optimally-- so I'd entertain alternative ways to aggregate the storage of 4 separate drives into one volume and optimize performance. This drive mostly stores media files-- it's not my boot drive. One solution would be an external PCIe enclosure that I could attach by Thunderbolt and insert this card into. That would let me use the entire setup unchanged without having copy the data off and back when I rebuild the array. The downside is that I think I'm currently bus limited on performance. Still, on net, this may be the best option. Any thoughts?
