On the other, I’m not sure I’ll notice the difference with my usual use case, and I’m trying to keep this retrofit not too expensive. I’m wrestling with this on the one hand it’s “only” $38 and will double my hard drive performance. I think I’m going to pick up two of the latter to have a complete system. There are $10 adapters that will re-use the existing sleds for SSDs, or whole-sled replacements for $15. I have all four silver aluminum drive sleds for the Mac Pro, but two are pretty gnarly.Dealing with specialty apps ( Tree is the only one I can’t find a ready replacement for, but I haven’t looked very hard), buying updated versions of others ( Scrivener, to version 3 Clean Text), for 64-bit compatibility, is a bit of a nuisance, but survivable (and expected).

According to sysctl -a | grep brand, the CPU is an Intel(R) Xeon(R) CPU X5680 3.33GHz a/k/a a Westmere, so that’s one upgrade I don’t have to worry about (I’ve heard of folks having issues, most notably with audio, with the older Nehalem chips).
