Hey guys, I purchased my first Mac Pro today, a second hand 2.26GHz 8-core 4,1. Very happy so far I have a Kingston V300 SSD installed in it, using a "MRA260 2.5" to 3.5" drive caddy. Looks like a cheap no-brand model, but it came free with the Mac so I used it. I did a couple of disk benchmarks, and it seems to be maxing out at 150MB/s write, 200MB/s read. The SSD should be performing closer to 450/450MB/s judging by reviews online. Is this a limitation of the Mac Pro, or possibly just a crappy drive caddy? And while we're here, can anyone recommend a decent USB 3.0 PCI card? Thanks in advance.
