OWC Mercury Electra 2.5-inch SATA III SSD 7mm Solid-State Drive

Delivery in good time. A day later I ordered the cable to go with it and they both arrived a day later... superb.
Has improved the performance of my MPro so well worth the effort. Apple certainly don’t make it easy for an amateur to change items within the MPro.

250GB OWC Mercury Electra 6Gb/s 2.5-inch SSD Serial-ATA 7mm Solid-State Drive

After reading a number of articles to Speed up my Mac Pro 1.1 it recommended that one should buy a OWC SSD drive Mercury Electra 6G. Really fast drive. I bought one online from Flexx Memory, great value, very fast service ordered the previous morning, came the next day, what a service. I can highly recommend this company and will purchase from them again.
