While these large, multi-controller SSDs were fast compared the SATA based competition, with the introduction of NVMe, they have become a thing of the past. This product line has had a few updates throughout the years with the most recent before the RD400 being the RevoDrive 350.

#OCZ SSD UTILITY NOT RUNNING AT LOGIN SERIES#
In the past OCZ developed the RevoDrive series for those who demanded more performance than what SATA could deliver. Finally, when we put it through the paces for some real world file transfers, it boasted great performance and power efficiency. In PCMark Vantage the RD400 was able to score 245-260K points with many speeds well over 1GB/s and in PCMark 8, it held its own against the fierce competition. Crystal Disk Mark revealed 50MB/s read and 250MB/s write 4K QD1 performance. It was able to achieve over 2.7GB/s read and 1.6GB/s write during ATTO. Looking back at the performance the OCZ RD400 has to offer during our grueling benchmarking sessions, it is without a doubt we can say it is one of the best consumer drives out on the market.

When we first took a look at the OCZ RD400 we noticed right away that it was identical to that of the recently reviewed Toshiba XG3, in fact, we would go as far to say that it is simply a XG3 in disguise! Of course with slight firmware tweaks and an added performance improving driver from OCZ. Digging around in the latest OCZ SSD Utility even somewhat confirms it by showing the the Config ID being XG3_57CZ!
