Toshiba OCZ RD400 PCIe NVMe Solid State Drive Review

Comparison & Final Thoughts
Now the only other NVMe drive that we have tested here at ThinkComputers is the Intel 750 Series 400GB drive. It has rated speeds of 2200 MB/s read and 900 MB/s write. Let’s see how the two drives compare in some of our tests.


As you can see the RD400 beats out the Intel 750 Series in most of the test, this is of course the RD400 has higher rates speeds. Looking at prices it turns out the Intel drive is actually more expensive and offers less capacity (400GB vs. 512GB). If you are looking to choose between the two drives the RD400 is the better choice. Also keep in mind that Toshiba will be selling this drive in M.2 form factor, so if you do have a board that has a fast enough M.2 slot you can save about $40 and just get the M.2 version of the drive.

Traditional SSDs have been hitting their maximum performance for a while now. With that these new PCIe NVMe drives are going to start to take over. The Toshiba OCZ RD400 is a great entry into this new world of SSDs and a solid performer at that. It is one of the fastest solid state drives we have ever tested! On top of that Toshiba really gives you the full package with this drive. You have one of the best SSD warranty and RMA programs out there, the best SSD ultility software we have seen, and of course the PCI-Express adapter board. This allows you to keep your SSD up to date, easily replace it if needed and more.

Right now now 512GB version of the RD400 that we reviewed today is selling at our favorite online retailer for $357.99. Remember it is also available in 128GB, 256MB, and 1TB versions as well. This is a solid state drive that we can definitely recommend and with that we award it our Recommended Award! On top of that we are giving it our Editor’s Choice Award as it is the best solid state drive we have reviewed to date!
