OCZ RD400 NVMe SSD Review (256GB/512GB/1TB)


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!

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. It was able to achieve over 2.7GB/s read and 1.6GB/s write during ATTO. Crystal Disk Mark revealed 50MB/s read and 250MB/s write 4K QD1 performance.  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. Finally, when we put it through the paces for some real world file transfers, it boasted great performance and power efficiency.

OCZ RD400 SSD Front Side


In the past OCZ developed the RevoDrive series for those who demanded more performance than what SATA could deliver. This product line has had a few updates throughout the years with the most recent before the RD400 being the RevoDrive 350. 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. It is about time they update the RevoDrive series with some NVMe performance in a much more versatile form factor!

OCZ RD400 SSD M.2 Front Side

A direct competitor to the Samsung 950 Pro and Intel 750 Series the all new RD400 is OCZ’s first consumer M.2 NVMe SSD to enter the market. While this is substantial on its own, what is even more noteworthy is the fact that while other manufacturers state they will have 1TB options in their product line soon, the RD400 is the first consumer M.2 NVMe SSD that is readily available for purchase in 1TB right now! So, if one of you many storage enthusiasts has been waiting for a higher capacity option other than the oh so typical 512GB maximum in a M.2 form factor or want to save some $ in comparison to the Intel 750’s 1.2TB model, order the 1TB RD400 today and be the talk of all your friends!

The OCZ RD400 is so good we just had to give it out Editor’s Choice award!

    One thing I am concerned about with the ocz brand is how reliable they really are vs Intel as had plenty of the ocz die and they didn’t honor warranty.

      I got a bad experience with OCZ product. When you hit the compatible issue with you SSD and reported to their forum. They will direct you to seeking help from notebook maker. They will ban your login ID and deleted your comment status and put you into their future request. Never ever buy this brand. Luckily I got two weeks warranty period with newegg. Ended up I return to newegg and bought new SSD from Samsung without any issue plugged into my rig.

      • blank

        You failed to mention the notebook but, when purchasing that notebook the warranty ONLY applied to the notebook and not OCZ whatsoever. It would be the same as you buying a brand new car and then contacting a spark plug manufacturer with an engine problem for assistance. Maybe I am missing something. What compatibility issue are you speaking of with respect to their SSD? Then again, how were you aware that their SSD was even installed in the product?

        Looks like you are a paid Samsung fanboy. No need to spread advertised lies here.

    • blank

      Yes. Totally agree with your point of view. Make sure you bought from newegg.com which has one or two weeks warranty. If could not use just return for replacement. Their forum is full of complaints. If users having problem with their SSD and submitted request for solution. At first they will try to solve. If got no solution, they will ask you seeking solution from Vendor like HP, Dell and etc. Further follow up, they just put users away by moving user request to future requests and locked down user from giving comment.

    One problem, the highly coveted 1TB model does not appear on that amazon link…plus it’s not up anywhere else. Where I can I order the 1TB RD400?

    • blank

      1TB appears behind the amazon link for me. No one has stock, but they’ll let you order it. I’d call that pretty similar to not being able to order it though 🙂

      • blank

        i see. I was just early…I have a google alert set up for “950 pro 1tb” and when this article first went up, the 1tb was not there…but now it is, but not avail as you said. What’s also a light rub, this price for just the card is $30 more on Amazon and Newegg than the article stated (769 vs the article’s 739).

  3. blank

    I looked into purchasing the competing Intel model, and ended up being discouraged by 1) all the reviews said the excellent benchmark performance made for no perceptible difference in actual consumer workloads as compared to more regular SSDs; and 2) it added a ridiculous delay to system boot times, iirc something like 8-10 seconds. Is this drive any different in those respects?

  4. blank

    One important point, these M2 cards are not compatible with Intel RST raid controllers, I just brought 2 512GB models and found out the hard way. Also had trouble configuring as a Win 8.1 boot drive and gave up (could have been the MSI Z170A Mpower mainboard).No biggie as I wanted them mainly for games so I just use 1 for steam and the other as a video editing scratch drive. They are super fast without the raid zero config, copying between them the write speed topped out at 1.52GBs!

    Last time I was using their new SSD product with HP Elitebook 8570W running Raid 0. It had compatibility issue and pop up blue screen. I logged a report in their Tech Forum. Their forum is full of complaints. If users having problem with their SSD and submitted request for solution. At first they will try to solve. If got no solution, they will ask you seeking solution from Vendor like HP, Dell and etc. Further follow up, they just put users away by moving user request to future requests and locked down user from giving comment. Luckily I got warranty from newegg.com which allow me to swipe with other brand. I later used the Samsung SSD which give me peace of mind. Pls stay away with their product without QC.

    I don’t see any mention of this being Mac compatible. Is this a pure Windows oriented site? Thanks in advance.

    Hi – does anybody know if a samsung 960 pro would work in the add in card that comes with the ocz rd400

    • blank

      If I remember later, I can check for you. There is no reason that it shouldnt work though because the OCZ M.2 SSD is not tied to that board in any way shape or form. The board should work as a typical adapter PCIe for any M.2.

      • blank

        thanks Les for the replay. hopefully you will have good news later.

        the reason i ask the question is that i will be upgrading my pc in oct / nov time frame and until then i want to be able to take advantage of nvme and the only option i have with my current board is to use an AIC card as my board does not have an m.2 slot.

        Hi Les
        Did you get a chance to check this out

      • blank

        My apologies… busy as heck but I just pulled out the device…what drive did you want me to match it with?

      • blank

        i am hoping to get the 2tb samsung 960 pro but i persume that a test with any 960 pro would work

      • blank

        I plugged my main system into the this and we are now running as the Samsung 960 Pro 2TB SSD set on the OCZ RD400 adapter…as the boot drive. No problem whatsoever. My bench is the ASUS ROG Apex Z270.

      • blank

        Thanks Les Great News – so i will buy the cheapest rd400 since you cannot get the adapter on its own, and then just use the adapter for the samsung 960 pro

      • blank

        How does that went for you Flan ? As far as I know, the AIC cards are mere adapters, as the controller is in the SSD itself, but curiously enough, it depends on bios from Z97 or preferible forward Z170 and Z270 is kinda sure to already have native support since earlier bioses.
