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

CRYSTAL DISK BENCHMARK VER. 4.0.3 X64

Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Crystal Disk Mark also shows similar results to that of ATTO. Reads all reach around 2.6GB/s read and write speed for the 256GB model is over 1.1GB/s while the larger capacities both have over 1.6GB/s write speed. 4K performance is very good with read speeds of about 50MB/s and write speeds around 250MB/s.

AS SSD BENCHMARK VER 1.8

The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

In AS SSD the OCZ RD400s reached overall scores of 2536, 2623, and 2584 points respectively. As normal sequential read and write speeds are a slightly slower than in the other benchmarks with reads coming in at around 2GB/s for the larger capacities, though the 256GB model seems to take the lead here reading at over 2.1GB/s. Writes are also lower in this benchmark with speeds ranging from 900-950MB/s.

AS SSD also gives us a look at IOPS performance. For high QD random reads it was able to deliver performance that exceeds spec. The 256GB model hit 208K IOPS while the 512GB and 1TB models reached over 215K IOPS read. In terms of write, all delivered over 170K IOPS with ease. All copy benchmark results were good with results all under 2 seconds. Again, these speeds are much faster than SATA SSDs.

ANVIL STORAGE UTILITIES PROFESSIONAL

Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.

Finally, similar to that of the other test results, we see very good performance yet again. Overall, the OCZ RD400s reached 10915, 11447, and 11018 points respectively. Sequential performance is around 2GB/s for reads for all capacities and 1GB/s write for the 256GB model and about 1.3GB/s writes for the larger capacities. 4K performance hasn’t varied much from the other tests either.

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.

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.

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?

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 🙂

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).

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?

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.
