Sabrent Rocket Q NVMe SSD Review – Is 4TB of Data Storage the New Standard?


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 DiskMark results are fairly consistent with ATTO, at least with respect to the high sequential read and writes.


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.The AS SSD results aren’t as appealing as we might like to see but do get a first look at read and write IOPS which appear to be in the general ball park of listed specs.



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.


  1. You have the NAND listed as TLC in the 8th paragraph but, it’s actually QLC. Also, are you still hiring I sent you a couple of emails on January 30th of this year and December 30th of last year. And a tweet.

  2. As these (and all other Rocket Q units) are QLC, and therefore presumably use a TLC/MLC/SLC write cache: do we know at what the write throughput ends up being during periods when that cache is saturated?

    Ive got 4tb samsung QVO SATA drive that i got for £312 black friday deal…
    But i think this is the only consumer 4TB NVMe. Pricey tho

  4. This is the Sabrent Rocket Q with the branding removed. This is the ONLY company in the industry that we know of that actually uses copper branding to help with heat dissipation.

    > Samsung 970 EVO Plus does have this. as far I remeber.
