Sabrent Rocket 4TB NVMe SSD Review – TLC Memory Defining Perfomance


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. Check out those IOPS!


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.

    Prices are still ridiculous. For 532 dollars I get the: 4TB small ADATA XPG Spectrix S40G. For the rest of the money you would spend on the Sabrent, you can buy a lot of ice cream.

      This is why I specifically address the fact that the buyer needs to understand his needs with respect to the task at hand. What do you need your SSD to do? Specific to whic SSD, we are late to the game in this review and it has already shown great sales and a great reputation from its purchasers.

      Where are you finding that for $532? Newegg’s price is $799.

    The Sabrent Rocket SDDs will only have the 5 year warranty if you actually register it through their website with proof of purchase receipt from a retailer or online retailer. Register it within the first month because the warranty offered starts on the day of purchase, so they warranty it during period it is being shipped to you from the retailer. I’ve just done the registration the other day so it’s still a fresh memory.

    I just bought the 4 TB off of Newegf it should get here by Monday (August 3rd, 2020)

    I already have the 2TB version of this SSD for my non Steam games. So I’m excited for it to arrive.

    Not a fan of this brand, bought two 1tb M.2 drives and have had nothing but Drive C errors. Sending both back to manufacturer. Horrible, I work from home and the system gets laggy and crashes, after rebooting Event Viewer says repairing Drive C…
