Sabrent Rocket 4 Plus SSD With PS5 Heatsink Review – They Switched to B47R Memory Without Telling a Soul!


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 just about the best we have seen with low 4K read random throughput just short of 90MB/s and IOPS just short of that million mark.


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.






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.


The AJA Video Systems Disk Test is relatively new to our testing and tests the transfer speed of video files with different resolutions and Codec.


TxBench is one of our newly discovered benchmarks that we works much the same as Crystal DiskMark, but with several other features. Advanced load benchmarking can be configured, as well as full drive information and data erasing via secure erase, enhanced secure erase, TRIM and overwriting.

  1. Too expensive, too little storage capacity, too slow copying for small files, no PCIe V.5, I hate the SSD manufacturers wholeheartedly for the unnecessary delay of progress. Guys I finally want to take plenty of 100MP photos and 8K120fps videos and be able to save them without having to buy dozens of USB 4 hubs and stack them so that I have enough SSD storage available as a huge heater!

    • Thanks for your reply and I, as well, hope to be reviewing same in PCIe 5.0 soon enough. It is a process and i think that by next year at this time we will be comfortably enjoying 12GB/s and higher. Thank you for taking the time to comment; it is great to hear from readers so far away and you have followed us for some time if I am correct. Danke!

      • The technology of digital cameras, etc. will continue to evolve in the future and more and more data will be generated. For decades, there has been a lack of a solution to satisfy this problem sufficiently and to provide storage space for fast and cheap backup of data. I can only hope that the manufacturers will offer an alternative in the near future, such as a one-time recordable SSD similar to a CD-R. This should offer at least 16TB of storage space at a non-binding price of no more than 32, – € per TB. I will continue to watch the market for the next 3-5 years and if there is still nothing sufficient, then I will have to make my own solution for myself…

  2. I think it’s a great price when comparing to similar products. Just bought the FireCuda 530 4TB for almost 100€ more. Plus there’s an 8TB option from Sabrent, right? Guess endurance is better with Seagate, although I couldn’t find any details on this on their homepage.

    • The Firecuda 530 is a dynamite SSD and any 4TB version is pure gold. I don’t concern myself much with endurance as we have been in the game here since 2007 and I haven’t found any reason to bother myself; these are worlds ahead of hard drives and we might see a fluke once in a blue moon. Another long time poster and thank you.

    • As far as I know, Sabrent’s 8TB SSDs are all QLC-based.

  3. All these reviews keep mentioning the Plextor M10P. But has anyone anywhere in the world actually seen one of these for sale? If I’ll never be able to buy it why should I care?

  4. I was first expecting a shocker, that things went bad!

  5. Thanks for the test, as always those years.

    Yes, there is progress being made in the last 2 years of pcie 4.0 ssd, but this ssd is a somewhat dazzler; they catched up switching the nand, but the small file-test shows the ssd is a dazzler in real world applications. Even with large 4 TB, which should made it write/read pseudo-slc-cache only.
    TBW is standard. Sequential 64k is only good in benchmarks, the IOPS only reached in benchmarks, real world it is halfed.

    Les Tokar, if you finally would start – please! – to switch your ssd tests from 80 % nonsical-the-same-programm-benchmarks, which the developers trim the ssd (to shine in synthetical test), we all could see what the ssds are really about.
    You could start to switch one benchmark at a time 😉

    I find it a waste, that you have such nice writing skills, humor, test methodology, vitamin B (connections), knowledge, but then waste the test product for 80 % the same becnhmark-runs, just to fill pages.

    • Thank you for taking the time to respond and the comps. I hear what you are saying with respect to the type of tests completed but we do seem to get the best return with respect to the way we have our reports put together. Who knows…maybe we will include something a bit different down the road. Thanks again.

  6. Nice stuff, thanks! Can Phison NVMe Flash ID utility report the different NAND type? Have you tried?

    • I can confirm that phison_nvme_flash_id2 detects B47R properly, so you can make it sure without removing any label.
