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


SSD testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise storage media. In today’s testing, we will be evaluating the Sabrent Rocket 4 Plus B47R 4TB  Gen4 NVMe SSD in our Intel Gen 4 Test Bench.  This PC has been optimized to provide the absolute highest performance available using our SSD Optimization Guide.


For this Test Bench, the CPU C-States, Enhanced Intel SpeedStep Technology (EIST) and Intel Speedshift (P-States) have not been disabled. As you will see below, the system is also bumped to 5.3GHz with memory at full speed in its XMP 2 profile.

The components of this Test Bench are detailed below. All hardware is linked for purchase and product sales may be reached by a simple click on the individual item. As well, the title is linked back to the individual build article where performance testing can be validated. Clicking on the Title below will bring you to our complete report on this new Gen 4 PC system.

The software in use for today’s analysis is typical of many of our reviews and consists of Crystal Disk Info, ATTO Disk Benchmark, Crystal Disk Mark, AS SSD, Anvil’s Storage Utilities, AJA, TxBench, PCMark 10, PassMark Performance Test, Final Fantasy XIV Gaming BenchMark, as well as true data testing. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Crystal DiskInfo validates that our SSD is running in PCIe 4.0 x4, using the NVMe 1.4 protocol and confirms that it is TRIM capable.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

ATTO performance hits highs of 6.36GB/s read and 6.64GB/s write which are great, especially with very solid and consistent data throughput progression as sample sizes increased.

  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.
