SABRENT M.2 NVMe SSD 4TB Gen 4, Internal Solid State 7100MB/s Read, PCIe 4.0 M2 Hard Drive for Gamers, Compatible with PlayStation 5, PS5 Console, PCs, NUC Laptops and Desktops (SB-RKT4P-4TB)

I recently installed an OWC Express 4M2 NVMe Thunderbolt 3 enclosure with four Crucial P3 Plus NVMe SSDs in RAID 0, the performance was nowhere near the advertised speeds of 2800MB/s on my Mac Studio M1 Max, it struggled to achieve 800MB/s read and only 500MB/s write. Turns out the P3 Plus drives use QLC NAND (quad layer), which allows manufacturers to produce large (2TB+) SSDs cheaper than TLC (tri layer) or MLC (multi layer) NAND. The P3s don't have any dedicated DRAM cache, they use part of the drive to cache before the data is written to the disk. This means that the cache is very quickly exhausted, and the write speed drops off even more.Enter the Sabrent Rocket 4 Plus, a PCIe 4 NVMe SSD using TLC technology and a large DRAM cache. With four 2TB drives in software RAID 0 (striped) the performance is excellent, like night and day compared to the Crucial drives. Read speeds actually exceed the stated speed of 2800MB/s (this is a PCIe 3x4 enclosure), and write speeds are a not-too-shabby 2300MB/s using the Amorphous DiskMark, slightly slower using the Blackmagicdesign Disk Speed Test which is more aligned with expected video performance. As I will be using the drive for editing pro video formats this is a better speed indication.The drives seem well made and are supplied in a metal box, a nice touch and feels very premium. By registering them on the Sabrent website you also get a five year warranty which is great. TBW value (Terabytes Written, an indicator of the drive's endurance) is a reasonable 700TB per TB of capacity (compared to just 200 for the Crucial P3 Plus SSDs).Overall these are great drives and work well in TB3 enclosure. On a PCIe 4 motherboard or TB4 enclosure I imagine these will come close to their advertised speeds. I would recommend these for the OWC Express 4M2 enclosure on a Apple Silicon Mac, it's an excellent combination.

Well presented product I must sayWhen you open the outer box you are presented with a copper coloured METAL inside case and that in itself spoke volumes of the care and attention to detail on this product.The drive was easy to install within my ASROCK live Mixer Z790 motherboard and I dare say that I have thoroughly tested this drive and very few nvme products actually live up to their advertises read/write speeds. Well according to Crystal diskmark this does indeed do so and with great gusto.Forget Western Digital 850x as this runs as fast but with a decent reduction in price then Sabrent it seems have built a good name for themselvespros:Well presentedRuns blazingly fastConsthe 4tb version one has to literally pay over three x the cost of thisso may as well get 2x 2tb

Nice and fast

Well worth it, decent capacity, great speed. Running like new.

Great SSD and amazing value for money. So good I had to buy a second one. Very easy to install and fits perfectly.

Great product , quality itemWill buy again

got so hot would have melted enclosure

But works as advertised
