[M] Sabrent Rocket 4 Plus NVMe 4.0 Gen4 PCIe M.2 4TB SSD Review
 

The Rocket 4 Plus from Sabrent does offer good performance and quite a bit of capacity when talking about the 4TB SKU, packing the proven Phison PS5018-E18 controller, 2GB of DDR4-2666 DRAM for caching and no less than eight Micron 176-layer 3D NAND TLC ICs. TLCs not only assure a sustained write rate for longer, a higher transfer rate when writing directly to the TLC portion of the chips but are also more durable than QLC, with a rating of 3000TB for the specific 4TB SKU.
