Specifications & Features
Sabrent is offering three versions of the SSD (1TB, 2TB, and 4TB). For endurance, our tested 1TB model has been rated at 260 TBW. The series will be fitted with QLC written 3D NAND flash memory (vertically stacked). This allows the company to offer Sabrent proper storage volumes.
NAND flash memory (the storage memory used inside an SSD) has become cheaper thanks to the new 64/96-layer fabrication and this year we noticed a move to QLC NAND as well. MLC writes 2 bits per cell, TLC 3 bits per cell, and QLC four bits per cell. You can see both the complication and advantage here, you can store more data in the NAND cells, increasing volume sizes. But you can also see a performance hit with an increasing write bottleneck (which you can buffer with SLC cached, DRAM or Host Memory Buffer on NVMe). Endurance is also a factor, there should be less of it however with modern age wear and care technologies it still is not an issue. Sabrent will offer the series fitted with vertical stacked (3D) NAND, written as QLC, these units receive a proper 5-year warranty.
Phison PS5012-E12 controller
The SSD is making use of a PS5012-E12 controller from Phison. The PS5012-E12 makes use of the NVMe revision 1.3 protocol and as you have been able to notice from the SSD specifications, this controller is very fast across its four PCIs for read and write operations respectively, over an x4 PCIe Gen 3 lane connection that is. Now the shocker, for 4K random read and write operations, the controller is able to perform up to 600,000 operations per second (IOPS) as it (can) makes use of 8 NAND channels. It is compatible with QLC and 96-layer NAND. The controller offers support for up to 8 TB storage as well as offering support for external Thunderbolt 3 SSDs. The PS5012-E12 is available in three versions: the 'normal' PS5012-E12 for high-end SSDs, the PS5012-E12C for mid-range devices, and the PS5012-E12DC for the business market.
