Specifications and features
The sample of ZADAK SSD TWSG4S that has arrived for testing is the 2 TB version of the drive. It is an NVMe 1.4, PCIe 4x4 drive, so you can expect outstanding performance. Unleashed by the PCIe 4.0 ready AMD B550/X570/B650(E) X670(E) chipset and Intel from Z590 (also Z690/Z790), the SSD reaches up to an advertised 7400 MB/sec sequential read – almost fifteen times the performance of many SATA SSDs and seventy times faster than some hard disk drives. The performance stems from the hugely increased bandwidth of PCIe 4.0 (PCI-Express Generation 4), a feature that will be made available to customers for the first time as part of the AMD X570 chipset and 3rd Generation AMD Ryzen Desktop Processors. Easily fitting into a PCIe 4.0 x4 M.2 slot, the NVMe interface has been bumped upwards to the new 1.4 protocol, and high-density TLC NAND combined with a fast controller to enable a new level of single-drive SSD performance. It boasts staggering numbers. The controller is Phison PS5018-E18-41. The series is fitted with 3D TLC (Triple-level cell) NAND flash memory. It allows ZADAK to offer a bigger storage capacity at a lower price. But you’ll see how it will be in reality later in the review.
