Silicon Power unveiled its latest PCIe 4.0 SSD, the XPOWER XS70. Designed with hardcore PC and console gamers in mind, this M.2 form factor drive is powered by Phison’s PS5018-E18 controller and is available with up to 4TB of Micron’s 176-layer 3D TLC NAND flash. The XS70 also features a DRAM cache buffer for improved performance as well as support for low density parity check (LDPC) and RAID engine technology for enhanced data integrity and stability. To top it all off, the XS70 is equipped with a unique heatsink that is inspired by the gills of a shark as well as an ultra-fast PCIe Gen4 x4 NVMe 1.4 interface to deliver data transfer rates that are twice as fast as most PCIe 3.0 SSDs.
The XS70 is available in 1TB, 2TB and 4TB capacities. For this review, Silicon Power sent us the 1TB version of the drive which is capable of delivering up to 7,300 MB/s sequential read and 6,800 MB/s sequential write speeds.
