The Netac ZX20 is a solid-state drive in the Unknown form factor, launched in 2022. It is only available in the 1 TB capacity listed on this page. With the rest of the system, the Netac ZX20 interfaces using a Unknown connection. The SSD controller is the SM2320G from Silicon Motion, a DRAM cache is not available. Netac has installed 176-layer TLC NAND flash on the ZX20, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The cache is sized at 90 GB. Copying data out of the SLC cache (folding) completes at 170 MB/s. The ZX20 is rated for sequential read speeds of up to 2,000 MB/s and 1,700 MB/s write.
At its launch, the SSD was priced at 120 USD. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. The TBW rating for the Netac ZX20 1 TB is unknown.
