Apacer’s ST250-297 utilizes 3D NAND for higher capacity up to 2TB and provides more power efficiency than 2D NAND with compact form factor and great performance. Designed in SATA 6 Gb/s interface, the MO-297 SSD is able to deliver exceptional read/write speed, making it the ideal companion for heavy-loading embedded or server operations with space constraints for host computing systems.

Regarding reliability, ST250-297 is implemented with LDPC (Low Density Parity Check) ECC engine to extend SSD endurance and increase data reliability. In addition, the drive comes with various implementations including power saving modes, global wear leveling, flash block management, S.M.A.R.T., TRIM, power failure management and Hyper Cache technology.

In terms of security, Advanced Encryption Standard (AES) ensures data security and provide users with a peace of mind. Furthermore, with End-to-End Data Protection, data integrity can be assured at multiple points in the path to enable reliable delivery of data transfers.
