Our exclusive, innovative firmware technology

Exclusive is our advanced firmware technology; innovations that ensure our SSD solutions continue to deliver maximum hardware performance. Instant Restore solves the customers' concern about SSDs, the read/write efficency in Dirty State. By rearranging the data blocks, garbage collection, and optimization of unused space, the technology allows reading and writing large amounts of data at high speeds. The Global Wear Leveling distributes wear over time, which effectively extends the life of the SSD. At the same time, the Bad Block Management algorithm effectively ensures that data is stored on functional areas of the memory, minimizing the risk of errors.
