Transcend's SSD452K features the SATA III 6Gb/s interface and state-of-the-art 3D NAND technology, which allows 96 layers of 3D NAND flash chips to be vertically stacked. Compared to 3D NAND at 64 layers, this density breakthrough greatly improves storage efficiency. The SSD452K is built with DRAM cache for fast access, and is fully tested in-house to guarantee reliability in mission-critical applications, boasting an endurance rating of 3K Program/Erase cycles.
Transcend also offers the SSD452K-I with wide temperature (-40? ~ 85?) capabilities to ensure sustained functionality, enhanced endurance and optimal reliability in mission-critical applications.
