The MSA520I features the SATA III 6Gb/s interface and 112-layer 3D NAND flash, delivering density breakthrough that greatly improves storage efficiency. Its built-in DRAM cache allows faster random speeds while the 30µ" gold finger PCB, Corner Bond technology, and anti-sulfur resistor guarantee its reliability in harsh conditions. Transcend also adopts the SLC Mode technology to enable the drive to reach competitive speeds and endurance that are equal to the SLC flash. The MSA520I is fully tested in-house, operating stably in a wide operating temperature range (-40℃~85℃).
