Industry Leading 3D NAND Flash GIGABYTE UD PRO series SSDs adopt 3D TLC NAND flash, which has higher bit capacity, R/W speed performance, endurance and reliability compared to 2D TLC flash. Moreover, with an optimized controller and firmware, GIGABYTE UD PRO series SSDs provide excellent performance for a smooth PC experience.
External DDR3L SDRAM Cache The UD PRO SSD is equipped with high speed DDR3L SDRAM cache and does not need to reserve over-provisioning space, thus improving the random Read/Write performance. This means the users can use the full capacity of the drive. Moreover, external DRAM can be a buffer between controller and NAND flash for sustained performance when capacity is occupied by more and more data.
