Gigabyte UD PRO 2.5" 256 GB Serial ATA III 3D TLC

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.
