GIGABYTE today announced the refreshed UD Pro line of high-endurance SATA SSDs. Built in the 2.5-inch form-factor with SATA 6 Gbps interface, the drives come in capacities of 256 GB (GP-UDPRO256G), 512 GB (GP-UDPRO512G), and 1 TB (GP-UDPRO1T). The new drives feature updated 96-layer KIOXIA 3D TLC NAND flash memory, with increased endurance rating across the board. The 1 TB variant offers a staggering 750 TBW endurance (for perspective, the NAS-optimized WD Red SA500 1 TB is rated with 600 TBW); while the 512 GB variant offers 370 TBW; and the 256 GB variant 175 TBW.

All three variants offer sequential transfer speeds of up to 550 MB/s reads, with up to 530 MB/s writes. The 1 TB variant offers up to 98,000 IOPS 4K random reads and up to 89,000 IOPS 4K random writes. The 512 GB model offers 97,000/89,000 IOPS. The 256 GB model offers 98,000/89,000 IOPS. All three drives appear to be using a Phison S10-series controller with fixed 256 MB DRAM cache across all three variants. GIGABYTE is backing these drives with 5-year warranties. The company didn't reveal pricing.
