GIGABYTE Announces Updated UD Pro Series High-Endurance SATA SSDs

[btarunr]

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.

It is funny how high endurance drive is now TLC based. Just because they introduced QLC, they automatically upgrade the previous tech as high endurance. Marketing...

"The 1 TB variant offers a staggering 750 TBW endurance "

LOL. 750 P/E Cycles is "staggering"? Just goes to show how much the whole SSD market has been severely dumbed down with QLC:-

"In other words, the V-NAND in 850 Pro is good for 6,000 P/E cycles, which is twice the cycle count of modern 2D MLC NAND but quite far away from Samsung's "ten times the endurance" claims. Either Samsung is using lower binned parts in the 850 Pro (i.e. saving the 30,000 P/E cycle parts for enterprise drives)..."
