It’s similar to the Corsair MP600 GS however is simpler to search out at 2TB and its value is aggressive with different choices. In some circumstances you possibly can go cheaper with QLC or probably pay extra for the better-performing, TLC-based WD Black SN770. The S90 Lite is someplace in-between, however nowhere close to the efficiency or worth of the greatest SSDs available on the market.
Though unexceptional, the S90 Lite does have some quirks. At 2TB it has an overabundance of NAND flash dies which negatively impacts its efficiency, giving the Black SN770 an edge. It additionally has a special pSLC cache response than the MP600 GS which makes it lots much less helpful for sustained workloads, though on the brilliant aspect that forestalls the drive from overheating. Some drives on this class, just like the Silicon Energy UD90 and Group Group MP44L, have swapped to QLC at excessive capability, and that’s additionally attainable for the S90 Lite. Such a configuration can be extra similar to the Solidigm P41 Plus or Essential P3 Plus, so beware.

The Addlink S90 Lite comes within the 512GB, 1TB, 2TB, and 4TB capacities, though the 4TB mannequin appears tough to search out. On the time of evaluation these are on sale for $38.88, $59.88, and $109.99, respectively. That is aggressive with related drives just like the Silicon Energy UD90, the Group Group MP44L, and the WD Black SN770, to call a couple of. Some drives on this class have moved to QLC at 2TB whereas our S90 Lite pattern has TLC, which makes this drive most tasty at that capability.
The S90 Lite is able to as much as 5,000/4,200 MBps for sequential reads and writes, and 780K/800K IOPS for random reads and writes. There isn’t any official TBW however Addlink signifies the guarantee is predicated on “proportion used” by SMART. The guarantee is nice for 5 years.

The 2TB Addlink S90 Lite makes use of a easy, single-sided design. Underneath the fundamental label there’s a controller flanked on all sides by two NAND packages. Putting the controller within the center can present benefits with warmth spreading.
The Phison E21T controller has proven up on lots of nice finances drives. It’s confirmed to be a winner in that regard, providing glorious efficiency for a DRAM-less design. Its major competitors is WD’s proprietary controller within the Black SN770 and, as a substitute with QLC, the Solidigm P41 Plus’s SM2269XT. It’s superb with both TLC or QLC and plenty of fashions include each relying on capability.
The IA8HG94AYA NAND packages are Micron’s 176-Layer TLC, or B47R. Using 4 packages for 2TB of flash implies every bundle is 512GB. As this flash makes use of 64GB dies, every bundle has eight dies in an 8DP configuration. Single-sided drives are best as they’ll slot in a variety of units and could also be simpler to rig for cooling.
