The Western Digital Blue SA510 is a solid-state drive in the 2.5" form factor, launched on May 31st, 2022. It is available in capacities ranging from 250 GB to 1 TB. This page reports specifications for the 1 TB variant. With the rest of the system, the Western Digital Blue SA510 interfaces using a SATA 6 Gbps connection. The SSD controller is the SDC1 (A101-000125) Milpitas from WD, a DRAM cache is not available. Western Digital has installed 112-layer TLC NAND flash on the Blue SA510, the flash chips are made by Kioxia. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The Blue SA510 is rated for sequential read speeds of up to 560 MB/s and 520 MB/s write; random IO reaches 90K IOPS for read and 82K for writes.
At its launch, the SSD was priced at 100 USD. The warranty length is set to five years, which is an excellent warranty period. Western Digital guarantees an endurance rating of 400 TBW, a relatively low value compared to other SSDs.

Notes

Drive:

Possibly Kioxia's BiCS5 Dies

NAND Die:

Although this Die is a 4-plane design, most Kioxia BiCS5 NAND Dies used in most SSDs are dual planes design because of Yield and production cost.
And because of the die being dual-plane the Throughput is cut in half to 66 MB/s per die.
There is no CuA (Circuitry under Array) in the Dual-Plane variant.
Typical Endurance: 1700 ~ 3000 P.E.C.
Typ. Endurance eTLC: 5.000 ~ 7.000 P.E.C.
