Overview
Kingston released the 2.5-inch A400 in 2017 at very competitive prices per GB. It sold in high volume through broad retail distribution, in capacities from 120GB to 1.92TB. It was primarily aimed at consumers and system builders upgrading from hard drives, typically in low-cost desktop and laptop builds.
The A400 is DRAM-less. The controller and NAND have varied between production runs – different batches at the same capacity have used controllers from Silicon Motion and Phison, as well as NAND from multiple suppliers. It probably has more hardware variations than most comparable products sold under a single model name. Performance remains within Kingston's published specs regardless of batch. Being an entry-level model, there's a three-year warranty and TBW is low: 40 at 120GB, 80 at 240GB, 160 at 480GB, 320 at 960GB, and 600 at 1920GB. It also lacks hardware encryption.
The drive also ships in an M.2 SATA (2280) form factor (SA400M8 prefix) with identical specifications.
Reviews

“So, the A400 120 GiB is a great choice if you are looking for an inexpensive SSD to use as a boot drive in a desktop PC or laptop, replacing the UV400 model from the same manufacturer.”
-
“... the A400 series offers more than adequate performance over the SATA interface at a price point that is currently hard to beat.”
