Identity & Definition
This consumer-grade SATA solid-state drive is the Kingston A400 120GB SATA SSD (SA400S37/120G), a refurbished 2.5-inch budget storage device sold by T.E.S IT-SOLUTIONS. The Kingston A400 is a consumer/entry-level SSD designed as a hard drive replacement, using 3D TLC NAND with a Phison S11 DRAMless controller. This is NOT an enterprise SSD — it lacks power-loss protection, end-to-end data path protection, and sustained write consistency. This is NOT an NVMe drive and NOT a SAS drive. Condition: Refurbished — tested and verified by T.E.S IT-SOLUTIONS.
Engineering Context
The Kingston A400 120GB (SA400S37/120G) delivers sequential read throughput up to 500 MB/s and sequential write throughput up to 320 MB/s over its SATA 6Gb/s (SATA III) interface. The drive uses 3D TLC NAND with a Phison S11 DRAMless controller. The DRAMless design means sustained random write performance degrades significantly under heavy loads — acceptable for boot drives and light office workloads but not suitable for continuous writes. Endurance is rated at approximately 40 TBW with a 3-year warranty. The A400 has no power-loss capacitor protection — in-flight writes may be lost during unexpected power events. For enterprise SATA workloads requiring data integrity, the Samsung SM863 or PM883 with capacitor-backed power-loss protection are the appropriate alternatives.
Deployment & Use Cases
The Kingston A400 120GB is deployed as a budget boot/OS drive replacement in workstations and test lab machines where HDD-to-SSD latency improvement is the primary goal. Common deployments include development environment storage where data loss risk during power events is acceptable, non-critical server boot drives where SATA compatibility and low cost are prioritized over enterprise reliability, and desktop/laptop HDD-to-SSD upgrades for general office productivity. The 120GB capacity is strictly for OS and boot purposes.

Compatibility & Hard Constraints
The Kingston A400 SA400S37 uses a standard SATA 6Gb/s connector and fits any 2.5-inch SATA bay or 3.5-inch adapter tray. It does NOT connect to NVMe, SAS, or U.2 slots. The 7mm z-height is standard for consumer and enterprise 2.5-inch trays. The A400 is NOT enterprise-grade — it lacks power-loss protection, and in-flight writes may be lost during unexpected power failures. The DRAMless Phison S11 controller means sustained random write performance is significantly lower than DRAM-cached SSDs. The A400 has approximately 40 TBW endurance and a 3-year warranty — enterprise SSDs at similar capacity offer 10-50x higher endurance. For enterprise SATA needs, the Samsung SM863 or PM883 are the recommended alternatives.
