SSDs took over the OS-drive and scratch-disk tiers years ago. The conversation has moved on to which tier fits which workload — consumer NVMe for OS, prosumer for content scratch, enterprise NVMe with PLP for database, U.2 for hyperscale, SATA SSDs for laptop refreshes and budget builds.
We supply Samsung, Crucial, Kingston, WD, SanDisk, and Lexar across the consumer-to-enterprise span. The enterprise tier (Kingston DC, Samsung PM9A3, Micron 7450) requires careful matchmaking — power-loss protection, endurance class, and the right firmware revision for the server controller all matter.
