ON800 M.2 SATA 2242 SSD

OSCOO ON800 M.2 2242 SATA III SSD — For Laptops and Devices That Need the Short 42mm Form Factor

The ON800 is a SATA III (6Gbps) SSD in the compact M.2 2242 form factor (22 × 42 × 3.5 mm) — built for older laptops, mini PCs, industrial systems, and other devices that only accept 42mm M.2 drives. If your device's manual or current drive says "M.2 2242 SATA," this is the drop-in replacement or upgrade.

Key specifications:

• Form factor: M.2 2242, SATA III (6Gbps) interface — not NVMe/PCIe
• Read speed up to 600 MB/s, write speed up to 500 MB/s
• Capacities: 512GB and 1TB
• 3D TLC NAND flash
• Endurance: 325 TBW (512GB) / 650 TBW (1TB)
• Supports TRIM, NCQ, and S.M.A.R.T. health monitoring
• DRAM-less design, no heatsink required — runs cool in tight spaces, under 10g
• Operating temperature 0–70°C, storage temperature −40–85°C
• Compatible with Windows 10/11 and Linux
• 3-year warranty

Who it's for: Owners of older ThinkPads and compact laptops with 2242-only slots; upgrading a small-capacity factory drive; industrial PCs, POS terminals, and embedded systems that require the short form factor and wide storage-temperature tolerance.

FAQ:

• Will this fit a standard 2280 M.2 slot? Physically yes if your slot has a 42mm mounting point, but check that your device supports SATA M.2 drives — this is not an NVMe drive.
• Is it compatible with Mac? No — supported systems are Windows 10/11 and Linux.
• Does DRAM-less matter? For OS drives and everyday use at these capacities, real-world difference is minimal; you trade a small amount of sustained-write performance for lower power and heat.
