ON1000X NVMe PCIe Gen4.0x4 M.2 2280 SSD

OSCOO ON1000X M.2 2280 NVMe Gen4 SSD — 7,400MB/s TLC in a Slim, Heatsink-Free Design

The ON1000X delivers near-ceiling Gen4 performance — up to 7,400 MB/s reads — in a bare, single-sided 2 mm design. No bundled heatsink, no thickness compromise: it fits thin laptops and compact builds that flagship drives with pre-installed coolers physically can't, while its efficient TLC design keeps thermals manageable under everyday loads.

Key specifications:

• Form factor: M.2 2280 (80 × 22 × 2 mm), single-sided, no heatsink — maximum device compatibility
• Interface: NVMe PCIe Gen4×4 (backward compatible with Gen3)
• Read speed up to 7,400 MB/s, write speed up to 6,400 MB/s
• Capacities: 512GB / 1TB / 2TB
• 3D TLC NAND flash
• Endurance: 325 TBW (512GB) / 650 TBW (1TB) / 1,300 TBW (2TB); TRIM, NCQ, and S.M.A.R.T. supported
• DRAM-less design — 7.5 g, low power draw suited to laptop batteries
• Operating temperature 0–70°C, storage temperature −40–85°C
• Compatible with Windows 10/11, macOS, and Linux
• 3-year warranty

Who it's for: Thin laptops and handhelds with 2280 slots where a heatsinked drive won't fit; desktop builds where the motherboard's own M.2 shield does the cooling; anyone who wants flagship Gen4 speed and would rather choose their own thermal solution.

ON1000, ON1000X, or ON1000 PRO? Three drives, three jobs. The ON1000 (5,200 MB/s) is the value pick for everyday upgrades. The ON1000X (this drive, 7,400 MB/s) brings flagship speed in the slimmest package — ideal for laptops, or desktops using the motherboard's heatsink. The ON1000 PRO (7,500 MB/s) adds a DRAM cache and pre-installed heatsink — the pick for PS5 out of the box and sustained heavy writes.

FAQ:

• Does it work in a PS5? Yes on speed — 7,400 MB/s clears Sony's 5,500 MB/s recommendation — but the PS5 requires a heatsink, which the ON1000X doesn't include. Add a low-profile M.2 heatsink (a few dollars), or choose the ON1000 PRO, which ships with one pre-installed.
• Will it overheat without a heatsink? For OS, gaming, and typical laptop use, no — modern TLC drives at this class throttle only under long sustained transfers. Most motherboards include M.2 shields, and laptops are designed to cool bare drives. If your workload is hours of continuous writes, the DRAM-equipped ON1000 PRO is the better tool.
• Does it fit thin laptops? That's its specialty — single-sided and 2 mm, it meets the strictest laptop clearance requirements.
