OSCOO ON901 M.2 2280 NVMe Gen3 SSD — 3,500MB/s Everyday Performance, 256GB to 2TB

The ON901 is a PCIe Gen3×4 NVMe SSD in the standard 2280 size — up to 3,500 MB/s, which is the full bandwidth a Gen3 slot can deliver. If your laptop or desktop has a Gen3 M.2 slot (most machines from 2016–2021 do), a pricier Gen4 drive would run at exactly this speed anyway. The ON901 gives that machine its maximum, without paying for headroom it can't use.

3-year warranty

Who it's for: Upgrading 2016–2021 laptops and desktops with Gen3 slots; reviving office PCs and building out fleets (the 256GB option keeps per-seat cost down); budget gaming builds; anyone replacing a failed drive in a Gen3 machine.

Which 2280 drive do I need? Match the drive to your slot. Gen3 slot → the ON901 already saturates it. Gen4 slot → step up to the ON1000 (5,200 MB/s, value), the ON1000X (7,400 MB/s, slim flagship), or the ON1000 PRO (7,500 MB/s with DRAM and heatsink — the PS5 pick). Not sure which slot you have? Check your machine's spec sheet for "PCIe 3.0" or "PCIe 4.0" under storage — or just ask us.

FAQ:

How do I know if my laptop has a Gen3 or Gen4 slot? Machines from 2016–2021 are almost always Gen3; Gen4 arrived with Intel 11th gen and AMD Ryzen 5000 laptops. Your spec sheet or a tool like CrystalDiskInfo on the current drive will confirm.
Is Gen3 still fast enough in 2026? For boot, apps, gaming, and everyday work — yes, comfortably. Real-world responsiveness at Gen3 vs Gen4 is nearly indistinguishable outside large sustained transfers; the slot, not the drive, is the sensible place to save.
Can I put it in a Gen4 slot? Yes — it'll work perfectly at Gen3 speeds. But if your slot is Gen4, consider the ON1000 for more speed at a small step up.

Frequently Asked Questions

This resource is crafted to help you find information easily and efficiently.

Will the ON901 work with my older system?

Yes, the ON901 is compatible with any system that has an M.2 NVMe slot, including older PCIe Gen2 systems from 2015 onwards. While newer systems achieve full 3500MB/s speeds, older systems still see significant improvements over SATA drives.

How does the ON901 compare to SATA SSDs?

The ON901 delivers up to 6x faster sequential speeds than SATA SSDs (3500MB/s vs 550MB/s). You'll notice dramatically faster boot times, application launches, and file transfers. The difference is especially noticeable when working with large files.

Will the ON901 improve my gaming experience?

Yes, you'll experience faster game loading times, reduced texture pop-in, and smoother transitions between game areas. While it won't increase FPS (that depends on GPU/CPU), it eliminates storage bottlenecks that cause stuttering and long load screens.

Can I use the ON901 in my laptop?

Most laptops from 2015 onwards with M.2 slots support the ON901. Check your laptop's specifications for an M.2 2280 NVMe slot. The ON901's energy-efficient design helps preserve battery life compared to older drives.

Do I need a heatsink for the ON901?

The ON901 includes a graphene aluminum heat spreader that handles typical workloads without additional cooling. For sustained heavy use (video editing, large file transfers), your motherboard's M.2 heatsink provides extra thermal headroom.

Why am I not getting 3500MB/s speeds?

Common causes include:

Using a PCIe Gen2 slot (limited to ~2000MB/s)
Outdated chipset drivers or BIOS
Testing with small files (advertised speeds are for large sequential transfers)
Background Windows processes during testing
Drive is nearly full (maintain 10-20% free space)

Can I clone my existing drive to the ON901?

Yes, use free cloning software to transfer your existing OS and data. The ON901 works with standard cloning tools. Ensure the ON901's capacity equals or exceeds your current drive's used space.
