OSCOO ON900T M.2 2230 NVMe SSD — Gen3×4 Speed for Steam Deck, ROG Ally, and Surface

The ON900T packs up to 2TB into the tiny M.2 2230 form factor (30 × 22 × 2 mm) — the size used by the Steam Deck, ASUS ROG Ally, Lenovo Legion Go, and many Microsoft Surface devices. With NVMe PCIe Gen3×4 read speeds up to 3,500 MB/s, it loads games fast while staying cool and power-efficient in handheld thermal envelopes.

Key specifications:

Form factor: M.2 2230 (30 × 22 × 2 mm)
Interface: NVMe PCIe Gen3×4
Read speed up to 3,500 MB/s, write speed up to 3,000 MB/s
Capacities: 512GB / 1TB / 2TB
3D NAND flash
Endurance: 325 / 650 / 1,300 TBW; TRIM, NCQ, and S.M.A.R.T. supported
DRAM-less, low-power design — no heatsink required, just 7.5 g
Operating temperature 0–70°C
Compatible with Windows 10/11, Linux, and SteamOS
3-year warranty

Who it's for: Steam Deck, ROG Ally, and Legion Go owners outgrowing their factory storage; Surface Pro/Laptop users upgrading capacity; mini PCs and thin laptops that only accept 2230 drives.

FAQ:

Does it fit the Steam Deck? Yes — both LCD and OLED models use M.2 2230. You'll need a Phillips screwdriver and about 20 minutes; guides are widely available.
Gen3 or Gen4 — does it matter for handhelds? The Steam Deck's slot runs at PCIe Gen3 speeds, so a Gen3 drive like the ON900T delivers the same real-world performance as pricier Gen4 2230 drives — while typically running cooler and drawing less power.
Will my games and OS transfer? Yes — image your current drive to the ON900T with free tools like Clonezilla, or do a fresh SteamOS install (about 30 minutes).

All OSCOO products come with a 3-year warranty.

Frequently Asked Questions

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

What is M.2 2230 and why is it special?

M.2 2230 refers to the physical size: 22mm wide × 30mm long, making it one of the smallest SSD form factors available. The ON900T is specifically designed for:

Handheld gaming devices: Steam Deck, ASUS ROG Ally, Lenovo Legion Go
Ultra-compact laptops: Microsoft Surface Pro, Surface Laptop Go
Mini PCs and embedded systems: Intel NUC, industrial computers
Drones and IoT devices: Where every gram and millimeter counts

Despite being 44% shorter than a 2242 drive and 73% shorter than a 2280 drive, it delivers the same PCIe 3.0 x4 performance.

Is the ON900T compatible with Steam Deck?

Yes! The ON900T is perfectly compatible with Steam Deck and is one of the most popular upgrades for the device. Here's what you need to know:

Steam Deck Compatibility:

Correct form factor (2230 required)
Single-sided design (required by Steam Deck)
High speeds (3,500/3,000 MB/s) - significantly faster than stock 512GB model
Available up to 2TB capacity

Installation Benefits:

Dramatically reduces game loading times
Allows you to install more AAA games
Faster shader compilation
Improved overall system responsiveness

Can I use the ON900T in devices with 2242 or 2280 M.2 slots?

Yes, but with considerations:

✅ Will Work:

Can be installed in any 2242, 2260, or 2280 M.2 slot
Use the mounting screw at the 30mm position
Functions identically to longer drives

⚠️ Important Notes:

Most motherboards and laptops use 2280 slots - the 2230 will look small but works fine
You may need to verify your motherboard has a 30mm screw hole (most modern ones do)
In desktops/laptops, consider a 2242 or 2280 drive for better value unless space is critical

Best Use Cases for 2230:

Upgrading devices that specifically require 2230
Dual SSD setups where space is limited
Building ultra-compact systems

Can I achieve the advertised 3,500MB/s speeds on any system?

To reach maximum speeds, your system needs:

PCIe 3.0 x4 interface (minimum requirement)
NVMe support in BIOS/UEFI
Sufficient PCIe lanes available
Compatible M.2 slot (Key M or Key B+M)

The drive is also compatible with PCIe 4.0/5.0 systems but will operate at PCIe 3.0 speeds. Most laptops from 2018 onwards support these speeds. Older systems with PCIe 2.0 will still work but at reduced speeds (~1,500MB/s).
