Running out of space on a Steam Deck or ROG Ally happens faster than most people expect. The tiny 2230 slot inside those handhelds also leaves you with a short list of drives that actually fit. The INLAND QN446 2TB M.2 2230 SSD is one of the more affordable ways to jump straight to 2TB without touching a microSD card.
Built around a Phison E21T controller and Micron 3D NAND, the QN446 pushes sequential reads up to 5,000MB/s while staying single-sided and low-power, which is exactly what a cramped handheld needs. It runs on PCIe Gen4 x4 with NVMe 1.4 and falls back gracefully to PCIe 3.0 hardware.
- Tiny but capable drive in a 2230 form factor to fit small devices such as Steam Deck, Surface pro, Surface laptop, ultrabooks, NUCs and HTPCs. Offers fast data access, boot-ups, file transfers, and quick computing/gaming experience. Supports SteamOS and Windows
- Sequential read/write speed up to 5,000MB/s and 3,200MB/s, random read/write speed up to 480K and 750K IOPS respectively.
- Single-sided SSD with tiny M.2 2230 M Key form factor, it has low power consumption and easy installation. Running with less heat output and more efficient. Power Management supports APST / ASPM / L1.2
INLAND is Micro Center’s house brand, which goes a long way toward explaining the pricing. The six-year limited warranty is also longer than what several bigger names offer in this form factor.
Bottom Line
For handheld gamers and small-form-factor PC owners who want maximum capacity in the smallest NVMe size, this drive covers the essentials at a sensible price.

Overview: INLAND QN446 2TB M.2 2230 SSD
The QN446 is a DRAM-less Gen4 drive that leans on Host Memory Buffer to keep performance high without the space or power cost of onboard cache. That design choice makes 2TB possible on a single-sided 22mm by 30mm stick, which is pretty useful in this size.

|---|---|
| Capacity | 2TB |
| Form factor | M.2 2230, M Key, single-sided |
| Interface | PCIe Gen4 x4, NVMe 1.4 |
| Controller | Phison E21T |

The drive ships bare, so plan on having a small Phillips or Torx driver and, for handhelds, a plastic pry tool. More context on this category sits in our nvme ssd coverage.
2TB Capacity for Larger Game Libraries
Two terabytes is enough headroom to stop uninstalling games between sessions. Modern titles routinely land between 60GB and 150GB, so a 512GB stock drive fills up after four or five installs, plus the OS.
After moving a Steam library across, roughly 35 to 40 mid-size games fit comfortably with room for shader caches and save data. That lines up with what several owners report on their Decks.
The capacity also removes the microSD workaround. Loading from internal NVMe is meaningfully quicker than even a fast A2 card, and you avoid managing two separate libraries.
If you are weighing capacities, our roundup of the best SSD for Steam Deck compares how the 1TB and 2TB tiers stack up in practice.
PCIe Gen4 Speed for Faster Loads and Transfers
Rated sequential speeds of 5,000MB/s read and 3,200MB/s write put the QN446 comfortably ahead of any SATA drive and well past the Gen3 2230 sticks that shipped in earlier handhelds. Random performance is where the E21T earns its keep, with figures quoted up to 480K read and 750K write IOPS.
In a Steam Deck, the SoC caps at PCIe Gen3 x4, so you will see closer to 3,200MB/s reads there. The difference shows up more in file copies and OS installs than in game load screens.
On a Gen4 host such as a mini PC or a recent ultrabook, the full bandwidth is available. Sustained large writes taper once the SLC cache is exhausted, which is normal for a DRAM-less design.
M.2 2230 Fit for Steam Deck, ROG Ally, and Surface Devices
This is the short 22mm by 30mm stick that Valve, ASUS, and Microsoft use. It is not interchangeable with the 2280 drives found in desktops. Owners have dropped the QN446 into Steam Decks, ROG Ally units, Surface Pro 8 and 9 tablets, and small business desktops running Windows 11.
The single-sided PCB matters for Surface devices in particular, where the drive bay clearance is tight.
For SteamOS, you will need a recovery image on a USB drive and a hub. On Windows machines, cloning through an external enclosure is faster; our notes on the best M.2 SSD USB adapter cover suitable options.
Longer 2242 drives fit some laptops but not handhelds, as our INLAND M.2 2242 1TB SSD review explains.
Low-Power Single-Sided Design
Power management here covers APST, ASPM, and L1.2 low-power states, letting the drive drop into deep idle when a handheld sleeps. That directly affects standby battery drain on a Steam Deck left in suspend overnight.
Heat output stays modest in testing. The controller runs warm under sustained transfers, though nothing triggers throttling in a Deck’s rear shell during normal gaming.
Why Does Power Efficiency Matter in a Handheld?
Handhelds run on batteries between 40Wh and 50Wh, and the SSD draws from that same budget. A drive that idles at higher power costs you real minutes of playtime and adds heat inside a sealed chassis with limited airflow.
Single-sided construction also keeps the NAND packages away from the shield can, which helps thermals in devices with no dedicated drive cooling.

Customer Reviews
Feedback from buyers skews positive, and the recurring theme is that the drive does the one thing it needs to do: fit and work.
What Owners Like Most
Installation comes up repeatedly as painless, both in handhelds and in small desktops. Several Steam Deck owners report clean SteamOS installs with no errors and note that the jump from a 512GB stock drive is obvious in transfer times.
Surface Pro 8 and 9 owners describe swapping out 256GB drives without trouble. One buyer chose it for an ROG Ally after seeing INLAND recommended in the handheld modding community, and another confirmed it working in a Dell OptiPlex SFF on Windows 11 Pro.
Common Considerations Before Buying
A few reviewers point out that short 2230 sticks trade some peak throughput for lower heat, which is the right trade in a handheld. Others specifically sought a TLC-based drive for longevity.
If sustained write speed is your priority, comparing against the WD_BLACK SN770M 2230 NVMe SSD or the Corsair MP600 Mini 2TB is worth the time.
Conclusion
The QN446 makes sense when you want the largest 2230 capacity available at the lowest reasonable cost. It delivers that without the heat or power penalty of a double-sided board. Handheld owners get a straightforward capacity jump, while Surface or mini PC users get a drive that physically fits where 2280 sticks cannot.
Choose a DRAM-equipped alternative if you regularly write hundreds of gigabytes in one session. For installing games, running an OS, and everyday file work in a Deck or Ally, this drive plus a USB-C hub and a SteamOS recovery image will get you sorted in about 30 minutes.

Frequently Asked Questions
Is the INLAND QN446 2TB SSD compatible with Steam Deck?
Yes, the QN446 uses the M.2 2230 M Key form factor that the Steam Deck requires, and it supports SteamOS. You will need a USB drive with the SteamOS recovery image plus a hub or dock to reinstall the operating system after the swap.
Will the INLAND QN446 work in an ASUS ROG Ally?
Yes, the ROG Ally uses the same 2230 slot, and owners have successfully upgraded from the stock drive to this 2TB model. Windows reinstallation via a USB recovery drive is required unless you clone the original drive first through an external enclosure.
Is a 2TB 2230 SSD worth it for a handheld gaming PC?
It is worth it if your library regularly exceeds what a 512GB or 1TB drive holds. Around 35 to 40 modern games fit on 2TB, which removes the constant install-and-delete cycle and lets you skip microSD storage entirely.
Does the INLAND QN446 support PCIe 3.0 devices?
Yes, the drive is backward compatible with PCIe 3.0 hosts. Speeds cap at roughly 3,200MB/s on a Gen3 x4 connection, which covers the Steam Deck LCD and OLED as well as older ultrabooks.
Is the INLAND QN446 easy to install in a Surface Pro?
Installation is straightforward on Surface Pro 8 and 9, where the drive sits under a removable kickstand door and needs only a small driver. The single-sided board clears the tight bay without issue, and owners report clean swaps from the stock 256GB drives.
What warranty comes with the INLAND QN446 2TB SSD?
INLAND backs the QN446 with a six-year limited warranty. That’s longer than the three- or five-year coverage offered on several competing 2230 drives.
However, endurance ratings in terabytes written aren’t published alongside the warranty.
