AI Verdict
This 256GB M.2 2230 NVMe SSD is for upgrading storage in compact devices like the Steam Deck, offering PCIe Gen 4 speeds that will adapt to Gen 3 slots.
This 256GB 2230 NVMe SSD is a direct physical fit for devices like the Steam Deck, making it easy to install. Its PCIe Gen 4 interface will operate at Gen 3 speeds in compatible slots, providing a performance upgrade over eMMC storage. However, the 256GB capacity is quite limited for modern gaming, making it a temporary solution or only suitable for very light users.
If 256GB isn't enough, look for a 2230 NVMe SSD with 512GB or 1TB capacity to avoid running out of space quickly.

Pros
- Single-sided 2230 form factor fits compact devices like the Steam Deck without modification.
- Utilizes newer Kioxia BiCS5 112L TLC NAND flash, offering better performance than older SN530 drives.
- PCIe Gen 4x4 interface provides higher theoretical speeds, even if limited by Gen 3 host devices.
- Users report it working without issues in Steam Deck for months, even with demanding games.
- Comes with a 2-Year Oemgenuine Warranty, providing some coverage for an OEM part.
Cons
- 256GB capacity is small for modern gaming or extensive data storage needs.
- Higher power consumption and temperatures under load compared to some alternatives, potentially impacting battery life in portable devices.
- Bulk packaging means no screws, cables, or adapters are included, requiring separate purchases.
- As an OEM drive, it lacks a direct manufacturer warranty, relying solely on the reseller's 2-year offering.
Dimension Scores
As a PCIe Gen 4x4 NVMe drive, it offers faster theoretical speeds than Gen 3 drives, even if limited by host device's Gen 3 slot, and is superior to eMMC storage.
Users report months of use in Steam Decks without issues, suggesting adequate operational stability, but as an OEM drive, long-term manufacturer support is absent.
256GB is a minimal capacity for modern gaming or general use, quickly becoming insufficient after installing a few large titles.
The 2230 M.2 form factor and NVMe interface make it highly compatible with many compact laptops, desktops, and portable gaming devices like the Steam Deck.
Best For
- Upgrading the internal storage of a 64GB Steam Deck for more game installs.
- Replacing a failing 2230 SSD in a compatible laptop or desktop.
- Users who prioritize a single-sided 2230 form factor for device compatibility.
Not Recommended For
- Anyone needing significant storage for a large game library or extensive media files.
- Users prioritizing maximum battery life in portable devices due to its higher power draw.
- Those who prefer retail-packaged drives with full manufacturer support and included accessories.
Watch Out For
- The 256GB capacity fills up quickly; some users find even 512GB too small for a Steam Deck after installing a few AAA titles.
- Higher power consumption (rated up to 6.3W peak) can lead to reduced battery life in portable devices compared to lower-power alternatives.
- Bulk packaging means you'll need to source your own tiny M.2 screw and potentially a spudger for installation, which are not included.
- Some users on Reddit expressed concern about the 2.5A current draw potentially causing issues, though others reported no problems over months of use.

What Buyers Say
This 256GB WD SN740 is a popular choice for upgrading portable gaming devices, primarily because its 2230 form factor fits perfectly and it's a single-sided drive, which is a must for many compact systems. While it's a PCIe Gen 4 drive, users confirm it works well in Gen 3 slots like the Steam Deck, providing a noticeable speed bump over slower eMMC storage. However, the 256GB capacity is frequently cited as a limitation, filling up rapidly with just a few games. There are also some discussions around its higher power consumption compared to stock drives, though many users haven't reported significant battery life issues.
“Needed more space for my Steam Deck, this 256GB SN740 fit right in, but man, 256GB disappears fast when you're downloading games, should've gone bigger.”
Common Praise
- Fits perfectly in Steam Deck and other 2230 slots due to its single-sided design.
- Provides a noticeable speed increase for loading games and applications compared to eMMC storage.
- Works reliably for months in portable gaming devices without reported failures.
- Easy installation process for those familiar with device disassembly.
Common Complaints
- 256GB capacity is too small, quickly running out of space after installing a few games.
- Higher power draw (up to 6.3W peak) compared to stock SSDs, raising concerns about battery life.
- Bulk packaging means no included screws or tools, requiring separate purchases.
- Being an OEM drive, it lacks a direct manufacturer warranty, relying on the reseller's coverage.
Ownership Tips
- Even though it's Gen 4, it runs fine in Gen 3 slots, but you won't get full Gen 4 speeds.
- You absolutely need a tiny M.2 screw and a spudger for installation, they're not in the box.
- The drive can get warm during heavy use, but it hasn't caused throttling in my Steam Deck.
- 256GB is barely enough for a few big games; plan on offloading or using a microSD card a lot.
Frequently Asked Questions
Is this SSD compatible with the Steam Deck?
Yes, this is a 2230 M.2 NVMe SSD, which is the correct form factor and interface for the Steam Deck. It's a popular choice for upgrades.
Will this SSD improve performance on my Steam Deck?
If you're upgrading from a 64GB eMMC model, you'll see a significant speed improvement. While it's a Gen 4 drive, it will run at Gen 3 speeds in the Steam Deck's Gen 3 slot.
Does this come with installation tools or screws?
No, this product comes in bulk packaging and only includes the drive itself. You'll need to provide your own M.2 screw and any necessary opening tools.
What about battery life with this drive in a portable device?
The SN740 has higher power consumption than some stock drives. While some users report no noticeable difference, Tom's Hardware noted higher power draw under load, though power-saving features mitigated battery life impact in their Steam Deck tests.
Is this a single-sided SSD?
Yes, the WD SN740 is a single-sided M.2 2230 SSD, which is crucial for fitting into many compact devices like the Steam Deck.
Buying Guide
When you're looking at M.2 SSDs, especially for compact devices, the '2230' part is super important – it's the physical size (22mm wide, 30mm long). You need to make sure your device has a slot that can physically fit this size. Also, 'NVMe' means it's using a fast interface, but the 'PCIe Gen' number tells you its maximum speed potential. If your device has a Gen 3 slot, a Gen 4 drive will still work, but it'll run at Gen 3 speeds, so don't expect miracles.
Capacity (256GB)
This is how much data you can store, like the size of a bucket. 256GB is a small bucket; it fills up fast with modern games or large files, so consider your needs carefully.
Form Factor (2230 Millimeters)
This is the physical size of the drive. Think of it like a specific key for a lock – if your device needs a 2230 key, only a 2230 drive will physically fit into the slot.
Interface (NVMe)
This is the communication language the drive uses to talk to your computer. NVMe is like a super-fast express lane compared to older SATA drives, meaning quicker loading times and snappier performance.
Alternatives
If 256GB isn't enough, look for 2230 NVMe SSDs with 512GB or 1TB capacities. If battery life is a top concern, research drives known for lower power consumption in the 2230 form factor.
