What to know before buying
Listing details to confirm
The listing is inconsistent about the drive dimensions and speed specifications: its title and feature text give M.2 2242 and up to 5400MB/s read and 4900MB/s write, while details also list a 1.65 Inches form factor, 5400 Megabytes Per Second read speed and 4900 MB/s media speed. Treat performance figures as claims and confirm the host supports the M.2 2242 size and PCIe interface before buying. The listed Steam Deck compatibility is also a manufacturer claim, not confirmation for every model or installation.
Who is it for?
A good fit for
- Laptop, mini PC or embedded-system owners seeking a 1TB internal drive, provided the host accepts M.2 2242 PCIe NVMe storage.
- Buyers considering an M.2 storage upgrade for a compatible compact device and who can verify its slot size and interface.
Less suited to
- Systems that require another M.2 length or a different storage interface.
- Buyers who need independently measured speed results or confirmed compatibility with a particular device model.

Customer feedback highlights expected SSD performance, positive impressions of read and write speed, and straightforward installation. One customer also mentions that it runs cool. These reports may be useful for buyers prioritising everyday drive use and installation, but they do not establish measured speeds or compatibility with a particular system. Ratings are mostly five-star, though lower-star ratings are also present, so experiences are not uniformly positive.
Positive themes
- Customer feedback describes expected performance and fast read and write speeds.
- Installation is reported as straightforward.
Frequently asked questions
What size and interface does the OSCOO ON1000B use?
The listing specifies M.2 2242 and PCIe, with PCIe x4 also stated. Check that your device supports this physical size and NVMe interface before ordering.
What read and write speeds are claimed?
The title and feature text claim up to 5400MB/s read and 4900MB/s write. These are listing claims, not independent measurements, and the details present speed information in differing formats.
Is it confirmed to work with every Steam Deck?
No. Steam Deck is named as a compatible console, but the listing does not confirm every model or installation. Check your device’s required SSD dimensions and interface.
