Kootion 256GB NVMe M.2 SSD vs SanDisk Ultra Plus 256GB

Buy the Kootion if your machine has an M.2 NVMe slot and you want the fastest boot and app loading. Buy the SanDisk Ultra Plus if you are upgrading an older laptop or desktop with a 2.5-inch SATA bay. The Kootion is roughly five times faster on paper, but it is a budget drive with a Maxio controller and only 45 ratings behind it. The SanDisk is a proven SATA drive with a 3-year warranty and far more owner feedback, though it is slower and heavier.

  • Choose the Kootion if your board has an M.2 2280 PCIe Gen 3 slot and you want quick boots and fast file transfers on a tight budget.
  • Choose the SanDisk Ultra Plus if you have a 2.5-inch SATA bay, want a drive with a long track record and a 3-year limited warranty, and can live with SATA speeds.

What reviewers say

Kootion 256GB NVMe M.2 SSD

  • 4.5 / 545 ratings

Ratings average 4.5 out of 5 from 45 buyers, a small sample. Most report it works as a budget drive that boots and loads faster than the hard drive it replaced.

What people mention
  • SpeedPraisedBuyers say boot times and app loading improve clearly over the hard drive or SATA drive it replaces.
  • InstallPraisedThe 2280 card and included screws make fitting it straightforward for most users.
  • CapacityCriticised256GB is tight once the OS and a few large games are installed.
  • Sustained writesMixedLarge file copies can slow below the rated write speed once the cache is used up.

SanDisk Ultra Plus 256GB

  • 4.8 / 5311 ratings

Owners rate the SanDisk Ultra Plus highly for breathing new life into aging computers. Many note faster boot times and snappier app launches after swapping out a hard drive. A few mention that write speeds drop during large file transfers and that the drive is not the fastest SATA SSD available.

What people mention
  • SpeedPraisedReviewers highlight the big jump in boot and load times compared to hard drives.
  • InstallationPraisedOwners find the 2.5-inch SATA drive easy to install in laptops and desktops.
  • Write speedMixedSome note that write speeds are lower than expected during large transfers.
  • ReliabilityPraised

Questions and answers

Which is faster for everyday use?
The Kootion, by a wide margin. Its NVMe interface moves data several times faster than the SanDisk's SATA link, so Windows boots and large files copy quicker.
Will the Kootion fit my laptop?
Only if the laptop has an M.2 2280 PCIe slot. Many older laptops and most desktops use 2.5-inch SATA bays, where only the SanDisk fits.
Which lasts longer?
The SanDisk has the better paper trail: a 3-year warranty, a 2 million hour MTBF and hundreds of owner ratings. The Kootion rates 200 TBW, which is fine for normal use, but it has little long-term history.
Is the SanDisk worth stepping up to?
Only if you need a SATA drive or want the warranty and proven reliability. If you have an M.2 slot, the Kootion gives far more speed for the same capacity.
Can I use either one in a PS5 or external enclosure?
Neither is a good fit. The PS5 needs a faster Gen 4 NVMe drive, and the SanDisk is an internal 2.5-inch SATA drive, not a portable one.
