I have laptop dell 5583 i7 and I want to get m.2 for it and I use it for flutter android studio

which one I choose

kingstone m.2 a400 240gb 500/500 read/write

adata xpg m.2 s11 nvme 240gb 3000/1500 read/write

will I benefit from the highest write/read rate on my laptop?

  • It would be nice to see the prices or price difference for these two SSDs. The ADATA XPG m.2. is faster on paper, but not necessarily better value than the Kingston SSD, possibly not even providing more speed per dollar. I wouldn't be concerned with the read/write speeds as much as the brand, warranty, and life expectancy of the drive.

Those SSDs are NOT comparable.

The first option,

Kingston SSD A400 m.2 240GB

is an mSATA m.2 SSD, the latter


is an NVMe m.2 SSD - using PCIe instead of SATA for the connection.

According to its manual found here, your laptop supports NVMe SSDs.


Go for Adata XPG M.2 S11 NVMe 240GB

This SSD is not only faster also better life which may serve you for long time.
