Superior transfer speeds
Transcend's M.2 SSD 820S reaches
incredible read and write speeds of up
to 550MB/s and 500MB/s. When used as
a cache, the M.2 SSD 820S provides 1.5
times faster boot time than conventional
hard drives.
Store more in less space
The M.2 form factor enables expansion
and integration of functions onto a
single form factor module solution.
M.2 SSDs include a smaller form factor
but with larger capacities than that of
mSATA and half-slim SSDs.
