The M.2, which is employed in devices such as
smartphones and tablet PCs, is a next-generation
form factor (NGFF
+
) developed by the SATA-IO. It is
more compact and thinner than the conventional
mSATA drive and compatible with interfaces such
as SATA, PCI Express, USB, SD, Display Port, I2C,
and UART. It is now even employed in industrial
equipment and embedded devices. TDK’s SNG4A
series is comprised of SATA 3Gbps M.2s mounted
with TDK SSD controller GBDriver
®
RS4. With an
enhanced ECC function that can extend to
71bit/512byte as well as a read retry function and
auto refresh function, they provide data reliability
that far exceeds that of the existing M.2 specifica-
tion. Also, data security is enforced as it is mounted
with an encryption function AES128bi
