M550 mSATA NAND Flash SSD
General Description
General Description
Micron’s solid state drive (SSD) uses a single-chip controller with a SATA interface on
the system side and 8-channels of Micron NAND Flash internally. Packaged in an HDD
replacement enclosure, the SSD integrates easily in existing storage infrastructures.
The SSD is designed to use the SATA interface efficiently during both READs and
WRITEs while delivering bandwidth-focused performance. SSD technology enables en-
hanced boot times, faster application load times, reduced power consumption, and ex-
tended reliability.
The self-encypting drive (SED) features a FIPS-compliant, AES-256 encryption engine,
providing hardware-based, secure data encryption, with no loss of SSD performance.
This SED follows the TCG/Opal specification for trusted peripherals.
When TCG/Opal features are not enabled, the device can perform alternate data en-
cryption by invoking the ATA security command-set encryption features, to provide full-
disk encryption (FDE) managed in the host system BIOS. TCG/Opal and FDE feature
sets cannot be enabled simultaneously.
The data encryption is always running; however, encryption keys are not managed and
the data is not secure until either TCG/Opal or FDE feature sets are enabled.
