SM2250
With the powerful and configurable ECC engine and
The SM2250 SATA SSD Controller is designed with
outstanding performance and a high level of reliability
for a wide range of applications: enterprise server,
workstation system, online storage, notebook, and
desktop. The SSD functions at much faster transfer
speed by saving spin-up and seek time in traditional
HDD and enables a shock-protected and quiet-
operating environment for mobile storage
requirements without any moving mechanical parts.
The SM2250 employees the 8 channel flash interface
with advanced TRIM command, low write
amplification factor, native command queuing, and
global wear leveling to achieve the extremely high
input/output per second (IOPS). From the moment of
boot-up till the system powers off, Silicon Motion ’s
error correcting coding, bad block management and
other proprietary technologies ensure the data
correction and security. With all the featured designs
in hardware and software, the SM2250 can fulfill a
perfect storage system presenting higher
performance and shorter response time for
enterprise-class applications and high capacity
consumer storage.
