Performance
Measured performance can vary for a number of reasons. The major factors affecting
drive performance are the density of the drive and the interface of the host. Additional-
ly, overall system performance can affect the measured drive performance. When com-
paring drives, it is recommended that all system variables are the same, and only the
drive being tested varies.
Performance numbers will vary depending on the host system configuration.

Notes:
1. Typical I/O performance numbers as measured using IOMeter with a queue depth of 32
and write cache enabled.
2. IOMeter measurements are performed on an 8GB span.
3. 4k transfers used for READ/WRITE latency values.
4. System variations may affect measured results.
5. Performance numbers are indicative of C400 firmware version 0009 and newer.
Cache Drive Performance
Micron's RealSSD C400 mSATA drive has been tested with Intel
