Performance

Measured performance can vary for a number of reasons. The major factors affecting

drive performance are the capacity of the drive and the interface of the host. Addition-

ally, overall system performance can affect the measured drive performance. When

comparing 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.

For SSDs designed for the client computing market, Micron specifies performance in

fresh-out-of-box (FOB) state. Data throughput measured in "steady state" may be lower

than FOB state, depending on the nature of the data workload.

For a description of these performance states and of Micron's best practices for per-

formance measurement, refer to Micron's technical marketing brief Best Practices for

SSD Performance Measurement.

Notes:

1. Performance numbers are maximum values, except as noted.

2. Typical I/O performance numbers as measured using Iometer with a queue depth of 32

and write cache enabled. Fresh-out-of-box (FOB) state is assumed. For performance

measurement purposes, the SSD may be restored to FOB state using the SECURE ERASE

command.

3. Iometer measurements are performed on an 20GB span of logical block addresses

(LBAs).

4. 4KB transfers with a queue depth of 1 are used to measure READ/WRITE latency values

with write cache enabled.

5. System variations will affect measured results. For comparison, PCMark scores are meas-

ured with the SSD as a secondary drive in a two-drive system. When measured as an OS

drive, system overhead can cause lower scores.
