Specifications
*
Data retention was measured by assuming that SSD reaches the maximum rated endurance at 40C in power-off state.
•
The endurance of SSD in enterprise application is defined as the maximum number of drive writes per day that can meet the requirements
specified in the JESD218 document of JEDEC standard.
5
Relational formula between DWPD and PBW is below: PBW = DWPD x 365 x 5 x User capacity
6
Random performance was measured by using FIO in Ubuntu with queue depth 32 by 16 workers. Measurements were performed on a
full Logical Block Address (LBA) span of the drive in sustained state. Actual performance may vary depending on use conditions and
environment.
7
Sequential performance was measured by using FIO in Ubuntu with queue depth 32 by 16 worker. Actual performance may vary depending
on use conditions and environment.
8
Typical values.
9
The random read/write latency is measured by using FIO in Ubuntu and 4KB transfer size with queue depth 1 on a random workload
of sustained state.
10
The sequential read/write latency is measured by using FIO in Ubuntu and 4KB transfer size with queue depth 1 on a sequential workload
of sustained state.
11
The maximum taking time to be ready for receiving commands after power-up (CSTS.Ready=1). It is expected that I/O commands may
not be completed at this point.
12
QoS is measured using FIO (99/99.99 %) with queue depth 1 and 128 on 4 KB random and write.
13
QoS is measured as the maximum round-trip time taken for 99 % of commands to host.
14
QoS is measured as the maximum round-trip time taken for 99.99 % of commands to host.
15
IOPS consistency measured using FIO with queue depth 128.
IOPS Consistency (%) = (IOPS in the 99.9% slowest 1-second interval)/(average IOPS during the test).
