As with
earlier IBM enterprise SSDs, these solid state drives are designed to
deliver great endurance and reliability. These 4th generation enterprise
class eMLC SSDs were tested to provide 24x7x365 usage running
write-intensive levels for about five years. Actual customer writes will
be much lower, and thus the SSD life span will be much longer. Similar
to the eMLC3 SSDs, the new SSDs provide a Drive Write Per Day (DWPD)
rating of approximately "10", which estimates the number of times the
SSD's capacity could be written per day over the projected life of the
drive. The new eMLC4 SAS SSDs provide significantly improved
price/performance compared to previous eMLC3 SSDs. eMLC4 SSD performance
is improved over previous generations of Power eMLC SSDs. Compared to
the eMLC3 SSDs, the new eMLC4 drives offer improved input/output
operations per second (IOPS), throughput, and latency. For example,
measurements show:
Up to 50% higher maximum IOPS value for random mixed read/write workloads
Up to 750 MBps while reading from the drive or up to 470 MBps while writing to the drive
Up to 20% better latency running a random mixed read/write workload (down to a 0.12 ms latency)
