Data sheet | HP Enterprise Solid State Drives
The right SSD for every application
HP Enterprise SSDs are available in four categories based on their endurance: performance,
mainstream, light, and value. The categories indicate the number of drive writes per day
(DWPD
1
) that you can expect from the drive. (DWPD is the maximum number of 4K host writes
to the entire drive capacity of the SSD per day over a five-year period.)

HP Enterprise Performance Solid State Drives
HP Enterprise Performance 12G SAS SSDs provide high performance and endurance. They are
best suited for mission-critical enterprise environments with workloads high in both reads
and writes. These SSDs are available in 800, 400, and 200 gigabyte (GB) capacities. SAS SSDs
transfer data at full duplex allowing greater I/O bandwidth to alleviate bottlenecks. Additionally
SAS uses SCSI commands for error recovery and error reporting, which have more functionality
than the ATA command set used by serial ATA (SATA).
HP Enterprise Mainstream Solid State Drives
HP Enterprise Mainstream 12G SAS and 6G SATA SSDs are best suited for high I/O applications
with workloads balanced between reads and writes. The SAS and SATA SSDs provide the
workload-optimized performance required for demanding I/O-intensive applications. When
paired with HP ProLiant servers, these SSDs help you meet the challenges of Big Data. They
achieve twice the performance and endurance of previous HP SAS and SATA SSDs. The SATA
SSDs come with a six gigabit per second (Gb/s) SATA hot-plug interface and are available in 800,
400, 200, and 100 gigabyte (GB) capacities. The SAS SSDs come with a 12 gigabit per second
(Gb/s) SAS hot-plug interface and are available in 800, 400, and 200 gigabyte capacities.
HP Enterprise Light Solid State Drives
HP Enterprise Light 6G SATA SSDs deliver optimized performance for workloads balanced
between reads and writes. From read caching workloads to Big Data Analytics and more, these
SSDs deliver the performance customers can count on. The 6G SATA SSDs are available in
the 960GB capacity with an endurance of 3.8 drive writes per day (DWPD) over a 5 year life.
HP Enterprise Value Solid State Drives
HP Enterprise Value 12G SAS and 6G SATA SSDs deliver enterprise features for a low price
in HP ProLiant server systems. This entry-level pricing is fueling rapid SSD adoption for
read-intensive workloads because the cost per IOPS compares very favorably to HDDs.
Available capacities for the HP Enterprise Value 12G SAS SSDs are 800GB and 1.6TB. The
6G SATA SSDs are available in 120GB, 240GB, 480GB, 800GB, and 1.6TB capacities.
HP Enterprise Boot SSDs come in capacities of 80GB and 120GB and include an Endurance
Manager feature to dynamically throttle writes, which maintains endurance for boot/
swap applications.
