Enterprise SSD for tier-zero workloads

The Seagate Pulsar.2 ST800FM0012 is an 800GB 2.5" SAS 6Gb/s enterprise SSD built with MLC memory for price-performance and reliability in performance-hungry applications. It targets environments that demand consistently fast response times and high endurance. Buyers who need higher capacity or a different interface should consider other options.

Sustained write endurance and data integrity

The drive supports up to 10 full drive writes per day for a total bytes written score of 15 petabytes over its life. Max sequential read reaches 370MB/s and write reaches 200MB/s, while 4KB random read hits 48,000 IOPS and random write hits 15,000 IOPS. Advanced media management, background scanning, power-loss data protection and Protection Information maintain integrity under continuous load.

Standard 2.5" SAS installation

The 2.5-inch form factor fits standard SAS drive bays and backplanes using the SAS 6Gb/s interface. Operating temperature ranges from 0°C to 60°C with a shock resistance of 1000G. Idle power draws 4.38W and active power draws 5.93W. Ensure the host system provides SAS connectivity and adequate cooling within the specified temperature range.

Questions about this item

How much power does the ST800FM0012 draw when running continuously in a server?

The drive consumes 5.93 W during active operation and 4.38 W at idle, with an operating temperature range of 0 °C to 60 °C.

What host interface and controller does this SSD require to function?

It needs a SAS 6 Gb/s backplane or HBA; the on-board ASIC controller handles the link and enterprise features such as Protection Information.

Will the 2.5-inch SAS form factor fit alongside older 3.5-inch drives in the same enclosure?

Yes, the 2.5-inch form factor mounts in standard 2.5-inch bays or 3.5-inch adapters, and the SAS 6 Gb/s interface is backward-compatible with 3 Gb/s controllers.
