Small silver 2.5 inch SAS hard drive with label showing 900GB 10000RPM

HP

HP 746843-001 900GB 10000RPM SAS 2.5Inch internal hard drive

SKU CH-K788-NQ40D

A 900 GB SAS internal hard drive spinning at 10000 RPM in a 2.5 inch form factor with SLC NAND flash memory

  • NAND Flash Memory TypeSLC
  • 900 GB capacity stores large datasets
  • 10,000 RPM spindle speed accelerates data access
  • SAS interface connects to enterprise controllers
  • 5 inch form factor fits dense server bays
  • SLC NAND flash memory enhances endurance

HP 900GB 10K SAS Enterprise Drive

This HP 900GB 10000RPM SAS drive uses a 2.5 inch form factor and SLC NAND flash memory. It is built for enterprise servers and storage arrays that require consistent high-speed access. The SAS interface supports dual-port connectivity for redundant paths. Part numbers include 746843-001, 750782-001, and ST900MM0036.

Suited for SAS-Only Bays and Workloads

This drive fits 2.5 inch bays wired for SAS controllers and backplanes. It is not for systems that lack a SAS host bus adapter or compatible backplane. Buyers needing larger capacities or different interface protocols should consider other options. Desktop PCs without enterprise drive support cannot use this unit.

10000RPM Spindle Speed Defines Performance

The 10000RPM rotational speed determines the drive's random I/O latency and sustained transfer rate. This specification is the primary factor for transaction-heavy databases and high-throughput logging. Verify that your controller and cooling can support 10K operation before purchase.

Questions about this item

Does the 900GB SAS drive with SLC NAND require any periodic firmware updates or mechanical servicing during its lifespan?

The drive uses SLC NAND and a 10000RPM mechanical spindle; no user-serviceable parts exist, so only controller firmware updates from the system vendor may be needed.

What is the first performance limit reached when the 10000RPM SAS drive runs sustained write workloads?

The 10000RPM spindle speed and SAS interface set the sustained throughput ceiling before any thermal throttle engages.

How much heat and noise does the 2.5-inch 900GB SAS drive produce when operating continuously in a server chassis?

As a 10000RPM 2.5-inch SAS drive, it generates typical enterprise-grade heat and audible seek noise that standard server airflow is designed to manage.
