KingSpec P3-8TB 8TB SATA III SSD

The KingSpec P3-8TB is a 2.5 inch internal solid state drive built for consumer laptops and desktops. It provides 8TB of storage using 3D NAND flash memory and connects through a standard SATA III interface.

2.5 inch form factor and SATA III connectors

The drive uses the common 2.5 inch form factor and SATA III connectors, so it fits most laptop bays and desktop drive cages without adapters. Its solid state design has no moving parts, giving it strong shock resistance for portable use. Supported features include TRIM, NCQ, S.M.A.R.T., wear leveling, garbage collection and over-provisioning to maintain consistent operation.

Low power draw and silent operation

With an idle power consumption of 0.25W, the SSD adds minimal load to a system power budget and runs silently. Sequential reads reach up to 550 MBps and writes up to 510 MBps, while 4KB random performance hits 64,000 IOPS read and 40,000 IOPS write. The drive is rated for 3840 TBW and 1,000,000 hours MTBF.

Questions about this item

Will this 8TB drive fit in my laptop's 2.5-inch bay?

Yes. The drive uses the standard 2.5-inch form factor and a SATA III interface, so it fits any laptop or desktop bay designed for a 2.5-inch SATA drive.

What does the 3840 TBW rating mean for daily use?

The 3840 TBW rating means you could write roughly 3 TB every day for the three-year warranty period and still be within the rated endurance.

Does the drive need a heatsink or extra power cable?

No heatsink is included or required; idle power draw is only 0.25 W, and the drive runs from the standard SATA power connector.
