KingSpec P3-512 512GB SATA SSD

The KingSpec P3-512 is a 2.5 inch internal solid state drive built for consumer laptops and desktops. It uses 3D NAND flash memory and connects through a standard SATA III 6Gbps interface. The drive suits everyday computing, system upgrades and general storage expansion.

Thermals noise and power

With no moving parts the drive runs silently and produces minimal heat inside a chassis. Idle power draw is rated at .41 watts which helps extend laptop battery life. The solid state design also provides inherent shock resistance for mobile use.

Endurance and speed

The drive offers sequential reads up to 560 MBps and writes up to 530 MBps. Random 4KB performance reaches 65000 IOPS read and 70000 IOPS write. Endurance is rated at 240 terabytes written with an MTBF of 1000000 hours.

Questions about this item

How do I install the 2.5" SATA III drive and which step do people often miss?

Mount the drive in a 2.5" bay, connect the SATA data and power cables, then enable AHCI in the BIOS before installing the operating system; skipping the AHCI step is the common mistake.

What maintenance or replacement will the 512GB P3-512 need later?

The drive has a 240 TBW endurance rating and supports TRIM, garbage collection, wear leveling and S.M.A.R.T. monitoring; no user maintenance is required, and replacement is only needed once the 240 TBW limit is reached.

What limit appears first under sustained heavy writes on this SSD?

The SLC dynamic cache will fill first, after which write speeds drop from the peak 530 MBps toward the native 3D NAND rate; the 240 TBW endurance limit is reached only after very long cumulative use.
