480GB SATA SSD for System Refresh

This Kingston SSDNow UV400 drive delivers 480GB of solid-state storage over a SATA III interface. It targets users replacing a mechanical hard drive in a laptop or desktop to gain faster boot and application load times. The Marvell 88SS1074 controller manages TLC NAND for consistent everyday performance. It fits any standard 2.5 inch drive bay or caddy.

Silent Operation Low Power Draw

With no moving parts the drive runs completely silent during typical workloads. Idle power measures 0.672W and average active power is 0.693W, keeping heat output minimal inside compact chassis. Peak write power reaches 2.515W while peak read power stays at 0.590W. The operating range of 0°C to 70°C covers normal indoor environments without additional cooling.

Upgrade From 7200RPM Hard Drive

The UV400 is rated at 10 times the speed of a 7200RPM hard drive, reaching 550 MBps sequential read and 500 MBps sequential write. Random performance hits 90,000 IOPS read and 35,000 IOPS write for snappier multitasking. The jump is worth it when an older system feels sluggish on mechanical storage and a full platform rebuild is not planned. MTBF of 1,000,000 hours signals long service life.

Questions about this item

How do I install this 2.5 inch SATA drive and what step do people miss?

Mount the drive in a 2.5 inch bay, connect the SATA data and power cables, then initialise the disk in your operating system before it will appear.

What maintenance or replacement will this TLC SSD need later?

No mechanical maintenance is required; the drive is rated for 1,000,000 hours MTBF and will only need replacement if the flash wears out after very heavy write workloads.

What limit shows up first under sustained write loads on this 480GB model?

Sequential write speed is capped at up to 500 MBps and random write at up to 35,000 IOPS, so sustained heavy writes will hit those throughput ceilings first.
