Capacity and interface

This SanDisk Ultra SSD provides 500GB of storage over a SATA III connection. It uses 3D NAND flash and nCache 2.0 technology to accelerate everyday tasks. The drive is built for consumer laptops and desktops that accept a 2.5-inch form factor. It has no moving parts, so it runs silently and resists shock.

Sustained load behaviour

Sequential reads reach up to 560 MBps and writes up to 510 MBps under continuous transfer. The nCache 2.0 layer absorbs bursts before flushing to the 3D NAND array. Lower power draw compared with mechanical disks helps notebook batteries last longer during extended sessions. Performance stays consistent because there are no spinning platters to slow down.

Build and connectors

A standard 2.5-inch SATA connector fits existing drive bays and caddies without adapters. The solid-state construction survives drops that would damage a hard drive. Shock resistance protects data if the system is knocked while running. The SATA interface ensures broad compatibility with older and current motherboards.

Questions about this item

How much power does the 500GB SanDisk Ultra 2.5" SSD draw during all-day operation?

The 3D NAND technology lowers power usage compared to mechanical drives, helping extend notebook battery life during continuous workloads.

Which cable and port must my laptop or desktop already provide for this SATA III drive?

A standard SATA data cable and a matching SATA power connector from the system are required for the 2.5" form factor.

Will the SDSSDH3-500G-G26 work in an older machine that only has a SATA II controller?

The SATA interface is backward compatible, so the drive will function on a SATA II port at that port's speed limit.
