WD Blue 3D NAND SATA SSD

The WD Blue WDS500G2B0A is a 2.5-inch internal solid-state drive with 500GB capacity. It uses 3D NAND technology and a SATA III interface for consumer desktops and laptops. Sequential reads reach up to 560 MBps and writes up to 530 MBps. The drive is rated for 200 TBW and 1.75M hours MTTF.

Fits 2.5-inch 7mm bays and SATA III ports

This drive installs in standard 2.5-inch drive bays with a 7mm height and connects via a SATA III 6Gb/s port. It requires no additional power cables beyond the SATA power connector. The low active power draw of 52 mW average and idle consumption of 56 mW slumber or 5-7 mW DEVSLP frees up system power budget. WD F.I.T. Lab certification confirms broad compatibility with a wide range of computers.

Sustained workloads within thermal limits

Under sustained load the drive operates within a 0°C to 70°C temperature range. Maximum read power reaches 2,050 mW and maximum write power reaches 3,350 mW. Random performance delivers up to 95,000 IOPS read and 84,000 IOPS write. The 200 TBW endurance rating and 1.75M hours MTTF reflect reliability during continuous operation. Free WD SSD Dashboard software monitors drive health and enables cloning or backup.

Questions about this item

What is the max write power draw when the WDS500G2B0A runs sustained workloads?

The drive can draw up to 3,350 mW during maximum write operations, which is the peak power figure for sustained heavy use.

How much heat and noise should I expect from this 500 GB SATA SSD during all-day operation?

With no moving parts the drive is silent; typical active power averages 52 mW and idle slumber power is only 56 mW, so heat output stays low inside a laptop or desktop.

What existing interface must my system provide for this 2.5-inch WD Blue drive to work?

Your motherboard or laptop needs a standard SATA III 6 Gb/s port and a 2.5-inch 7 mm drive bay or caddy for the drive to connect and function.
