500GB SATA III SSD for consumer upgrades

The Samsung 840 Series MZ-7TD500BW is a 2.5-inch internal solid-state drive built for desktop and laptop refreshes. It connects through the SATA interface and delivers 500GB of storage for operating systems, applications and everyday files.

Replaces mechanical hard drives in SATA bays

Moving from a spinning disk to this SSD raises sequential read to 530 MB/s and write to 330 MB/s while random 4K performance reaches 97000 IOPS read and 63000 IOPS write. The jump is worth it when boot times, application launches and file copies feel sluggish on the old drive.

500GB capacity with Trim and AES support

The drive handles typical consumer workloads including OS installs, productivity suites and media libraries. Heavy sustained writes or large game libraries may exhaust the available space. Trim support and AES encryption help maintain performance and protect data over the 1500000-hour MTBF rating.

Questions about this item

Will the 7.00mm height fit my laptop's 2.5" drive bay?

The drive measures 7.00mm tall, which matches the standard slim 2.5" form factor used in most modern laptops and desktops.

What is the correct way to connect the SATA III interface during installation?

Attach both the SATA data cable and the SATA power connector firmly; the step often missed is leaving the power cable loose, which prevents the drive from being detected.

How long before the 500GB 840 Series drive reaches its endurance limit?

The MTBF is rated at 1,500,000 hours, and with AES encryption plus Trim support the NAND cells maintain performance across heavy workloads for years.
