Samsung 840 Series 120GB SATA SSD

The Samsung 840 Series 120GB is a 2.5 inch internal solid state drive built for consumer desktops and laptops. It uses a Samsung MDX controller and a SATA III interface to deliver sequential read speeds of 530 MB/s and write speeds of 130MBps. The drive is suited for everyday computing, operating system installs and general storage upgrades.

Check SATA port and 7mm bay clearance

Verify that your motherboard or laptop provides a free SATA III port and a standard 2.5 inch drive bay with 7.00mm height clearance. The drive draws 0.15W typical power so a regular SATA power connector is sufficient. Confirm the system BIOS recognises SATA SSDs and enable AHCI mode for best performance.

Metal casing with Trim and AES support

The 7.00mm metal enclosure fits tight notebook bays and standard desktop trays without adapters. Built-in Trim support maintains write performance over time while AES hardware encryption secures data at rest. A 1,500,000 hour MTBF rating and 32,000 IOPS random write figure indicate consistent reliability for daily workloads.

Questions about this item

Does the 2.5" SATA III 120GB drive ship with a mounting bracket or cable, or must I buy them separately?

The drive is supplied as the bare 2.5" SATA III unit only; mounting brackets and data cables are not included and must be purchased separately if your chassis or laptop requires them.

The 840 Series lists only a 120GB capacity — is that the sole option for this model?

Yes, the MZ-7TD120BW is offered in a single 120GB capacity; there are no other capacities for this specific model number.

What does the 530 MB/s sequential read figure mean when the drive is installed in a laptop?

The 530 MB/s sequential read is the sustained maximum over the SATA III link; real-world boot and application load times will be lower but still far faster than a mechanical hard drive.
