Samsung 830 Series 128GB SATA SSD

The Samsung 830 Series is a 2.5 inch internal solid state drive with 128GB of MLC flash memory. It connects through a SATA interface and is built for consumer desktops and laptops that need faster boot and load times than a mechanical disk can provide. The drive uses a Samsung controller and is rated for 1.5 million hours MTBF.

Fits 2.5 inch SATA drive bays

The drive fits any 2.5 inch bay that accepts a 0.28 inch high SATA drive. A single SATA data cable and a SATA power connector are all that is required for installation. No additional drivers are needed for Windows 7, Vista, XP, macOS or Linux. The compact form factor frees up space in small chassis and leaves room for extra storage or airflow.

Low power silent operation

With no moving parts the SSD runs completely silent during everyday use. Idle power draw is 0.08W and active power draw is 0.15W, so it adds minimal heat to the system. Operating humidity range is 5 to 95 percent RH. The low thermal output helps keep overall case temperatures down in tight builds.

Questions about this item

What is the 4KB random write IOPS limit that appears first under sustained heavy writes?

The 4KB random write rating is up to 30000 IOPS; sustained workloads will hit this ceiling before sequential throughput.

What are the idle and active power figures when the drive runs all day?

Idle power is .08W and active power is .15W, so heat and fan noise stay minimal during continuous operation.

Which SATA host interface must the system already provide for this 2.5" drive to work?

The drive requires a SATA III port and a standard 2.5" drive bay or adapter in the host system.
