Samsung 850 PRO 128GB 2.5" SATA SSD
This drive is a 2.5 inch internal solid state drive with a capacity of 128GB. It uses 3D Vertical NAND memory and a Samsung MEX controller connected through a SATA III interface. The drive delivers sequential read speeds up to 550 MBps and sequential write speeds up to 470 MBps.
Suits SATA 2.5" bays; not for M.2 slots
This drive suits users upgrading a laptop or desktop that accepts a 2.5 inch SATA drive with a 7.00mm height. It supports random read performance up to 100,000 IOPS and random write up to 90,000 IOPS. Buyers needing an M.2 form factor or a different capacity should look at other models.
Deciding spec: 128GB capacity
The 128GB capacity is the single specification that decides whether this is the right part. The drive offers an MTBF of 2,000,000 hours with active power consumption of 2.8W and idle consumption of 0.05W. It operates reliably between 0°C and 70°C with humidity tolerance of 5% to 95% RH.

Domande su questo articolo
Does my laptop need a 2.5 inch SATA drive bay to fit this 128GB SSD?
Yes, the drive uses the 2.5 inch form factor and connects through a standard SATA III port, so the system must provide a matching bay and data cable.
Will this SATA III SSD run at full speed on an older motherboard that only supports SATA II?
The drive is backward compatible with SATA II ports, though sequential reads and writes will be limited to the older interface's lower bandwidth.
How can I confirm the drive is delivering its rated 550 MBps read and 470 MBps write speeds after installation?
Run a benchmark tool such as Samsung Magician or CrystalDiskMark; the sequential results should approach the stated figures when the drive is connected to a native SATA III port.
