New drive promises better speed, less power use than predecessor

Samsung Electronics today launched the 850 Pro, a new solid state drive (SSD) line-up featuring Samsung's three-dimensional vertical NAND (V-NAND) flash memory technology. The new Samsung 850 Pro, unveiled at the 2014 Samsung SSD Global Summit in Seoul, offers better performance over previous models of Samsung's solid state drives, and will be available globally across 53 markets from this month.

The Samsung 850 Pro uses the SATA III (6Gb per second) interface. Its sequential read performance reaches up to 550 megabytes per second, with write performance of up to 520MB per second. Random read performance is up to 100,000 input/output operations-per-second (IOPS), with write speeds of up to 90,000 IOPS. The drive also offers a Dynamic Thermal Guard feature, which maintains ambient temperature while operating and prevents potential data loss from overheating.

When in deep sleep, the drive consumes only 2 milliwatts of power, a five-fold decrease over previous models. Read and write power have been improved as well, with the drive consuming 3.3W while reading, and 3.0W while writing.

The Samsung 850 PRO will be available in 128GB, 256GB, 512GB and 1TB storage capacities for $130, $200, $400, and $700 respectively. All four of the drives in the line have a 10-year warranty.
