1.0TB SSD 850 Pro Series

2.5-inch | SATA 6.0Gb/s
The world's first 3D Vertical NAND
Samsung's flash memory is fabricated using an innovative 3D V-NAND architecture, which stacks 32 cell layers on top of one another rather than trying to decrease the cells' length and width to fit today's shrinking form factors. The result is higher density and higher performance using a smaller footprint and a breakthrough in overcoming the density limits of conventional planar NAND architecture.
Shift into high gear with the enhanced RAPID mode
You can kick up the read/write performance on every capacity when you need it with the RAPID mode. Just like shifting gears in a car, Magician software gives you the option to enhance performance by processing data on a system level using free PC memory (DRAM) as a cache, providing 1.8 times faster performance in the RAPID mode.
An SSD that won't quit before you do
With twice the endurance of the previous model, the 850 PRO will keep working as long as you do. Samsung's V-NAND technology is built to handle 150 Terabytes Written (TBW) which equates to a 40 GB daily read/write workload over a 10-year period. Plus, it comes with the industry's top-level ten-year limited warranty.
Work longer with high-efficiency innovation
The efficient, power management components in the 850 PRO enable you work longer and more productively. Boasting the lowest power consumption of any SSD when in full use, the 850 PRO expends less energy while maintaining market-leading performance. The 850 PRO fully supports the sleep mode on the Ultrabook™, consuming only 2 m watts of power. Plus, its LPDDR2 cache memory provides higher performance while consuming 30 percent less power when active and 93 percent less power when idle than typical DDR2 or DDR3 memory.

Rating: 5/5 Samsung SSD November 8, 2016 It used to be the most bang for your buck upgrade you could get for your mac-book was to max out the memory, but not anymore. SSD's have fallen in price to less than $1 a gig and the performance is like WOW! My old mac book boots in less than 25 seconds and apps open up like they were minimized in the task-bar. The price was right, the install was a no brain-er, and the performance is on par with a new mac-book at 1/10th the price. I'm a happy camper.

I would recommend this item to a friend! This review is from 128GB Samsung 850 Pro Series 2.5-inch 7mm SATA 6.0Gb/s Solid-State Drive. Customer Videos:

Rating: 5/5 Rock Solid March 20, 2015 This is the boot drive in my Windows Mac Pro. Everything is lickety split and I've had no problems whatsoever. This drive supposedly has a very long life compared to the 840 so I decided to pay more for my main business computer. Drive failures are not something a business needs.
