Samsung 850 Pro SSD with 3D V-NAND Unveiled

By on

Heads up, hardware fanatics. South Korean firm Samsung recently unveiled their latest solid-state drive, the Samsung 850 Pro SSD. What?s different this time? The new drive now comes with the cutting-edge 3D V-NAND technology.

What is 3D V-NAND anyway? Basically, Samsung?s V-NAND stacked 32 flash cells vertically on top of one another in cylindrical rods. Hence, they derived the letter ?V? on V-NAND which means ?vertical?. Compared to the traditional NAND technology where cells are placed together adjacently, you can imagine V-NAND as ?stacks of Pringles cans,? according to a review by Tom?s Hardware. ?Where two cans join vertically, you have a word line. Connect each columnar stack of potato chips together like telephone poles, and you get the bit lines.? As a result, stacking the columns higher minimizes the cell-to-cell interference compared to the horizontal NAND structure.

Samsung claims that their new SSD offers a 20 percent improved power efficiency compared to the 850 Pro and sequential read/write speeds of up to 550 mbps/520 mbps. The 850 Pro is also using a larger 40nm production process, which basically means better performance and more consistency.

The company has given early access of the SSD to several hardware review websites such as Tom?s Hardware and Anand Tech. You can check out their reviews in case you want a more comprehensive and technical understanding.

The Samsung 850 Pro SSD will have a 10-year warranty or 150 TB writes. It will be available in four capacities: 128 GB for $130, 256 GB for $230, 512 GB for 430, and 1GB for $730. That?s a bit pricey even with all the SSDs around. But, of course, good technology always comes at a good price.

Samsung announced that the 850 Pro SSD will be out in the market on July 14, 2014.
