Samsung Unveils SSD 512GB … 100 times smaller than your computer!
The tiny PM971-NVMe is barely bigger than your thumb … but is still capable of hosting more data then a large 2.5-inch SSD!
. The manufacturer Samsung announced the mass production of its new SSD 512GB A priori, the announcement was trivial (Samsung manufactures many SSD) but becomes dramatic when you consider the dimensions of the new model: 20 x 16 x 1.5 mm! The PM971-NVMe is thus smaller than a postage stamp and weighs just 1 gram.
However, it will not be possible to buy it in a computer shop: it is a chip type BGA (Ball Grid Array), to be welded on a map. The prowess of Samsung is to have put into this chip no fewer than 18 components: 16 flash memory circuits 256 Gbits, DDR4 memory cache 4Gb and a control (microprocessor dedicated to the memory management). Note that Samsung uses the third generation of flash memory 3D V-NAND, which has 48 layers of cells.
The Samsung SSD is primarily aimed at ultraportables such as the latest MacBook from Apple. With the protocol NVMe (Non-Volatile Memory Express)), it directly uses the PCI Express channels and not through a SATA interface.
According to the manufacturer, the PM971-NVMe is three times faster than a conventional SSD Sata with flow rates up to 1500 MB / s read and 900MB / s write.Thus, it takes only 3.3 seconds to play high-definition video 5GB and 5.5 s for write. The downside, as the SSD is soldered to the motherboard, it will not be possible to change it if we want such a capacity, or if it fails. Unless the manufacturer provides for a modular concept with the SSD on a daughter card.
Samsung plans to sell its PM971-NVMe customers this month in capacities of 512 GB, 256 GB and 128 GB.
