Samsung 950 Pro SSD Review – Nvme for the masses?




Tweakers zegt: 7 Conclusion
During a private event in Seoul in his native South Korea in late September, Samsung announced its latest solid state drives. The Samsung 950 Pro was hailed as “marching into the next era ‘and’ sparking new possibilities” thanks to some new techniques that were unified in one drive. Thus, the 950 Pro to the new flagship of the company are.

The drive is equipped with V-nand, formerly “3D V-nand ‘mentioned. That is memory that does not from ‘flat’ transistors is made up, but of vertically oriented transistor tubes, which, moreover, in many layers on top of each other are positioned. In the first version of the 950 Pro will that 32 layers are, for capacities of 256 and 512GB. With the move to V-nand with 48 layers, beginning in 2016, has a capacity of 1TB should also be realized.

To control the V-nand developed a new controller: the UMX controller, with three ARM cores. Two of these are intended for the communication with the nand and the third is for the communication with the host PC. The cores are clocked at 500MHz and the controller has eight channels. There is 512MB of memory lpddr3 present and SSDs devoid up to 6W during activity.

The biggest improvement is the protocol by which the drives are controlled. No longer is that the AHCI protocol that allows SATA drives to date were controlled, but the 950 Pro uses the nvme protocol. This is not the first drive that does that; Intel released a few months ago, the first consumer-nvme drive in the form of the 750 and Samsung had for some time the SM951 drive, although that was primarily intended for OEMs and was not equipped with V-nand. Yet this drive was also sold piecemeal to consumers, but at slightly higher prices. The 950 Pro should be around 200 euros for the 256GB version and 350 euros for the 512GB version.
