This is a little bit slower drive, but the major difference is the pro version can be encrypted, this one is not!!
Sorry, there was a problem. Please try again later.Other than a hardly noticeable faster rate and different visible look, there’s really not much of a difference concerning any noticeable gains...
Sorry, there was a problem. Please try again later.The sequential read and write speeds will be similar because the interface is limited. SATA III is capable of up to 600 MB/s throughput and both of these drives are using a SATA III interface. Beyond the interface, the drives are very different. Both drives are using V-NAND, but the 850 PRO is using MLC (multi-level cell or 2-bit) while the 860 QVO is using QLC (quad-level cell or 4-bit). The firmware and controllers on each drive are different as well, as a direct result of the switch to QLC on the QVO. Because QLC stores more bits per cell, it's also slower than MLC or even SLC. It might not seem like it on the surface due to the sequential read/write speeds being very similar, but the MLC of the 850 PRO will show speed advantages in the random read/write tests, which is more important for primary OS or frequently accessed drives. The QVO is a solid performer and a big step up over a mechanical HD, but the 850 PRO will have some speed advantages as a result of the underlying tech.
