Intel Optane Memory M15 - faster than M10
Another news of the Computex conference was the announcement of the next line of caching drives Intel Optane Memory - M15 took the place of the M15 . Compared to its predecessors, the new Optane has become much faster, but the volume has not increased. Under the cut - a comparative plate with the characteristics of the one and the other line.
As already mentioned, the M15 is released in the same volumes as its predecessor - 16, 32 and 64 GB - and the same form factor M.2 2280. But the connection interface has become twice as wide, now it's PCIe NVMe 3.0 x4 that, in fact, made it possible to make such a breakthrough in speed. The table below shows the characteristics of the M15 in comparison with the model of the M10 range.
Drives Intel Optane Memory M15 will be available in the third quarter of this year.
