Intel announces the Optane Memory M15 M.2 cache drives

Intel announced new Optane Memory caching SSDs at Computex. The update from M10, Optane Memory M15, has four PCI Express (PCIe) lanes, two more than its predecessor, which means that it's capable of greater throughput bandwidth. 

The new the Intel Optane Memory M15 drives will not become available in larger volumes sizes. SO that's 16, 32, or 64GB 20nm 3D XPoint flash packing devices. Optane Memory M15 provides the following uplifts compared to the M10 devices. The M15 has an 365 terabytes written (TBW) endurance rating and a five-year warranty, and it supports all of the existing software Intel already has for the M10 series.:

• M15 Sequential Read: up to 2,000MB/s (M10 did up to 1,450MB/s),
• M15 Sequential Write: up to 900MB/s (M10 did up to 640MB/s),
• M15 Random Read (8GB) up to 450k (M10 did up to 250k),
• M15 Random Write (8GB) up to 220k (M10 did up to 140k),

The new units will become available next month.
