SSDs driving SATA Express and NVMe innovation

NezSez writes regarding an article in extremetech:

"SATA Express is SATA and PCIe over cables (preserving backwards compatibility) and NVMe is the next improvement of AHCI with much lower latencies by using the PCIe bus/lanes. Both have been developed to improve access to SSD's which have their own processors on-board and can communicate quicker than mechanical drives. The specifications look good (up to 4 times faster and can scale with improvements of PCIe) but analysts suspect it will only be adopted for small form factors.

    "The days of HDD are very much numbered"

    Moore's law applies to memory, CPUs, hard disks, and video file size. Unless you don't store multimedia, I wouldn't count on SSDs surpassing HDDs anywhere soon...

    Indeed, that is why I mentioned the spinning disks will still be used for archival (of multimedia it sounds like for your purposes). Still, I suspect things may very well change in this arena in the next 3 years. Time will tell.

    "Moore's law applies to memory, CPUs, hard disks, and video file size."

    Not any more. I've had 3TB drives for at least a couple of years, and it looks like 5TB has only just been announced, with 4TB the largest that's widely available.
