I’ll just quote from Gary Krakow’s analysis here:
So, when I saw one particular announcement at a show filled with press releases, I got very, very excited: SanDisk Corporation has introduced a 32GB, 1.8-inch solid-state drive (SSD) which is built to be a drop-in replacement for standard mechanical hard disk drives. This means the device has no moving parts.
[…] SanDisk claims a sustained read rate of 62 megabytes per second and a random read rate of 7,000 inputs/outputs per second. In plain English, that means its more than 100 times faster than most current hard disk drives.
Read Gary Krakow’s review, and then put into the context of Alex, Nuno’s and my comments to Alex’s recent MySQL indexing/optimization debate, Nuno Souto’s post on Moore’s law and how it hasn’t applied to disk so far, not to mention my BAHD post and it’s comments and you’ll quickly see why this might be the breakthrough in disk storage that will quickly change the game when it comes to long-term storage performance improvements catching up to CPU and memory improvements.
I also like that it’s only 32GB. :-)
