Another classic product from SSD market History

The RamSan-630 below (launched in April 2010) was at the time the fastest and highest density SLC flash rackmount SSD.

It was the 6th generation design in this FC-SAN compatible style of enterprise SSD - which is where the numbering in "RamSan-630" came from.

In another article - when the SSD brand sends the wrong signal - I discuss the anomalies which arose from "RamSan" itself over the very long market life of this product.

When IBM acquired TMS and thereby the successors to this product line below - they dropped the RamSan - but kept the numbers and the design the same.
