Much of the ECC versus Non-ECC argument comes down to speed versus reliability. The reliability argument at least is easy to validate, but to settle the question of whether ECC actually lowers system performance, we ran a series of benchmarks with standard RAM, ECC RAM, and Registered ECC RAM that all run at the exact same frequency, timings, and voltage.
I often tell people that SSDs work better with more free space, so anything that increases free space will keep WA lower. The two key ways to expand free space (thereby decreasing WA) are to 1) increase over provisioning and 2) keep more storage space free (if you have TRIM support).
Oracle's Larry Ellison: Data will fly around at 'ungodly speeds' with new in-memory database technology
Engineers at Macronix, one of the world's largest flash memory makers, have reportedly developed a new technology that can extend the life of NAND cells by more than a thousand times by simply applying heat. Most of today's flash modules fail after cells have been programmed...
