Why Disks Speeds aren’t Increasing

Why Disks Speeds aren’t Increasing

When you look at disk transfer rates, it’s pretty obvious that the faster you spin them, the lower the rotational latency and the better the transfer rates. It’s also very clear that disk transfer rates are improving much slower than memory subsystem bandwidth. Why not rotate disks faster? We’ve had 15,000 RPM enterprise disk for…
