going to smaller (2.5in) diameter helps with spinning faster & faster
access ... the referenced articles says a 60drive, 36terabyte box
delivers 18,000 IOPS ... also mentions that flash/SSD deliver throughput.

i've mentioned before peak z196 I/O benchmark was 2M IOPS using 104
FICON (compared to single FCS announced for e5-2600 claiming over
million IOPS) @18k IOPS/box ... would require 2000 such boxes for peak
z196 I/O benchmark.

following has HDD drive (unit) sales peaked 2010.

has individual drive IOPS
http://en.wikipedia.org/wiki/IOPS

peak individual hard disk 175-210 IOPS

lowend SSD starts at 400 IOPS and goes up to almost 10M IOPS
