Hi Pat: I just took a peak at your article. It looks good. FYI, I think the following sentence may be inaccurate: "These actual capacities are usually slightly larger than the decimal based number on the box or advertisement." I always heard that the advertisers INTENTIONALLY use the decimal-based number because it comes out slightly larger (i.e. 1TB looks better than 931GiB). From https://en.wikipedia.org/wiki/Hard_disk_drive#Units: -- Software reports hard disk drive or memory capacity in different forms using either decimal or binary prefixes. The Microsoft Windows family of operating systems uses the binary convention when reporting storage capacity, so an HDD offered by its manufacturer as a 1 TB drive is reported by these operating systems as a 931 GB HDD. Mac OS X 10.6 ("Snow Leopard") uses decimal convention when reporting HDD capacity. The default behavior of the df command-line utility on Linux is to report the HDD capacity as a number of 1024-byte units. The difference between the decimal and binary prefix interpretation caused some consumer confusion and led to class action suits against HDD manufacturers. The plaintiffs argued that the use of decimal prefixes effectively misled consumers while the defendants denied any wrongdoing or liability, asserting that their marketing and advertising complied in all respects with the law and that no class member sustained any damages or injuries. -- There is a different issue where you might see that *SSDs* are, in actuality, "slightly larger", but the extra space in that case is not directly accessible by the user. That extra space is really meant to compensate for manufacturing defects. Some of the data "cells" can fail prematurely and, rather than have the drive capacity gradually "shrink" as cells fail, the reserved/hidden cells are substituted in when needed. There is also another hidden memory area in SSDs ( https://en.wikipedia.org/wiki/Host_protected_area) that manufacturers and others use to hide software.
