For example, my 1TB SSD includes 1TB (2^30 = 1024^3) bytes of flash but only reports 931GB of available space, sneakily matching the storage industry’s self-serving definition of 1TB (1000^3 = 1 trillion bytes). Great article, but a couple nitpicking corrections (which seem appropriate for a storage article)
Per: https://en.wikipedia.org/wiki/Terabyte - Terabyte is 1000^4, not 1000^3. Also It's been 6+ years since we all agreed that TiB means 2^40 or 1024^4, and TB means 10^12. Indeed, only in the case of memory does "T" ever mean 2^40 anyways. It's always been the case that in both data rates, as well as storage, that T means 10^12. This convention is strong enough that we most of us just have thrown up our hands and agree when referring to DRAM memory, that Terabyte will mean 1024^4, and 1000^4 everywhere else. Indeed, in the rare case where someone uses TiB to refer to a data rate, they are almost without exception incorrectly using it, and, they actually mean TB. |
