Hi I have a Nimble CS300 which says on the order specs it has 48TB RAW (~ 65TB useable) 3.2TB Cache Dual-Port 10GbE SFP  but when i set it up it says 30.14 TB Usable (43.66 TB Raw) ?

Hi James,

The figures you are comparing are Terabyte (TB) to Tebibyte (TiB) - the former being decimal, the latter being binary. Therefore, 48TB raw equates to 43.66TiB, and 33.13TB usable equates to 30.14 TiB.

TB is typically used in marketing/sales, whereas TiB is what you actually get (ie similar to buying a 1TB drive and it being actually 909GB).

All figures shown within the Nimble GUI are the TiB binary figures.

Hope this helps!

TB is more natural and more universally used by IT, even though "technically" it should be TiB. But that's like only displaying temperatures in Celsius even though pretty much everyone in the US uses Fahrenheit.


How about at least giving us an option to display in TB or TiB.

Indeed, everyone outside of the US uses Celsius.

I'm actually all for the metric system, but "When in Rome"...or the United States, Myanmar, and Liberia.
