This user page may meet Wikipedia's criteria for speedy deletion, but no reason has been given for why it qualifies. Please ensure that your reason is based on one of the speedy deletion criteria. Replace this tag with {{db|1=some reason}} .

Please do not edit this page without invitation
I am using this page to develop text, tables, etc., for possible inclusion in articles. It is not my intent to invite a public debate here. If I wanted to do that I would have created a "sandbox" page under the article in question.
- If you would like to pick up an idea here and play with it, everything on WP is free for copying, so by all means, copy it, put it in a sandbox of your own, and have at it.
- If you would like to contribute directly to something here please coordinate with me on my talk page first.
If I create a "sandbox" for a specific project to which I intend and invite others to contribute, it will be on a page of its own, and so annotated.[a] Thank you for your understanding. Jeh (talk) 23:13, 11 April 2011 (UTC)
trial table for binary prefixes article
This table compares, for several different recently popular sizes of hard drives, the notations used by the manufacturers for the advertised capacity vs. the capacity as displayed by various operating systems.
Source | Manufacturers' advertised capacity |
Advertised capacity expressed in bytes |
Microsoft Windows | Actual capacity per Windows display |
Apple Mac OS X 10.6 ("Snow Leopard") and later |
A tiny, tiny minority of software, including some (but not all) utilities under some versions of Linux |
---|---|---|---|---|---|---|
Source is using | SI prefixes | 1 GB = 1000000000 bytes, 1 TB = 1000000000000 bytes |
Customary binary prefixes |
1 GB = 10243 = 1073741824 bytes, 1 TB = 10244 = 1099511627776 bytes |
SI prefixes | IEC binary prefixes |
300 GB | 300000000000 bytes | 279 GB | 279 × 10243 = 299573968896 bytes | 300 GB | 279 GiB | |
500 GB | 500000000000 bytes | 466 GB | 466 × 10243 = 500363689984 bytes | 500 GB | 466 GiB | |
750 GB | 750000000000 bytes | 698 GB | 698 × 10243 = 749471793152 bytes | 750 GB | 698 GiB | |
1 TB | 1000000000000 bytes | 931 GB | 931 × 10243 = 999653638144 bytes | 1 TB | 931 GiB | |
1.5 TB | 1500000000000 bytes | 1.36 TB | 1.36 × 10244 = 1495335813775 bytes | 1.5 TB | 1.36 TiB | |
2 TB | 2000000000000 bytes | 1.82 TB | 1.82 × 10244 = 2001111162552 bytes | 2 TB | 1.82 TiB | |
3 TB | 3000000000000 bytes | 2.72 TB | 2.72 × 10244 = 2990671627551 bytes | 3 TB | 2.72 TiB | |
Notes | Actual capacity is usually slightly higher | Differences between this and advertised capacity are due to rounding errors | Earlier versions of Mac OS used customary binary prefixes |

Notes
- ^ latency = 1/R rotations/minute × 60 seconds/1 minute × 1000 msec/1 second × 1 rotation/2 half-rotations = 30000/R msec/half-rotation
