- Yobibyte (YiB)
- Xennabyte (XB) = 1024 Yottabytes
There is no SI standard for this number. This is one of the proposed continuations set by previous SI standards above, combination of next English alphabet letter X and Greek prefix ennea (9). Also known as:- Xenabyte (XB)
Different spelling (Xena warrior ). - Xenobyte (XB)
Different spelling. - Xonobyte (XB)
Different spelling. - Brontobyte (BB)
It was used by some people to denote anything above Yottabyte, its origin is debated. - Hellabyte (HB)
Proposed by UC Davis student Austin Sendek in 2010. He had run a petition that gathered over 60k supporters. I don't think this will be ever adopted as SI standard, and I'm personally against "hella" prefix, but still mentioning it here as some people use it. - Ronnabyte (RB)
Proposed by Dr. Richard J. C. Brown in 2019.
- Xenabyte (XB)
- Wekabyte (WB) = 1024 Xennabytes
There is no SI standard for this number. This is one of the proposed continuations set by previous SI standards above, combination of next English alphabet letter W and Greek prefix deka (δέκα, 10). Also known as:- Wecabyte (WB)
Different spelling. - Geopbyte (GeB)
Used by the same people that use Brontobyte, and just like it its origin is debated. - Queccabyte (QB)
Proposed by Dr. Richard J. C. Brown in 2019.
This is going to make confusions with quantum units (qbit, qbyte), and it's not like it was proposed long time ago...
- Wecabyte (WB)
- Vendekabyte (VB) = 1024 Wekabytes
There is no SI standard for this number. This is one of the proposed continuations set by previous SI standards above, combination of next English alphabet letter V and Greek prefix hendeka (ἕνδεκα, 11). Also known as:- Vundabyte (VB)
Different spelling. - Vendecabyte (VB)
Different spelling.
- Vundabyte (VB)
Can be confusing...
Basically my stand on it is this -> if you need to denote bytes in both decimal and binary system then use 1KB = 1024 Bytes, 1kB = 1000 Bytes, there simply was no need for this extra "i" to begin with, even their current standard has separation of B = Byte, b = bit, they simply could've standardized upper and lower case for the first letter, it they felt like it was needed for legal disputes.
tl/dr - I just like the old style and don't feel like the "new standard" is in any way better/superior.
