1 GBit/s means 1000mbps or 125mbps?
Hi,
Long time no see 
So I was browsing this sweet deal here
https://www.hetzner.com/dedicated-rootserver/ex51-ssd
And it says:
Connection: 1 GBit/s-Port
Guaranteed bandwidth: 1 GBit/s
I am wondering if the bandwidth speed is 1gbps or 10x less??
I am confused by the "Gbit/s" and "gbps"
Comments
It's 1 Gigabit per second = 1GBit/s = 1Gbps = 125MBps = 1000Mbps
Certainly not 1 Gigabyte per second.
Little 'b' is bit, big 'B' is byte. But in hetzner's case since 'Bit' is written out it's kinda self explanatory.
It's 1000Mbps.
Thanks guys... guessed it was too good to be true
Maybe helpful because it's easy to remember: in networking you need 8 b (small 'b', "Bit") for a B (large 'B', "Byte").
But that's theory. Gb/s tells about line speed. What you are interested in however is PAYLOAD which is roughly line speed div 8 minus protocol overhead (headers, etc) minus the fact that networks in the real world are rarely perfect.
So the practical rule of thumb is more like dividing Gb/s (line speed) by 10 to get the number of bytes (payload) that you can actually transfer in real world networks.
Having a 1 Gb/s = 1000 Mb/s line you would typically be able to transfer 1000/10 = 100 MB of payload per second (and even 90 MB/s would be within the normal range to expect).
1 GBit/s= 1 gbps
1 gbps = 0.000909495 Tibit/s
No it's not. 1 Gbps is 1000 Mbps. Nothing tricky. It's a gigabit port.
Always lowercase for the prefix... k, m, g, t, etc.
and then...
8 bits = 1 byte.
"bit" is typically used when describing transfer, e.g. 10 mbps (10 megabits per second).
while "byte" is used when referencing data storage, e.g. 10 mB (10 megabyte).
At least that's what I was taught
no need to guess, https://en.wikipedia.org/wiki/Data-rate_units
Inconsistent use of lowercase and uppercase prefixes on that page
I just saw Chrome downloading page is like 10 MB/s
from what i saw , mostly people uses mbps for bandwidth, network speed , as your description , but people also commonly uses XX KB/s or MB/s to express downloading/uploading speed.
I think this is Chrome (or downloaders in general) trying to make it intelligible for the average user. You're downloading a 100 MB file, so they show MB per second so you don't have to multiply by 8 to understand. Though it should be mB
0,001 Terabit/s
You mean terabits/s right
I guess it's time to review my ancient teaching on metric system abbreviations.
http://www.us-metric.org/si-prefixes-and-their-etymologies/
So not all lowercase. I apologize for the confusion.
No.
Don't burn the server down, 1Gbps is good.
1Byte = 8bits, capitalization matters.
Where, looks pretty consistent to me, correct SI units
I've noticed that usually a hardware speed is almost always by bits while a software based speed is mostly by bytes.
Eg, a file downloads (by software) at 4 MB/s, the hard drive writes at 90 MB/s.
A NIC (hardware) runs at 10Gbe port speed, a PCIe 2.0 x1 link runs at 5Gbps, etc.
My guess of the cause is the overhead between software speed vs hardware speed. Considering TCP/IP protocol, 1Gbe can barely handle 115MB/s due to the overhead. PCIe 2.0 uses 8b/10b encoding so that 5Gbps results in a 500MB/s actual data link.
Yup, I was wrong, as I said. Mea culpa
words of the day. standards. convention. MasonR's original post covers the often encountered confusion, the 2nd post in the thread.
????
I guess he meant that "1GBit/s" (note the large 'B') might mean he's getting a 1 GB/s port rather than a 1 Gb/s one.
Strange anyway because Hetzner did use the capital 'B' but they clearly spoke about
"GBit/s" so there should not be a misunderstanding what they mean.
There's also no such thing as a 1 GB/s (as in gigabyte) port... common sense aids understanding as well.
Absolutely correct. But then, how much would you bet on all customers of [insert any provider] to actually have common sense?
