Hardware/Network Transfer Rates

[marklp77]

I was wondering if anyone knew of a resource for
comparing transfer rates (e.g. Ethernet, EIDE, SCSI,
firewire, etc)?

Thanks in advnance,
Mark

This is just as a General frame of reference.

Common Consumer Ethernet, on fast optimized Windows based systems:

Plain Vanilla 100Mb/sec. In the real world 70 to 80Mb/sec.(b=bits 8bits=1Byte)

Wireless* 802.11b = 11Mb/sec. In the real world Usually 4-6Mb/sec.

Wireless* 802.11g = 54Mb/sec. In the real world Usually 18-22Mb/sec.

Wireless* 802.11gsUPER = 108Mb/sec. In the real world Usually 30-38Mb/sec.

*Wireless Ethernet needs additional protocol over head for the transfer. In addition, it is not as stable as Wired so it needs extra processing procedures.


A current popular Hard Drive:

Maxtor DiamondMax Plus 9 (160 GB, ATA-133) . Yields 60MB/sec. (480 Mb/sec.).

I.e. About x7 faster than 100Mb/sec. Ethernet.

A popular SCSI Seagate Cheetah 15K.3 (73 GB Ultra320 SCSI) 76MB/sec.

It sounds like you're trying to compare apples and oranges. Comparing dial-up phone speed to ATA-133 speeds isn't a useful comparison, for instance.

Hmm? if one considers backup options it might be relevant to know in order to figure out timing. Network Backup vs. RAID IDE, RAID SCSI, or simple drive duplication, etc.

BTW. When comparing apples and oranges.

An answer that both are food earns you only One point on IQ Tests.

I guess you were so busy abstracting that you missed my point. It would be helpful to know what use the information would be put to, it would make an intelligent response that much easier...

I was actually thinking of a backup senario, but it's been a courisity of
mine for some time. Based on the specs it looks like firewire and
EIDE transmit at nearly the same speed so that using anything faster
than firewire would be a waste...agreed?

Also, would there be any value in tucking the box with all the backups
in the room next to the server room?

Thanks for taking the time...
