HP DL385 G6 External USB HDD is Extreme Slow the transfer rate will be less then MB,

[Mohammed idris]

We have HP DL385 G6 server with MS Windows 2008 R2 with MS Exchange 2010 to perform the backup into external USB around 40GB is taking whole day, the same I tried into network share is completing in a hours, further the same external USB HDD I tried with another HP DL385 G7 is completing in reasonable time and transfer bit rate more than 8MB,
Note:
Recently I did update smart start 8.6 and Firmware Maintenance 9.2 still the issue remains same.

USB drives can do this with small file transfers. It is USB causing it. I switched to firewire 800 drives at home because of it. On a file server, I would do LTO2 tape drive on SAS controller. You get speed and you can take tapes offsite. External hard drives are good for home backup. I would not use them for production servers. You also get with tape, a rotation. I do Monday to Thursday 2 sets, M1-R1, M2-R2, and Fridays 8 weeks. I remove the first tape each month for archiving.
