USB Hard Drive on Server

By McIntyreM ·
What are the drawbacks to adding a USB Hard Drive to a Windows file server? Are there any? I am running out of space quickly and need to add something very soon.

Speed, physical security

by oldbaritone In reply to USB Hard Drive on Server

a SATA-2 drive directly on the system bus has much less overhead than a drive using a USB driver; and I don't believe that a USB drive can use DMA when processing the requests, so an internal drive will probably have a significantly faster access time than a USB drive.

Depending on your installation, there's also the possibility of a physical security issue with a USB drive - it could "just walk away" in the middle of the night perhaps?

Unless your server box is already crammed, why not go to a second drive, or a larger replacement for the current drive? You could use third-party drive management software to copy everything onto the new drive and preserve all of your installed software.

And in addition the the above

Reliability is USB Enclosures have a limited ability to cool the drive and where never designed for Full Time Use. The Drives overheat and fail.

Ideally if you need to use any form of USB Drive for any length of time it needs to be in a Vibrationally Suppressed and Actively Cooled Enclosure which are not cheap. The MX1 from Antec is an ideal case for this but even then I wouldn't be considering running a External Drive 100% of the Up Time of the Server.

You would be better off with some form of Network Attached Storage NAS Enclosure which is a different Kettle of Fish

If there is anything I have learned here

It is this. Thank you, Colin.

I have absolutely no use for the apparatus and procedures thus described, but, I am eternally grateful for having, these many times, learned about them.

Maybe, when I sit nearby the ten-thousand year clock, with a defunct Kindle, I will review these things I have learned from you.
