I have a Dell T300 Power Edge server with 1 bad SAS drive on a degraded RAID1 array.
Can i replace the SAS drive with a SATA drive?
Thanks

"Rule of thumb is: always replace a RAID drive with the same technology, make and model."
This may be the easiest approach, but as long as you get a disk certified by Dell (Dell co-branded), it will work. Dell drives, regardless of the make/model are loaded with firmware that guarantees it's compatibility with the controller.

A lot of good answers!
Andreas was first, answered my question, and had a very good work-around solution.
David Johnson provided important info about consumer drives, which I didn't know.
I will not plan to use consumer SATA drives for RAID in the future.
PowerEdgeTech brought more important info about Dell controllers and drives.
I prefer to work with Dell computers and this was valuable info to me.

Minor (I hope) mistake in previous comment:
Andreas should have been the "Accepted" solution and the other 2 were the "Assisted" solution.

Just to put this straight.
If you have a SAS Controller it should support SATA devices (its in the Spec)
Can you Mirror (RAID-1) SAS and SATA disks, of course you can! Windows will Mirror them quite happily.
Can you do it on your RAID controller? Probably (see above) but there are always ifs and buts especially without having all the details.

Of course, but the question is not about SAS/SATA physical interoperability.

Of course, but the question was not likely about software RAID.

Not on any hardware RAID controller supported on a PowerEdge T300.

SAS/SATA interoperability, the author actually asks that question.
H/w or s/w RAID, where is the information that says what the author is using
RAID controller, where does it say the author is using a RAID controller?

My mistake for not clarifying - it is a hardware RAID controller.
The Dell T300 series is a mid-to-upper end server.
I don't think one would want to use a software SAS RAID controller on a T300 series.
Question for PowerEdgeTech:
How does the T110 II, with such a good CPU, perform compared to the T310 in a small (<20 PC) network, when the database is fairly small?

@tcexperts77 - thanks, there was quite a good chance you were using a RAID controller, but too many people not reading the questions properly and making too many assumptions
Re controller comparison, that's another question

Rule of thumb is: always replace a RAID drive with the same technology, make and model.
In case that the drive size is not made anymore, then you might change it for a bigger drive ALLWAYS checking that it's supported by the controller, it's not the first time I see a RAID not being rebuilt because nobody checked for the HD's suppor in the first placet.
