What's the difference between 0G8763 and G8763

Earn,

I am not showing the 0G8763  as being a Dell part number, the G8763 is though. The 0 may be a 3rd party vendors designation.

Zeros are often mistakenly inserted into Dell part numbers because of how the part number is listed on the labels, but it does not belong in the actual part number:

As long as you get "certified" drives and your firmware is up to date, then the make/model doesn't matter since the firmware makes them all work alike.  On-disk cache is not used when attached to a Dell RAID controller that has its own battery-backed cache, so even if there was a difference, it would not be important.

If replacing a 10K drive, 15K will work just fine in its place.

GM250 is cheaper here (and most places I saw):

Of course, this all depends on which controller and system you are using it with.

Wow, thanks for all the great feedback.  I was assuming they were the same but many sites I checked had a listing for each with the G8763 always priced less.

Thanks for the links.  That's cheaper than anything I found.

In a DS/N, the first 2 letters seem to indicate the country of manufacturing, then there's a generic "0". The next 5 characters are the Dell partnumber. Everything after that I'm not sure about (may have a manufacturing date built in or just be a generic serial number).
