If they are two different builds, then one is an “A” version, and the other a “B” version, yet, they both are sold as the same version, and they both have same model, barcode, and such?
Correct the drives are different hardware revisions both with the same model number and barcode.
Gee… What an embarassing turn of events!!! I’m finding they work nice in a raid 0, but based upon many 10’s of years of history with working on Raid’s, I cannot condone using two disimelar drives in a Raid…
Functionally there is no difference in the drives and should not be a problem running in RAID.
How about Sandisk exchanging a newer model of the two drives I just purchased and received yesterday (I will supply serial numbers on request) and I will send back the older of the two versions I have, with your direction as to which is which…
This is not a defective drive so this is not something warranty replacement will cover.
