RN 626 and ST10000vnb004 differences with st10000vn0004

I called Seagate this morning and discussed the question with a knowledgeable support person. I asked them to summarize our conversation in an e-mail so I could provide feedback to the group with regard to these drives. I received the following:

"Thank you for contacting Seagate Support.  As discussed the model number ST10000VN0004 and ST10000VNB004 are Inronwolf 7200, SATA units with a sector size of 512E.  I hope that this information is helpful for you. "

Based upon the verbal discussion these are just a different run number of the drive.

Looking online over the weekend and using the UPC code I found that it may be a case of the Model number and MPN number being different.

Attribute Value

i.e. the Model Number is ST10000VN0004 but the MPN is ST10000VNB004, The ST10000VNB004 number is printed on the outside of the box of the drive (i.e. Seagate's packaging - Without the Ironwolf printed label). I have verified the serial number as a fully waranty part. I suspect that the number printed on the drive itself may be the Model Number instead of the MPN value.

I will update after I get the box open.
