GSA-4163BI vs. GSA-4163B

I’ve been reading a good deal of reviews and am most likely going to pick up a LD GSA-4163B. I normally buy parts from newegg if they have them in stock. They list the drive as a GSA-4163BI.

I was wondering if anyone knew what the I stood for and how it differs from the GSA-4163B drive?


Here is the one I was thinking of. thanks for any thoughts!

They are same.

I would presume the I means Internal drive.

They are all the same drive but the letters on the end designate the color and the type of kit:

4163BI - White (Retail)
4163BB - White (OEM)
4163BK - Black (OEM)
