I have 2 Seagate Barracuda ST1000DM003 HDDs in my HPE-130f. How do I tell if they are a .11, .12, or .14 or, if they aren't any of these and what does the .## after the model number mean? They are both 7200 RPM, 64 MB cache, and 6.0Gb/s. One is listed as part # 9YN162-300 1 TB and the other as 9YN162-500 1TB.
They are both working. I hope they stay that way too! I'm just trying to understand the difference, especially when I buy another drive for a new PC that I'm planning on putting together soon. I'd like to get the fastest I can, in my price range. I tried finding out on Seagate's website but couldn't find anything there. I noticed this for the first time when I was reviewing the HDD benchmarks.
