This is all well and good, but couldn't just one manufacturer afford to set aside one measly manufacturing line for making 5 1/4 inch Hard Drives again?
Here me out. Now that they are up to 1TB per platter with current tech on 3.5 inch drives just imagine what they could fit into a 5 1/4 inch drive now!!
I know I wouldn't be the only one willing to shell out bux for one of those, providing they used all that space intelligently: With Data Spaces that large it would pretty much be a requirement to include built in internal Mirroring RAID of some sort between the platters, or at least provide the option, for data integrity and protection and longevity of the unit.
I've been salivating over that dream for years now.
