Computer Hard-drives: gas-filled and more capacity

The second page of this piece was actually blank, so I back-linked to an earlier piece announcing the original developments. 

Maybe data centers need drives with a capacity of 6 terabytes, but you and I probably don't, unless we never delete anything, and that wouldn't be smart.
Out-of-date programs are too prone to infections from malware, and such-like.

These friction-reducing, cooler-running hard-drives seem interesting, but being the ignoramus that I am, I wonder if this means they will run quieter, and make fewer grunts, groans, and whines as they get loaded up and then unloaded again during peak use cycles. And will Western Digital provide us with updated test procedures, similar to their 'Data Lifeguard Diagnostic for Windows' which tells me that my Western Digital hard-drive is healthy and running normally?
May I digress here a moment? If you diagnose a Western Digital drive with the
Seagate program 'Seatools for Windows' and it fails the Short Drive Self Test or
'SDST', that's probably because it really doesn't work on "many other drives" after all, and you need the one for your own brand, so Google it, please.

The 'SeaTools for Windows' test program still works best on Seagate and Maxtor drives, and while it may give you some results for other brands, it's best to get a test program for your own brand if possible. You don't want to replace a drive just because you used the wrong test program, do you? Of course not!
