Hard drives have blossomed from 4TB to 6TB, which is a great thing for applications creating an ever increasing amount of data. However, as we've seen more 6TB hard drives come in from vendors, a peculiar problem has arisen. The 6TB hard drives aren't compatible with all of the platforms we test on. They're not compatible for a reason that's unexpected however.

That is true, any more than one is a bonus in my mind, but you know...production users are so finicky, they like to use all four...best practices and all ;)

Small correction to the comment above the first image, stating:

 

 

Specifically at issue are the center screw hole locations, both on the sides of the drives new drive center, and the bottom, which are typically located at the end of the PCB. To illustrate the problem, let's take a look at "normal" side center screw hole locations on a Toshiba HDD located middle of the stack.

 

 

The middle drive is the HGST drive, the Toshiba drive is on the bottom.

How long have 3.5" 1 TB platters been on the market now? I'm surprised drive manufacturers haven't increased platter density at a faster pace. They obviously feel a lot of pressure to come out with higher capacity drives if stuffing six platter into a housing is their only solution.

At least 2 years, probably a bit more. And they're obviously running into physical limitations, otherwise they would have choosen easier ways than 6 platters and 7 platters with Helium. In the mobile space there's at least the 2 TB Spinpoint with 667 GB 2.5" platters, which could be used for ~1.3 TB platters at 3.5" at 5k rpm. Seagate hinted at needing heat assisted magnetic recording for 8 and 10 TB drives, which adds a whole new layer of complexity. Not impossible, but cost per drive is certainly going up.
