I'm going to get a new 2017 27" iMac soon.

Anyone have any recommendations for an external (2.5") HDD storage shelf? Either a DIY/hack or from a retailer like this one - https://www.amazon.com/Twelve-South-BackPack-Storage-Displays/dp/B00C1C1WU2

I assume a HDD would need to be vertical/horizontal, not velcroed on the back of the stand like an SSD.

There'd be no problem Velcroing it.

The old rule with spinners is to format it in the position you'll be using it in. If upside down, format it upside down, etc.

In practice, it makes little difference. But if you want to be extra cautious, then do it that way.

Drives just need to be relatively stable when in use. Ideally not swinging around or being subjected to unnecessary vibrations like dropping, etc.

It's being bounced around that they don't like. If it's sitting still, it's not particular about its position or angle.

Here's another vote for just using some Velcro to attach it to the back of the stand…

This is a Seagate BackupPlus 4TB RAID0 hard disk simply velcro mounted to the stand. I have it partitioned as a 1TB bootable daily clone of the internal 1TB SSD, and 3TB of storage for music, libraries, documents, etc. which don't need SSD speeds.

It works fine. Doesn't need to be either vertical or horizontal ... otherwise how would they survive in laptop computers!

If you really want a shelf ... check out the TwelveSouth Mac Backpack:
