Oh sure, and I would stuff storage inside just to avoid extra external connections.

I would pay attention to any trash cans that have the smaller 256GB? SSDs that are only 2 x PCIe 2 lanes not 4 x PCIe 2 lanes. Upgrading to get a bit more capacity *and* performance is a good thing.

The largest replacement SSDs I have noticed for the trash can is 4TB. Including one that OWC used to sell but is no longer available, their replacement generation goes up to 2TB https://eshop.macsales.com/shop/ssd/owc/mac-pro/2013.

A good source of info is https://beetstech.com/blog/apple-pro...pgrades#hdr-15.

It’s embarrassing how bad Apple did with the trash can design. Hanging the SSD off the Intel IO Hub so it is only PCIe 2. Only having one internal SSD slot, closed expansion, weak GPUs, only Thunderbolt 2...so cannot use drives like the Samsung X5 or Sonnet Fusion Thunderbolt 3.

With Mojave especially it’s now extra embarrassing that folks can stuff multiple M.2 NVMe SSDs on PCIe slot adapter cards into a Cheesegrate. Yes they are all PCIe 2 as well. But you get multiple cards at 4 x PCIe 2, if slots are free...
