While slightly costly, you can buy a 4TB 2.5" SSD in a normal thickness drive. You can not do that with a HDD, the only 4TB 2.5" HDD I am aware of is a 15mm thick one which does not fit in, well, pretty much anything, not laptops, not most bays, nothing, they are only usable as an external drive (but it's useful that way, I have one). I believe this is the first time the capacity crown goes to an SSD at any given time (at least in the consumer space -- in the server space the 16TB 2.5" Samsung SSD and the 60TB 3.5" Seagate are both out of this world but so are their prices too).

I take it you don't deal with enterprise storage then. 15mm is the size of basically every enterprise 2.5" drive sled. That's the form factor of all 10k RPM 2.5" drives. The only thing the drive you described DOESN'T work with are laptops. Pretty much anything else it's a perfect fit.

The laptop drive thickness is the abnormality for the rest of the storage world.

If you go to enterprise storage, then you can get 16TB SSD though. It is not comparable.

What exactly isn't comparable? A 5TB 15mm 2.5" NL-SAS drive is about $250. The "16"TB (it's 15.3TB) SSD you reference is about $10k. The cost per TB of NL-SAS is SIGNIFICANTLY lower, and still absolutely has a place for bulk data storage that doesn't have performance requirements.

Ohhh, I get it, you're now modifying your original post to look like you were aware of enterprise storage. Got it.
