Really now. Last time I cared to look at any of this, it was all 4K blocks.

You are confusing physical blocks (i.e. flash memory) with logical blocks (i.e. filesystems).

Edit: HDDs typically have 4K blocks though ("advanced-format drives"), but we're not talking about HDDs.

Yeah, I honestly have not cared about how hard drives work in about 10 years since I built my last array. I have better things to do with my life than worry about this stuff. I just want to connect a drive, reformat/partition if necessary, and then go back to work. A single SSD now read/writes faster than a 16 drive array (got close in RAID0, but that's just dumb). Now, if SSDs could just get a decent volume size.

They've got what I consider decent size, it's just that the price can be a bit steep compared to an HDD, at least at quantities of 1. $700 will get you an 8TB SSD.

8TB at blazing speeds to boot in a single device. To get decent speeds from HDD would require at least 8 drives striped together. So not only do you need 8+ HDD drives, you also need the enclosure. That would easily double the $700 for the single SSD. Luckily, with USBC/TB4, these enclosures come with the controllers built-in instead of requiring PCIe board
