CankleMonitor (npub1kd2…lkgn) I am still :ablobcatsweatsip: ing (npub1y6t…9wl9) theprimeape (npub14gg…79df) I’m pretty sure what you’re referring to is SMR (Shingled Magnetic Recording) drives. They work by stacking writes on top of each other slightly offset so you get higher data densities but have the downside of being unable to change things in place; you have to rewrite the entire zone to make changes. They tend to slow down the fuller the drive and don’t handle large continuous writes that well. They’re good for write once ready many but not much else. If you’re buying hard drives for regular use look for PMR or CMR, those are quicker to write but tend to be more expensive per byte.
The reason lots of little files perform badly is that hard drives have a fixed minimal size which tend to be around 4kbs, so any file smaller than that has to round up in the amount of data that needs to be physically read and written. Filesystems also end up fragmented, so a full copy filewise will have the hard drive constantly seeking around to the block of each file.
