Shuckable Seagate 20TB external hard drive is on sale for $219 — back up your data at 1 cent per GB

Seagate is selling the 24 tb one for $259 and it comes with the full 5 year warranty... So, shuckable for 1.09 cents per GB or 1.08 per full warranty GB.

I guess it is $249, so 1.04, an even better deal...

Yeah, but I switched to Linux in '94 and haven't had to defrag anything since...
Fragmentation isn't an O/S thing, it's a filesystem thing (although the fact that some O/Ses can only use certain filesystems can blur that distinction).

FAT, used in pre-NTFS (which was introduced with WindowsNT and the merged product line of XP) consumer windows is notorious for fragmentation, since it's such a simple filesystem.

Ext2 and 3 are still subject - though far less so than FAT - to fragmentation. As is ext4 and xfs, though again less so than ext2 and ext3 (which means hugely less so than FAT). NTFS is also far less susceptible to fragmentation.

Using Linux to write to a FAT (or exFAT) filesystem - such as on external media or a multi-O/S shared partition - is just as susceptible to fragmentation as writing to it with Windows, or AIX, or MacO/S.

available right now at B&H Photo for $219 instead of its usual $279
This drive is the equivalent of US $372 (18.6 cents per GB) on my local Amazon web site, so I won't be buying one just now.

As a matter of interest, does anyone know if the drive is SMR or CMR? That's always been my concern when shucking 3.5" desktop drives. Will I end up with a decent Enterprise grade CMR, a Commercial grade CMR, or an economical SMR?

I accept SMR has its place reducing the cost-per-GB for rarely accessed archives, but nowadays I stick to CMR-only in desktops and servers.

I find SMR agonisingly slow when the disks become heavily fragmented, plus they're anathema to TrueNAS/FreeNAS resilvering. I prefer to pay more for the extra throughput of CMR.
