Amazon is flagging 23 offers on this selection right now. The cheapest new price per TB on this page is £25.83/TB, on the WD 24TB My Book external hard.

We track 33 in-stock listings for this selection on Amazon.co.uk. Offers below are shown as Amazon states them, then compared with the cheapest listings by £/TB.

Removing the drive from its enclosure (shucking) usually voids the manufacturer's warranty, and the drive inside can vary between batches.

Shucked, the cheapest external here works out at £25.83/TB (WD 24TB My Book external hard), against £2.50/TB for the cheapest new bare 3.5-inch drive (IBM 01PL041 DC Ultrium8 LTO8 without).

Deals Amazon is flagging
