I use 2.5" 2TB hard drives for backups. I typically get Seagate drives from Amazon but it appears that they no longer sell them. Other sellers still do, but the Seagate warranty won't be honored if I buy from them. I checked all of the authorized resellers on Seagate's website and none of them sell these anymore. Seems to also be true of WD drives. I can get 3.5" drives, but they are too big for backups I keep in a Safe Deposit Box. Is this the end of 2.5" drives?
