All drive manufactures produce similar drives.
Western digital owns hitachi now, seagate owns samsung, and most toshiba 3.5" are rebranded hitachi.
So honestly it doesnt matter which drive brand you choose, as its only a matter of when not if a drive is going to fail. So having adequate backups is critical.
Currently there is a great deal on 4TB Seagate ST4000DM000 on newegg for under$200
Actually, Seagate only bought Samsung's HDD business, not its SSD business.
The only drive that has ever failed on me is a Seagate, but then it was probably five or six years old and gave enough warning that I didn't lose any data.
The rest of my HDDs are Samsung and I can say that I've really abused them and they just keep running. Too bad I can't get them anymore. I just bought the 2TB Seagate at Newegg with a free PCIe USB 3.0 card, a deal even if the card doesn't work in my Mac Pro.
Just to say, I have about twelve or so hard drives with sizes from 250GB to 2 TB in two computers and three external eSATA boxes. I would never buy LaCie externals again, no fans or underpowered fans in their cases means the bridge boards always fail, have three dead cases sitting around while the drives continue to live in the external boxes. Getting cheap externals and filling them with drives works for me, because even if the case fails, just had a Rosewill fail, the internal power circuit died, the drives survive to fight another day.
