Maxtor was bought by Seagate some years ago. Toshiba bought Fujitsu's HDD biz. Seagate is also buying Samsung's HDD biz. Western Digital is buying Hitachi.
There will be only three HDD makers: Western Digital will be the largest, Seagate next, and Toshiba/Fujitsu (mostly 2.5").
I am thinking I'll have to bite the bullet and get a RAID, hot-swappable storage box like the Drobo. With more of our lives stored on HDDs, and HDDs getting seemling less reliable, relying on a single HDD is not going to work, even with regular backups.

I recently realized we have 5 HDDs in constant use - MacBook, iMac, Time Capsule backup, TIVO w/ 2 drive. No wonder I'm getting a failure per year.
