I need new NAS. drives these Toshiba's fit the bill. Fast enough , quiet and work without error they were a little more affordable than the Seagate or Western Digital. They work, no flags, no errors no worries, no one even thinks about them. Making them the perfect NAS drive. Just there working quietly in the background.

Fast Mechanical Drive

Got this for a side drive for my PC, to store large files and run backups and VMs off of. Sure, its not the quiestest drive of all time, but its very quiet compared to several mechanical drives I have had over the years. Fast too. Very fast. Cheap storage that doesn't light up my ears with annoyances and fast too? Sign me up! Its not a Seagate either, which is always a bonus in my books.
