I use these for archival storage. They are also good for a small NAS box. This drive rotates at only 5400 RPM. Be aware this is a specialty HD not appropriate for many purposes. Warranty is not at a SCSI level. But the three years you get is better than one year.
I saw this deal first on SD at $85 with a coupon. That is a good price. You can do better as follows:
Next sign up for a new account.
IGNORE the $120 price you see there and add the drive to your cart. Now go to your cart.
You should be seeing the $80.99 price in your cart.
They nailed me for state sales tax, which is annoying. Still, $80.99 is a good price for 4TB of high reliability storage with a three year warranty. And shipping is free.
If it is speed you want instead: Run away from this deal, dude. Run far, far away.
