They have a coupon you can use "PSHOPTECH417" to drop the drives down to $47. I picked up four myself, thanks for the plug.The 7K3000 3TB posted above is sold out. There is another listing for 3TB Ultrastar for $51.99:
Hitachi Ultrastar 7K4000 HUS724030ALE641 3TB 64MB cache Internal Hard Drive | eBay
The spec sheet: https://www.hgst.com/sites/default/files/resources/US7K4000_ds.pdf
But the vendor is refurbforless, the same as the 2TB posted at the top, which Fritz was not fond of.
That is a very useful way to look at it.Here's the thing for me. At SCE's tier 3 prices, I pay $40/yr to run a drive. Pretty much any drive.
2T at 40 is 40/T for the first year and 20/T/yr thereafter.
3T at 50 is 30/T for the first year and 12/T/yr thereafter.
4T for 100 is 35/T for the first year and 10/T/yr thereafter.
5T for 150 is 38/T for the first year and 8/T/yr thereafter
I find my choice shifts a bit once I factor in the operating costs.
