Hi,
I am looking to buy a 4TB SATA hard drive. Use case is backup about once a week with and external dock, looking for files every now and then.
The general idea is that I would have two of them, and use the method of storing them with one pebble to indicate where to backup next, so I have one security copy always.
Speed is not important, durability is. What should I buy?
Look for NAS/Enterprise grade drives (they are all cmr) with the best $/TB ratio and warranty time. There is really not much difference between alternatives from different brands.
