I need a device to backup my NAS via USB. The backup will not be a full NAS backup but just the important data that cannot be re-downloaded again or critical data like personal documents and photos.
Anyway, I have always used 2.5" USB drive for this, but I am wondering if it is worth to actually use an NVME.
- 2TB should be enough to backup what I really need. 4TB would be maybe safer for the future.
- NVME will be much faster. HDD would be slow, in particular the first backup or in case of restore.
- The NVME would be a WD SN770, the HDD would be a WD MyPassport. Price is exactly the same.
- HDD could be more reliable? At least you can see it failing long before it breaks completely.
Note: very very critical data is also backed up every day on an S3 bucket on the cloud.
