I wonder if I should buy a Seagate/WD 2.5" 4TB and install it internally via SATA as a backup drive to save power

Sure it would work fine .  And SMR is perfect for backup purpose.  Not to mention, there is a way to refresh it

You mean versioning, right.  I'm doing exactly the same thing.  However, I will only keep 10 versions of each file.

New SMR disks have TRIM just like a SSD, this kind of SMR HDDs don't need to refresh to gain back performance.

I did not use Veracrypt coz I need that 2.5" 4TB to be very portable (can be read by any PC w/o the need of add-on software).  However, I did use Veracrypt to create encrypted vaults (on other disks) for specific needs.

About backup tools :
While fastcopy (freeware) is my favourite file copy tool (I rarely use freefilesync now), I'm using the non-free VIceVersaPro (https://www.tgrmn.com/) as the primary backup software.  One of the best features of VVP is the support of encryption by file level (in .enc).  

There are freeware backup tools that generate single encrypted ZIP backup file, which is basically non-usable when we are talking about a backup size of say 2TB (and we need to handle incremential or update modes) !  In contrast, VVP generates individual encrypted enc files, which is fast and effective.  Not much software in the market having such feature!

回覆 29# harryytm

ST2000LM015 is 3.5", right?

And does it mean that my ST4000LM024 4TB 2.5" is a kind of old model?
