What kind of SSD for Raspberry Pi when using persistence? Sata, mSata or m.2?

I accidentially answered the wrong thread, but long story short:

• use big HD volumes (to decrease Change of overwriting same sectors over and over again)
• use old-fashioned HDs instead of cheap SSDs
• use the built-in “boot from USB”-Option of the newer Pis

…and here’s the Long answer in the wrong thread:

The Raspberry Pi doesn’t have a built-in interface for HD other than USB. Therefore the form factor of an SSD or any storage device is IMHO not that important. If it’s solely on avoiden data loss of SD Cards - you should go for a device which offers that. SD Cards and SSDs (and USB Sticks) share some basic functionality: SLC, MLC or TLC NAND for Solid State Drives ? :: SG FAQ So, if you’ll go on non-rotating HD (SSD) - have a look on the SLC (pricier!) ones - or use a b…

I am not sure if I understand completely, so you choose old-fashioned HD because it is more reliable than SSD or because it is cheaper?

Are you using persistence?

Did you separate the logs and swapping files like mentioned in this post: Corrupt FileSystems every 2-3 month? - #20 by mstormi

Or is this separation not needed anymore with an old fashioned HD?

Do you know what is the power consumption difference between a SSD and the old fashioned HD? Didn’t find anything conclusive…
