  2. Tutorial – Tutorial Initalize New SSD
  3. How to set up OpenMediaVault on Raspberry Pi 4
  4. Setting the permissions for your HDD /SDD in Raspbian
sudo chown pi:pi /media/pi/<HARD-DRIVE-LABEL> location

Change the owner to pi and all users should have full r/w/x permissions

sudo chmod 777 /media/pi/<HARD-DRIVE-LABEL> location

Make your HDD/SSD readable, writable and executable by everyone

Q1: Does the X857 support USB boot?

A: Please refer to Does the X825/X855 support USB boot

Q2: What msata SSD is recommend?

A: It is not recommend use Samsung brand SSD as there will be electromagnetic interference between the Samsung SSD and X857 which make the SSD can not be recognized, and you can choose other big brand that you like.

Q3: Does X857 support TRIM?

A: Yes, X857 supports TRIM (Thanks for Mark), It will ensure the longevity and performance of mSATA drives.(The important thing is a rule has to be created to tell the OS this and then a cron entry made to schedule it.)
