Backup your data whether you use SSD, spindle HDD, 3.5" floppy disks, tapes or punch cards for storage!
Definitely back up your data if you use a SMD
IIRC there was an SMD Z Edition which, although old technology, was quick and reliable. Since the SMD J Edition it's slowed down a bit and only comes in beige.
Well you are partly right, although the J edition is significantly bigger than the Z edition it has far more useful features and is actually quicker than the J in many situations
And due to its sequential processors it has no lag either
