Hey So I read the above pined post and it had lots of good information but I'm still unsure of what to go wit. Option seem to be:
With the falling price of SSD's I can get a 120GB SSD for around $30-$40 Canadian. it won't be the best brand but it won't be a garbage no name direct from china brand either (i.e. ADATA or Kingston, maybe Crucial)
Guaranteed trim support
A little more expensive
Uses a SATA port (though that's not a big deal for me right now)
USB flash drive:
CHEAP! (<$15 for a Sandisk 32GB USB3.0 drive)
Unknown reliability (though Sandisk brand helps in this respect)
No TRIM support
SD Card and card reader:
Possible trim support?
A 32GB card + Card reader will be in the $30-$40 range (same as the SSD)
No guarantee I'll be able to get TRIM working. I did an experiment with my current SD card and card reader on a Ubuntu 16.04 system and was not able to get trim working. I'd hate to spend all this time and money just to find out the new one wont work either.
Big, and will likely block other USB ports.
I'm currently leaning towards one of the first two option, but would like a second opinion especially with respect to the lac of TRIM for a USB drive.
