Sandisk Extreme 500, Enable TRIM OSX?

Hello, 

i would like to inform you that first of all the portable ssds cannot be used as system and bootable disks since it was planend to use as a secondary and storage drive. so you wont be able to enable the trim option on the drive and i do not think that it will hold up as a system drive and will fail in a very short time

so i suggest using a normal sata drive in that case to ensure that the drive will work fine with the system.
