“What's the difference between a SSD and HD External Drive? I need an external drive to back up my MacBook Pro using Time Machine. Not sure of the difference between these two. Also, for a 256G Mac, is 2T overkill?”

SSD stands for solid state drive, (No moving parts) - think if a larger 'Thumb' drive. and External Drive can be an SSD type (no moving parts) or 'disk type' (older technology where the data is stored on disks that spin around) . You can get a lot more capacity with older Disk types. I like SSD type drives, much quieter and I can get the storage I need at reasonable costs. Also, they travel well (because they don't have any moving parts, less opportunity for something internal to move or damage the drive.
Sorry, there was a problem. Please try again later.SSD has a faster read/write speed as it uses flash memory chip. the HDD uses a disc style. As for being overkill, it's always better to have more and not need it, than to not have enough storage. It really just depends on how much storage you think you'll need. 2T would be like having the storage of 8 of your Macs. (1TB = 1,000GB)
