One is "SanDISK SSD PLUS MODEL SDSSDA-240GB SATA 6G/s "

THE OTHER IS " SanDISK X300s SD7SB3Q-256G -1006 "

i have a couple of Questions

1) Which one is better ? And newer ?

2) If I connect them to pc the one with 240GB show only 223GB and the one with 256GB Show me 238GB It’s a 15GB Difference in Capacity storage IN THIS CASE

What you recommended ?



3) they both sata III (3) ? if no , its Critical difference between sata 3 and sata 2 ???

4) I plan to used the ssd drive with adapter cable usb Directly to computer like an External Hardisk to backup some files and stuff it a good idea ?

USB adapter connection speed will not fall down?
5) Maybe After a while I'll use it to connect internal hard drive for the operation system so which one better for two cases

I appreciate your help and want to Thanks in advance everyone

Solution
Oops mate , thought the first one was the ultra plus

The x300s is also the faster drive , it is a 2014 model though if its new it doesn't really make any difference.
The ssd plus is newer (2016 model) & slightly faster , the other as you say has an extra 15gb space.

Via USB you won't notice any performance difference whatsoever (& yes ssd drives are fairly good for portable backup storage because they're not prone to knocks or damage)

As an internal OS drive I'd take the ssd plus though.
