A:AnswerDepends on how large your games are and how many you plan to keep on it. That will determine if it is large enough - your usage will, not the size of the drive as packaged.
A:AnswerYes.
These USB SSD drives (I have two) are abysmal for write performance. They heat up a LOT when in use and their write performance declines rapidly. Trying to write a 21G file from my local SSD to this USB SSD takes over an hour, but if I just transfer the same file from the same local SSD to an SMB (network) share over 802.11ac wireless, it takes about 4 minutes. Other SSD drives connected to this same computer and transferring this same file that I've used, even from SanDisk (e.g. a 128G microSSD attached via a microSSD -> USB converter), worked MUCH faster and reliably for writes. Read performance appears to be decent and does not heat up the drives as much.
The above is copied from my review that I just wrote before I saw your question.
A:AnswerJerry, please look closer at the specifications: it says speeds up to 10 Gbps, which translates to gigaBITs per second. Not gigaBYTEs, which would be GBps.
Which makes its maximum transfer speed around 1250 megabytes per second, or just 1.25 GBps.
Seeing as this is also referring to the new USB 3.1 standard, your results will vary if you don't have a USB 3.1 compliant port.
