Those are internal and i want external but thanks 
You can always get an internal drive and an external enclosure. That way, you know what drive is going into your hardware. Internal drives are usually more consistent in terms of failures too, and so it's generally easier to judge the reliability of internal drives over external ones.
People always worry about external enclosures, but in all honesty, it's a two-minute job to assemble one. If you know how to use a screwdriver and to keep yourself free of static electricity, you're already 95% done.
Green is highly unreliable if it is like you say.
Imagine playing a 1080p anime with a bitrate of 10000kbps.... i guess the data inflow/outflow would be almost the same as for game... and this on a regular basis... it will fail soon like you said.
Green is not unreliable. It is just not recommended for applications where performance is a requirement. If it's just for data storage that is always on but not accessed often, it will save electricity in the long run, because it's designed to spin down when idle for long periods of time.
Playing video or any kind of media is not the same as running a game. Generally, when you play back a media file, you read it from beginning to end. When running a game or some data-heavy application, you access data that is scattered over the disk, so you experience greater delays as you seek for the data. That's why 1080p playback can be smooth even if it's accessing data at a higher rate than a game that lags a lot.
