I bought this particular SSD to use as an external boot drive for my 2017 i5 5K 27" iMac. It was recommended by the software publisher Carbon Copy Cloner, which I used to clone my internal boot have HDD to this SSD.I first reformatted the SSD and then cloned my internal boot disk according to the instructions on it.I was very disappointed with the performance,it was very slow especially on startup.The next day I went through all the steps again and can be quite snappy when using the machine, the machine still seems to take a bit longer to boot than the internal drive but not too slow overall I think it's worth the money for the price Also the seller was very responsive .
