The hard disk has a great capacity of 2TB. I've purchased a second hard drive bay of my laptop. The installation worked fine, but you need a little standard metal housing for mounting in the laptop (my laptop was in there). The above mentioned power connector remains unassigned with me and has no consequences, so described as above. The performance of the drive is fine, mediocrity, but I use it also as a primary storage.
So a strong buy recommendation for those who want to increase their memory properly.
