SSD unfortunately without function

Delivery took place as always quickly and well packed. Unfortunately, the SSD neither directly via SATA, recognized even via USB (external housing) of Windows 7. Since I had ordered a total of two SSD's from Samsung, and both were not recognized, I have contacted the Samsung hotline. I was proposed to send in the plates there, as there is a full three-year warranty on the panels. However, I have taken the path of return to Amazon. Money was refunded promptly from there! The assigned rating is therefore to be regarded as such for the Amazon service, not for the product! Maybe it has been a total defect batch, such things can happen, but should be excluded from the manufacturers through inspections. I bought a computer already installed with Samsung SSD that runs stable there for two weeks !!!
