Inside a Intenso 3,5″ 4TB Portable Drive

I needed a new HDD for my NAS, the only criteria i had were:
– cheap
– 4TB
– from amazon.de

the cheapest 4TB HDD are around 28,6€/TB (geizhals.de) i found the Intenso
for 30€/TB which i found is a good price. Inside was the Western Digital WD40EZRX which costs 137€ (17€ more) at amazon. A downside of opening the case is losing your warranty. But you can sell the enclosure.

You can open the case by removing the top and bottom Plate. Use an old credit card and/or small screwdriver.

Whats inside the enclosure.
