Samsung HD322HJ: Currently my first choice when equipping our business calculator. As the product contains only 1 Platter, it is very low vibration, which had a positive effect on the mechanical durability and noise reduction. Many of the problems associated with TB-plates to be avoided from the outset. The plate is barely warm, which saves energy, the entire PC cooling relieves (less noise) and also has a positive effect on the mechanical durability. The high data density (perpendicular recording) makes the drive extremely fast, especially when it comes Read on sequential.
