First of all, this is an external HDD that can be used by both Macs and PCs – and even on gaming consoles. It can do what storage devices are supposed to do. But what makes it stand out is its superb durability.Although it can resist bumps and accidental drops, it can still be damaged if you deliberately throw it around. However, it’s tough, and its warranty will back that up. The company is going to provide full services for three years if anything goes wrong. The SP Armor A30 is an excellent storage device if you’re the type who travels a lot. The price is quite higher than the other products here. But it does assure you that your data is safe no matter how rough the road – no more random corrupt files.
