Frequently Asked Questions (FAQs)

1. Can I use a USB drive as a NAS?

Learn more. The SimpleNET from SimpleTech is a super simple (sorry, couldn't resist) way to turn a USB hard drive into a NAS device (network attached storage). Just plug this small module into your wireless router and then plug one or two USB hard drives into the USB ports in the module and you're done.

2. Is NAS faster than USB?

Basically, a NAS server's speed varies between the speed of USB 2.0 and the speed of USB 3.0, and is much slower than the speed of Thunderbolt, which gets up to about 700MBps. Note that 130MBps is in no way slow; in fact it's very fast, even faster than the real-world speed of many internal drives.

3. What is a NAS enclosure?

A network-attached storage (NAS) enclosure is a storage device that provides hard disk drive (HDD) capacity to devices connected to a network.

4. How long do NAS enclosures last?

They live an average of three to five years. The correlation here is all on the inside. Servers and hard drives both contain vital moving parts that make them susceptible to failure.
