Everyone eventually needs external hard drive space. For most people it might just be basic storage. But if you're a Photo / Video editor you might be interested in fast performance. Or perhaps you're concerned about protecting data from an important project and you want to have a backup mirrored drive (redundancy).
Here's a sub $100 dollar Dual Hard Drive Dock that can do all of those things, while still remaining flexible depending on your needs. With built in hardware, it's incredibly easy to setup. All you need to do is insert blank drives, flick a few dip switches, and press button to initiate your Drive Setup choice.
The Xcellon allows you to dock either larger Desktop 3.5" or smaller 2.5" drives. It even works well with Sandisk Solid State Drives (SSD). And the Dock makes it easy to swap like an old video game cartridge if you happen to store data across multiple drives.
The benefit to these drive docks is you'll end up saving money by just buying bare drives with no enclosures. When your drives are not in use, you can store and protect them in dedicated Hard Drive cases (like these).
If you're even more organized, you can create several different types of external storage and swap between them depending on your needs at the current time.
Using JBOD, the dual drive dock is your basic external hard drive. For each hard drive, you'll see a different Storage Drive on your computer.
Using Span is basic storage but takes both drives and only shows you one single external drive on your system. So that you don't have to think about which drive your footage is store in.
If you're looking for fast performance from your drives while editing videos / photos, then you might want to setup two Drives in a Raid0. This will allow your system to send data between both drives simultaneously. But keep in mind there is no redundancy here.
If you're more concerned about redundancy (mirrored data), then you'll want to choose a Raid1 setup. The data written to one drive is automatically duplicated to the other in case of a hard drive failure. A great way to ensure your important client data is safe.
Not quite as fast as Thunderbolt, but the Xcellon Dual Hard Drive Dock is setup to take advantage of increased capable speeds with the latest Type-C USB 3.1 (and backwards compatible).
