If you deal with enormous files on a regular basis or simply want some piece of mind knowing that your data is copied and stored locally, then a RAID array might be a great storage solution. In short, a RAID array is a group of two or more independent hard drives that work together to basically form one super hard drive.

This definitely isn't a consumer-level product, but if you're opting for the iMac Pro for your business, then this is a huge amount of storage and performance that's nigh-unbeatable. It supports RAID 0, 1, 5, 6, and 10 configurations.

PROMISE Pegasus3

Recommended right on Apple's site, the PROMISE Pegasus3 is 12TB of kickapow. It features four drives at 3TB each (also available with four, six, or eight drives) and two Thunderbolt 3 ports, which are backward compatible with older Macs that support Thunderbolt 2 (you just need a 3-2 cable!).

You can daisy chain up to six devices with this system and you can configure it for RAID 0, 1, 5, 6, and 10. At $1500, this is pricey, but you can go with one of the lesser versions if you don't need 12TB.

Glyph Atom RAID SSD

The Glyph Atom is a bit of an outlier on this list in that it's a self-contained RAID 0 solution, so it's all about performance and pretty much not at all about data replication. This drive is already formatted for Mac and fully compatible with Thunderbolt 3.

It's a 1TB solid state drive, making it perfect for smaller projects, with transfer speeds of up to 770MB/s. This portable RAID solution comes in black, white, gold, gray, and silver, and features a rugged enclosure that's designed to be taken on the road with you. It's perfect if you have all your data stored at home but really need to work on that one thing while you're out.

At $430, it's not a bad deal for 1TB, and there's a 2TB version available for $830 if you need more space.
