From RAID0 to RAID6: Your guide to RAID storage

Don’t know your RAID1 from your RAID0, which capacity drive to go for, or whether you want a mobile or desktop drive? Our handy new guide to RAID storage reveals all…


Go for this if…

You need the ultimate peace of mind that your data is backed up.

How does it work?

RAID1 takes a system with at least two disks and mirrors them, so even if a disk fails, you’ll still have all your data intact.

Our thoughts…

The tradeoff for complete protection is capacity, so a 6TB (2 x 3TB) dual-drive configured in RAID1 will give 3TB of capacity. We recommend RAID1 for archiving and backup where you need to be confident your work is safe.


Go for this if…

You need faster transfer speeds rather than fail-safe security.

How does it work?

RAID0 takes a system with two or more disks and stripes them together (combines several disk drives into a single volume). So on a 6TB drives with 2 x 3TB disks inside you’ll have access to the full 6TB on a single volume on your computer. Striping drives together in RAID0 not only opens up higher capacities but it delivers much faster speeds. As there are multiple hard drives in the RAID set, your transfer speeds are not limited by the speed of a single disk. The more disks you add to the RAID, the faster the transfers will be.

Our thoughts…

As there’s no level of data protection from RAID0 and there’s more than one disk involved, the data on the drive is more exposed to disk failures. We recommend RAID0 for editing high-resolution images and video directly off drives where you need the faster transfer speeds but make sure you already have a second copy of the data backed up.

For RAID0 and RAID1 we recommend…

Mobile drive: LaCie 4TB rugged RAID Thunderbolt and USB 3.0 hard drive, £274 (£328.80 inc VAT)


Desktop drive: G-TECHNOLOGY G-RAID removable 8TB Thunderbolt2 and USB 3.0 hard drive, £550 (£660 inc VAT)



Go for this if…

You need the best of both worlds: fail-safe redundancy and extreme speeds.

How does it work?

RAID5 takes a set of at least three disks and stripes them together for faster speeds and higher capacities. But unlike RAID0, it also protects the data from the risk of drive failure. Under RAID5 each disk in the RAID set contains a copy of data stored on another disk. The end result is that even if a drive in the RAID set fails, you’ll still be able to recover all your data.

Our thoughts…

The added level of protection that RAID5 gives you means you’ll have to sacrifice a small amount of capacity. RAID5 gives you one-drive protection, so in a 4 x 2TB RAID5 array, you’ll get around 6TB of usable capacity, and in an 8 x 3TB RAID5 array you’ll get around 21TB of usable capacity. Because of the extreme speeds and fail-safe protection RAID5 provides, we recommend it for backing up, archiving and editing high-resolution video and images.

For RAID5 and beyond we recommend…

Desktop RAID: G-TECHNOLOGY 24TB G-SPEED studio XL 8-bay Thunderbolt2 RAID array, £2145 (£2574 inc VAT)



Go for this if…

You need multiple disk protection.

How does it work?
Just like RAID5, RAID6 stripes drives together for faster speeds, but provides two drive failure protection rather than just one. While RAID6 sacrifices around two disks’ worth of capacity, the added level of protection is perfect for 24/7 environments, or where the RAID array is hidden away from view and not easily accessible.

Shared Storage 

Go for this if…

You’re working on a project with multiple people and will all need access to the same media files.

How does it work?

Shared storage solutions deliver all the benefits of RAID6 and beyond, as well as added benefits such as intelligent media asset management, collaboration tools, file sharing, backup and recovery. We can help you deploy fast, scalable shared storage systems that make the most of your digital assets.

Which connection should I choose?

To get the most out of RAID you’ll need to think about the connection you want to use. While legacy interfaces like FireWire 800 and eSATA are still supported on RAID drives, to attain the fastest speeds you’ll want to look for the latest interfaces like USB 3.0 and Thunderbolt 2.

USB 3.0

The USB 3.0 protocol is fast enough for dual-drive RAID0 and RAID1 drives. In three or more drive RAID5, the USB 3.0 interface will become a bottleneck, so it’s better to look at Thuderbolt2 drives if you need even faster transfer speeds.

Thunderbolt 2

The Thunderbolt 2 interface has an insane amount of bandwidth, which is enough to run an 8-bay RAID array, that will deliver up to 1350MB/s – enough to edit 4K video from a single drive.

Thunderbolt has the added bonus of supporting daisychaining. So, from a single Thunderbolt port on your Mac or PC, you can daisychain up to six Thunderbolt devices together. If you’re low on ports, look out for Thunderbolt drives that only have one port on them, as these will take up a single port on your computer or can be used at the end of a daisy chain.
