Workflow is one of the most crucial parts to any form of business, especially when it comes to the creative industry, from massive post production firms doing video editing to photographers. With the current 4K, moving to 8K and higher resolution still images for photographers, being able to quickly offload these files to a real time storage device with a level of redundancy on said storage is becoming a challenge, not to mention meeting deadlines without interruptions.
One might think that their 8TB or 10TB USB portable hard drive from the local retail shop is already top dog for their workflow, as it can offer them capacity and portability, but increasing your storage capacity is not the only factor to take in to consideration. Transfer speed, redundancy, and future proofing are just some of the aspects which contribute to an optimized workflow. Lets look at the technology behind it first.
USB 3 has long been a standard and well known to many. It has a theoretical data transfer rate of 5Gb/s or around 600MB/s – it might all sound impressive but ever wonder why your portable hard drive is still taking ages to copy your files when it has such impressive speeds? 600MB/s is only the potential throughput, or to put it in simple terms, how big the pipe is. We also have to consider the max transfer speed of the single hard drive inside. A normal desktop hard drive has transfer speeds of around 140MB/s – 220MB/s, and that’s the max it will reach on average. More realistically your USB 3 portable hard drive sits at around the 40-125 MB/s and that’s not consistent either, the speeds will fluctuate or peak depending on what you are copying (Please see the below image for USB 3 Portable Hard Drive speed test.)

On the other side there is Thunderbolt storage. You might have come across these terms from the Apple store, but what makes it different? Thunderbolt works entirely different from USB, it comes with active cable chip set to control data flow to ensure that it’s performance is consistent. Thunderbolt 2 (the previous generation) can offer up to 20Gb/s and the new Thunderbolt 3 can offer 40Gb/s of data transfer rates, 8 times that of USB 3!

Now earlier we talked about it being pointless having a huge data transfer rate when the bottleneck is still relative to the single hard drive. Most Thunderbolt storage devices come in multi-bay options. Having a pool of hard drives working together concurrently allows you to increase the load on more hard drives as opposed to just one – you are simply writing to all the hard drives at the same time which increases performance dramatically. Normally they will also be working in a RAID group which will offer you hard drive redundancy in an event that causes 1 hard drive to fail, meaning you won’t lose your data, as well as additional storage ranging from 12TB, 24TB, 32TB and 48TB.
