Best hard drive for video editing 4K ProRes workflows 2025
What's the best hard drive for professional video editing in 2025?
The OWC Envoy Pro SX stands out as the top choice for professional editors working with 4K ProRes footage. It delivers up to 2,800 MB/s speeds, operates silently, and requires no power cable — perfect for high-end commercial editing workflows.
Why the OWC Envoy Pro SX works for commercial editing
After 20 years of running Mejias Post, I've tested nearly every type of hard drive imaginable. The OWC Envoy Pro SX has become my go-to choice because it matches exactly how I work.
My specialty is short-form content — mostly 30-second broadcast commercials. Projects rarely exceed a few terabytes, and I typically edit alone. When I do work with an assistant editor or co-editor, we share project files rather than accessing the same drive.
Speed matters most because I'm usually cutting footage from the Arri Alexa or Sony Venice. I'm dealing with 4K Apple ProRes 4444, and sometimes RAW formats with very high data rates.
Speed performance that handles multiple 4K streams
The 4-terabyte version retails for $599 and advertises speeds up to 2,800 megabytes per second. In real-world testing on my Mac Studio, the speeds aren't quite as high as advertised, but still excellent.
I can run six, eight, or ten streams of 4K Apple ProRes 4444 in my timeline with no issues. Understanding data rates helps put this in perspective. Professional video editors think about emotion first, but technical specs matter for smooth playback.
Here's something that confused me for years: the difference between megabits and megabytes. Camera data rates use megabits per second, while hard drive speeds use megabytes per second. There are eight megabits in a megabyte.
When 4K Apple ProRes 4444 shows a data rate of 1,000 megabits per second, divide by eight to get 125 megabytes per second. Now you can easily compare to hard drive speeds.
Key advantages for professional workflows
The Envoy Pro SX checks every box for my editing requirements:
- Bus-powered with no power cable needed
- Completely silent operation — crucial for audio work
- Small, rugged case that travels well
- Blazing fast performance for multiple video streams
The only limitation is the 4-terabyte size cap. When projects exceed that limit, I need other options.
Think like a broadcast editor and you'll understand why these features matter for client work.
When you might need network attached storage instead
If you keep large amounts of raw data or need multiple editors accessing the same drive, consider adding a NAS (network attached storage). You'll find plenty of YouTube videos explaining NAS setups, best brands, and configuration.
The honorable mention: Apple's internal SSDs
The only drive I like more than the OWC Envoy Pro SX is the internal SSD in my Mac Studio. But there's a catch.
First, almost anyone can buy the Envoy Pro SX and use it with Mac or PC. Getting an Apple internal SSD means buying a new Mac.
Second, upgrading Apple's internal storage is expensive. I maxed out my Mac Studio with the 8-terabyte SSD, and it's almost always my first choice for editing.
The speed difference is dramatic. My internal SSD tests over twice as fast as the Envoy. It would be challenging to max this drive out even with multiple streams of Arri Alexa RAW.
For editors with a use case similar to mine, the OWC Envoy Pro SX delivers professional performance without the premium price of Apple's internal storage. The combination of speed, portability, and reliability makes it the clear winner for commercial editing workflows.
