5400/5900rpm vs. 7200rpm NAS drives for video editing

[Lloyd]

Hi All,

 

I'm looking to purchase some hard drives for a 4-bay OWC Thunderbay 4 (Thunderbolt 3), I imagine 4x 2TB would be sufficient, creating an 8TB working array in RAID 0. The footage would be backup up to another storage array to protect against any potential drive failures.

 

What functional benefits would I see from using 7200rpm (WD Red Pro/IronWolf Pro) vs. 5400/5900rpm drives (WD Red/IronWolf)? The advertised data rates don't seem to be that much of an improvement so I'm curious to know if the seek times would affect the responsiveness of the timeline, etc. In addition, I can pick up 2TB IronWolf drives for £59.99 each, whereas IronWolf Pro drives are £94.99 each.

 

Thanks for any help you can provide!

The pro lines come with better warranties and included data recovery.  I use WD Red Pros in my NAS, they're great.  #NoRagrets

Does not protect, do not recommend. I'm partial to RAID 6.

For video editing scrubbing though footage better seek times could help but I believe the impact is also dependent on how big the files are you're working on. The difference between 5400RPM & 7200RPM is going to be about a 30% improvement in throughput so if you RAID0 two of them you should see about a 60% improvement over two 5400RPM drives.

 

5400RPM drives are good for low power storage applications while 7200RPM is more ideal for active high(er) demand applications. I think scrubbing though footage the throughput would be more important than the seek time since the whole video file should be in the same location on disk it's not jumping to random locations (where better seek time would make an impact)

I understand that, however I'm looking for maximum throughput. A copy of any footage would be stored on a separate array.

Thanks, I thought no that settles my query, I guess I'll just wait for a decent deal on some IronWolf Pro or WD Red Pro drives.
