What Affects Mac System Performance for Video Editing? [v]

[ This is an excerpt from a recent online webinar: “Ask Larry Anything!” which is available as a download in our store, or as part of our Video Training Library. ]


“Ask Larry Anything!” is a free-form conversation about video editing technology. In this short video tutorial, Larry Jordan explains what affects computer system performance for video editing, what can slow down your data and what speeds we should expect from our gear. There’s a lot that can affect the performance of your system.

One of our favorite – and most wide-ranging – sessions returns with “Ask Larry Anything!” Presented by Larry Jordan, this session focuses on computer system and storage performance. What determines it, what’s possible, and what holds it back.

This session covers:

If you are wondering whether your system is fast enough, this session will open your eyes into what’s possible — and what isn’t.


These topics range from beginner to advanced. Subjects change quickly, so if you aren’t interested in the current question, another will be along in a few minutes.

    Great info – thanks, Larry.

    A (possibly) related question: for travel, I’ve been using 2 x Sandisk Extreme SSDs as RAID 1 using Apple’s RAID through Disk Utility on my M1 Max MacBook Pro – I’d like to double the capacity – can I create another 2-Sandisk RAID and then RAID together the two RAIDS using Disk Utility? Or another RAID configuration program? Or, must I start over and create a 4-Sandisk RAID?

    Thanks, in advance, for any comments…

      Kinda… but it will be messy. What you want is a RAID 1+0 (10). This takes a pair of SSDs and combines them into a RAID 0. Then, a second pair of SSDs and combines THEM into a RAID 0. Then, you combine those two pairs into a RAID 1. This means that each pair contains the same data, while the speed of the group equals a RAID 0.

      That’s the good news. It can be done.

      The problem is that your current RAID is formatted as RAID 1. You can’t create a RAID 0+1. You would need to copy the data from your RAID 1 someplace else, then build the RAID 1+0 from scratch. The other problem is that Apple’s Disk Utility can’t build a RAID 1+0. However, SoftRAID can. (softraid.com). Once built, however, it will work great.

    thanks for your reply – mistake: I put RAID 1 as my current setup – it’s actually RAID 0 – I’ll look into SoftRAID…

    Thanks, again!
