EXCERPT DESCRIPTION

“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.

    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…

    Regards,

    Don

      Don:

      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.

    Larry:

    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!
