EXCERPT DESCRIPTION
As video images get bigger, faster and bigger storage becomes critical. Enter the RAID. In this short illustrated video tutorial, Larry Jordan explains what computer RAIDs are and the differences in speed, capacity and data protection between the different RAID types.
Explaining Data Storage RAIDs and How They Work
TRT: 8:52 — MPEG-4 HD movie
Wondering how fast your computer is compared to the latest Apple silicon Mac desktops? We have the answers! Larry Jordan spent over a month testing the new M2 Mac Studio and M2 Mac mini computers, along with Intel Macs from 2013, 2017 and 2018. In this webinar, he presents the results of these tests explaining just “how fast is fast” when comparing today’s systems with those over the last ten years.
This detailed analysis includes over two dozen tables and charts in easy-to-read format to help you get the best performance from your current system – or one you are thinking about buying.
In addition, Larry goes into depth explaining what RAIDs are, the differences between HDD and SDD RAIDs, how to determine their speed and capacity and how to decide which RAID is best for your editing style.
This webinar covers:
If you are wondering whether Apple’s latest computers will make a difference in your editing, this session tells you all you need to know.
AUDIENCE LEVEL
This is an intermediate-level session. While not complex, there are a lot of performance metrics discussed.

Thanks for the vid larry very helpful… You recommended RAID 0 or 10 for SSD RAIDS, but did not explain why not RAID 4, which was designed for SSD’s… Why not RAID four for SSD’s?
Rodney:
Because I discovered that RAID 10 provides redundancy and is faster than RAID 4. Which was something I did not expect.
Here are two relevant articles. In the first article, using a Thunderblade, RAID 4 was slightly faster. In the second article, using an OWC Express 4M2 – which is faster than the Thunderblade, RAID 10 was faster.

Both RAID 4 and RAID 10 requires OWC SoftRAID to configure the RAID. RAID 0 is the fastest, always, but provides no data redundancy.
