The product is slow. I purchased with SoftRaid 5.8.4 and SoftRaid 6 was in beta. They had shipped, but I asked them to return the product. I had not received the shipment and I had not opened it. They flat out refused.
Then when SoftRaid 6 came out, which is required for Big Sur, they charged me $50 for an upgrade.
Even worse, when I got it, configured my Raid, my performance was in the 300 Mb range (Read and Write) for three SSDs. This was on a Sabrent 10Gbps JBOD unit. I was expecting much better.
When I tried to talk with tech support, that was impossible, and they used Covid as an excuse. Fine, but via email support was far worse and slow. You could NEVER use this utility for any kind of production, no matter how small. How could you when it would take days for them to back to you? The tech support guy clearly said his goal was to show me that the problem was my hardware. What kind of support is that? How could he ever find the problem when his only focus was to blame my hardware?
Finally, I configured my three SSDs as a Raid 0 using the Mac Raid Assistant. My speeds were excellent; 940 write and 650 read. What that means is that the hardware can produce 10Gbps speed, given the right software.
I'm out over $200 on this software Raid, and I wish I'd never ever bought it. OWC is now on my do not buy list.....I really thought they were a much better company than this!
