We have already finished the changes to the SoftRAID code which rely on getting time. With this new CPU, the key changes are the way the processor counts time and the way each of the CPU cores determine if memory has been altered by another CPU core.
#Softraid software driver#
This mean that any number, that was used by the SoftRAID driver to determine what type of volume was in use, had to be swapped around right after it was read from disk and right before it was written back out.
With the switch from PowerPC to Intel CPUs, the major change was that areas of memory which stored numbers larger than 256 were set up in the reverse order in the Intel CPU. There are just a few key areas we will have to change. Just like the move from PowerPC to Intel, for this change, the majority of the code for SoftRAID will not require any changes. In anticipation of the Mac mini arriving next week, we have already started implementing the changes required to support this new CPU. We already have a Mac mini with Apple silicon on our way from Apple, we ordered it registered for one 5 minutes after the web page went live. So of course we’re going to conquer this transition as well. First the one was from Motorola 68000 to PowerPC and the second was from PowerPC to Intel. Let’s start with a little background on the team behind SoftRAID for Mac: We have already been through, not 1 but 2 processor architecture changes. Many of our customers are wondering: Is SoftRAID going to work on Big Sur? Will SoftRAID continue to work on Macs with Apple silicon? Here is an announcement from Tim Standing, Vice President Engineering, OWC. There are still some issues, feel free to post any differences you see, but at least you can be working with SoftRAID now. We have performance optimization to work on for new volumes, but older volumes should be OK.
We are releasing a M1 (Apple Silicon) version of SoftRAID today with the SoftRAID 6 beta. Philip – just stop this nonsense with RAID 0.
