But Im wondering if anyone can speak to general performance or reliability between 4-drive RAID 10 arrays in the Mac Pro 5,1 using the internal Disk Utility.
I have a software license for SoftRAID, and like the monitoring tools it provides. You would have to do RAID 0 or 1 in hardware and then stripe or mirror as needed on the software side to get the 1+0 or 0+1 array you truly wanted and at that point no TRIM support would apply just as if you did RAID 10 entirely in hardware. If you are working as a Linux System Administrator or Linux System Engineer or you are already a Storage Engineer or you are planning to start your career in field of Linux or you are preparing. Hi guys, Havent been able to find much info on this. However, this only guarantees you redundancy for a single. One drive may fail per subarray in a RAID 10 setup. The amount of disks available for RAID 10 is the number of disks in the array divided by two. Unfortunately on the Windows side of things RAID 10 is not supported as a fully software based raid level. RAID 10 is also known as a stripe of mirrors since the data is striped across the entire array, but within the subarray, the data is mirrored. Doubly so for Vista and XP which can't create software RAID volumes.
That leaves Server 2008 32bit, Server 2008 64 bit (not R2), Server 2003 (all versions) out on this. That would mean software RAID 0, 1, or 5 could support trim if I'm right. Windows 7 and Windows Server 2008 R2 support Trim. Essentially if speedfan, hdtune, and such can see SMART data I would expect the Trim command to make it to the drive. You would have to be sure to plug the drive into a drive controller that doesn't have BMC or RAID support. As all software raid on the windows side treats the drive as a single drive.
