One day and without warning 2 of those devices (under warranty) stopped working without prior warning.

I would back up 3 times to these 3 devices every night after capturing during the day giving me the original CF or SD card plus 3 backups. I used to travel to 95 countries (mostly out of Paris and NYC before that) and not having those images still haunts me at times.Īs a testament to Graham's SSD failure comment, years ago (yes I am paranoid) I used to travel with 3 independent OWC SSD (the best ones).

Yes I am crazy about backups since in Hurricane Andrew in 1982 I lost 25 years of slides (pre digital) since our house had a 12 foot tidal wave go through it.

And if that is not enough I also have backups of aforementioned on Samsung 2TB SSD which I keep here and update as changes occur. I also keep all of the aforementioned RAID on 4TB Samsung 2.5' SSD drives in a bank vault which I rotate from time to time. Other old RAID machines backup all these just mentioned (just in case) since I live in FL the lightening capitol of the US.

Softraid raid 6 pro#

I have multiple other RAID devices split by RAW USA by location, RAW Europe by location, C1 Sessions by year (all three of these on OWC Mercury Elite Pro Dual-(some 16TB or 14TB or 10TB) and C1 Sessions by location. My most recent one is the Mercury Elite Pro Dock with two 16TB drives on RAID 0-my preferred RAID setup. Even though I have many OWC RAID devices I always pick hard RAID devices. I just do not want to use Softraid for myself. I don't mind reconfiguring the drives they are all backed up with second copies. I don't need any other RAID configurations other than RAID 0.

Can I use Big Sur to configure these drives as RAID 0, or will I still need SoftRaid? I have no idea what RAID capabilities Big Sur's disk utilities have, if any. These are not RAID enclosures, just JBOD enclosures. I have other single drives, but the above are all configured as (3) different RAID 0 drives.

(2) 1TB SSD NVMe drives in one ORICO dual May M.2 enclosure.

(4) 1TB SSD in one Thunderbay 4 (TB2) enclosure.

(2) 8TB spinning drives in one Mercury Elite Pro Dual (TB2) enclosure.

All of them have 1-4 drives in them, all configured as RAID 0 (not between enclosures, just RAID 0 for the drives within the enclosures): I have a few OWC enclosures and one Orico enclosure.

Softraid raid 6 upgrade#

I am preparing to upgrade to Big Sur, but wasn't too thrilled about upgrading to the new SoftRaid v6. I've been using SSD's and OWC's SoftRaid Lite with Catalina. The Linux also tests and reports optimal algorithm for RAID redundancy syndrome calculation for your system on boot, so you can check which one it will use and how fast it'll perform by reading boot logs.Trying to figure out if I need to upgrade to SoftRaid 6 when I migrate to Big Sur. You can also limit its load by limiting the check rate by setting /sys/block/md125/md/sync_speed_max with some arbitrary value ( 200000, meaning 200 MB/sec is the default).

This calculation is quite intensive for the CPU, so it's better to run this check when your system doesn't have much load.

Softraid raid 6 software#

Linux software RAID uses a field that enables RAID6 with no more than 257 active devices (not counting hot spares). A second syndrome is calculated using quite sophisticated mathematics called Galois field. While first parity syndrome is really simply XOR, the second one is not. It is very useful to run the check periodically as it not only will correct misswrites, but also detect and kick out of array dying devices early, so better set up this check to be invoked via system scheduler (cron or systemd timers). You can monitor status via /proc/mdstat file or mdadm -detail /dev/md125. It'll report any important messages to kernel log readable via dmesg. This is important for modern very large disks. For RAID6 it will also correct a single-mismatch errors (when just one drive is went out of sync) by using all the rest drives, thanks to dual parity which enables detection of dual errors and correction of single errors, include those could have happened due to the disk bit error rate. It will read all the drives, compute parity stripes and check if they're correct. Run (replace md125 with your actual array): echo 'check' > /sys/block/md125/md/sync_action
