    MP 1,1-5,1 Reinstalling macOS - What about my RAID drives?

    So, I am having to reinstall macOS Ventura via OCLP as I had not realized that would be necessary when changing the GPU. My question is, I have macOS on a separate SSD and two hard disk drives in a RAID 1 configuration, AKA mirrored. Will macOS recognize the two RAID HDD for what they are after...

    MP All Models Seeking use case scenarios for the M2 Mac Pro

    Hey there Forumers, I can’t get over the feeling that there must be some target market out there that is absolutely fine with Apple’s decisions on the M2 Mac Pro. While I still hold my breath (running out of air!) for a setup that allows for more RAM of the traditional variety along with...

    Connecting JBOD HDD enclosure via Thunderbolt Mini-SAS adapter?

    I work in film post production and we often receive footage from our clients on a bunch of HDDs (up to 40 drives in a cardboard box!). We're looking for a device, such as a docking station, that would allow us to conveniently connect as many HDDs as possible, simultaneously, to a single Mac...

    I recently got 4 x 3TB SAS drives plus a 2009 Mac Pro RAID card. Is it true that size limit is 2.2TB for SATA drives but not for SAS drives? Anything confirmed?

    1 Hard Drive 2 Macs

    So I do a lot of video work and, as such, have a lot of storage. I would like to setup an external drive on a MacMini to run Dropbox and have the same drive mount on my MacPro, at the same time, for use of the files. This would allow my MacPro to sleep while the MacMini syncs with Dropbox. I...

    Raid sometimes mounts.

    Hi Everyone! So I put three of my old drives together in a JBOD raid. (8+8+4TB) I set it to be the Time Machine backup for my new drive. (16 TB) Everything seemed to work fine, and it copied everything to the backup. I was even able to copy back some test files. But now it usually refuses...

    WD My Book Duo Dual Drive as JBOD without encryption?

    I received the Western Digital My Book Duo as a holiday gift and am wondering if I can make it work with my Mac by reformatting and using in JBOD configuration without hardware encryption. I'd want to be able to remove the drives from the WD enclosure and use them on their own if I ever needed to.

    Multiple RAIDS (all of a sudden) running extremely slow, at work, and at home.

    I have been using a QNAP NAS 6-bay setup at work for the past 2 years with R/W speeds upwards of 1.4GB/Sec (thanks to 2TB cache and 32GB Ram in the NAS). Until about a month ago those speeds were constant. Now, all of a sudden, I'm hitting 100MB/sec with absolutely no changes to my setup...

    G-RAID with SSDs — should it be faster than this?

    Hi all, I've had an 8TB G-RAID Thunderbolt 3 drive for a couple years and I got tired of the noise and slow speeds with my Mac -- around 380 MB/s -- so I just swapped out the HDDs with two WD Blue 2.5" SSDs. I used the RAID configurator to format the array as RAID 0 and then initialized them...
