    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...

    MP 7,1 4TB OWC Accelsior 4M2 card not showing full capacity.

    Hi, I have a Mac Pro with an 4TB OWC Accelsior 4M2 PCIe M.2 NVMe SSD Adapter Card. The card is setup as a Raid and formatted to APFS. The card seems to be working well. However I've just noticed that although the files on the drive only total around 400GB, it shows that I only have 1.3TB of...

    Joining 3 NAS Drives into 1 Virtual Drive

    Hi all, I'd really appreciate some advice. I have three 2-bay WD MyCloud EX2 Ultra enclosures, each running RAID1 on twin 4 TB drives that hold mainly videos of racing events, movies, and TV shows. I use a mid-2012 Mac Mini (Catalina) as a Plex (movies & TV shows) and Emby (races) server...

    FileVault2 Corruption, External hard drive encrypted RAID no longer accepting password.

    I have an encrypted hardware RAID (OWC Mercury Elite Pro Dual) that is MacOS (Journaled, Encrypted). This was created via Disk Utility a few years back. Disk Utility is saying the drive is in great shape. I am on BigSur 11.4 but have access to other macs with older OS'. Suddenly the external...

    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...

    MacPro 5,1 macOS Catalina/Big Sur boot on RAID with OpenCore

    I have read through the forums and it looks like it is impossible at this moment. @tsialex told me condescendingly that OpenCore doesn't just magically make this possible (For context: https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/post-30067481). That ended the...

    Why is Mercury Elite Pro Dual Raid SLOW to respond?

    19,1 iMac, Big Sur 11.4, Mercury Elite Pro Dual RAID (2-6TB hard drives independently configured): My question is why are the RAID drives so slow to awaken when Big Sur queries them especially in the Saving Menu. Maybe 15 sec have to go by before the RAID drives awaken for Big Sur. RAID...

    Need to migrate a RAID10 array to a better storage solution

    I have been using a Mac Mini 2012 as a file server. I upgraded the storage to a four disk HFS+ RAID10 array in an [external RAID enclosure](https://www.newegg.com/orico-3559rus3-bk/p/0VN-0003-00023?Item=9SIA1DS0CD0629) via macOS Disk Utility. However, I have had a lot of trouble with the storage...

    MP 1,1-5,1 Use Mac Pro as NAS/RAID with more than 8 hard drives?

    Hi all, I'm in need of a NAS with large capacity and redundancy (RAID) but I have limited money and want to upgrade it over the next few years. Per year I will produce 12-16 TB of data which I need to save securely somehow. First of all I considered a full-blown NAS. But they are too expensive...

    High Sierra will not install on compatible MacPro5,1 with RAID

    (edited for clarity) Hey guys! The last time I posted you guys were incredibly helpful, and I hope someone can point me in the right direction. Current specs: And the hard drive setup: I bought this computer as-is from my old place of work. The drives are all probably non-OEM, and I'm...

    WD My Book Duo: Use device raid/encryption or Disk Utility?

    Hey there, just got a WD My Book Duo. I'd like to set it up as a RAID 1 and use encryption. Question is, do I use WD's utility to set up RAID and encryption? Or just use Disk Utility? The drive has Hardware Encryption, which I guess won't be used if I enable encryption via Disk Utility? Same...

    G-Speed Shuttle TB3 RAID Compatibility?

    I am currently on tech support with G-Technology and they believe that the G-Speed Shuttle TB3 is compatible with Apple Silicon M1 / Big Sur; however, I cannot get my drives to mount on the new M1 MacBook Pro. Has anyone had any luck mounting G-Technology RAID drives on their M1 Silicon machines?

    G Speed Shuttle Thunderbolt 3 RAID not working with 2015 MBP via adaptor

    Hi I've been given a G-Speed Shuttle Thunderbolt 3 RAID to edit from but it doesn't seem to work on my 2015 Macbook Pro. I've got a 2015 MBP running Mojave. I've tried using a USB-C to USB-3 cable from the RAID into my MBP but no luck. I then found a Thunderbolt 2 to USB-C (I think, it might...

    RAID always working since Catalina

    Ever since installing Catalina, I've noticed that my RAID is constantly working. It never stops. The data seems fine and the drives aren't reporting any issues. I'm just worried that all this non stop reading/writing is going to break something. Is there something in Catalina that would cause...

    MP 7,1 Slot Utility App on New Mac Pro

    Is anyone familiar with how the Slot Utility App functioned on the old Mac Pro? I plan on getting the new Mac Pro 2019, and want to know how bandwidth can be allocated in respect to a lot of the "Pro-Apps" that Apple has teamed up with. If I planned on adding on PCIe NVMe RAID Cards that...
