Fusion Dual 2.5-inch SSD RAID

Fusion Dual 2.5-inch SSD RAID is a full-length, full-height PCIe 3.0 card from Sonnet Technologies, Inc. that accomodates two standard 2.5-inch SATA SSDs, with a hardware RAID controller, and also offers a 10Gbps USB-C port. Features include RAID 0, RAID 1, Span, and JBOD modes (selected via external switch), 15-watt power delivery, status indicator lights, and performance “up to 1,000 MB/s.”

Fusion Dual 2.5-inch SSD RAID is due for release by the end of this month at $129.95 for Mac Pro models or external Thunderbolt PCIe enclosures that can hold a full-length, full-height PCIe 3.0 card.

MacDrive

MacDrive is software from OWC Digital for using Mac-formatted drives on Windows systems. Features include support for reading and writing unencrypted, non-Fusion HFS+ volumes; formatting, partitioning, and repair; plus support for Target Disk Mode, DVD/CD, flash drives, etc. It also supports Time Machine backup browsing/copying, as well as access from Boot Camp, VMware Fusion and Parallels. A Pro version even supports SoftRAID RAID 0/RAID 1 volumes, mounts Mac sparse disk images, creates Mac ISO files, burns Mac Blu-ray discs and offers automatic file defragmentation

MacDrive 10.5.4 is priced at $49.99 for Windows 7/Server 2012 and later with a free 5-day trial available. MacDrive Pro is priced at $69.99.

MacDrive 10.5 APFS beta offers preliminary support for reading (but not writing) unencrypted APFS volumes, but the company warns about Apple’s APFS performance problems with hard drives:

While APFS does offer many advantages for Mac-formatted SSD drives, its performance on traditional platter hard drives is significantly worse. As a result, if you are going to be moving files back and forth between a Mac and a PC on a non-SSD hard drive, we recommend keeping your drive formatted as HFS+.

Keeping the drive HFS+ gives you the ability to both read and write to the disk on a PC with MacDrive, while retaining the ability for the drive to be mounted on non-High Sierra Macs.

Mercury Elite Pro Dock

Mercury Elite Pro Dock is an interesting new Thunderbolt 3 enclosure from OWC (macsales.com) that combines dual drive bays, a hardware RAID controller, and a number of connections – sort of a combination storage device and Thunderbolt 3 dock.

Connections include dual Thunderbolt 3 ports, DisplayPort 1.2 (supporting up to 4K), Gigabit Ethernet, a front-mounted SD 4.0 (UHS-II) card reader, and two 5Gbps USB 3 Type-A ports. Both 2.5-inch and 3.5-inch SATA drives are supported, and the RAID hardware handles RAID-0, RAID-1, JBOD/independent, or span.

Mercury Elite Pro Dock is priced from $299.99 sans drives to $1,299.99 with two 14TB hard drives.

SoftRAID

SoftRAID (from Other World Computing Inc.) is a Mac disk formatting, partitioning, testing and management app with full RAID capabilities (RAID 0, 1, 1+0, 4 and 5) on any combination of Thunderbolt, FireWire, eSATA, SCSI, USB, SAS, and Fibre Channel hard drives and SSDs.
Features include bootable mirror volumes, bootable SoftRAID DVDs, fast rebuilding of mirror volumes, a very useful disk certification (testing) feature, SMART data monitoring, email notification of problems, SSD TRIM support (for OS X 10.7 and up), a command-line program (with help), workarounds to protect against Apple macOS kernel bugs, and much more.

SoftRAID 5.8.1 is priced at $179 for OS X 10.7 and up, with a fully-functional 30-day free trial available.
Note that SoftRAID doesn’t currently support Apple’s Core Storage volume format, for FileVault and Fusion drives, and macOS 10.13 (High Sierra)/APFS also needs special workarounds for startup volumes. See also: SoftRAID Compatibility Notes and FAQ.

The latest SoftRAID release follows an Apple bug fix:

New features in version 5.8.1:

• Removes the test to see if the user is running macOS 10.15 with SIP enabled. You can now run the SoftRAID application on macOS 10.15 with SIP enabled. The bug, in macOS 10.15, which caused SIP to be incompatible with SoftRAID, is fixed in macOS 10.15.1.

SoftRAID Lite is a personal version of the app, with RAID-0 and RAID-1 capabilities, disk health monitoring and many of the other features of the professional version, but not support for higher RAID levels (4, 5 and 1+0), email notifications nor Terminal commands. Customer support is via the Internet for SoftRAID Lite, while the professional version includes direct phone support.
SoftRAID Lite is priced at $49 with a free trial available. Direct phone support is a $99 option for the Lite version.

Full SoftRAID functionality for Apple’s new APFS file system (which was introduced in an undocumented version with macOS 10.13 and then revised and made mandatory with macOS 10.14 Mojave) is due in 2020:

SoftRAID 6.0 will be fully compatible with APFS disks and volumes. You’ll be able to create and manage APFS volumes and SoftRAID 6.0 will also offer extra functionality to allow you to further manipulate APFS volumes. At the same time you’ll still get all SoftRAID’s great existing functionality, whether you’re working with APFS or HFS formatted disks.
