Using AJA and BlackMagic I found little difference between using DU and SoftRAID. In each case I set the RAID-0 transfer block size to 128Kb. The TB4m was directly attached to the MBP using Apple's USB-C-to-TB2 adapter.Īfter configuring these 4x BarraCuda drives as RAID-0 using both DU and SoftRAID I used AJA, BlackMagic Disk Test and the Terminal command dd to establish some data rates for each. I ran the tests under Catalina 10.15.3 (Build 19D49f) on my late 2016 15" rMBP13,3. The 5TB disks were freshly erased and formatted as HFS+. With this unclear issue of which is best, DU or SoftRAID, I’ve spent a limited amount of time to see just what the differences are configuring RAID-0 on a set of 4x 5TB 2.5” Seagate BarraCuda 5400 RPM spinning disks in an OWC Thunderbolt 2 mini 4 enclosure (TB4m). I’m unclear what the basis is for this claimed 85%. In some articles I’ve read there’s mention that SoftRAID offers as much as 85% better RAID-0 performance than for DU’s RAID-0.
