OWC ThunderBay 4 RAID5 Edition Review – Speed, Capacity and Data Security

RAID0 TESTING WITH 4 X OWC ELECTRA 6GBPS SSDS

Gotta love working with SSDs!  Once again, we will start with PC testing, followed by Mac.

WINDOWS 7 PC

OWC Electra 6G RAIDx4 ATTO

Other then the jump to 1.2GB/s as the final read speed, we determined the highs to be just over 1GB/s for both read and write transfer speeds.  As much as we wanted to discount that last jump, 4 tests in both random and oFill testing resulted in that same last jump in performance.

Performance is just below 1GB/s read and write which is decent but we would have like to see that 1.2GB/s as it would confirm that data is being transferred through both SATA 10Gbps ports.

MAC OSX

OWC Electra 6G RAIDx4 QB

Unlike what we saw in RAID 0 with the hard drives in Mac, there is no jump in performance with the OWC Electra SSDs when comparing Mac RAID0 to that of PC.  Top speeds are 894MB/s read and 852MB/s write.

OWC Electra 6G RAIDx4 ZoneBench OSX

ZoneBench results are solid and do a great job in confirming what we see with QuickBench above.  Let’s take a last look at Disk Speed Test, the meat and gravy of testing transfer speeds in the Mac environment;  things drop just a bit lower yet:

  1. nice, isnt there still a little risk of loosing all data of the discs, when the controller of the thunderbay is dying?

  2. Wow. 500 dollars for a jbod device.

    • It comes with Softraid full software worth 180$ usd. So this unit is fair priced.

    • Not sure about the older units but the one I just bought came with the limited SoftRAID for ThunderBay version which only lets you manipulate drives that are contained within the ThunderBay. It’s plenty powerful for managing those volumes and it seems like a fair deal considering how overbuilt the enclosure is but I would liked to have seen it come with the full software. Upgrading from SRFTB is $99.00.
