USB 3.0 RAID: Storage For Mac Pro Owners with Thunderbolt Envy
Originally posted Thursday, September 1st, 2011, by rob-ART morgan, mad scientist
The owners of 2010 Westmere Mac Pros are likely envious of the 2011 MacBook Pros and iMacs with Thunderbolt. It's not clear if and how Thunderbolt will be implemented on the rumored 2011 Mac Pro. In the meantime, HighPoint Technology has an alternative storage solution. It's a four lane, four port USB 3.0 RAID enabled host adapter called the 'RocketU Quad.' It comes with a RAID Manager that supports RAID 0, 1, 5, 10, and JBOD. It supports hot-swap, too. We ran it through some tests using RAID 0 mode with four 7K HDDs and four 6Gb/s SSDs.
AJA SYSTEM TEST We used the Disk Read/Write test with 4GB file size, 2048x1556 10-bit RGB Video Frame Size, and File System Cache Disabled. Graph shows the average for 335 frames. Longest bar (RED) means FASTEST. K1200s manual.
FINDER DUPLICATE TEST We timed how long it took to duplicate a 6.45G folder with 146 items of various sizes. Then we converted the results to megabytes per second. Longest bar (RED) means FASTEST.
LEGEND of GRAPHS 6Gssd*4 Tbolt = Four OWC Mercury Extreme 6G SSDs inside the Promise Pegasus R4 Thunderbolt enclosure. The Promise RAID utility was used to set up the RAID 0 set. The enclosure was connected to the 2011 iMac Core i7's Thunderbolt port. 6Gssd*4 RockU = Four OWC Mercury Extreme 6G SSDs plugged into four Voyager S3 USB 3.0 drive docks connected to the RocketU Quad. 'Hard' refers to the fact that we used the RocketU's RAID manager to create the RAID 0 set. HDD*4 Tbolt = Four Hitachi Deskstar 7K3000s (2TB) inside the Promise Pegasus R4 Thunderbolt enclosure. The Promise RAID utility was used to set up the RAID 0 set. The enclosure was connected to the 2011 iMac Core i7's Thunderbolt port. HDD*4 RockU = Four Hitachi Deskstar 7K3000s (2TB) plugged into four Voyager S3 USB 3.0 drive docks connected to the RocketU Quad. 'Hard' refers to the fact that we used the RocketU's RAID manager to create the RAID 0 set. The RocketU Quad was installed in slot 3 of the 2010 Mac Pro 6-core Westmere.
INSIGHTS & ANALYSIS When you think high performance RAID, you don't think USB. Therefore, HighPoint has achieved a significant milestone to offer a USB 3.0 RAID capable host adapter that can compete with other storage technologies in features and performance.
Though the HighPoint RocketU Quad USB 3.0 RAID adapter didn't attain the published 20Gb/s theoretical transfer rate, it was close to Thunderbolt in real world transfer speeds. For Mac Pro owners, it's an alternative storage solution worth consideration.
For this article, we simulated a four bay, four port enclosure by using four individual Voyager S3 USB 3.0 drive docks. What would make the RocketU an even more compelling alternative storage solution would be if some company would produce a four bay, four port USB 3.0 enclosure. All existing multi-bay USB 3.0 enclosures use a single port to connect to all drives installed, thereby limited the speed to under 200MB/s.
Neither the RocketU/Voyager combo nor the Pegasus Thunderbolt enclosure taps the full potential of the 6Gb/s SSDs. If you are using 6Gb/s SSDs and want to squeeze out their full speed potential, I recommend a SATA/SAS RAID adapter like the HighPoint RocketRAID 2722 which measured 1500MB/s with four 6Gb/s SSDs in a previous test.

November 21st, 2017, by rob-ART morgan, mad scientist November 30th, 2017, added AHCI results to NVMe
There are three exciting new Thunderbolt external storage solutions. Let's see how they compare in performance to the competition.
GRAPH LEGEND Sonnet Fusion TB3 - Sonnet Fusion Thunderbolt 3 PCIe Flash Drive (1TB, bus-powered) NetStor NA611TB3 - Netstor NA611TB3 enclosure with two 512G Samsung 960 Pro NVMe PCIe based flash blades striped (RAID 0) installed (Power Brick required) Node Lite TB3>PCIe - AKiTiO Node Lite Thunderbolt 3 PCIe Expansion Chassis with Amfeltec Gen3 PCie M.2 Carrier Board with two 512G Samsung 960 Pro NVMe PCIe based flash blades in RAID 0 (Power Brick required) LaCie Bolt3 - LaCie Bolt3 Thunderbolt 3 enclosure (2TB capacity, Power Brick required) SanDisk 900 Extreme - SanDisk Extreme 900 Portable SSD (USB 3.1 Gen2, bus-powered, available in various capacities up to 960GB)
NOTE: 2017 iMac 5K running macOS High Sierra was used as the test mule. Similar results were observed on other Macs with Thunderbolt 3 ports.
LARGE SEQUENTIAL We used AJA System Test to benchmark file level sequential transfer speed using a 16GB test file. HIGHER number in megabytes per second = FASTEST
small random Quickbench's Standard Test includes random transfer test sizes from 4 KBytes to 1024 KBytes. The graph shows an average of 5 test cycles. The speeds are not as impressive as large sequential transfers, it is still a useful metric. After all, a lot of data transfers are small and random. HIGHER number in megabytes per second = FASTEST
WHAT DID WE LEARN?
Up until now all Thunderbolt 3 drives we tested required a power brick. The Sonnet Fusion Thunderbolt 3 PCIe Flash Drive is not only bus-powered and portable, but our testing shows that rivals the speed of the 'brick powered' Thunderbolt 3 drives. In the past, bus-powered Thunderbolt 2 drives were much slower than their AC/DC powered counterparts so this is a breakthrough for fans of bus-power.
The Netstor NA611TB3 Thunderbolt 3 NVMe SSD enclosure is smaller and lighter than the LaCie Bolt3 and most other external Thunderbolt 3 solutions. Its key feature is the 'blank canvas' approach. You get to install the M.2 flash blades of your choice -- blades you may already own. We tested with dual NVMe blades but keep in mind they run natively only under macOS 10.13.x. AHCI flash blades are compatible with all versions of macOS. As you can see from the graphs, our valuable cache of SM951 AHCI blades actually performed large sequential WRITEs faster than the NVMe blades when installed in the Netstor or any other TB3 device we have tested.
Though there are other Thunderbolt 3 PCIe expansion boxes, the AKiTiO Node Lite Thunderbolt 3 PCIe Expansion Chassis is a new, compact example with 4 lane PCIe 3.0 compliant interface that accepts cards with x16 style connectors. And it is fully compatible with macOS (with no need for tb_enabler script). To squeeze out maximum storage performance, we installed the Amfeltec Gen3 Quad M.2 Slot Carrier Board populated with two striped (RAID 0) 960 Pro NVMe blades.
We also tested with four 960 Pros, but the READ speeds were not any faster than with two blades and the WRITE speeds were only slightly faster. The limitation is the Thunderbolt 3 bandwidth. If you want it to work with versions of macOS other than High Sierra, you will want to use AHCI blades like the Samsung SM951 -- which will give you equally fast READ speeds and even faster WRITE speeds (as you can see from the Netstor example in the graphs).
We included the LaCie Bolt3 in this article, even though it was featured in our February 2017 article. It is a viable option if you want both speed and capacity (2TB).
The SanDisk 900 Extreme Portable SSD is the only other bus-powered drive in this shootout. We added it because, at 800+ MB/s, it represents the fastest USB 3.1 Gen2 alternative to Thunderbolt 3 external drives. It's available in various capacities from 480G to 1.92TB.
If you have up to four USB-C ports to spare, there's always the wild USB 3.1 Gen2 solution we created using multiple bus-powered AngelBird SSD2GO PKTs that achieved up to 2095MB/s.
