Not being on the list does not necessarily mean the drive will not work, it merely means they have not tested them and therefore do not officially support them. These lists cover those make and model of drives that they have specifically tested and often might even list specific firmware releases of those drives. Most if not all RAID system suppliers including NAS systems have compatibility lists. The READ speeds jumped to 375MB/s (AJA System Test).I had a look on the Promise website and the only information I could find suggests that the only officially supported 6TB drive is the Toshiba MD04ACA600.
We replaced the Elgato's 3Gb/s SSD with a TransIntl SwiftData 6Gb/s SSD. However, tests by an independent lab revealed serious unreliability.
One reader measured 377MB/s read speed with it connected to a 6Gb/s SSD - using just bus-power.

The Elgato Thunderbolt SSD is a welcome addition to the increasing variety of Thunderbolt products.Īfter posting this article, we learned that Seagate has released a $99 Thunderbolt adapter for their GoFlex series of enclosures. Again, though faster than the Elgato, it's bigger, heavier, and requires an AC adapter. Pegasus is intended to be used as a RAID enclosure with up to four drives.

We tested with a single OWC Mercury Extreme Pro 6Gb/s SSD for this shootout. We added the Promise Pegasus R4 as a proxy for the larger desktop (3.5") Thunderbolt storage products.
The striped pair config is faster than the Elgato, but it's also thicker, heavier, and requires an AC adapter. (These were not LaCie factory SSDs but rather synchronous 6Gb/s SwiftData SSDs from Trans International). We tested it with a single 6Gb/s SSD and with a dual 6Gb/s SSD RAID 0 set. We, of course, included the only other Thunderbolt notebook (2.5") drive enclosure, the LaCie Little Big Disk Thunderbolt. That's the kind of speed we want to see in a single drive bus-powered Thunderbolt enclosure! Maybe with improvements in Thunderbolt technology those speeds will be realized in an external enclosure. We replaced the MacBook Air's factory module with it.

Notice we included the results for the 6Gb/s Mercury Aura Pro Express internal flash upgrade from OWC. See our ADDENDUM below for the improved performance when we tried a 6Gb/s SSD. CORRECTION: The bottleneck is partly a choice of a 3Gb/s SSD. However, it would have been nice if it could transfer even faster since Thunderbolt has a theoretical bandwidth of 10 gigabit/sec and a 6 gigabit/sec SSD is capable of over 500MB/s. The Elgato blows away all other bus-powered storage such as USB and FireWire. In the words of Ash, the synthetic human in the "Alien" movie, "I admire its purity." It's the ONLY Thunderbolt enclosure that is bus-powered. The Elgato Thunderbolt SSD is just as fast or faster than the internal factory 3Gb/s SSD of the MacBook Air. (We ran similar tests on the 2011 MacBook Pro and 2011 iMac with essentially the same results.) "Test Mule" was the 2011 MacBook Air 1.8GHz Core i7 running OS X Lion 10.7.3.
