OWC Mercury Electra 6G 960GB SSD: Aggregate Throughput in OWC Thunderbay Mini
MPG previously tested the throughput of the OWC Thunderbay 4 Mini with 4 X 240GB SSD.
The test is repeated here with four OWC 1TB Mercury Electra 6G SSDs, a new model released in December 2014.
- 4 OWC 1TB Mercury Electra 6G SSD
- 4 volumes, one per drive
- 4 DiskTester fill-volume tests running simultaneously, one per volume.
disktester fill-volume --xfer 128M (per volume)
These speeds are real-world throughput through the OS Xfile system via four processes operating simultaneously on four volumes/drives.
The Thunderbay Mini with four OWC SSDs delivers an outrageously good performance that represents best of breed / best possible: when used simultaneously the Thunderbolt 2 bus is the limiting factor. Performance here is even a little better than the same with the OWC 240GB Mercury Extreme Pro 6G SSDs.
Aggregate* write: 1344 MB/sec
Aggregate read: 1382 MB/sec
Single SSD write: 336 MB/sec (simultaneous with 3 others)
Single SSD read: 345 MB/sec (simultaneous with 3 others)
* Aggregates and averages exclude the spikes at end. Aggregate is a simple total; the speed spikes at beginning and end are when one or two drives starting/ending the test a few seconds earlier/later leave the others free to operate at full speed. The flat-lined areas in the center represent a throttling by the Thunderbolt bus.
