Benchmarks: AS SSD Benchmark

The get-go AS SSD Criterion test focuses on sequential read performance and here we encounter that a unmarried OCZ Vertex 4 or Intel SSD 520 Series SSD can achieve a throughput of just over 500MB/s using the SATA 6Gb/s interface. Nonetheless, placing the Intel SSD 520 Series drive in the Duo reduced its throughput to merely 366.5MB/s. The Velociraptor HDDs on the other hand delivered like operation when connected to the motherboard as they did inside the Duo. Notwithstanding, given the functioning of the 520 Series, it's possible that the Velociraptor drives are maxing out the performance of the Duo.

The sequential write results are a flake different to the read performance above. The 520 Series bulldoze achieved a throughput of 285.3MB/south when connected to the motherboard's SATA 6Gb/south port and this was reduced to but 243.5MB/s when using the Thunderbolt interface with the Duo, while the Velociraptor drives managed 375.8MB/south when connected to the motherboard and hit merely 352.9MB/s in the Duo.

Because SATA supports Native Command Queuing (NCQ), information technology has a distinct advantage in the Every bit SSD Benchmark 4K-64 Thread benchmark. Regardless of whether we measure read or write functioning, SSDs connected to the SATA 6Gb/s interface are going to be much faster. The Velociraptor drives on the other manus are the bottleneck here and non the interface, so there was no deviation in functioning when using Thunderbolt or SATA.

The Velociraptor'south access time is like when using either Thunderbolt or SATA, though the latter was slightly faster when measuring reads. The 520 Series drive, however, was notably faster when connected to the motherboard'due south SATA 6Gb/s port.
