CrystalDiskMark 3.0.3 is a good benchmark to gauge how well a drive will perform. Many of the drive manufacturers have used this benchmark to show off the performance of their drives. It provides a quick benchmark of Sequential and Random read/writes, and included a NCQ with a queue depth of 32.
The SuperSpeed USB 3.0 performance testing was done using the Kingston HyperX 3K 120GB SSD and a Thermaltake BlackX 5G SuperSpeed USB 3.0 dock.
|Sequential Read||Sequential Write||4k Read||4k Write|
|ECS Z97-PK Deluxe||355.3MB/s||175.3MB/s||16.36MB/s||26.81MB/s|
Benchmark Results: The ECS Z97-PK Deluxe motherboard was able to reach 355.3MB/s sequential read, and 174.1MB/s sequential write speed in CrystalDiskMark, which is a little slower than using the onboard SATA III connection.
