Performance

Performance was tested with every possible combination using IDE and SATA drives. A small jumper needs to be changed when a SATA drive is used. Other manufactures have implemented this feature with a switch. An internal jumper is the better choice as you cannot hit it by accident. The entire PCB is constructed so that there is no way to break your drive or burn anything when forgetting to jumper something or when plugging in both USB 2.0 and eSATA at once.

USB 2.0

IDE Interface
A Samsung T133 300GB 8MB cache 7200 RPM was used for our performance tests.


The Vizo Luxon Advanced scores a solid 32.4MB/s at 10% CPU utilization. These are good results for a USB 2.0 hard drive enclosure.




The hard drive is faster than the enclosure throughout most of the test, just the outer rims of the disk are slower than what the Vizo Luxon Advanced can deliver.


ATTO shows us quite similar results when compared to HDTach. Read and write speeds are almost equal which is great for this type of enclosure.

SATA Interface
A Samsung 80GB SATA drive was used for our performance tests.


When a SATA drive is used in combination with the USB 2.0 connectivity, there is a very slight - 0.4MB/s rise in performance, and a 1% rise in CPU utilization. It is safe to say that you will not notice the difference between SATA or IDE drives.


The Samsung 80GB SATA drive can barely deliver the speed of the USB 2.0 interface at the outer rims of the platter during the HDTach benchmark. The small dips are not noticeable and do not affect USB 2.0 performance.


The ATTO results are quite similar and the read and write speeds are almost identical as well.

eSATA

The Vizo Luxon Advanced can utilize eSATA no matter what drive is installed. Both variants delivered very close to normal speeds. This is normal and expected of eSATA enclosures.
