Copying a single 6GB file to the OCZ Enyo using MCCI's optimized USB 3.0 host driver took just 1 minute. The drive was so fast that it actually outperformed the OCZ Vertex 2 and Intel X25-M internal SSD hard drives. Without the aforementioned driver the Enyo was 44% slower, taking 1 minute and 28 seconds to complete the same task. When compared to the 2 minutes and 7 seconds of a conventional SATA 3Gb/s hard drive, this is still very fast nonetheless.

But the OCZ Enyo is really designed to replace existing portable storage solutions such as USB 2.0 hard drives and flash memory sticks. So how did it fare against those? As you can see, the A-DATA SH93 took a staggering 7 minutes to transfer the single 6GB file, making it seven times slower than the Enyo when using the MCCI drivers. Even when limited to the USB 2.0 bus the Enyo was still quite snappy, at least as far as USB 2.0 devices are concerned.

To quote some actual numbers, the OCZ Enyo sustained an average transfer speed of 93MB/s with the MCCI drivers, dropping to 65MB/s without them. A high speed internal hard drive such as the Samsung Spinpoint F1 using the SATA 3Gb/s bus only managed 48MB/s, whereas a typical USB 2.0 device is limited to just 13MB/s.

The program copy test is made up of many small non-compressed files, rather than a single large file like in our previous benchmark. As you can see the Enyo is not quite as impressive when handling multiple smaller files. In fact, it is now slower than the internal SSDs using the SATA 3Gb/s interface. With the MCCI Drivers the Enyo sustained 65MB/s, taking just 22 seconds to complete the task, compared to 17 and 18 for the Intel X25-M and OCZ Vertex 2 respectively.

Without the supplied driver the Enyo became 36% slower, with the transfer rate dropping to 49MB/s. This was a few megabytes per second slower than a conventional hard drive using the SATA 3Gb/s bus. However, even at this speed the Enyo was about 4.5x faster than a typical USB 2.0 storage device.

The game copy test comprises of a mixture of small and large files. Here we see that the OCZ Enyo with the MCCI drivers fares quite well, taking just 13 seconds to complete this task, matching the Intel X25-M while slightly outperforming the OCZ Vertex 2. Without the supplied drivers the Enyo took 19 seconds to complete the same task, as transfer rates dropped from 102MB/s to just 69MB/s. In this scenario the Enyo was still 25% faster than the Samsung Spinpoint F1 hard drive, and as much as 5x faster than a typical USB 2.0 storage device.
