Test System:
Testing for this drive was conducted with the following system:
| Operating System | Windows Vista Ultimate 32 bit, SP1 |
| Processor | Intel Core 2 Duo E4600 |
| Motherboard | ASUS Commando |
| Memory | 2 x 1GB Corsair XMS2 DDR2-800 |
| Video Card | Sapphire Radeon HD 4830 |
| Hard Drive 1 | Seagate Barracuda 7200.8 160GB SATA-150 |
| Hard Drive 2 | Seagate Barracuda 7200.10 320GB SATA-150 |
| Hard Drive 3 | Seagate Barracuda 7200.11 500GB SATA-150 |
| Power Supply | Coolmax GreenPower CUG-950 |
SiSoftware Sandra:
SiSoftware's Sandra is a full benchmarking suite, covering a wide range of different subsystems. We used the physical disk read test, to measure the raw throughput of the drive.

 |
| Normal | Turbo |
With TurboHDD USB disabled, Sandra recorded an average read throughput of 29.77MB/s, which is fairly respectable for a USB drive. With TurboHDD USB enabled, the average speed jumped to 35.89MB/s, a difference of 6.12MB/s. Not earth shattering, but certainly a noticeable jump.
Crystal DiskMark
Crystal DiskMark is a disk-oriented benchmark utility that measures read and write performance in a non-destructive manner. Each test pass does a sequential read/write for the selected size, and random read/write tests for 512k and 4k blocks of data.

Performance was fairly uniform across the board, with large files seeing the most benefit from enabling turbo mode. On files 50-1000MB in size, enabling turbo mode resulted in an average improvement of 8.49MB/s for reads, and 5.35MB/s for writes. You won't be mistaking this drive for an eSATA model any time soon, but these are certainly good numbers for a USB drive.
