Performance

We used the following devices for our comparison:

• OCZ Rally 1GB
• OCZ Mini Kart 1 GB
• OCZ Roadster 1 GB
• Super Talent RBST 1 GB
• Corsair Flash Voyager 512 MB
• Sandisk Cruzer Titanium 512 MB
• Sandisk Cruzer Micro 2 GB
• PQI Traveling Disk i221 1 GB
• Verbatim Store'n'Go Pro 2 GB
• SuperTalent RBST 1 GB
• A-Data MyFlash PD7 1 GB
• A-Data Football Disk 512 MB
• Thermaltake MUSE external HDD enclosure
• Generic Stick USB 1.1 256 MB

HDTach was used in the following two benchmarks.


This first chart is the average read performance of the i810 drive in Megabytes per second (MB/s). The i221's read performance is very nice at a solid 30 MB/s. This is great for large file transfers.


The next performance chart is one that measures Access Time, which is rated in Milliseconds (ms). When it comes to access time, the i221 doesn't do as well as it did in read bandwidth, but it's nothing major to complain about.


We also use ATTO disk benchmark to see how the drive performed with different sized files. We used the default settings of the application which tested files sizes in the range of 0.5 KB to 1024 KB. If you look closely you'll notice once the benchmark hits the 64 KB file size and larger, the performance leveled off. This always seems to be the case with drive tests, that files 64 KB and larger are what are needed for optimum performance.
