19 Flash Drive Roundup

19 Flash Drive Roundup

Performance (Mini Drives)

Notes: Higher Avg transfer rates are better. Large differences between the Min and Max transfer rates indicate less stable drive performance.

The Supertalent drives all showed amazing performance, especially for this "mini" style group test. The ATP Petito leads the way however with the highest transfer scores. There are really no bad results in this group test and even the lowest performing Kingston Datatraveler can hold its head high.

Notes: Random access time indicates the time the drive needs to arbitrary access the sequence of data stored inside it. Lower random access times are better.

Again the Supertalent drives are showing some amazing access time reads and they all tie the lead with the Twinmos Unit. The top scoring ATP Petito from the last test has just slightly higher access times (0.1) which would be barely noticeable under real world conditions.

Notes: More operations per minute indicate better performance. To ensure a wide variety of test results we tested with folders containing various sized files. For example if you worked often with small database files or word documents you would want a drive capable of transferring smaller files faster. If you work more with larger files, such as RAW files from a camera you would want more performance with 20+megabyte files.

The ATP Petito gives an absolutely blinding set of results even outperforming the fastest drives on the previous page in all the tests! Nothing in this test even comes close to the performance of the ATP unit.

Notes: Endurance factor indicates the wear and life expectancy of flash drives. This is done by dividing the average performance of the drive (sequential write) to the highest stress performance (same block re-write). Higher is theoretically better. In practice each flash device can do a set number of write and erase operations in its life cycle and so when comparing two drives which can do the same number of operations in their lifetime the faster drive will have a lower Endurance Factor because it would also die faster, despite that it is going to do the same number of operations as the slower drive. This test is somewhat subjective as obviously no two units of the same make will have the exact same lifespan.
