19 Flash Drive Roundup

19 Flash Drive Roundup

Performance (Normal Drives)

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

The Lexar JD Lighting has some incredible performance and is the only drive to not fall under 26 megabytes per second on the minimum MB/s transfer rate. A very stable drive capable of sustained performance right across the board. At the other end of the scale the Diamond Unit failed to maintain an average of 10 MB/s rate making it around one third the speed of the Lexar JD unit. The Supertalent DG 4GB also put in a good showing just trailing the Lexar slightly on average MB/S.

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.

Tying in with the results above the Supertalent and Lexar drives are tied for first place with the slightly slower OCZ rally being able to pull back into joint first place for random accesses.

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 results are rather interesting for this test with the Lexar and Supertalent drives offering some of the fastest results for medium and large files. However, when we look at small file transfers the Corsair Padlock and OCZ Rally are way ahead of the pack making them ideal for transfering masses of Word, text or database files. The OCZ Rally is actually the class leader for medium (2mb) file sizes and gives a respectable showing in both the other classes, making it probably the best drive overall with the Corsair a close second.

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.
