Using Sandra to test and compare the Mini-Kart against the Buffalo Clip Drive 2.0, SanDisk Cruzer, IBM Micro Drive, and
the Lexar Jump Drive we can see the OCZ Mini-Kart is slightly faster. Here are the benchmark results:
Combined Index: 3007 operation(s)/min
Endurance Factor: 5.7
512B Files Test: 3838 operation(s)/min
32kB Files Test: 3345 operation(s)/min
256kB Files Test: 1371 operation(s)/min
2MB Files Test: 261 operation(s)/min
64MB Files Test: 9 operation(s)/min
Results Interpretation: Higher index values are better.

Observations:
The OCZ Ultra-Slim Mini-Kart USB 2.0 Flash Drive performed well against the other devices in its class, only being
beaten out by the SanDisk Cruzer Titanium. One negative thing to note is the endurance value that is reported by the
Sisoft Sandra program of 5.7. This is not the lowest of scores, but not the highest either. Endurance factor is a figure
representing the Wear and Life Expectancy of flash devices; this is obtained by dividing the average performance
(normal condition, i.e. sequential write) to the lowest performance (high-stress condition, i.e. same block re-write). It
measures the relative improvement of endurance caused by the wear leveling or flash management algorithm; the absolute
endurance of a device (i.e. its expected life-time) is directly dependent, in addition to this Endurance Factor, on the
nominal manufacturer rating of maximum erase/reprogram cycles, which is typically 100,000+ for SLC and 10,000+ for MLC
devices. (Higher is better, i.e. longer life-time for the device) As the factor is a ratio, it is useful only in
comparing devices rather than having a direct, physical interpretation associated to its numerical value.
