Benchmarked below is the 64GB Lexar Jumpdrive S73 formated to have a single ext2 partition. Previous benchmark results of the 16GB Lexar Jumpdrive S73 model, formated to have a single fat32 partition, can be found here.
The 64GB model is commonly found on sale for $44 at Best Buy and Futureshop. On occasion it can also be found on sale for $40.
The 16GB, 32GB, and 64GB model are rated at “up to 45MB/s read, 20MB/s write”. Avoid the 8GB model as it has a lower rating of “up to 40MB/s read, 10MB/s write”.
USB 2.0 Performance is excellent for the capacity and price range. The read speed is around 36MB/s. The write speed is around 20MB/s. Definitely higher end USB 2.0 flash drive performance.
The design is a bulky sturdy plastic that will fit in loose pockets. There is a nicely designed switch to retract the USB plug. Aesthetically speaking, the 64GB model is a pleasing bright green color.
Compared to the smaller 16GB model, this unit has similar read performance and slightly better write performance. Buy the 64GB model for the higher capacity needs and slight increase in performance; otherwise, buy the 16GB for the lower unit cost.
In the end, this is a great low cost high capacity USB 2.0 drive.
