Jeff Atwood escreveu um post sobre Coding Horror sobre flash USB grande conduzir performances . Eu recomendo que você leia o artigo completo. Abaixo está um trecho:
Modern 2.5" hard drive performance looks something like this:
HDD Sequential Read 55 MB/sec HDD Sequential Write 55 MB/sec
But what about large USB flash drives? How do they compare to typical hard drive speeds, much less the awe-inspiring Velociraptor? X-Bit Labs recently reviewed three 32 GB USB flash drives:
Type - Sequential Read - Sequential Write
32 GB Corsair Flash Voyager - 22 MB/sec - 10 MB/sec
32 GB OCZ Rally 2 - 30 MB/sec - 22 MB/sec
32 GB Patriot Xporter XT - 31 MB/sec - 17 MB/sec
