USB Flash Drives
First, I am not referring to memory sticks or those flash cards used in
cameras. Sandisk, Lexar, and over a dozen manufacturers make USB 2.0 Flash Drives that go from 128 MB up to 2 GB in size. They have transfer rates like some hard drives. (1) How many times can you re-write over the data on these thumb sized devices? (2) What governs the wide range of transfer rates? I'm leaning toward the Sandisk Cruzer Titanium 512 MB. |

I've just ran an old copy of SiSoft Sandra on it. Thought you might interested in the results Buffered Read 8 MB/s Sequential Read 8 MB/s Random Read 5 MB/s Buffered Write 1670 kB/s Sequential Write 1730 kB/s Random Write 462 kB/s Average Access Time 5 ms (estimated) The same data for my internal WD 100G C: Buffered Read 84 MB/s Sequential Read 21 MB/s Random Read 4 MB/s Buffered Write 75 MB/s Sequential Write 27 MB/s Random Write 6 MB/s Average Access Time 11 mS (estimated) Quite a difference. |

You can get devices with as low as 10.000 overwrites and as high as 1.000.000. If the manufacturer does not say, assume the worst.

I have the Cruzer Titanium and I'm very happy with it. In addition to
being a great tool, the metal casing protects it well. I know a bunch of people with the plastic ones with bent or broken off tips. It's also pretty small by comparison to most every other one on the market, with the exception of the Cruzer Mini (which are plastic and prone to getting smushed) to your questions: there doesn't seem to be a practical limit to the number of rewrites you can do. Sandisk doesn't make a note of it anywhere in their literature. The biggest factor in the transfer rate is USB 1.1 vs 2. Next you get into the design of the devices, the performance and quality of the flash memory, and the quality of the manufacturing process used by the company. Usually this means that the faster drives will cost a little more. Dan "Pat" wrote in message news:6VH5d.15513$M45.15116@trndny09...
