buffered write slower than sequential?

Greetings,

I have this USB flash disk. When I write to it, it only does so at 800kb/s, while specs say 2.8mb/s. So I ran a benchmark, and it showed that

Buffered Write : 752 kB/s
Sequential Write : 2647 kB/s
Random Write : 1914 kB/s

how come buffered write is slower, and how do I go about fixing that? It's really slow!

thank you.

anyone..?

well i tried looking around the internet but didn't find anything valuable.. im out of ideas, isn't buffering supposed to make it faster?

No, because it's not a buffered sequential write.
That's about as fast as USB1 flash drives go.

well isn't the whole point behind buffering to make operations work faster, by first using memory, and only then slow storage devices?

anyway, it's USB2.0 device, and mobo supports USB2.0 aswell. As I said, rated write speed is 2.8mb/s.
