I think the real reason is simply money. They put better parts in SSD than in thumb drives. Even the USB3 Sandisk thumb drives I buy are "slow".
No, there is some "technology" behind it. * SATA and eSATA are 'star wired' whereas SB are bus wired. If you have any other USB device around it will slow down (aka convey slowest speed) all otehr USB devices. * SATA and eSTAT are autonomous devices whereas USB are CPU controlled. Disks have a long history of being 'smart' and often integrated with some kind of DMA so that many blocks can ba transfered all at once. With the move to 4K and 4K file systems this can be accelerated. USB isn't actually a character by character device like a UART but it is more demanding of the CPU than a disk. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
