How fast usb3

Our USB 2. Interestingly, the write speeds for the files on folders tests were faster using the hubs, going from FireWire was about half as fast as USB 3. The read scores were faster, though at Thunderbolt turned in scores nearly identical to the USB 3.

Again, USB 2. We saw the same MBps scores across all tests, with or without the hub. In this case, USB 2. It has to go through before it reaches its destination. I have enough computers in the house with USB 3.

Try transferring something when the CPU and RAM are under heavy load and watch that transfer be sluggish all day long. But the case here is that people are seeing slow transfer from USB 3.

My point is in any spindle based external drive, you hard disk transfer rate from the magnetic head to the cache to the SATA interface would be your bottle neck, not the USB 3. The way to get anywhere close to the true colors of the USB 3. The only way to not have that bottleneck is to get a PCI-E 16x m.

So the chart is correct. There seems to be some confusion here about the transfer speed in terms of how it is specified. Technically, a lower-case b indicates a bit, an upper-case B a byte. This theoretically means there is an 8x difference for the same speed- 8Mbps megabits per second is equivalent to 1MBps megaBytes per second.

These can seem dramatically different despite being the same speed. The other issue is data throughput. An 8GB file can appear to have a lower bit rate than the specifications because the specifications are for so many bits per second. So an 8GB file takes up more, which will effectively make the drive appear to be slower than its actual Mbps rate. Manufacturers obviously prefer the decimal version because it make drives seem faster and bigger. However, the file sizes might be referring to the binry version and again will appear slower.

So basically, as usual the advertised speeds are pure BS and false advertising since speeds never reach near that. Theoretical means nothing when it is physically impossible to reach those speeds no? Yes… and No. See the problem with going with the theoretical speeds is….. So therefore you cannot say the theoretical speed of this bus is Mbps because, say in 2 years, they can come out with a device than can reach Mbps on that same bus connector.

See what I mean? BUT, I will say…. It is false, toss an SSD drive into a USB3 enclosure i have done several and see if you get anywhere near M even, you wont, you hover around up and down…they Oh and AWW people with speeds that will never exist on the standard..

You probably arnt too far off the mark. Source — had to write specialised usb2 drivers once with some pretty demanding speed requirements and data accuracy requirements.

It is pure false advertising. You are right that it is a lot of marketing hype to list just the raw speed, as this is of no benefit to the end user. I purchased a USB 3. Can I connect a Thunderbolt 3 device to a Thunderbolt 2 Mac? What is the actual data transfer rate for USB 3.
