List the data transfer rate. bps B/sec bit byte USB3.0 SAS3.0 PCI-Express
The comparison of the data transfer rate. How to connect?
'8 Bit = 1Byte 'generally known.However, it may become '8 bit ≠ 1Byte 'for various reasons.(Calculated by 'binary (1024)' or 'dcimal (1000)'.Transfered by '8 b/10b medthod 'or '128b / 130b method'.)
Is a complex area. Please consider the following list as a simple table. (Wrong with ignorance, it might be a typo.)
Please compare the list to install the extension interface data transfer rate. Should be connected to any review.
For example, if you wanted to try adding an 'USB3.0(5Gbps)' is good to use an expansion card transfer rate than PCI-Express1.1×2(5 Gbps) or PCI-Express2.0×1(5Gbps).
The difference between theoretical and actual values.
Between theoretical and actual values ??are different.
USB2.0 transfer rate is 60MB. However, in many cases the measured value of about 18MB.
May not use the Blu-ray 4x bottleneck in USB2.0.(Theoretical value is a 4x Blu-ray Disc drive, you can not rule out possibility of a low measured value.)
Theoretical value of the SSD connected by SATA3.0 is 500MB/s. The fastest measured value was 368MB/s. Actual value will change in firmware and software as well as the connection method. To find out the actual measurements, please use the CrystalDiskMark2.2.
Reported that many see 'USB3.0 is Not very fast'. In time, I think there could be improved. If you think focusing on the transfer rate may choose to connect SATA or eSATA. But it may be a highly versatile USB connection method. It is a good judge in general.
