Hello. This adapter is convenient to juggle different hard drives (several operating systems or data). It may come to the location of the floppy, but now it may not be possible to do so will leave as a floppy drive depending on the model of the housing. On one of the two I have, there was a slight shift in contactors that is solved with spacers (washers typically used for motherboard screws) on the part where said contactors are fixed. This adapter fits easily into a rack for 3.5-inch disk in case. The ejection is easy, but it is preferable to ensure the output of the disk. Regarding the data transfer rate, it will forward the disc is able to provide. In conclusion, a product recommended for all those who need to change hard drives or just do not leave their computer without any need to take any. JS.
