ReadyNAS 2100: Data Transfer Rate

Mounting 2.5" drives in a ReadyNAS tray at least for the desktop models is all but impossible. I have a JBOD box whose trays support both. (no screws though) Since the question has come up before, I compared the footprint of the drives and the trays. The set of screw holes in the 2.5" drive closest to the connectors is beyond the bottom edge of the tray. One could drill a hole (if very accurate) in the bottom of the tray close to the edge where the latch hinges but the other rear screw hole is in the middle of one of the large holes in the bottom of the tray. In other words, there is only one spot where one could attach a 2.5" drive to the current design ReadyNAS tray that is used in Duo, NV+, Ultras, Pros and NVX series of desktop models. Adapters won't work because most put the 2.5" drive in the middle since they are used in desktops with cables that can be attached my hand. The back plane of the ReadyNAS had fixed sockets and even putting the thickness of the metal side of an adapter between the one edge of the drive and the edge of the tray would at least put the drive in a bind if not prohibit it's insertion totally. New trays would have to be designed. That scenario in the near future is not very likely.

There have been discussions about 2.5" drives before and for the desktop models, it does not make economic sense as the drives are more expensive and do not have the capacity of the 3.5" drives. Yes the SSD drives are faster, but even the SATA2 drives are faster than the 1GB network interface. However, on the commercial rack mounts with the 10GB options and teaming, that might be a different scenario. I think their trays are different, and some of the older rack mounts have different trays than the newer one, at least from the images, since I have never had my hands on any of them.
