I have been playing with a Sony PXU-MS240 SxS backup device. It’s quite different to my NextoDi NVS2500 even though it essentially does the same job. I will be reviewing it in some detail very soon, but here are my first thoughts.

The key feature is that unit has a removable 240Gb hard drive module. Extra drives are readily available and the removable drives can be used as stand-alone USB hard drives without the main unit. Each hard drive cartridge comes in a sturdy box that is much like a Betacam cassette box. There is space on the drives for labels and the box has an insert sleeve that can be used to write on, just like a tape. Clearly this has been done so that as you fill up drives you can pop them on a shelf for longer term storage as you would with a tape. The beauty of the MS240 is that you never need to off load footage, you just add cartridges as you fill them up.

The main unit is 12 volt powered or can run off a standard EX battery. There is a slot at the front for a SxS card and a big Copy button on the top panel along with the power button and menu controls. There is also a small and very clear LCD display that tells you what the unit is doing. In the setup menu you can choose whether to simply copy the SxS cards contents or to do a copy with full verification in one pass.

Another way to verify your clips is to plug it in to an EX camera. The MS240 is supplied with a USB to Express card adapter. You plug the adapter into an EX’s SxS slot and the USB end into the MS240 and then you can use the EX to  playback any clips on the  MS240 in full HD. This is something the Nexto cannot do. It also means that you could use the MS240 to store finished edits for playback via an EX over HDSDi.

The build quality is good and the range of connectivity is also good with eSATA and USB on the main unit and USB on the cartridges. A 16Gb card can be copied to the drive in around 5 mins.
