My first post so please be gentle.
Found this in PC world Romford store. End of line clearance so a perfect product at a cheap price.
I have loads of kids photos and keep adding more so am on constant need of premanent safe storage. I have 2 external hard drives that I use for backup but eventually they WILL fail so I find blu ray discs a safe long term storage and with 25gb per disc, the space is also decent. I have previously bought the same product for much more. On Amazon now it is around £1.69.
Therefore if you need to backup loads of data permanently ( e.g. Kids photos and videos) this I think is a good option.
The only constraint is you need a blu ray writer.
