This is a interesting and scarey thread I need two new drives for my nas box.The two 500 gig raid 1 drives are full. Instead of delleting the dross,and sorting the hundereds of dupliate photos.I have decided to install two 1 TB drives,and start again.Hitachi look the best but a bit pricey for me.
I have three WD passports.All working well.Currys have 1TB WD drives that look the part 49.99 each.The NAS only gets turned on occasionally when I need it.Maybe once a week.I think that they will do for me.
One of the scarry things mentioned is dirty shutdowns.
To shutdown my DLINK-320 box I have to hold the power off,button untill it flashes,then wait for it to shut down.It take awhile,so I normaly switch it of at the socket.No dead drives ,And they are seagate barracuda Drives.
Though with new 1 TB drives installed I will take more care shutting the box down.
I notice that these WD drives are SATA 111.I presume that will not be a problem
