I don't think so Tim. If it's running in RAID 1 as implied then it's only ever going to store 750Gb.While hard drive advances are impressive, losing 1TB of data is not likely to be much fun in the future. That is why devices built around a technology known by the fearsome name of Redundant Array of Independent Disks (RAID) are becoming more popular. One such is Seagate's 1.5TB device that is actually made up of two 750GB drives.
A continuous backup is created by the same data being written to both drives simultaneously.
Also:
Oh yeah, really attractive :icon32:For reliability and endurance, optical storage is considered one of the best options. Holographic disks start at 300GB capacity and store data all the way through the disk rather than just on the surface.
Data is written using a split laser beam which creates holograms in the light sensitive material of the disk at the point of intersection.
"The drive will be $18,000 (£9,135) list price, so that's a little bit outside the average consumer's price range. And then the media will be $180 for one disk.
"That's quite a bit of money, but on a cost per gigabyte perspective it's very, very attractive."
