RAID style mirrowing card a reality
Just like RAID back up hard drives, we now have RAID back up CF cards. Nice.
Japanese company Amulet is releasing a CompactFlash card that
allows images and video files to be backed up instantly using RAID-style
'mirroring'. In mirroring mode, the card effectively becomes two
storage devices, and records images to both partitions simultaneously.
As such, a 64GB card offers 32GB of actual storage space in mirroring
mode.
Many professional DSLRs offer twin card slots to allow for backup storage (in case of hardware failure) but the new Wise CF Card Duo effectively manages this trick in a single CF card. This may appeal to photographers because a corrupted image means a bad screw up. But the two card system is better. If the card fails would not be rational to think that both partitions will also fail. This is after all not a mechanical device. We shall see.
In its standard mode, the card offers 60/50MB/sec read/write speed, which drops to 30/25MB/s in mirroring mode, making it suitable for recording still images and HD video in both modes. The card can be switched between standard and mirroring mode at will, although formatting is required after switching. The 'Wise CF Card Duo' will be released on June 14th in 64GB (32GB mirroring) capacity - price and availability still to be confirmed. So what else is new.
