It is apparently like RAID-4 with some caches. Given the obnoxious Usenet posting philosophy of the company that sells RAID 7, I would advise not doing business with them. Given your requirements (2 GB of data generated each week, store it for a year), I would recommend that you pursue solutions which are flexible, i.e. raid devices which allow you to have many separate 16 gigabyte RAID volumes. Some RAID hardware (like the before-mentioned RAID7 product) only allow you to have one volume. If you will be using a database product on this device, it is also often a good idea to be able to create a small mirrored set of disks to hold your transaction logs. -- g
