That said, they're expensive, but if you really want those photos, I know at least one lab provides free quotes. I would say that depending on your location, I know of a couple very good data recovery labs. It's expensive up front, but in the long run, it's far cheaper to invest in a proper backup, than it is to even send a single drive out for data recovery. Like I said before, Buffalo, Drobo, and other NAS or external drive arrays would be the best thing going ahead in the future. RAID0 is meant more for performance, but I think you'd negate the performance increase with the second pair of drives, so it wouldn't seem any faster or slower than a single drive.Įither way, if you want to make things easier on yourself, look for external arrays that use RAID built in, rather than putting it into a computer. I can't say I've noticed any impact on performance with RAID1. In terms of performance, the quality of the RAID controller you go with could severely impact performance, especially with RAID1+0, as you essentially have to wait for a write sequence to occur twice on separate arrays. I saw a unit reject one hard drive, but work fine with an identical one. Drobo units are very solid, though picky about hard drives. I'm not a massive fan of the software for Buffalo, but it works, and works well. I've seen plenty of mixed reviews, however I've never personally seen these units go bad. I would suggest looking into external RAID units such as Drobo or Buffalo NAS units with RAID1, and using them only for data backup and long term storage. There's no substitute for having a backup system that works for you. RAID10 or 1+0 would be 4 drives minimum, and while it's a serious backup option, it's beyond anything I would set up for a client unless they specifically asked for it. Each network share is a RAID1 array, and has an automatic incremental backup going to an eSATA drive which is only a local backup for the server (not a network backup). In one particular case, a business has the most "secure" server in terms of data loss prevention. I manage the hardware aspect of several small business servers, and they do have RAID arrays in them to avoid data loss.
