[QUOTE="aroy, post: 344931, member: 16090"] I agree, except that you can have a reliable RAID in a desktop. For a reliable RAID, you need at least 5 disks, preferably 7 with a hardware RAID controller, so that you can rebuild the data after 1 bit failure. For greater redundancy use other modes which can rebuild 2 bits or more, each bit will add another drive for error correction. I have put Adaptec, or used IBM RAID, in Servers and they are pretty reliable. A lower cost approach is to use a HDD backup utility which will just backup the files modified (or new). This has to be a part of your daily routine, as in my experience the data is lost the only time you forgot to back it up. For my Images I do the following . Copy the Images from card, keep the images on the card. . Process the images, generate jpeg for the relevant images. . Backup both the RAW and jpeg to two external disks - RAW and jpeg in one, and zipped RAW in another. As Nikon NX-D uses sidecar files for editing history, even if I loose jpeg, I can get then back from RAW. . Once The data is backed up, I erase the images on the card. My card can hold 1600 RAW images from D3300, but my battery requires a charge between 350 and 600 shots. So I format the card every time I charge the battery. . If I am outstation, then the images are kept in two cards and I process them when I return. [/QUOTE]
