Hard drives are continuously getting larger and less expensive, so a lack of disk space isn’t really a burden to anyone these days. Filling up a 2TB hard drive with new data would take some effort from an average user.
Data integrity and reliability are important factors in maintaining a high-quality digital filing system. Two hard drives on a RAID dock provide a step above everyday storage. This precaution may seem like a costly upgrade, but an easy setup like this will cost around as much as getting the hard drives themselves.
Hard drives can be hot-swapped to have a rotation of storage with a USB 2.0 dock. If you deal with crazy amounts of data, then you might be burdened with hard drives all over the place. $160 will get you a 2TB SATA II hard drive and a 2-bay hot-swappable dock to get you started on the road to building up an even bigger data collection.
Storage issues are nearly obsolete with larger capacities being readily available and on sale. Once you’ve filled a terabyte, then you’re ready to fill another one. All of your documents, music, photos, video, and miscellaneous files will all fit on a 2TB hard drive and then some.
