[QUOTE="aroy, post: 369739, member: 16090"] 1. I have found that DVD do not last long. I have some which are 7 years old and the data can only be read after a lot of tries (I have verified it on a brand new drive). So I have stopped using DVD. 2. DVD = 4.7GB, 1TB = 1000GB = 212 DVD. Add wasted space due to file system and large file granularity and you can safely assume 225 DVD/TB, so 2TB ~ 450 DVD, a daunting task to write and verify them. By the way even I have over 500 DVD of archived data in 6 large boxes. A 2TB disk will occupy a fraction of that space, be more accessible and data faster to retrieve. 3. A 2TB HDD is much cheaper than 400+ DVD. Just use a slow - 5400 RPM drive for archiving, they are more reliable than the faster drives. Both Seagate and WD have slower drives meant for archiving. Here is what I do at present : . I have 3 external USB drives - 1TB, 750 MB and 500MB. . I regularly copy all the relevant data to these disks, so I have 3 copies on external media. . I have quite a few 160GB, 300GB and 750GB internal HDD. I have copied two sets of very old data to these disks. I have a hot plug cage on my desktop, so once every six months I just check the data - write to a scratch disk and then write it back to the data disk. This ensures that the data is not only correct, but refreshes the disk surface. I future I am planning to acquire a series of 1TB or 2TB external USB3 drives and store all my data in duplicate on them. [/QUOTE]
