The question is as simple as that really. Are bluray disks the cheapest storage medium per gb?
I am recording video which is using about 32gb per day. So a month of that would be almost 1Tb. A year around 12tb.
I want to store at last a years worth with the possibility of more if needed. To me it seems that cheap bluray disks world be the cheapest solution.
But I wanted to get this confirmed.
No, LTO tapes are cheaper if you have very large volume (because the drive is expensive). Another hidden cost of Blu-ray is the very slow burning speed. However, in your case, blu-ray is the most economical solution as your volume is not big enough. – billc.cn – 2012-11-17T13:52:24.433
Looks like LTO tapes + drive only become cheaper than Blu-Ray disks + drives if I want to store 7+ years of 12Tb a year. For 1 year of 12Tb using LTO will cost me around 770GBP, but the Blu-ray solution will cost 250GBP. 2 years of LTO will cost 870GBP and 2 years of Blu-ray will cost 440GBP. – oshirowanen – 2012-11-17T16:34:02.383
Yeah, one major advantage of LTO is that you can reliably re-use the tapes, which is good for backups that only needs to be available for a few months. But I guess that is not relevant to your case. – billc.cn – 2012-11-17T17:39:29.980
