I produce a lot of podcast content each week: about 45 minutes of clean-comedy, 45 minutes of podcasting how-tos, and almost 2 hours of Once Upon a Time. Since I record in four-channel, uncompressed WAV, process my audio, and keep my master files, this generates up to 5 GB of data per week.
In the image-editing world of Photoshop, the most offensive word is “flatten,” which is removing all ability to tweak previous edits. I feel the same way about my audio. I keep my original, raw recordings, as well as my master project file. The only thing I don't keep is my temporary WAV export that I convert to MP3 with iTunes.
This fills up my hard drive very quickly. So instead of deleting these old projects once the podcast episode is uploaded, I have a digital-packrat in my brain that tells me to keep the stuff “just in case.”
So I burn previous episodes to DVD-Rs. This photo is a spindle of about 80 such archive discs, going as far back at the Ramen Noodle #36.
You might think an external hard drive would be cheaper. But let's do the math:
- The Verbatim 4.7 GB DVD-R (100-Disc spindle) costs $28.84 with free shipping from Amazon.com.
- That's 4.7 terabytes (TB) of storage for $28.84.
- Even if I average 4 GB per disc (depending on how large my episodes are), that's still 4 TB of storage for under $30.
- 1 TB external hard drives seem to average $100, while 4 TB external hard drives are around $280.
- Thus, my DVD-R storage costs less than a penny per gigabyte. An external hard drive would cost about ten times that.
Speaking of which, I should probably order another spindle. This last Verbatim DVD-R 100-Disc spindle has lasted for more than a year.
