Timings - I used the highest quality Blu-Ray & DVD I could find. For Blu-Ray, Gladiator (Sapphire Series) and I processed the extended version. For DVD, the extended edition of The Two Towers, where each movie spans two DVDs.

I have two dedicated RAIDs, each composed of two striped drives with 64k clusters and striped to fully utilize. I rip to one drive and generate the MKV file on the other. Even if you don't have a RAID for extra speed, I recommend utilizing two hard drives.  This is very important. You do not want to write to the same drive that you read from as it more than doubles the processing time due to having to move the drive head after each read & write request. Reading from one drive while writing to another minimizes the head movement.

Gladiator was 45 GB which took 1 hour 23 minutes and 23 seconds with an average transfer speed of 9.71 MB / sec. The generated MKV was 29.4 GB and was took four and a half minutes to create.

The Two Towers was 6.7 GB which took 16 minutes and 15 seconds with an average transfer speed of 7.36 MB / sec. The generated MKV file was 4.61 GB and took 33 seconds to create.

If you have a fast DVD drive, you should get better times than I did with the Blu-ray drive. If you have several, you should be spending most of your time swapping discs.

But if not, simply rip & forget until it's time to swap discs. Watch a movie! Point being, you're not twiddling your thumbs waiting doing nothing while it rips.

Plus, most movies are half the size I used here - these are the extremes.

you are, in theory, legally permitted to create ONE backup copy of whatever you own. Suppose your disc were damaged by something and you had no backup. You have to go buy it again.

I've lost the thread, why again do you rip DVDs and B-rDs you own?

I was going to ask the same question.  As nobody touches my discs, I have no need to protect my investment, and the warning screens don't bother me enough to spend the time and money involved.  I am quite happy sticking the disc in an letting it play.

To each his own I guess.

Not in Germany.* 

*If the content is copy-protected, which it is the most time.

Hey Kulju, instead of being insulting, try this, just shut up. You are one of the...never mind. Notice that I said IN THEORY, I am very aware of laws elsewhere and copy protection which many times prevents the creation of backup. But the theory is that you are legally permitted to create ONE backup.

Well doc, it's not rocket science to make the calculation.

I just cannot understand why you all the time have to exaggerate or even lie. Let me do the math for you, since it's quite obvious that you're not a rocket scientist.

First let's estimate that every one of your DVD's discs have 8GB of data, all audio tracks, subtitles, extras etc. included. That's so generous estimation that we don't have take extra discs to the count at all. You only have a handfull of Blu-rays, so we can leave those out of the equation too. Based on your online collection you have ~6000 discs.

6000*8GB=48000GB=48TB. Since we left out those few Blu-rays out of the equation, let's say it's 50TB. Can you now tell me where did my math went wrong? Where did you get the +100TB?

I'm pretty sure that your claim about 150TB isn't even in the ball park. If I'm wrong, I'm happy to admit that and stand corrected.

While I would Contend that 150 is high balling, 50 is low balling. 

In all realism, you would need to double that to get a true fault compliant raid system.  (I don't know about you, but it would really suck to have a disc fail on a JBOD system)

But you, I believe are correct, though a better estimate would probably be 80 to 90 TB (and that should leave room for growth)

Very true, thus why I eventually went with UNRAID instead of a standard RAID - a lost drive only loses the data contained on that drive - for example, if the parity drive also failed.

I think once my rip project is complete and I have a good idea as to my space needs, I'll build a 2nd one and make a full backup onto it.  But if I decide to build the backup early and my needs outgrow it, adding capacity is as simple as adding another drive (up to the current max of 20).

Another beauty of UNRAID is that I can upgrade any of my 1.5 TB drives to 2.0 TB (or larger when UNRAID supports them) simply by replacing one drive at a time and letting the parity drive rebuild the data - if the new drive turns out to be bad, I can simply put the old one back in with no loss or rebuild.
