The First Blu-ray Burner, Pioneer's BDR-101A 181
mikemuch writes "ExtremeTech has a review of Pioneer's BDR-101A-- the first Blu-ray burner available. The drive can do anything with CDs, is kind of slow with DVDs, and doesn't support double-density Blu-ray media, but hey, it's a start, and can burn 25GB in 42 minutes. Check out its burn speed benchmark performance at the link above."

Anyway, the Blu-Ray disks are $19-29 USD. I will need to wait until I can buy a spindle of 100 Blu-Ray disks for 9.99 before I go out and buy one of these things.

This just about sums up the entire article: Wow, neat. Don't buy one yet.

Now, right before the PS3 release, Blu-ray burners are available in the same price range. Even the media is similarly priced. If history repeats itself, which it always does, you should be able "backup" your PS3 games for under $400 in about a year.

Hey, I remember when blank CR-Rs were in the $10-20/disc range. RAM cost $50-$100/megabyte (not gigabyte). And DVD burners were still on the horizon at $15,000 each. And we likedit. (Hell no we didn't!)
Create/burn PAR2 files with your backups (Score:5, Informative)
For those that don't know, PAR2 files are parity files that can efficiently reconstruct missing or damaged blocks in your archive. If you have more PAR2 recovery blocks than damaged blocks, then you can completely reconstruct all of the damaged files in your archive. The best newbie explanation I've seen is the "PAR & PAR2 files" section [slyck.com] from Slyck's Guide To The Newsgroups.
If I'm backing up to a data DVD-R (capacity 4,706,074,624 bytes), I'll leave around 4GB of space for the actual data and fill the rest (to the brim) with the PAR2 files that I created for that data. I name the PAR2 files starting with the letter 'z' so that they get burned on the outer edge of the DVD. When creating the PAR2 files, I choose a block size that is a multiple of 2048 bytes because that is the block size of a DVD sector.
Some easy-to-use tools to create PAR2 files:
Some DVD data recovery software (to get every readable block off a damaged disc):

Interesting idea with the PAR2 files though.

Which I've always thought was odd since:
* 44,100 samples per second per channel
* 2 bytes per sample (16bit audio)
* 2 channels
44,100 (samps/sec) x 2 (bytes per samp) x 2 (channels) = 176,400 bytes per second or about 172kb/s in the old meaning of kb/s.

- Don't buy the Blu-Ray burner. Save $1000
- Use the $1000 to buy 10x 250GB external HDs. This is equivalent to 40x Blu-Ray disks
If you expect to burn more that 40 Blu-Ray disks AND expect the price per GB of Blu-Ray media to go below that for HDs (keep in mind that the price per-GB of HD media is going down fast), then go ahead and get the burner.
By the way: Reading and writting data to an from and external HD, even via USB is actually much faster than to and from a Blu-Ray disk. Still, if that's a problem buy a Firewire external HD enclosure and 10x 250GB internal HDs
Yes, you get more "effective" data rate from CD-DA (Score:3, Informative)
You can still use these extra bytes for extra capacity if you use Mode 2 (VCDs use this), at the cost of ECC.
In either case, the CD (assuming 1x read) still rotates at exactly the same speed, whether it is a CD-DA, CD-ROM Mode 1 or CD-ROM Mode 2 disc.
