Is a 12X FireWire CD-RW really
50% faster than an 8X CD-RW?

The QPS Que! Fire 12X CD-RW external drive is shipping for Macintosh. Is it worth paying $350 for a 12X when you can get an 8X for $240? Is it really that much faster?
ÊPERFORMANCE ANALYSISIf you are burning regular CD blanks, the 12X drive is 42% faster than the 8X drive (counting burn and verify time). Not exactly 50% but close.
If you are burning rewritable media, the 12X drive burns and verifies 77% faster than the 8X. (Actually, the 12X drive burns the erasable media at 10X and the 8X drive burns the erasable at 4X.)
Although the performance gap widens, I don't know why anyone would use rewritable media. I buy "one time" blanks for 30 cents each. I burn them and either store them, use them or toss them. Why would I want to spend $2 for each rewritable CD blank just so I could fill up my spare time erasing it for reuse?
Besides, if you are using CD's for backup media, you do NOT want to overwrite the previous backup. As a former supervisor of a computer center, I learned the hard way that overwriting previous backups is a sure fire way to perpetuate a corrupted file with no recourse.
COST ANALYSISIs the 12X worth the extra cost? Based on the latest prices, I say YES!
The latest prices have it at $269 after rebate, only $40 more than the lowest price for the 8X.
If that doesn't convince you, there's one feature that may justify the extra cost of the 12X. It's called "Burn-Proof" technology. It eliminates buffer underrun errors in fast write modes. (I hate when that happens.)

TEST CONFIGURATION AND PROCEDURES
The TEST machine: An Apple G4/400 Sawtooth and 512MB of "222" PC-100 memory. Mac OS 9.04, VM off, ATALK off, clock display off, minimal extensions.
CD-RW drives tested:
QPS Que! FIRE 12X/10X/32X FireWire external drive.
QPS Que! FIRE 8X/4X/32X FireWire external drive.
(Both drives use the Plextor mechanism. Both drives include an OEM version of Toast software and one free rewritable CD. Click HERE for Acrobat brochure.)
I take a 30MB file and drop it into the Toast window. Then I do a "Session" burn. I time it with a stopwatch until it finishes writing, housekeeping, and says, "Wanna verify?"
I say "Yes" to "Wanna verify?" and time it with a stopwatch until it says, "You can eject now."
