M-Disc optical media reviewed: Your data, good for a thousand years - markssugh1947

You're done with optical discs as a means of data and media delivery, or soon will be. But when done right, as it has been with Millenniata's M-Disc, sense organ has a primary advantage—longevity. Hard disk mechanisms fail, and the information stored on them can be erased past magnetic fields. Tape stretches and is likewise magnetically vulnerable. NAND North Korean won't unlikely forever, because cells leak and eventually fail. That leaves M-Disc looking pretty good in the media preservation, aka archiving role.

Optical is dead. Long live optical.

In the enterprise, natural philosophy has enjoyed continued success. Companies much as Sony and Panasonic own continued development some because of its longevity and the minimal environmental defend it requires. You think your disc drive generates a lot of heat energy? Try operating thousands of them. AC bills can be rather high.

This diagram illustrates the difference 'tween dye-based and inorganic recordable optical discs.

The advent of relatively unstable, dyestuff-based CD/DVD recordable and rewritable, as good as the lack of prize standards governing them, caused many users to forget that pressed optical discs are very long-lived. CDs from the 80's and 90's should still fiddle fine, assuming you haven't scratched them up. Same spate with DVD and Blu-ray moves, which are manufactured similarly. And, even though few are redolent of IT, publish-once BD-R HTL (High to Humbled, i.e., reflectivity, as in bright to dark) is rated to last 100 to 150 geezerhood. Why? Because the data layer is a non-vaporizable substance, arsenic opposed to the light-sensitive living thing dye used in Candle/DVD-Rx and less expensive BD-R LTH (Low To High, dark to silver).

M-Disc likewise uses a non-volatile data level, but an even major, rock-like one which is said to last x times longer than BD-R HTL. If you can't trustingness media that's rated for 1,000 years, you're pickier than I am. One note: Don't gross out prohibited when you see an M-Disc DVD+R. It's nearly transparent, but there is a data stratum present.

DoD tested

As to that thousand-year claim, the U.S. Navy will back that up. IT tested M-Disk DVD+Rs along with deposit quality Videodisk+R/RW and Videodisk-R/RW, subjecting them troika times to a 185-degree, 85-percent humidity, full-spectrum light environment for 26.25 hours. Every Videodisc unsuccessful—except the M-Discs, which suffered no discernible degradation. The Department of Defense hasn't dependable the brand-new M-Disc BD-R, but As the technology is largely the same, the results should be equally well. (We'd guess that BD-R HTL would survive as advisable.)

The only unsuccessful person point for the material used in the M-Disc information layer is oxidisation, which, accordant to Millenniata materials scientists, shouldn't be an issue for about ten millennia. Yikes. The comparative delicacy of the polycarbonate outer layer of the disc is wherefore the media lasts "only" a thousand years.

DVD and Blu-ray Compatibility

I'm not going to live a cardinal years, and so the merely matter I could test was compatibility. Millenniata was courteous enough to send on Maine an M-Disc-compatible optical writer, the Samsung/TSST SE-506CB.RSBD, for write testing. I also reliable a vintage 2006 Plextor PX-B320SA, but it didn't recognize the M-Disc BD-R media as legitimate media for writing.

You should construe with a logo something equivalent this on compatible DVD burners.

American Samoa BD-R HTL was part of the Blu-electron beam standard, and M-Disc functions such the same agency, any BD burner is physically capable of writing M-Disc BD media. But as my experience with the PX-B320SA established, if the firmware doesn't suchlike it, it won't bring off.

The logo connected the front of an physical science burner is really only for M-Disc DVDs, then only for piece of writing, as galore not-logo drives wish register it just fine. Optical maser strength must be increased beyond that ordinarily in use with CD/DVD R/RW to ablate the data bed in M-Disc DVDs, so compatible firmware mustiness be in place. Older drives could be upgraded for composition, but as there's little financial incentive, don't hold your breath.

The Selenium-506CB.RSBD burned-out flawlessly, so I took the discs it created and tried to read them using every drive I could find. M-Disc says its recordable DVDs should cost readable in 90 pct of the DVD drives installed, or being sold now. I didn't hit 90 pct, but flatbottomed though recognition could be lentissimo, the majority of the drives I tested scan M-Disc just fine. See the table below.

Make and model	Read M-Disc DVD	Read M-Disc BD-R
LG WH16N540	Yes	Yes
Asus DRW-24B1ST	No	NA
Teac DV-W516C	Atomic number 102	NA
Matshita Bachelor of Divinity-MLT UJ272	Yes	Yes
Matshita UJ8B0AW	Yes	NA
TSST SN-208FB	Yes	Atomic number 11
Teac DV-W28S-V	Yes	Sodium
Plextor PX-B320SA	Yes	Yes

Though your ancient drive might work fine, if you'ray going to commit to optical for the long haul, it might not be a bad estimate to take hold of one of the latest, sterling Blu-radiate burners. Make in for it supports triple-layer, 100GB BDXLfor little disc swapping

Non dirt-catchpenny and strange negatives

M-Disc released 4.7GB DVD discs, which are suitable for archiving documents and perhaps your most precious photos, last year. For video OR other larger files, the recently released 25GB and 100GB BD-R, as well as the soon-to-be-released (Q3) 50GB BD-R discs should take care of business.

But M-Discs aren't cheap. At retail, the DVDs are about $3, the 25GB discs about $5, the upcoming 50GB discs around $10, and the 100GB $20 or then. Just keep in intellect that this is non media that you'll have to roll over all few old age, as with CD/Videodisk R/RW or dyestuff-founded BD-R LTH. It's a one-time deal. At least until the future technological storage transfer.

M-Disc BD-R three pack.

Because the media is expensive and not as capacious equally a disk drive, you'll make to prefer what's really important and possibly divvy it up across discs. You may view this as an opportunity to clean star sign or a deal-buster.

Also, as always, optical is relatively slow: M-Disc BD discs write at a sooner pokey 4X/18MBps (6X/27MBps is the BD max), and M-Disc DVD is also 4X, or 5.28MBps. That's way off the DVD maximal, which is 16X or 21MBps. But it's a erstwhile-in-a-piece deal, so just depart your backup, belittle it, and go along about your business.

Why non online archiving?

Online archiving is certainly an option, but even in the get on of ubiquitous broadband, online memory board is relatively slow, even slower than optic in many cases. And comparatively overpriced. And unavailable when communication theory systems are downbound. You don't know who has access to the data, and you don't know how well the information center is hardback up.

Yes, I have a run of paranoia, simply IT's born of experience. In that location's naught quite equivalent knowing there's a backup in your uninjured deposit boxful or at your relatives' house. Not that you shouldn't store a copy online arsenic well.

I'd strayed from exteroception for all the habitual reasons: deficiency of speed and capacity, expense, bad discs, etc. But I'm back and fully intend to keep my most outstanding data, the clobber that tush't be replaced, archived on M-Disc. BD-R HTL would do, but just in case I DO living a chiliad years, I'll habit M-Phonograph record.
