How fast are DVD±R drives going to get?

[Chaotic42]

A lot of us remember the days of the 2x CD-R drives for $350 and the ads for blisteringly fast 6x CD-ROM drives. 16x DVD±R drives with 2.4x DL capabilities are everywhere these days.

My question is (if anyone has any idea), how fast will these things get? Are we going to see 52x Dual Layer DVD±R drives in the future? Is 16x good enough? I need to do a little backing up (I currently just back up to another hard drive), and I'm interested in getting a DVD drive, but I can wait if new drives are set to come out.

probably 16x max..which is over 22 MB/s. most HDs can only sustain 20-30 MB/s. also Blue-ray or HD burners are coming out.

16x is the max dvd media can spin

also, though the NEC drives are very popular, DL won't live much longer

i'd rather get 2x4.7GB discs than 1 dual layer discs

plus, HD-DVD and Blu-Ray are going to outdo the storage capacity of DL

Anandtech had an article stating that DVD drives will max out at 16x because companies are shifting focus to their hd-dvd/Blu-ray drives.

Newer hardrives can reach 50 - 75 megs according to storagereview.com

There is a difference between "reaching" a certain transfer rate and "sustaining" it. Thankfully, the sustained rates are improving with time as well.

Its more a matter of centripical force than the ability of the hard drive to keep the cache full.
Ive heard some pretty intence stories of what its like to have a CD exload in a high speed drive.

I remember an external sony SCSI 4xCD drive at the sweet price of $1600

80MB/s burst and 40MB/s sustained is what I get reported for my 80GB Western Digital.
Most seem to not be at least 40MB/s sustained.

Happened to me - 16x/40x Pioneer DVD drive blew up my Giants: Citizen Kabuto Disc (don't remember 1 or 2). Spins up like normal, then a loud WHACK from the drive.

And, speaking of exploding CD's:
Best exploding CD (and amazing science experiment) site on the web.

IF the dvds are spun at a a higher rate than 16x than they will explode . Higher transfer rates and writing speeds aren't sustainble at speeds higher than 16x and that's why manufacturers are switching to bluray and hddvd.

 

[NightCrawler]

WB99 Disk/Read Transfer Rate - Begin- The sequential transfer rate attained by the outermost zones in the hard disk. The figure typically represents the highest sustained transfer rate a drive delivers.

WB99 Disk/Read Transfer Rate - End- The sequential transfer rate attained by the innermost zones in the hard disk. The figure typically represents the lowest sustained transfer rate a drive delivers.

The outer- and inner-zone scores of the WD740GD rest at 71.8 MB/sec and 53.8 MB/sec respectively.

just read up on 16x DVD specs...the max speed has to do more with the RPM of the dvd at 16x, which is a little over 10K RPM. its about the same RPM when burning a CD at 52x.

They are switching to bluray to get more data on a disc.

dont you think that the dvd+-rw will be replaced like cdr,

for instance, when cdr's first came out - wow, 650MEG - and we can write to them.....

within 18 months, using bluray, or whatever, there are gonna be new technology drives backward compatible with the dvd's that are out now.
These will be faster [4x v 48x], pack more data on [like 650MB v 700MB cd's], and will eventually come down to the same price equivalent as cdrw/dvdrw are now.
wont they?

 

[Tostada]

Like others are essentially saying, DVD-Rs won't get faster because the media is not rated to spin over about 10,000 RPM. DVD-ROMs peaked at 16X a long time ago.

I didn't read this AT article you ppl are talking about, but anybody who thinks the purpose of Blu-Ray is to increase transfer speeds is confused.

This statement is totally absurd. The primary market of DL is the full-quality direct-copy piracy of movies.
DL will be extremely widespread once it breaks the $5 barrier. Every idiot in the world will have a DVD-RW and a NetFlix subscription.

Blu-Ray will have almost no effect on the success of DVD+R DL. DVD movies are here now. 98% of them have two layers. You can buy a DL burner for $65.

I'd love to have some kind of DVD replacement where I can burn HDTV and fit a ton of data, but that's just not coming to market any time soon.
