And just because a particular media speed is mentioned, doesn't mean you can buy it. Your local store will be filled with the most inferior media, in terms of speed. http://en.wikipedia.org/wiki/Blu_ray Paul |

Does anyone use Blue Ray burners for backups ? I was wondering how long it takes to burn DVDs compared to standard DVDs. Andy I have a SATA Pioneer Blu-Ray and I am unable to find COTS Blu-Ray media. Therefore I just use standard DVDRW +/- media. -- Dave Multi-AV Scanning Tool - http://multi-av.thespykiller.co.uk http://www.pctipp.ch/downloads/dl/35905.asp |

I'm considering buying a few blu-ray disks of a couple of different types but I was amazed when I found the many different densities/space/prices, so I'm approaching it rather carefully and only plan to try a couple of different kinds if I can get low enough quantities. Want a laugh? Quill.com carries only one blu-ray disc; a double-layer hi-density 50 Gig disc with for $60.00 ! Nuh, uh! They don't even indicate what speed they are capable of. My opticals are all capable of high-revs and blu-ray, but ... woof! I'll get a couple thumbs for less than that cost! HTH, Twayne` |

There's a large number of types and spaces avalable for varying prices. My optical drives are capable of blu-ray and the software's there to support it, but ... . As for how long it takes, who cares, really? I'd hope for at least 8x but what's the big deal? For the capacity of one blu-ray you'd still have to burn multiple standard DVDs of DVD-RDLs, so I'd expect them to take longer depending. HTH, Twayne` |

HTH, Twayne` From the recording speed table here... http://en.wikipedia.org/wiki/Blu_ray ******* Of the BD-RE on Newegg, they're 2X speed (9MB/sec). This is the speed you'd get on a re-usable disc. 2X, single layer, 45 minutes, 25GB The BR-R, you can find 6X speed, with just one pack of 10X speed (and that one has no reviews). So I'd expect to be buying 6X, of the "burn once" variety. 6X, single layer, 15 minutes, 25GB 10X, single layer, 9 minutes, 25GB And that means 15 minutes per 25GB, or ten hours to backup a 1TB hard drive (sitting around, changing media etc). Or a lot longer, if you walk away from the machine, and load in a new blank when wandering by. I suppose you could buy ten drives, and cut down the backup time to one hour. At least you'd be busy flipping discs the whole time. To make that approach practical, you might be better off making ISO images first, then doing the burning of the ISOs as a separate step. The 6X write speed is 27MB/sec, still within USB2 range. If you did manage to find 10X BD-R to experiment with, that runs 45MB/sec and then you'd want a SATA connection to the optical drive. Or USB3, if you could find a working solution (I don't know if there are problems doing ATAPI over USB3 or not). If you did take my joking suggestion, to use ten drives in parallel, it would be best to connect them via SATA. If using USB, you'd need to spend more time finding a workable solution. Ten drives at 27MB/sec each, is a lot of bandwidth for USB. Some experiments would be required, some hair loss etc. My motherboard only has two USB2 controller logic blocks on it, to support all the ports, so that means 120MB/sec absolute max aggregate bandwidth (and less than that in practice). And I don't know if anyone makes a USB3 to USB2 hub or not (rate changer with no bandwidth limitations). Connecting up the ten optical drives, and finding space to put them, would just be a PITA.

HTH, Twayne` I read that consumer Blue Ray disks are very sensitive to light, scratches, and oxygen as compared to CDs. It only takes one day in sunlight and they become coasters. The DVD movies are pressed in the DVD, so they last much longer. I'll stick to CDs and pen drives. |

HTH, Twayne` From the recording speed table here... http://en.wikipedia.org/wiki/Blu_ray ******* I don't know why I never thought of Wikipedia; dumb! Thanks. Going Inline: .... Well, I back up to Terabyte external drives via USB but it all works in the background plus doesn incrementals wth a full backup on the first day of each month. One external is for Drives C & D, the other for the other three drives. If I keep a history of more than 4 backups, I shortly run out of room and need to let the backup program delete some of them; it does an interestingly good job of keeping incrementals from old backups and attaching them to backups that won't be removed. And yes, it compresses files also. Every three to six months I copy the most recent backups to DVD-RDL (8.5 Gig) and that too happens in the background. It's no big job to toss in another DVD every time one fills up and the tray ejects as I go about my daily work. It's no big sacrifice to toss in a new DVD here & there as I work. My real goal is to cut down on the number of DVDs it takes for a complete transfer to DVDs, and not a time issue; I'm used to that and know better than to NOT do backups, having learned the hard way. The other half of the issue is to not go broke buying blu-rays; another 1 or 2 terabyte drive isn't the answer either because only DVDs are a semi-permanent storage soluton. Thanks for the Wikipedia link. .... Paul |

Andy I haven't yet had one of my terabyte drives indicate defrag is over a few percent and it's usually zero. A good backup program does very well at keeping fragmentation down. As for 16 Gig being all you need, apparently you don't keep any history of your backups and only do one at a time. But that said, you're very frugal if you can back everything up in 16 Gig. That's not bad, just very unusual. So DVD storage should be a snap for you. -- Regards, Tom` |

After reading about the shorter life of CD-RW which I am using, I may backup using CD-Rs. |

But it burns DVD's quite fast, just as well as any standard DVD burner, 16X DVD speed, 12X BD speed. Yousuf Khan |
