Blue ray burners

Does anyone use Blue Ray burners for backups ?
I was wondering how long it takes to burn DVDs compared to standard DVDs.

See the "Recording Speed" table.
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.

I have a SATA Pioneer Blu-Ray and I am unable to find
COTS Blu-Ray media.
Therefore I just use standard DVDRW +/- media.

Yeah, I use the DVD RDL's; Stll only 8.5 Gig, but better than 4.7.
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!

I don't use them, but an considering it. 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.

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.

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.

I can't imagine many folks using much space on a 1 Tb drive.

It must take forever to do a chkdsk or defrag on it.

I am using only 16 Gb out of a 225 Gb drive.

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.

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.

Thanks for the good info.

I don't have a second drive on my laptop.

I use a batch file to back up changes.

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

I got such a burner, but I've not yet even used a Blu-Ray blank in it
yet. But it burns DVD's quite fast, just as well as any standard DVD
burner, 16X DVD speed, 12X BD speed.
