Are blu-ray drives a lot slower than dvd writers ?

[rob426]

Recently got myself a Pioneer BDR-S08 Blu-Ray drive for my PC (to replace a old pioneer dvd writer)

with the Idea to sort through my dvd data discs that I’ve made over the years, and put on blu-ray discs.

Searching through the contents of these discs, its so slow

One of these dvd’s has a folder with about 8000 tiny files in it, ranging from 6kb to 56kb total about 300mb
when I drag the folder over to the pc, is says it will take 1h 10 mins to complete.

The old dvd writer was 16x, and according to what on box the blu-ray drive came in, it can read dvd-r at 16x as well

Any Idea what the problem is

Thousands of tiny files always take longer than a single large file.

If you have a disc with 1000s of little files, it may be faster to rip an ISO of the disc, and the use WinRAR (or another program that reads ISO files), and split the files out on the HDD.

It will wear out your DVD/Blu-Ray drive to read that many small files too.

Blu-Ray drives have separate heads for DVD and for Blu-Ray.
The head used for reading or writing is based on the media inserted.

As far as reading that many files, it will take a bit on any drive, but you want to remember that Blu-rays are 3-25 times the size data-wise of a DVD and the whole disc must be read, yet the read speed is pretty much the same speed for both media.

As far as wearing out the head reading, I wouldn't worry about it, I burned over 1100 BD-DLs on my first LG Blu-Ray burner before it had a problem and that's much harder than reading. (It still burns BD-Rs without problems and reads perfectly, it just can't burn BD-DLs)

True. Packet reading/writing is very hard on drives. If you have many small files, its best to zip them first. You might want to use WinRAR for it, since it has support for recovery records. DVD's and blurays have pretty robust error correction, but better safe then sorry...

Nope. 1x Bluray (4.5MB/s) speed actually corresponds to 3.23x DVD speed. Just as 1x DVD speed corresponds to 9x CD speed. The reason for this is that blurays have a -lot- denser data tracks, thus more data can be read from the disc at the same rotation speed.

The real killer for ODD performance is head movement. If the read heads have to move (f.x. access file table, then find the file) during read, performance suffers hugely.

Thanks

Great idea making a iso. I use win8, shouldnt have a issue mounting it.
