What are BD pc drives using? - Blu-ray Forum

Plan B · 03-26-2006, 11:26 PM

Hi, this is my first post, however I have a question perhaps someone can answer for me. When BD drives for pc's bcome more wide spread, what interface will they be using, IDE or SATA? I'm in the process of building a new pc and want to know if should leave one of the four 300mbs SATA connectors open for future upgrading to BD? Thanks in advance.

both interfaces can be used, the choice is up to the manufacturer.
i think the first ones announced were ide though. optical drives are sticking to it for now.
of course there will be more "exceptions" than with dvd drives this time, as sata is getting popular and boards with more than 6 ports become common.
i think you shouldn't worry about the lack of ports yet - an ide drive should still be easy to find, and if not, a pci sata controller will still solve your problem

Hold on... Isn't PCI's bandwith something like 33Mb/s? And isn't IDE's 100mb/s? Then SATA being 150mb/s? So if all those above transfers speeds are right (which i'm sure SOMEONE will find something wrong because I'm not completely sure of PCI or IDE myself) wouldn't having a PCI to IDE be a bottleneck on the burner and the burner require underrun protection? Because from the thread I started, the info I got from an ADMIN (so this must be true) is that 1x on a BD burner will be 36mb/s, and first generation will be 2x. And also from an admin i heard they'd have 12x burners by 2007, so that would be a speed of 432mb/s. But then again, SATAII can only transfer at 300mb/s (right?) so would it need 2 data connectors and be a pain to connect to your computer if you rely on air cooling, and then 3 cords just to one device would cut off airflow. Especially if tthey make the first generation IDE, that better come with a rounded cable about the same size as an SATA cable because the IDE ribbion wire will just get in the way of all other system components.
If anyone can correct me on the data rates of these interfaces, please tell me so i can re-correct my theory.
Wait... Can anyone also tell me the average sustained data rate for any of those interfaces?

That's not what I said, I said expect at least 4x in 2007 and 12x as the potential maximum speed sometime in the future (no time specified). When exactly they plan to come out with 6x, 8x and 12x drives I have no idea as there's been no public statements made about this yet (too early for that).

Also, just because I'm an admin at the forum doesn't mean I can't be wrong about things, so don't take what I say as a universal truth without questioning it. Things could change and what I've read/heard doesn't necessarily always become true.

Plan B, what mobo do u have? (Curious to know, though this may be totally irrelevant)

I'm using the intel D945Pvs. I've got 3 hard drives, 2 two running raid 0. I'm in the middle of creating the pilot for a cartoon, in HD of course, and I'm afraid of using my last SATA port on the mobo for a fourth hard drive. I'm presonally hoping they start using the SATA ports.

While many first-generation drives will use IDE, the Philips and BenQ drives should use SATA at least. Also, it's still unclear what the Sony drive will use.

No longer a fan boy of intels so i don't remember anything about their line of products anymore. But I have a feeling its like my DFI, and has another chip for SATA1 (150Mb/s). If this is the case, leave either an IDE or SATAI open. If you don't have SATAI on your mobo, then leave open either an IDE or SATAII. But the chip for the SATAII might not be backwards-compatible and support the SATA the drive will use. So in the end, if you have normal SATA (150Mb/s) you're safe. If you don't then I advise getting an IDE cable of your choosing for your new IDE BD drive. (soon to come :P)
Or ya can get a PCI card with SATA plugs and use that but i don't know if that's made or whatever you would prefer. If i get spare time, I'll do a little research on your board and see if I can help you out on that question a bit more.

I picked up a 4 port SATA card from New Egg for $25 and it works fine.

BTW, PCI has a greater bandwidth than 33 MBps cos it is wider than 8 bits (32 bits wide iirc so 4 bytes per transaction, not one).

Cheers!
