Some Hard disk questions

Hey Guys,

couple of questions. First of all, is it possible to un partion a drive while keeping data intact and problem free? Second of all is there a limit to how many drives you should have in a system?

Also is it possible to set the drives up as a raid system without disrupting data, is raid system reccomended for internal drives if one is acting as a session drive, the other sound library and the other system etc ?

And last, is it possible to tell if a drive is sata2 or sata3 by just looking at the drive?



Thanks guys!!

Im a PC repair tech when not recording so I feel the need to chime in here lol. You cannot have data on a drive that has no partition. To "unpartition" a drive would be the equivalent of erasing it.

The only limit to internal drive is the number of sata connections you have (you can even add sata pci cards, but then you would be splitting the pci bus between added drives and you interface)

Having DAW/OS on one drive and audio recorded to another is a basic necessity, RAID is a backup method that creates redundancy in your disks if one should fail (google raid0) if you can afford the extra drives it's very good to do.

To figure out sata2 or sata3 youll have to reference the part number in the mfg website, some discs might reference the speed on the top label but its not likely.

Oh also in regard to raid. I wouldnt worry about it for your os drive so long as you keep copies of all your licenses on hand, mostly useful for those irreplacable project files and takes. But to create a raid array the disk partition table has to be rewritten a specific way, and it can't be done without erasing data. (Be careful if you find any programs claiming they can, i wouldnt trust them to not corrupt the data. You are better off getting an external drive and doing a temporary backup.)

No. You'll have to backup the data first. For an OS, you will need to create a backup image, not just copy data.

Practically no. You can add SATA/RAID controllers as long as you have PCIe slots.

Quote:

RAID 1 (redundancy), yes. RAID 0 and RAID 5 require striping, which will erase all data on all drives.

Never mix system with audio, unless you have an SSD which additonally can be used to stream samples. You could use a RAID 0 or RAID 5 for all audio tasks, but it does not really do much for audio nowadays compared to single drives..

Search the model in the internet.

But that is not an issue since audio uses minimal bandwidth.

RAID 0 is not redundancy, it is extra bandwidth and the opposite of redundancy. If one drive fails, ALL data on BOTH drives is lost. RAID 1 is full redundancy and is highly recommended for anyone earning his bread and butter with audio, at least to record to and have the current projects located (with a daily backup of course). With SSDs, be careful, since RAID 1 is not supported by most controllers/SSD combos, and can be a nightmare very easily.

Correct for RAID 0/5/6/10, but RAID 1 can be created without losing data. Also, most controllers can dissolve RAID 1 without losing data, despite the warning you will get.

Thanks for the info guys, ive connected the hard drives i needed to for now, i Have system, Projects and then my sound library. And also a back up drive in a hot swappable bay that goes in front where the cd drives are.

But now im out of sata. I have a pci card with 2 sata connections on on old computer this will allow me hook up sata from externals, id like to connect that also and maybe 1 more drive, im looking at the best way to do it, its hard to believe my old computer had more sata ports available.. I need some help figuring it out lol

Thanks for the detailed answers!

But do you need more SATA ports? It sounds like you're set up.

Well id like to connect the pci card to allow me connect externals via sata for faster transfers and id like to get one more drive in i know when i buy the latest Eastwest librarys im going to need the space.

Any suggestions, this is the mobo GIGABYTE - Motherboard - Socket 1155 - GA-PH67A-UD3-B3 (rev. 1.1)

Thanks!

So looks like ill have to get a PCIe Expansion card, should i get sata3 even if im not using SSD, i guess its good to futureproof as it is backwards compatible. Also is there a huge difference between a PCIe X1 or x4. Which would be recommended?

Also if i had 2 drives for projects would it be good to set those up as raid in the system?

cheers guys!!
