3TB+ Array on Add In PCI-E Board on Non 3TB+ BIOS?

post #1 of 5
Thread Starter 
Im thinking of upgrading my NAS Storage over to a 6TB (3TB*2) on a PCI-E Raid 0 Card.

But... my current NAS box is a Dell 3100C system I believe, and its donkeys years old... Im assuming this BIOS wouldnt support anything over 3TB but as its on a Add-In board wouldnt that eliminate the problem?

Yes, I am aware that running a RAID0 can cause me to loose my data, if I hold off on it till HDD prices have dropped some more then I should be able to go 3*3TB for RAID5.

Current:
Dell 3100C
P4 @ 3ghz
1gb RAM
1 * 1gb Edimax NIC
Cheap Silicon Image PCI-E RAID card (2*500gb)
80gb SATA HDD -onboard boot
Win08 R2

why not start with just independent disks or RAID 1? Unless you have more than 3TB of data right now i think it's a little risky to put 2 3TB disks together like that

I agree with not putting 6TB of data on a RAID 0, not worth it imo but it's your data to prioritize.

But, to answer your question, yes a new RAID controller would let you run the 3TB drives as long as it supports them. Your OS would then see a 6TB drive and the controller has its own BIOS, bypassing the onboard BIOS for your drives.

Ive never had a RAID0 array fail though, even with disks that are now over 2000 days uptime and they have been hammered for at least the first three years?

Like I said, I want RAID5 ideally, but im down to my last 30gb in my current system, 3*3TB just costs a bomb right now.

Are the bigger disks more prone to fail than say some 320gb sammy f1's or 500gb deskstars - cause mine seem bulletproof?

Glad to know if I get a card that sports 3TB+ then I wont need a new box.

There is the theory that if you do run RAID 0 with 2 drives you will reduce the load on that single disk which, in theory, should extend the life of the drive. But if you were to fill them both up, it obviously wouldn't make a difference.

People say that the more platters you have the more of a chance there is to fail. I dont really agree with that but HDDs can and do fail, its very uncommon that new ones do, but it does happen. I haven't had one die on me yet but I saw it happen a dozen times at work when I was a tech so I personally wouldn't risk 3+TB of my data on a RAID 0 just because one has never died on me. That's just my advice to you, loosing all of your data can really suck, I've seen it happen too many times.
