SATA II and SATA 6 WD Raptor Drives and SATA II Raid Controler Card
Posted on 2011-09-12
Please Help. I posted this over an hour ago in Tom's Hardware but I need to get some answers before I have to leave.
I have the following situation.
I have a 3 drive set up. They are WD Raptor 300GB in RAID 0 for speed. I am using an areca ARC-1210 PCI-Express x8 SATA II (3.0Gb/s) Controller Card. One of the drives failed. I removed the drive and rebuilt the raid Raid on 2 drives. I could tell the difference between 2 and 3 drives.
All 3 of the WD drives are SATA III. The card seems to be SATA II.
I called WD and complained. They sent me an RMA. While at work i thought 4 drives in RAID 0 might be even faster so I looked at the Model number on the WD RMA email and ordered a 4th drive using that model number.
I got the RMA and the new drive today. Guess what. The RMA and new drive are SATA 6. So now i have a delima. I have 2 SATA III drives AND 2 SATA 6 drives.
My raid card appears to be SATA II.
I am looking for performance. I want speed. Can all 4 of these drives live in raid 0 ok?
Will the faster ones drop down to SATA III speed?
Should I buy2 more SATA 6 drives?
Should I look for a new raid card?
I was told this raid card was very good and much better then the on board cards and i dished out like $300 for it.
My motherboard is an MSI Eclispe SLI but I just got an ASUS Rampage III and will be swapping thee out. Both have on board raid. I think ASUS has SATA III raid card. Should I now us the on board raid?
I am looking for FAST boot times.
FAST decompression of very large files.
And FAST compression of very large files. I do a lot of video rendering as well.
