RAID 1 Question

I have a WD1600JS and received a WD1600JD in the mail today. The seller sent the wrong hard drive! The JD is 1.5GB/s and the JS is 3GB/s. I was wondering if i run them in RAID 1 right now when i take out the JD and replace it with a JS when i receive my replacement will it run at 3GB/s?
 
you can't tell the difference in 1.5 vs 3.0 anyway.. in theory raid 1 compliant controller can rebuild.. but you always run into problem like select the wrong source (pick new blank drive and replicate that to your old drive) and wipe out your data ...
 
It applies to the usable size. In a mirror situation, no more than the smallest drive size can be mirrored. The resulting mirrored RAID 1 array is 1.5 GB. If you replace the 1.5 with another 3.0, then you will have to re-image the new 3.0, but the array will then be 3.0 GB.

 
dude u paid for a SATA 300 right? you should demand that they send you a new one in replacement (at the same time you send yours in) of the SATA 150 version so that when you RMA your hardware, you will get it sooner. tell them you are in need of running a RAID 1 array, and that it would only be fair as a consumer through the company. if they don't do it, talk to the manager and complain, but be nice.

damn shipping and handling, who gets it right these days?

there is a diff. in SATA300 if you're a diehard speed freak, for the other post. the SATA300 has better technology and obviously transfers at higher rates.

your fastest drive will be as fast as the slowest drive in the array, FYI.
 
If the drives are the same size it should work properly, you should be able to use a jumper on the JS to set it to 1.5GB/s SATA1 mode. It sounds like the seller sent you the wrong drive so request a new one, it's only fair.

www.barefeats.com has benchmark tests showing that's not the case - that 3GB/s drives can be faster for large small transfer jobs.
