Can i RAID 2 HDD that has same capacity but different brand?
For example, WD Blue 640Gb and Seagate 640Gb?

yes you can but usually ppl raid the same brand/model/type..

cause of performance.. firmware differences as it might cause some performance degradation...

Ok thanks
Will the performance lower than single HDD if i RAID it this way?

I don't think it'll lower than single HDD speed unless there's something wrong with your RAID controller, otherwise you should use software RAID for most compatibility, hardware RAID is sometimes* a bit choosy.

I know 1 way that you no need to post your HDD to Singapore for RMA. PM me for details.

i'm selling new unit -> 1TB 3.5" SATA internal HDD Spinpoint F3 103SJ~ anyone interested?~

Can sata2 HDD be use on sata1, secondly can i get the sata2 speed if use on sata1.tq

You can go ahead and buy the SATA 2 HDD, but since your mobo does not support SATA 2, the HDD will run only at SATA 1 (150Mb/s) performance level. Although the point remains that since no HDD is actually able to sustain a transfer rate of 300Mb/s or even 150Mb/s all the time, you may not notice much difference.

It is very similar to plugging a USB 2.0 device into a USB 1.1 port. Windows will warn you that the device may not function upto its potential, but it doesnt stop working or anything.

Here is a page I found that explains the jumper settings. Look at the OPT1 setting that allows SATA 2 drives to run on SATA 1 ports.

Thanks a lot, second question does it need to set the jumper becos i forget its actually 2.5 hdd not 3.5hdd, thirdly can sata1 detect 500gb hd

Hi,

Which is better between the 2 below if price is same:

1. Buffalo Drive Station LB series with TurboPC 1.5TB
2. Samsung G3 1.5Tb

TQ for your opinion.

Which RAID? RAID-0,1 or 0+1?

RAID performance can degrade because:

1. Fast HDD become slow because it's pair has slower performance.

2. Some scenario which make RAID-0 awfully slower than single harddisk such as 4 HDD in RAID-0 copies a large file into itself. The HDD controller have to split the data into 4 and send the data back 4 times. Imagine how many jobs the controller has to do.

I've tried 4XRAID-0 before, and its works best to transfer file to other RAID pairs than into itself.

i have a question for anyone using single large harddisk such as 2TB or at least 1.5TB.

Do you have problem like when you wake up your PC from sleep, the large 2TB HDD will be disconnected because of its slow startup. When I wake up my PC from sleep, only the large HDD missing from My Computer. To wake it, I have to choose Sleep again and wake it up instantly. If fails, I need to restart completely.

Any method to solve this? Thanks

Are your HDDs RAIDed and then got disconnected when waking up?

Not in RAID mode. Other maller HDD wake up successfully. Only the 2TB Seagate barracuda slow to wake up
