9750 no raid vs raid 0

With Raid you get one "RAID 0 SCSI Disk Device" in drive section.

I got strange problems with SATA Raid0 and Daemon4 on my 9860 - crackling HD noises that can´t be good and sporadic reboots while boot process. 4.03 on my 9750 and XP64 works flawlessly. Anyway I have too
much fear to try it on my 32bit Windows.

The raid contoller on the 9750 works with Sata HDs only. If you got PATA/IDE, you are SOL and have what you have. You would have to buy new HDs to go Raid 0.

To answer your question I got the Sata/Raid 0 and love it.

Check your bios and see if they show up individually on Master 1 and Master 1 for the last 2 "IDE" Channels on the system. If they do that is the Sata port (notice there is no "Master 2" Or Slave Option for these last 2 entries.

Daemon tools in either event should work great with the 9750v and would never cause your "physical HD" to crackle that would be more along the lines of a hardware related issue and not software any "physical" noise would be. The sporatic reboots however could be an issue with DT but I have not ever had that (run the tools on my laptop - desktop - server box without issues) I would recommend if anyone is looking to use dtools to get the latest and greatest version however that uses the iSCSI as their virtual driver.

"The raid contoller on the 9750 works with Sata HDs only. If you got PATA/IDE, you are SOL and have what you have. You would have to buy new HDs to go Raid 0."

I was just stating (not sure if you knew it already) but to check your bios and you'll see an: IDE Channel 2 Master and an IDE Channel 3 Master - These are technically the Sata Ports and I have no reason to present why they are labeled as IDE ports - Which may be why yours shows up as an EIDE Device when plugged in.
(That was for your comment of) "One thing I noticed was that with no raid the hard drives show up in device manager under the ide controller."

I was just stating that you should check your bios to make sure it's on IDE Channel 2 or IDE Channel 3 - Both Show as Master (notice no slave). Sorry for the confusion.

Software RAID combo (RAID1,RAID0,Standalone and LVM]

I would never want to use RAID0. If you loose just a tiny bit of one disk, you will loose the whole RAID0 disk. RAID0 is the best way to reduce the MTBF (Mean Time Before Failre) of your disk-subsystem.

I've decided to stick with a two separate disk config, and use software raid at the operating system level to improve the redundancy of the system. The operating system is spliced into a few different partitions, most are done in RAID1, temporary files are kept on a RAID0, the swap files are dedicated partitions on each disks, and the rest of the spare space is lumped together under LVM (equivalent to a RAID0 config).

Now, I've done this config under Linux, but you should be able to do the same kind of config under Windows XP. I've added below my config, and in parathensis the RAID1 or LVM status of each partition. Enjoy

My NP9750 comes tomorrow, but I think I may have a problem... I am a noob when it comes to understanding RAID, at least I was until i starting reading a lot of the great info that I've found on this board.

I ordered my 9750 with Raid1. I understand that it's for data redundancy, but that it has slower performance than Raid 0. My primary use for this laptop will be gaming, so I'm worried that I've incorrectly configured it.

Would Raid1 be ok for gaming (mostly eve online and a few others) or should I switch to Raid0 and if so, is it even possible to switch to raid0?

Here's the spec's:

7. Primary Hard Drive = 80GB 7,200rpm Hard Drive SATA 8. 2nd Hard Drive = 80GB 7,200rpm Hard Drive SATA 9. RAID Setting = RAID 1 enabled (Data Mirror, 2nd and Primary HDD)

thanks in advance for any help or advice!!

Raid Zero is slower for writes; however should be a bit quicker for reads. I'd leave it alone - you will have "mirror" protection. If you decide to "switch" you will need to reinstall everything.
