Something looks wrong... the benches should be more downward sloping.

Are you using Direct I/O or Cached I/O?

Direct I/O, should i change it?

edit:
how are my numbers so far? my main use will be 4*F1 raid 5 so the raid 0 tests are just for info

which reminds me, i'm finished... can't test no more, will continue tomorrow

edit 2:
is it me or are my numbers low? where did i go wrong?

I just wanted to write everyone in here that proceeded to give a big thank you for labouring through this process. Just got my Perc 5i installed today on a ASUS P5E3 Deluxe (Intel X38), reflashed to LSI and service manager nicely recognizing that yes Virginia, there's a santa claus providing RAID cards at a half decent price.

FYI, I did find these guys on ebay for small fans / heat sinks - I haven't mounted it yet, but eyeballing the connectors it should fit fine if someone is looking for one of the older heat sink / fan combinations that don't take up alot of room, since the older style of clamps are becoming harder to find.

http://cgi.ebay.ca/ws/eBayISAPI.dll?...m=120373756284

Without fan, it sits around 1 1/8" tall, with fan a little under 2".

Edit: bah! didn't fit!

ebaying I go again

just letting you all know the kingston registered ECC ram works great.

Hi there, I've been eying up one of these cards on ebay, the auction finishes in the morning. Please could someone offer some advice on this card.

Currently I have a P5Q-E motherboard with a RAID5 array setup on the onboard RAID with 6x500GB Drives. Would buying this card give me better performance? Having used hardware SCSI raid cards in the past on previous hardware I would say it should improve. But in my system I have a ATI Radeon 4870 1GB and of course that PCI-e slot is running at 16x currently, if I plug this card in, the graphics card will be reduced to 8x (limitation of the P45 chipset apparantly, I know this is the case for other motherboards too) is this a big loss, is there going to be any performance loss on my games? Or is it just going to be the same?

Please advise, would be much appreciated, thanks!

EDIT: also does having one of these cards prevent the HDD activity led on the PC case from lighting up or does it still work?

(Had to do it)

Well, it looks like my 750GB drive addition to my RAID 5 array worked correctly! My computer went to sleep in the middle of it too, I'm quite impressed that it didn't fail.

The HD activity light only applies to hard drives plugged directly into your motherboard, so yes, it will disable it for any hard drives plugged into the PERC 5/i.

You should be fine at x8 for your video card, expecially if you have PCI Express 2.0. I don't believe any video cards max this out yet.

Using a dedicated card such as this one should drastically increase the performance of your RAID array.

Also, make sure that it comes with the battery. These are like $40 by themselves.

I'm sorry if this has already been brought up. This thread is quite long and I tried search, but didn't see any results.

Has anyone had an experience with running two perc 5/is in 1 pc. Also if this is possible I was wondering if anyone had any suggestions on a good motherboard for that setup. Thanks in advance.
post #1339 of 7190
So, I'm confused now. I added the 4th drive to my RAID 5 and it says it worked correctly. In the RAID manager, it shows the array with 4x 750GB drives with optimal status and 2.1TB of storage. When I look in windows, it is only recognizing 1.3 TB, Windows is obviously not recognizing the last drive. Why not?

Edit: Never mind. It made an unallocated space at the end with 750GB of drive. Problem solved.

What does everyone use for their HDtune settings under options when they are doing their benchmark tests?
