PERC 5/i RAID Card: Tips and Benchmarks - Page 624

What application are you benching with?

For me HD Tune reports speeds on the Perc 6i that are much slower than onboard ICH Raid. I am talking less than 150 MB/S average for the Perc, and 250 for the ICH. I have screen shots.

Crystal Mark on the other hand shows almost 270+ across all tests on the Perc. Besides that, I don't need a benchmark to show me my system if faster on the Perc so I am inclined to think something is wrong with HD Tune.

This is on Circa 2008 640GB WD Caviar Black with TLER ON.

Before you go flashing firmwares, I would recommend using some other synthetic benchmarks.

Try to increase Block Size in HD Tune benchmark options to 8MB.

nice first post - few realise what HD Tune benchmarks actually show, and even fewer have a clue what the input options actually mean.

Hi; I have some questions about the Dell Perc 6/i; I tried to read... but 624 pages are very long read...

I'm planning to use it in my HTPC with Windows 7/8 - MCE/XBMC; and it's going to storage movies & series (large files) in RAID5 mode;

AMD Quad Core Phenom2
Dell Perc 6/i E2K-UCP-61-(B)
4x Hitachi Deskstar 5K3000

Some questions:
What stripe size do you recommend?
Does this card run well on Windows 8 x64?
Anyone flashed the Perc 6/i with the LSI 8888elp firmware?
In the LSI site, there is a newer signed driver 5.5 (6.505.5.0) with Windows 8 support. I think I can mod the INF file to add the Perc6/i. Anyone tested it?

Maybe this questions were asked... thanks for your patience; and sorry about my poor english.

Bye!

Can someone give me some tips on how to do a benchmark test on my Perc 6i? Since I got it installed a few days ago I noticed when I copy files from my RAID array (over gigabit LAN) that the speed is initially very good 80/90 MB/s but once it gets closer to the end of the file it slows to a crawl (4-5 MB/s) and it hangs with the progress bar at 100% for a good 30 seconds before it says it's completed.

I'll reply to you both at once since it's a similar subject. HD Tune has a trial version on their website for free, crystalmark is free. There's a trial version of SiSoft Sandra that does hard drive benchmarks, there's also the older program I like called HDTach, I think you can get a trial version of AIDA64 which has a built in benchmark reader thing. Try lots of different programs and if most of them say about the same thing, then you know what your speed is.

For me when I first had my PERC 5/i I put windows on a single hard drive so I could fiddle with my raid array and delete/re-create it as often as I needed to find the optimal configuration. I had 4 x 7200 rpm SATA drives (8mb buffer) in raid-5 on my Dell PERC 5/i, with 128kb stripe size (the dell firmware only allows stripes that high), and it was reporting 160 - 165 MB/sec reads with 60 MB/sec writes in every program I listed above (I tested them all). I then flashed to the LSI firmware and rebooted and instantly it was testing at 270 - 285 MB/sec. I cleared the array and re-created it with 256kb stripe size (the new lsi firmware allowed that) and reads went up to 320 - 325 MB/sec, and writes at 240 - 260 MB/sec.

I have hit the warm-boot bug a few times, but as I've said previously, it doesn't effect me.

*Edited*
Disregard the below section, I thought 5k3000 was a 3TB drive. Thanks Sean!
Sadly to say, the PERC6 does not officially (and therefore probably doesn't at all) support hard drives *Larger Than* 2 terabytes. those 3 TB Hitachi drives likely won't work at all. From what I recall, when I hooked up some 3 TB drives to do a RAID1 while migrating data, they didn't work at all and I had to use the onboard RAID controller. You need an H200/H700 for >2 TB Drive support.

*Edited* The next section stands
To answer a couple of your questions,
Run the largest stripe size possible if it is for large media files
It runs well in Windows 7 x64, but can't speak for Windows 8. I would stick with 7 for a stable file server
I've actually read through the whole thread, and no one talked about Windows 8 or the LSI firmware for the Perc6. The Dell cards are customized LSI cards, so for stability I would stick with the Dell firmware. If you have good backups and don't mind taking a risk, you could try the firmware yourself and report back to the thread so everyone else knows!

Quick question, don't mean to derail the thread any, but as another user stated 600 pages is hard to read through. I currently have the 5/i running stock firmware on my Ubuntu Server box. If I flash the LSI firmware, with the card as it is right now, will I lose my current array setup?

I will have a backup regardless, but want to know if I'll have more work cut out for me (i.e. restoring all my files).

You are indeed correct, that was my laziness for assuming 5k3000 was a 3 TB drive. Original post edited!
