    Motherboard integrated RAID5 performance

    Hi Vorpel, I'd like the array to hold all my everyday activities. It includes OS partitions with swap file, 30-50G mp3s, video files 500M-2G, disk images 100M-5G, etc. All I want is faster disk performance AND safety from drive disasters. The perfect solution would be a Promise SuperTrak 8350 with multiple logical drives (RAID0 for OS, RAID5 for data), but that and the disks cost about my monthly salary. I hardly can miss a whole month. If I use mobo RAID5, the price of the controller is saved. I just wanted to know how slower the cheaper solution is. I'll post when I decide. Good luck, Peter and thaks.

    Motherboard integrated RAID5 performance

    Looking at these and summing up all the infos I have I got some questions left : 1. Out of the first review, it seems neither chipset integrated RAID5 solutions use the system processor for parity calculation, but the chipset itself does it. 'cos CPU usage is about 2-4%. Is this really true ? It's hard to believe ... 2. Is writing so incredibly slow with addon hardware RAID5 cards compared to reading also ? 3. With sofware RAID5 (in case of chipsets), write performance equals to processor speed, and CPU is always 100% used during disk writes, isn't it ? 4. I suppose while reading in RAID5, parity data isn't used to optimize drive head movement, is it ? I mean that the controller reads the parity chunk instead of one of the data chunks of a row of data and calculates the missing data out of parity in order to minimize head movement. They don't do it, do they ? Thanks for the answers in advance. Cheers, Peter

    Motherboard integrated RAID5 performance

    Trinary : That's the thing I've not taken into account yet. Thanks. But I want RAID5 because : 1. I want fault tolerance. 2. Don't wanna lose 250-300G of capacity. It's 50% of the remaining with 4 disks. 3. It's enough to have 1 spare drive. In RAID0+1 or 1+0, two drives can only fail in a special combination without data loss. If two random drives fail, data is probably lost. If I'd have 8 disks, I probably would consider 1+0, but that case no chipset solution is acceptable. Adariel : YESSSSS, those links helped a lot ! Although I'm a bit frustrated 'cos it seems neither chipset integrated solutions use the system processor to calculate parity, but starving with it on they own. What a stupid approach ! THX for all. Cheers, Peter

    Motherboard integrated RAID5 performance

    It's incredible ! Nobody is interested in RAID5 ! I'm sad.
  5. nVidia corporation probably disabled the correct usage of an ATI card in their chipset. Or, the X300 is not capable of running without 16 lanes. Both blames the corresponding manufacturers.
  6. I always recommend Seagate over Maxtor because it's far more reliable. I have a 10 years old 540MB Seagate drive that runs Linux 24/365 days without any kind of problem. Seagate's 5 year warranty is worth the extra cost. It's not more than 10%. I've seen tons of dead HDDs during my 6-year practice in computer repairing stores. Seagate was the least frequent candidate. In your place I would wait a few months until prices degrade a bit, or buy two 300G drives, its about the same price than one 400G drive, and 500G drives are even more expensive. I've looked up the prices in the most popular price comparison site in my country, but the same probably also applies to the US. The best parts are always more expensive than better performing all around the computer hardware industry, not just in the HDD segment. Cheers, Peter
  7. If you want to make sure it's okay, you must determine your Power Supply Unit (PSU) brand and type. Open the case, look at the top left corner, it's usually written there on a sticker. Your mobo is okay, especially if it has 3 years warranty as most ASUS boards have. But the PSU is more important.
  8. I disagree with that. Go to Tom's Hardware and search for NCQ. They say it's good. SUSTAINED transfer rates can be slower with NCQ, but only marginally, but your computer almost NEVER reads or writes contiguously to the drive during everyday use. If the drive gets a lot of small read/write requests, like Windows does, NCQ boosts the overall performance. NCQ is a technology that was developed by leading drive manufacturers. It is absolutely sure that they wouldn't have been investing in it if it was useless. Every is a weighty word. Try 'almost all' instead.
  9. You can safely switch on your PC this way, provided you have a good quality power supply. Poor quality power supply units may fail from this kind of usage. What brand of PSU do you have ? It also depends on the motherboard model. Not all mobos switch on from a proper shutdown & power outage.
  10. Why do you want to disable NCQ ?

    Is a 2nd HDD worth it?

    Honu, don't you think that this question would have been better placed before the actual purchase of the far most expensive HDD available in the market ? You didn't mention your mobo type, but it probably supports RAID0. You could have been achieving the same performance with another 160G Seagate drive put into a RAID array for a quarter of the WD's price.
  12. Hello everybody, For a long time, I was wondering about a safe and also fast storage solution that's protected against drive failures. The solution of choice would be RAID5. Since I'm not a company but an individual, high-priced server solutions were out of scope. In the last months, several motherboards came out with RAID5 capable controller chips integrated on them. As my current everyday used config is almost 3 years old (Socket 462), it is an attractive alternative for me to change the whole platform also. I know that RAID5 needs parity calculation on the fly, and in case of motherboard integrated controllers, this task is done by the main processor, as it's also the case with cheap standalone controller cards. This solution is less-performing and more resource-consuming by its nature. But the question is : how much less performing ? I want the RAID5 solution having the best price/performance ratio. I've searched the net a lot for integrated mobo RAID5 reviews, found none. I'm especially interested in the performance of the following chipset solutions : - nVidia 430 SouthBridge - ULI 1575 SB, 1597 NB - ATI's still-not-released new SB chip SB600 - Intel Matrix Storage (ICH6R/ICH7R) If anyone has info or can link to sites having RAID5 performance comparisons regarding these chipsets, please post that here. Cheers, Peter

    Is Norton Utilities Dead?

    Btw, what was the best edition of NU ever ? 3.0 ? 4.0 ? I suspect that the last edition for Win9x that included Norton CrashGuard, and had a symbol of a cog was the best featured one for Win9x. When 2000/XP came, did they already miss features even from the 1st edition for NT, or was NU evolvig the right way for a time ? Which was the best edition for 2000/XP ? Did they ever wrote a powerful defrag engine for NTFS ? Did they ever wrote a powerful direct disk editing tool for NTFS, like DiskEdit for FAT(32) ? IF ANYONE HAVE THESE INFOS, PLEASE POST ! Cheers, Peter

    Is Norton Utilities Dead?

    Hello all frustrated enthusiasts, I must highly agree with the topic starter's point of view. Now it's clear. Until now, I was just suspecting this, but from now on, you made me sure. Norton Utilities were one of the five PC softwares that I loved best, since I first pressed a key 15 years ago. My all-time-favourites were NDD and DiskEdit in the DOS and Win9x ages. I've repaired a LOT of logically broken drives using them either at home and in the firm. I also used SpeeDisk very effectively. I even used SpeeDisk on DOS 6.22 to see the file arrangement on a floppy last week !!! Symantec made me very-very-very disappointed and frustrated by deliberately killing Norton Utilities. Probably anybody wonders the reason why they did this. It's a suicide. It's a crime. I feel exactly the same about it than loosing a best friend, having data loss on HDD, being stolen a valuable property, etc. WE HAVE LOST SOMETHING THAT WE LOVED. From now on, where the hell computer softwares are evolving ? What direction does this kind of things and other things like TCPA lead ? If something ever will cause Windows to be beaten from the throne of home PC OSes, this will be the one. Curiously looking forward the consequences : Peter Borosnyay (30) Pécs, Hungary
