If you plan to use it (copy, burn, whatever) while performing other intensive tasks SCSI may work better, thanks to much lower CPU utilization and not interfering with your IDE read-writes. Otherwise, 32x IDE will perform much better.
In my case, four-drive RAID 5 was roughly 30% slower than three-drive RAID 0. (10k SCSI-160)
I use software RAID though (Win 2k server). I heard that RAID controller can improve significantly performance.
In your case (for IDE RAID 5 you need controller anyway) you may have better score.
I have four 10k/u160 drives on one 32bit channel with no problem. But, when I was reinstalling drives into enclosure I pushed one pin on 68pin connector half way in. I didn't bend it, just pushed it in with plug. It forced the drive into 40MB mode, but just this one. It took me an hour to find...
Try downloading new drivers and load it when setup asks for additional drivers.
I have win2k on IDE drive and Tekram 390U2W for CDRW and scanner. 2k didn't see my drives till I reinstalled a driver.
<< Most cable modem co's that charged $35 a month for 1+mb down and 256 up, were LOSING money, a lot of money, because bandwidth is expensive. I agree with it. They are doing it so they can become profitable, broadband won't take off until its profitable. Honestly if you want unlimited...
How about going Athlon way? You can get Abit NV7m which is microATX board with nForce chipset, integrated nVidia graphics on a level of GF2MX, sound with spdif out, lan.
You still have AGP and three PCI for some future upgrades. It's cheap ($121), suports DDR and cheaper CPU.
BTW, case...
You might be right that problem with my DVD drive is not being ATA - but being "cheapo".
Still CPU utilization is of some importance since mp encoder uses everything available, up to 100%
I just run some tests on my CD drives, to determine the best configuration for a giant task of transforming my CD library into MP3.
Drives are: 4 months old DVD 16x ATA (supposedly 40xCD), 3 years old SCSI CD 24x, 6 months old SCSI-2 CD-RW 12/10/32.
I put first handy game CD and run Sandra...
Tyan's Thunder K7 S2462, dual MP with on-board U160 although I don't think it's zero-RAID. Which means if you want to run some serious RAID you better buy mobo without SCSI controller, as most RAID controllers are already equipped with SCSI controller.
S2462 is unfortunately $400+.
My...
SCSI rocks in RAID. Sandra on my 3xU160 10k Fujitsus in RAID 0 went to 65,000. Unfortunately since I added fourth one for RAID5 (software, still not enough money for controller) it dropped to 46,000. They're in my domain/application server. The other three machines are very happy with IDE...
Do you have any non-LVD devices on the same channel with HD? (CDR, DVD etc.)?
Do you have appropriate cooling, airflow? (I had problem with drive showing 40 instead of 160 until I got proper airflow in my file server)
Give us some more info on your box.
Two of four run 24/7. One is a server.
The other is my information and media center.
If I watch a movie and want to check some info on actor's bio, or get some facts checked while following History channel documentary, or how to get to some address in town, or just watch same music videos (ones...
It happened to me some 5-6 years ago. NEC warranty covered repair (even when breaking pins is evidently users fault), as long as as cable was not messed with. You didn't say how old is your monitor (most have 3 yrs warranty). If it's under warranty check with manufacturer, maybe they'll fix...
One more thing:
Hardware in HK stores costs about the same as on Internet here. Actually if you have time and patience, you can find some coupon/rebate/sale opportunities less available out there. Just make sure PS supports both 110/220V and 50/60MHz. I never had problem with ThinkPads, just...
I have laptop with P2/366MHz/192MB RAM and:

I'm afraid that with SCSI you have to go with new and expensive or none.
Spending money for single U2W+cheapo controller is a waste, since you'll get same performance and 5x more storage space with 120G WD/8MB cache.
If you want performance gain over IDE especially RAIDed 0, you need to go for...
Don't flame me to hard, please.
I have 6 SCSI drives inside my home server, 4x10k/U160 and 2x10k/U2W all LVD, SCSI CD and CD-RW.
I absolutely don't regert it. I still need to point out to JJ650 how much cost is involved in building SCSI system.
And for gaming, some DVD ripping and maybe some DV...
<< scsi is better, one fast 15 000 rpm drive with good cache will blow the sh!t out of any IDE system you could imagine. >>
You can check e.g at storagereview.com that on most non-syntetic benchmarks new IDE drive will stay within 10% from your 15k SCSI.
Only in server enviroment SCSI stans...
If this is standalone machine don't waste your money on SCSI.
SCSI shines on servers.
If you still have burning in your wallet, how much can you spend on your disk subsystem?
Some advice:
1. Make sure you have enough storage space to do backups (at least weekly) of you RAID 0 arrays (you may...
I had similar problem, using Morpheus for simultaneous download of 20+ files to the PC which is at the same time a server for home network. It brought IDE almost to a crawl, moving 100MB file from one HD to the other (on the same PC) was taking 5-7 min. I went for SCSI and now I'm happy...
I put 4 10k/18G U160 drives into RAID5 array. Using 2k server and software RAID. Formatting of the array seems very slow (~5% per hour). Can someone verify if this is normal? Or maybe I should stop the process and look for a problem?
Reconsider.
1) Unless you already own one CPU, you'll have to spend somewhere between $250+ (pair of P3/850) and $400+ (pair of P3/1000).
2) Your board supports only 100MHz bus which eliminates chance of running much faster, Coppermine based CPUs.
If you run miltithreaded applications and can...
Consider dual Tuallatin P3-S /512k cache board. It'll perform at the level of single P4.
Interleaved PC133 SDRAM is comparable in speed with DDR or RDRAM yet much cheaper.
There are some excellent mobos like SuperMicro P3TDER and P3TDE6-G or Tyan Thunder HeSl-T.
Boards aren't cheap but will...
Buying is better when:
- it's the first computer person owns (I bought a system in 1992 and since then through countless upgrades it multiplied into 6 under three roofs).
- it's dramatic upgrade ( I plan to upgrade my server - currently P3/1GHz on i820 to new Jackson enabled Xeon <preferably...
<< Isnt the HD the slowest part of a computer that is slowing it down or no? >>
Yes and not. HD is much slower than RAM or Video, but it doesn't work all the time. You load your game or application saving maybe 5-10 seconds with faster drive, then it runs mostly from RAM. Even intense video...
After reading this long tread I don't think you need to spend $$ for 15k SCSI. You won't notice much of a difference. If you have burning wallet, buy two 18G instead of one 36G and put them into RAID 0 array (you'll need RAID controller or Win2k Server). Difference will be huge. I still...
Thanks bigbigsavings.
I plan to spend next year vacations in Spain and I'm already collecting tools to improve myself above what Europeans think of standard American tourist. I bought Spanish with Michael Thomas 8CD set from Amazon, but I certainly will use other sources, especially if...

It's my first order from these guys, can't say anything about their reliability.

I'm looking for hw to built compact pc for the kitchen. It has to be mobo fitting slim case, thus mATX. It has to have enough graphic power to run TV feed and some video, it has to have AC3 output to play MP3s through liv.rm amp. It has to have 100mb LAN to get those feeds from the server...
If you don't do multiple simultaneous read/writes (you don't plan to use it for server),
and don't need extreme speeds (video streams etc.) go with IDE drives.
You can leave your controller for SCSI CD-RW and DVD-R drives, so those won't tax your CPU like their IDE counterparts and don't clog...
For mirror (RAID 1) you need pair of drives of preferably comparable capacity. I have RAID 5 of four U160 drives for data and applications, but you need at least 3 drives for RAID 5 and you get capacity of smallest drive x (number of drives -1). So, if your friend can afford buying two more...
Adaptec 2100S (32MB SDRAM) $350
Top of the line would be 64bit/66MHz stuff, but you will need at least 3 very fast drives on one channel to saturate 32bit PCI.
If you can afford it go for it. I switched to SCSI couple months ago. I've done multiple (20-30) simultaneous downloads, besides that PC is my file and domain server for other 3 at home. With all this simultaneous accesses my 80GB/7200rpm IDE drive was crawling. I considered IDE RAID for a...
You have good points neuralfx. I guess we would have to know more about kittycat's network. I just spoke from my own experience. I have just 4 workstations attached to a single PIII/1GHz (i820) with 512MB RDRAM and RAID 5 of SCSI160 drives and it often chokes (doesn't crush, just gets really...
You didn't specify your budget.
Consider dual Tuallatin PIII ($440 for a pair of 1.13GHz/512kB cache or $520 for a pair of 1.26GHz)
mobo with ServerWorks HE-SL chipset (e.g. SuperMicro P3TDER or Tyan Thunder HE-sl, $450+) extremely stable, uses interleaved ECC SDRAM up to 4GB/s from four-way...
Don't do it or buy another 40GB/100 !!!
Each drive in RAID array works in capacity of the smallest one and with speed of the slowest one.
