RAID controller $24 + shipping

[BadNewsBears]

Whats raid 5. I have run raids 0 om my machine and raid 1 on the server. What the hells 5?

 

[merlink]

Hey.. I have (2) Maxtor 120GB w/2MB (cache), and (1) WD 120GB 8MB (cache). What's the best RAID setup I could do utilizing all of these drives? Could I do a RAID 5, since I have 3 drives?

Raid 5 is striping with parity.
i believe you need at least 3 drives to run a raid 5

 

[TechShopper]

Too good of a deal.

I got this for my new Epox motherboard (8RDA) cause I was upgrading from a board with built in RAID. Nforce2 boards RAIDless, when I ordered.

You can download this program File to benchmark your access speed.

I ordered from Newegg and it came with a CD. You'll want to download the latest drivers from Silicon Image, not the outdated one's on the Koutech CD/website, onto a floppy. Reload Windows as bootdisk, and press F6 to load RAID drivers from your floppy during fresh install.

Here are my benchmarcks using a RAID 0 and Atto benchmark (I linked it above) with this card:
2x40 Gb IDE IBMs @7500 RPMs

That's correct, but you don't get added storage space of a RAID 0 array, and the array is as large as the smallest in the array. You'll also need a 4-channel hardware RAID card for RAID 5, as the parity calculations aren't generally supported by softRAID controllers with no dedicated mathCPU. Nice thing about RAID 5 is that if one drive fails, the array can rebuild itself (while fully functional) b/c of the parity data stored on the 3rd drive.

These cards are based on the Sil680 softRAID controller; I had the one from Newegg for those of you asking. Its an excellent performer, but it used up quite a few CPU cycles in some apps and also didn't have functional LED headers. The one linked in the original post does. The results I had were very good, but I went with a 3ware Escalade 7000-2 hardware RAID card, and have been very pleased with it. I get read and writes in the 70mbps to 90mbps range and it uses significantly less CPU utilization.

Is anyone using this card for drives >137BG? I'm thinking of doing a dual WD2000JB (@200GB) RAID 1 setup, but the WD page talks about needing 48-bit addressing for drives > 137GB, and even ships with a special Promise (non-RAID) Ultra ATA card. Will these big drives work with this Koutech RAID card?

Thanks!

For a quick overview of different RAID levels, look here
You ned a minimum of 3 drives for a RAID-5 Array. The total array is reduced by 1 drive. (eg: if you use 3 drives of 80GB each, the RAID 5 array will be 2x80=160GB. If you use 5 drives of 80GB each, the arrray will be 4x80=320GB.)

Thanks for the link.

[diablonhn]

there's a lot of misconceptions going around about raid...

raid 0: fastest you can get, but effectively divides your MTTF in half

raid 1: increases your read speed, decreases your access times, but write speed is slowed down just a little, very good with small I/O, large I/O not improved, 50% space utilization

raid 2: slow like heck, slightly better in large I/O than raid 1, but terrible in small I/O, 71% space utilization

raid 3: drastic improvement over raid 2, beats raid 1 in large I/O, but still horrible in small I/O, 91% space utilization

raid 4: a little better than raid 3, 91% space utilization

raid 5: night and day difference above raid 2,3, and 4, very fast large I/O and a small I/O that is just behind that of raid 1, the parity is spread across all disks, 91% space utilization

terms:
small I/O - data is located on only one disk drive
large I/O - data is spread across multiple drives

Good summary. I've always thought it was "independant" disks not "inexpensive"

[diablonhn]

now since practically all disk drives are of the same size, people are now using the term "independent"

Is everyone happy with this controller? I'd order it, but it bothers me if they are advertising the model with IDE activity jumpers and shipping the cheaper one. Is that still the case?

Nevermind, I just ordered the better model from NewEgg. It was $33 with free FedEx shipping.

I posted on this earlier, but I returned 2 of the PIRFLEX 133's from NE b/c they don't have functional LED headers, just 2 very weak LEDs that aren't visible even with a case window (they face down and are very dim). Just an FYI for those who need to see a LED indicator to know their HDDs are spinning. Card performance is quite excellent though, comes very close to a Highpoint RocketRAID 133 card that costs 2.5x as much.

[addragyn]

Anyone with the money for a four-drive RAID0 and controller owes it to himself to try a Cheetah 15k.3 first.

I absolutely concur.

$27 and free shipping from Newegg.
Wonderful deal...people jump on this

4xRAID0 is insane, it's faster than SCSI hands down, gives you tremendous storage (even using boring 40GB HDDs) but you have to be concerned about corruption of a disk or failure of a disk.

I'll accept that challenge. See below. In a price vs performance conversation I would agree with you, but I will smoke almost anyone in raw disk performance.

Before you scream that it says ghost 2001, look down under solutions where it says 2003 and below....

Now if anyone does know how to clone a hardware array, I would love to know how....

If it's mirrored, pull one of the drives, replace, store the first one in a safe location. Replace as needed.

Chiz,

I saw your posts, which was why I ordered that specific item from NewEgg instead of Neutron. Maybe I'm confused. You said the card in the original post has a functional IDE activity LED jumper. That card is IOFLEX-PIR133 (the green PCB with black drive connectors). But people said they were actually receiving the IO-PIR133 (black PCB with blue and white drive connectors) from Neutron. So I assumed you meant that the green PCB was the card to get. Didn't you thank Kevman for telling you that J2 is for the HD LED?

Yah, I thought it was, but it didn't work :| Upon further inspection, I saw that J1 has jumper solder points, but no jumpers Not sure what Koutech was thinking, maybe they thought internal LEDs were better than a header for an external LED indicator. You might have better luck, but its definitely a different card, and I didn't realize that Kevman and the others that ordered in this post actually had a different card until after I received my 2nd board. If you don't mind the possibility of not having an external LED header, the IOFLEX is an excellent card (based on the Sil680) for the price.

Hmm...well I found a posting in the newsgroups where someone with the IOFLEX said that their case HDD LED flashes via the motherboard when there is RAID activity on the card. Is that the case? Should I have ordered the cheaper model? What exactly is the difference between these cards?

I doubt that's the case, as a RAID controller isn't recognized as a standard IDE drive, its a standalone AIB in both the BIOS and in Windows. I'm not even sure its possible for that data to be sent via the PCI bus through the mainboard and output via the mobo's LED header. I could be wrong, but I did have the case header attached to the mobo, not to see if the RAID card would show activity thru the mobo header, but actually to use it as the LED indicator for my stand-alone IDE drives attached to the mobo's IDE headers. I have my RAID controller attached to my CoolMod and my case LED attached to my IDE mobo LED.

I'm not sure what performance difference there is between the black and green one is, so I'm not sure. By the time I went thru the second one, I had already been eyeing the 3ware 7000-2. Newegg was great about RMA'ing and I told them I'd like to go with the 3ware at $125 since I already had ~$60 tied up in 2 RAID cards. It performed very well, but CPU utilization was still a bit high. The 3ware is awesome though, excellent card if you are only looking for RAID 0 or RAID 1 with 2 disk drives.
