HOT Deal on Rounded Cables - SVC

[Searchname]

Does anyone here know the actual dimensions of these cables? I know some are 24" and some are 36", but how far apart are the connectors? The IDE connector (plugs into motherboard) is 24" from the Master connector, but how far away is it from the Slave Connector? I need to know if it will do what I need it to do or not!

I'm interested in both the 24" and the 36" ATA100 rounded cable dimensions. Thanks!

17" on the ATA100 2 footers from mobo to the slave (AOC brand) and works perfectly. I redid my 3 PCs, to make it easy to poke my hands in them. Got rid of ribbon hell.

<< well i got my cables
i think the 24 inch one i ordered is defective, it keeps on giving me garbled msgs when the ide detector thing tries to read the devices hooked up to it

and its too long in my case >>



Just in case you aren't aware of it. These are "cable select" cables. If you have your device set to master it must be in the master connector or you will have issues.

First Connector (color black) = Master

Middle Connector (color Grey) = Slave

You can also set the device's shunt to "cable select" to use either connector if the device supports it.

well obviously i have the master hooked up to the master ide connection and what not but i will double check later on

got these from a retail merchant. about 2 bucks more. (and tax)They are great. look good and aren't stiff at all. much better for getting around other cables and devices. I've got a window kit on my rig so... its gotta look good. Case temp is now 2 degrees less on avrage too.

Unfortunately none. The argument that they allow more air thru to cool your CPU so that you can clock it higher is self defeating. By rounding an 80 pin ATA-66 cable, you lose the redundant ground between your data lines. Here is the electrical characteristic in question:

X (Electrical Impedence) - Can be thought of as "AC Resistance" for simplicity of explanation (but please don't say "AC Resistance", say "Impedence")

f (frequency)
C (Capacitance) - The electrical characteristic of 2 parallel conductors with an insulator between them.

The formula:

X = 1 / (2*pi*f*C)

As you can see, as the frequency goes up, the impedence goes down. The reason that ATA-66 and above cables have 80 pins/leads is that the impedence between each lead dropped to the point where cross talk between the data lines started to be a problem. By adding a redundant ground between each data line in the ribbon cable, the cross talk is grounded, instead of interferring with an adjacent data line. When you round a cable, the benefit of the redundant ground is lost due to the probability that two or more data lines will be adjacent.

Stay with your flat ribbon cables for the time being and wait for Serial-ATA comes out later this year.

This is one of the limitations of IDE drives as opposed to SCSI drives. IDE drives do not use termination resistors, whereas SCSI does. Without termination, a signal with the characteristics of an ATA-66/100 drive will reflect off the end of the cable or last drive on the cable if the cable is too long, thereby causing data corruption. 18 inches is the recommended maximum IDE cable length to prevent this reflection. This is the reason that SCSI systems require termination resistors at each end of the cable. Termination allows the SCSI cable to be much longer than the 18 inch limit of non-terminated IDE systems.

That being said, I would say that your cables are defective. They are longer than the ATA-66/100 maximum length spec.

You might be able to get away with a 24 inch cable if you are using it with an ATA-33 drive or a CDROM drive. The data transfer rate should be low enough to not be a problem.

i ordered 1 10" floppy and 2 24" silver ide's on the 17th (sunday), received thursday the 21st. so this company gets a thumbsup from me for quick turnaround.

i found the huge boot on the ends of the cables to be a bit cumbersum though. and removing them would leave exposed wires which i don't want to do. bending the regular ide cables around and out of the way of airflow works better for me in my antec 635 case. so i only using one for the dvd and cd drives and plan on getting rid of the other ide and floppy cable. great deal though, word to the original poster.

Do most newer devices allow cable select? I'd like to put my DVDROM as primary slave, but currenly won't reach since the HDD has to be on the end (master) connector. Cable select should allow me to do this. In other words, currently my cable won't reach from the mobo, up to the DVDROM, then back down the HDD cage below the 5.25" bays (Antec SX840). I've got an IBM 120GXP, Toshiba 16X DVDROM and LiteOn 24X CDRW.

How are ATA133 cables any different than ATA100 cables?


headkick,
Do the expensive IOSS RD3 Gladiator Round Cables at eksitdata fix the grounding problem?
Review.
Manuf.

Or I think maybe the QVS Rounded Internal High Performance Cables cables are expensive/better (?). They even have 35" IDE!

Here's a similar thread about rounded/'better' rounded cables.


What happens if problems do occur w/ rounded cables, just slower xfers because of having to re-read or write bad data, or permanent data corruption?

Seems I read silver rounded cables cause even more problems than standard rounded cables. True?

I got my cables today and they sent me 24" cables rather than the 18" I ordered. Great deal! btw, the blue ones I recieved were super flexible, but the red's I got were pretty stiff and I can forsee problems. Just an FYI.

 

[SupermanCK]

Anyone know if these round cables any different from the NEWEGG ones?

 

[trikster2]

Hey everyone

Thanks for the input on the silver braided cables!

Think I'll get a couple. The round cables are so nice to work with and look great.

Thanks again!

<< If you're looking for an entire set, THIS is a pretty good deal. >>




I know some people bitched/had problems with abilitywholesale.com, but I ordered two of the blue sets, they were shipped out same day as the order, I got them 3 days later. Cables are flexible, look good, and I'm happy

Moral of the story - if people bitch about something, take heed, but make your own decisions

i love companies that dont screw u on shipping...

SVC...

good company.

 

[jasonja]

I just got my cables from SVC today... I ordered them over a week ago and then they didn't show up 4 days later... I called and the order was 'lost' in the mail. SVC shipped me another set and included Arctic Alumina for free because of the delay.

They did mess up and ship me the 24" floppy cable instead of the 10".... I really only need about a 3" cable so 24" is way too much, but oh well.

cool

(AT Gods: I know, this is somewhat technical ... but I think ppl would be interesting in knowing what they're getting).

Headkick ... good post ... that's exactly what I was thinking.

I used to slice and dice my cables, especially the 50-conductor ribbon cables ... they're huge! (I have three 50-conductor cables in my rig).

I was reluctant to dice up a 80cond cable ... I dont know what it would do to the crosstalk. I haven't taken apart some of these "professional" mfg'd rounded cables, but there could be isolation between the data lines.

Has anyone taken apart a 80cond rounded cable?
