bloody SATA connectors (electrical)!

i've come across connection issues
with my (admittedly limited) use
of SATA drives, both data and power,
most recently power

what an aggrevation!

are others seeing this?

SATA connectors require precise manufacturing in order to
work well. Many cheaper ones just have too high tolerances.
Buy quality and you should be fine.

It's a script that awakens periodically, triggered by ATA, IDE, an so on. Or
self-appointed SCSI preacher without a life. "I'm a righteous one: I don't
use no bloody ATA".

I use SATA drives - Have a lot of experience with them. I have seen
some issues with them being fragile. It's critical that the cable be
exactly straight coming out of the drive. I have seen quite a few
broken cable ends where the side (edge) of the connector is broken.
That weakens the connector so the top and bottom spread and the spring
tension if the pins won't make adequate contact with the gold on the
drive PCB. Have only seen one case where the cable was bad without any
visual damage. I believe that case was a result of the cable being
stressed at 90 degrees over too short a radius.

Overall, I like SATA cables. They don't interfere with the airflow in
the chassis (as do the PATA cables.

Yes, I think there is a special place in hell for the idiot who designed
the SATA connectors on the disk. I've given up, and when I build a PC I
install a drive housing that occupies 3x5.25" bays and gives me four hot
plug SATA bugs. Because of the way this is designed I've not had a
single problem with power or drive connectors since doing this. The one
I use is:

Hmm. I hope they improved their manufacturing. I had two of
these with a PCB manufaactured shoddily enough, that I got CRC
errors on some of the disks. These errors were severe
enough that disks dropped out of the RAID they were in and
vanished vcompletely when connecting them directly. Took
me a week to debug and then I just threw this trash out.

I was also quite unimpressed with the cooling.

I've got one that's been going about a year now, the other is more
recent. So far I've not had any problems with them. But there are other
products out there, maybe there are some better ones.

A bit of Blu Tack around the connectors does wonders.

Maybe the just fixed that production quality issue.

If you really must use SATA you ought to try Supermicro chasis and
backplanes as they are the best on the market.

I highly doubt it. Some Super Glue and two drywall screws help hold the
drives in place with these substandard pieces of garbage.

I recently read a report from Google, and it basically comes down to, that
SATA drives aren't necessarily worse than SCSI or FC drives. Here's

That's what you get if you buy drives intended for backplane use.
Buy the ons intended for desktop cases, those with regular Molex power plug.

How strange when below you just say they work utterly fine when used as intended.

Gee, what a surprise: you are using them as intended.

Sadly, even these have problems occasionally. I have a few of the
Supermicro 5 drive units and I had to send back one of them. We did
have one SCA connector fail a few years ago too. As for SATA vs. SCSI,
of course there are instances when SCSI is the only way to go (15K
drives for instance) but more often than not it is too limiting to go
with SCSI. We couldn't do a lot of what we do if we had to pay SCSI
prices. SATA has proven to be very reliable (except for one array that
used Maxtor drives... that was a nightmare but no data was lost and it
had nothing to do with SATA, just Maxtor). With about 90 SATA drives in
operation over the last year, we have had zero downtime due to the RAID
arrays and only one array that needed to failover to a spare drive.
With about 20 SCSI drives we had two drives that failed in the last
year. To be fair, the SCSI drives are much older than the SATA drives.
