I purchased 40, mine were not gold plated. looks like tin although I cannot confirm that. They do fit very snugly and are the cheapest I have found that are decent quality. Great to fix communication errors on the cheap. Buy better cables if it's mission critical. I actually run these on 2 of my small servers replacing cables I paid a lot more for locally.
They appear to be. But it don't say if they are or not, so I'm not 100%sure. I'm using about 8 of them and have had no issues so far. They are nice and beefy. They are shielded with 26 AWG wire. I highly recommend them.
Every one clicked into their connectors snugly and replacement with them eliminated communication errors some other sata cables produced. Be aware the tabs for the click-lock may be close together on some motherboard sata ports. For the price unbeatable will buy more.
Exactly what they are. Blue. 18" and locking latches. What I found funny though. When you measure for 18", you forget sometimes to measure an extra amount for slack. Next time I'll go with the 24" as a minimum length. 18" becomes about 16" in usable length, the way i see it.
