This past week I purchased two different external enclosures for 2.5" SSDs and HDDs (one by Seagate, and one by OWC). Both enclosures appeared to be defective when used with this extension; the hard drive I tested them with wouldn't fully spin up, and the SSD would not mount (and in fact had its directory damaged in the attempt with one of the enclosures). However, plugging the enclosures directly into the USB port, instead of using this extension, had both of them operating fine.
My conjecture is that there is some small but non-negligible resistance in the power and/or ground line of this extension, which causes a voltage drop when current is drawn. For high-current devices, like hard drives or large SSDs in enclosures that may themselves draw significant current, the voltage drop can be significant enough to cause device malfunction. For low-current devices, the drop is too small to impact device operation. But I haven't done any measurements to verify this conjecture.
The bottom line is that my StarTech is defective in a way that exhibits itself only with some devices, which is a particularly nasty kind of defect. I'm retiring it. This could just be an occasional problem affecting some units, but I'm not doing the experiment of buying others to check.
UPDATE: The StarTech connectors have what looks like gold-plated contacts, which should be largely immune to corrosion. But just in case, I cleaned them with DeOxIT cleaners, and did multiple insertions, but to no avail; my external drives still failed. By the way, I noticed a bit of dust in the desktop end of the extension (and cleaned it out); it's probably worth noting that the vertical orientation means dust could be a problem.
Noting that the cable has a lifetime warranty, I contacted StarTech, describing the problem and asking what my remedy was. The response from a StarTech Technical Advisor was:
"I have done some research on this issue and have found that when it comes to external HDD’s, it is inadvisable to use an extension cable due power limitations. With the extension cable there is an immediate drop in power which also gets lower with the length of the cable as well."
This reflects poor cable design. The StarTech web site indicates this extension uses 28 AWG wire. Over a 5-foot length, drawing the USB 3.0 max current of 0.9 A, there will be a 0.3 V drop. The USB spec says the voltage drop must not exceed 0.25 V. So this cable does not meet the specification; it needs to use slightly thicker conductors.
They offered me no remedy; instead of offering a refund or a better cable, they suggested that I buy a powered StarTech hub. Note that the manufacturer's description on Amazon and on their web site says the cable is for use with "USB thumb drives or other external USB storage." There is no qualification as to what USB 3.0 compatible devices are nevertheless not compatible with this cable.
For misleading advertising and not honoring their own warranty, I've reduced my rating to 1 star.
Some reviewers complained about the ugly StarTech.com white branding/stamping on the left-hand side. It came off easily with just a wee bit of rubbing with a 'magic eraser' dabbed with acetone (nail polish remover).
Some reviewers complained that it tips over on its side from the weight of the wire. So did mine. I just twisted the wire a bit in the opposite direction to straighten out the kinks that were causing that ... and now the weight of the base is causing it to sit perfectly flat.
Some reviewers complained that there was nothing on the base of the unit to protect furniture or to keep it from sliding around. Mine was only just a bit slippery. Nevertheless, I stuck 11 of those teeny-weeny adhesive felt circles on there, the ones they sell at hardware stores and drugstores to put on the bottom of things to protect furniture. Now it slides easily but also stays exactly where I put it. Perfect-o.
Oh by the way, this StarTech unit actually works like a charm plugged into a spare port on the back of my desktop computer. No more opening the doors of the cabinet that houses my computer just to access it with my flash drive ... or to use it as a charging port for some of my other devices.
I spent a couple of hours looking at all the different types of these USB extensions Amazon had to offer and I decided this StarTech unit was the best. So far, I still think so.
Occasionally I'll use it for easy access to thumb drives or even USB headphones. But basically, if you need a small, sturdy USB extension that you want sitting on your desk or such, this is a great choice. ZERO issues of any kind with it, it does what it's supposed to and as long as I don't run into reliability issues (I've been using it on my primary computer for just over six months now) then I'll continue to recommend this.
It works great with my USB WIFI adapter - which is what I bought it for.
I have had similar products fail because they failed to use shielded cable. This isn't the case here.
I recommend this product and I could care less if the silkscreened logo scraps off - big whoop, who cares? The logo has absolutely NOTHING to do with product performance.
I used to use StarTech components back in my PC building days and I recognized the name, and so far it hasn't let me down.
