Yeah, the problem is caused by EMI/RFI that's radiated along the data path of USB 3.0 as it scrambles the data in a spread spectrum environment. It's the spread spectrum clocking that is at the root of most of the problems. I don't see masking tape factoring into a good solution. I have pondered the construct of a faraday cage like assembly encapsulating the PCIe card, aluminum tape to aid in the construction of such a homemade apparatus might be considered. Also there needs to be a heavily shielded cable and the need to move your USB 3 drive as far as possible from your computer/BT devices. A lot of RFI/EMI is escaping right at the port connector as well. It really is a poorly designed standard.
That said, BT could have been done better too. It's not very robust and has its own problems even with USB taken out of the equation.
I have had pretty good luck simply putting ferrite cores on both ends of my USB 3.0 cables. That seems to greatly improve my issues with the bluetooth magic mouse.
I got them at Amazon (the larger 7mm ones fit most of my cables best):

Just quick post. One of the ports on my Rocket U 1144C died this morning. RocketU's web site is not easily navigated. I bought mine in September of last year, so it should be covered under warranty, but they want the old card back AND you pay shipping both ways. I've started a case file with them, and I'll post up what happens.

I'm looking into buying a RocketU 1144C but it is RIDICULOUSLY priced in the Netherlands/EU. It would cost €150,- at minimum and some shops even go as far as to ask €190,- while US shops (Newegg, Amazon, BHP PhotoVideo) offer the same product at €63,-. Borderlinx (US to EU shipping service) would charge €40,- to ship, so it would be cheaper in that way, but it still feels stupid to pay so much more.
Does anyone know of a way to obtain this card in the EU at a fair pricepoint?
Alternate.de has it @ 105€. Not so bad, if you can take the VAT out of it...I'm looking into buying a RocketU 1144C but it is RIDICULOUSLY priced in the Netherlands/EU.

It's decently priced in the U.S. Considering it's specs. See if you can get the Sonnet Allegro Pro any cheaper, it has similar specs. (mainly being a 4-Controller/4-Port card).

I've been ordering them some things to my small part-time business, they don't have automatic VAT reduction system, but you can order just with e-mails. Wide variety and nice prices...
EDIT: as always compare.eu is your friend and once again alternate.de is the cheapest there...
So is there any way of stopping drives being disconnected on sleep? It's seriously annoying!
Apologies if it's answered elsewhere, I did have a search but couldn't find anything.
Look for Jettison in App Store
I ordered mine from amazon.com in the US & they shipped to UK. The price including shipping & taxes & customs (all paid up front) was half what the card would have cost from amazon.co.uk. I am sure that they will ship to the netherlands too.I'm looking into buying a RocketU 1144C but it is RIDICULOUSLY priced in the Netherlands/EU.

so question,
Let's say I buy either the RocketU 1144C or the Allegro Pro 4-Port USB 3. They both have dedicated controllers for each USB 3 port. But I want to get a USB 3 Hub. Will the bandwidth be limited to 5Gb/s for my USB 3 hard drives connected to the USB Hub? or will I be able to take advantage of the other controllers using one USB 3 Hub?
In short: Yes. No.
Explanation:
That would be limited to the capabilities of the USB3.0 port the hub is connected to. So a 4 port USB3.0 hub would divide the 5.0Gb/s over the connected devices. Given that one device could use more throughput than the other (mouse/keyboard vs USB SSD/HDD) this would be distributed accordingly.

yeah that makes sense. I have a music studio desk (image attached) and the front panel makes it easy to access the front USB ports of the Mac Pro. I use portable USB 3.0 HDDs that have short cables so it's easier to plug in from the front USB 2.0. Maybe a solution for me would be to get USB 3 extension cables.Here's the issue. If you get a USB 3 hub. It plugs into 1 port of you PCIe card and therefore only has access to the bandwidth of a single port. It then divides that bandwidth amongst the USB ports being used on the HUB.
Cosider the ports on the back of the PCIe card as the HUB, instead of using an external HUB. Most USB devices don't really benefit from the additional bandwidth of USB 3.0. Plug your slower devices into your USB 2.0 ports/Hubs, and leave the USB 3.0 for highspeed devices like harddrives/SSDs. If you need more USB 3.0 ports for storage devices, then you have 2 choices. Either use the USB 3.0 Hub and devide the bandwidth of one port (assuming you only use ne Hub), or install a second PCIe card. I was running 2 4-Port cards for a while and they worked perfectly for me.
To be honest, I think I may just go ahead and get the Sonnet Allegro over the RocketU due to stability. Flaky is not going to cut it for me. Plus I like the sound of the ability to charge devices with the Allegro.They're both great cards but the Sonnet Pro cost quite a bit more. The RocketU is a little faster but not enough to make a big deal over. I've had one drive (out of more than I care to count) that is flakey on the RocketU. The issue is really with the drive rather than the PCIe card, but the Sonnet Allegro Pro does handle the drive better than the RocketU.
Given that the RocketU is less expensive and a little faster as well, it's hard to justify the additional expence of the Sonnet. The one thing I really like about the Sonnet is that it's using FrescoLogic controllers.
Also, for your use case, I do recommend you get some high quality, shielded cables long enough to reach your drives. Shy away from extension cables and use direct cabling to the drive. An extension cable just presents another connection/splice point for RFI/EMI leakage or other connection issues.
What's the difference between FrescoLogic controller and the one from the RocketU? which company has better customer support?I don't think you can go wrong with either card. I didn't mean to say the RocketU was flaky. It's not at all. The drive enclosure was flaky and spazzed out on every USB interface card I owned. It just happened to work better on this particular card. To date I've never had a single issue with the RocketU 1144C.
