Haven't posted much since your forum helped me through an upgrade on my desktop. It has been performing great, but I would like to upgrade to USB 3.0. I checked Newegg and was a bit confused. They have USB 3.0 cards with external slots, internal slots and a combination. Do the internal connections convert my existing USB 2.0 slots to 3.0? If not, what do they do? Also, the reviews of many of the cards, particularly SYBA, were harsh. Do you have any recommendations?


Also, what are your thoughts on SSD cache drives like Corsair's Accelerator or others now on the market. Corsair's product had some pretty mixed reviews.

As always, thanks for your help. I've sent so many people to your site for help and have heard nothing but good things back from them.

It would help if you linked the actual card your looking at, but my suspicion is the internal connector is the connector. that you can plug your case USB ports into, as opposed to a traditional USB ports. You will notice if your case has any USB ports, that they plug into your motherboard. Well, I would suspect that the internal USB your looking at is the 19 pin header, so that you can plug additiona USB 3.0 ports from your case to that card. Some cards do actually have an internal USB port, for reasons unknown to me, perhaps for using a jumpdrive for a permanent storage device, without it hanging out the back of the computer.

Actually a lot of card readers/front panels use/used the USB3 male connectors. Bad as it sounds they were designed to run the cables through the case, out through the rear slot, and into a rear motherboard USB3 port. Some of the USB3 cards have the connectors internal just for this purpose, to simlify routing. The 19 pin header didn't get standardized until later, and it is only recently that you can finally get cases and motherboards that both have the proper pin connectors.

Sorry. Down with a bad back and couldn't get back to you. You helped me rebuild this computer a couple years ago but I can't find the link. You also had a link that I.D.ed my system for you. I don't know where to find it. But, I have an HP w/ an AMD 925, 4 GB DDR3 RAM, 500 GB HD and run Windows 7 (64 bit). Also, I installed a Nvidia GeForce 2 MX 4600 series graphics card.


I looked at a lot of cards at Newegg, but I don't really understand the differences or the internal bit and I'm not sure I understand your posts. Most seemed to mention 19 pin headers but I'm not sure what that means to me if I install a card. And, is it even worth it? From what I read the transfer rates were much faster.

Also, any opinions on the SSD cache drives like the Corsair Accelerator or the similiar products from OCZ?

You can't convert it, but you can add a USB 3.0 PCIe slot if your motherboard supports it.

Hi, I'll put it this way. If you want SSD performance use a SSD drive not a cache drive. There is a reason for those bad reviews.

As for USB3 I had mixed results except for the Western Digital USB3 card which shows up as a NEC USB3 in the device manager. It is a Solid performer. You need a good card since the only reason for usb3 as I see it is to speed up external drives. A card that will keep connecting and disconnecting the drive is asking for data corruption.

Nothing converts the existing USB2 to USB3. Also be prepared to buy USB3 cables to use with the USB3 ports. The device connector is different.

There are a few front panel devices that have a plug that plugs into a existing USB port and that would be why the cards may have a internal port. Providing a Internal port usually reduces the usable external port count however.

Good Luck
Roger

P.S. I have stopped buying any USB2 external drives and have standardized on USB3 only. Usually 2TB as a sweet spot for size and price.
