JMT 3 Ports Hidden Inside USB 3.0 to Expresscard 54mm USB3.0 Adapter Converter for Express Card Laptop Notebook PC

Decided to pull out my most favorite laptop from the closet it's sat in for a decade, and see if I can make it useable today. Installed MX Linux (The original OS was Windows XP), and everything was surprisingly useable EXCEPT the fact it only has USB 2.0, which only transfers data on this laptop at 40MB/s.So I remembered this laptop (a Precision m4300) has two different expansion slots: PC Card and Expresscard, and I wondered if there were any cards that would allow this old beast to have the more up to date USB standard.Found this Expresscard here on Amazon, and due to the reasonable price, I decided to try it out.So I slipped the card into the never-used Expresscard slot on the m4300, then put in a USB3-compliant flash drive... Amazingly, MX had the drivers already loaded, and the USB flash drive appeared...No need to use the included CD-ROM with drivers.I had tested the read and write speed on the 4300's built-in USB ports, and reached a maximum of 40MB/s. I then copied the same ISO going through this Expresscard USB3.0 card, and WOW!The copy speed is now just under 170MB/s.Granted, it's not the max speed possible with USB3, but considering this laptop has a laughably slow bus speed on the motherboard, it's surprising.So, if you have an ancient laptop with an Expresscard slot and are tired of the speeds offered by USB2, get this card. Works great, and is slim with no dongles sticking out. Almost looks like the computer came with it.Amazing...I now have a fully-useable, 16 year-old laptop thanks to this card.

I use this adapter in an old Dell Latitude E5410 laptop. Yes, all three ports deliver USB 3 (original) speeds! There is a negative that I don't believe is the fault of JMT. That would be that the card-slot clamping mechanism inside of the laptop is not super secure! I have seen this annoyance on many laptops from different manufactures. As an example, you are transferring data to or from a USB flash drive, if you accidentally touch the drive the entire adapter will pop out! Now all the data on the flash drive is corrupted!I recommend you first attach the flash drive to the adapter and then insert the adapter and USB drive into the card slot. Then make sure no one gets near it until the operation is done!

I've got an old (Win7-vintage) Acer laptop that I've switched to Linux. It had USB ports, but only a few and USB2; I wanted better speed, and since it had an ExpressCard slot this looked like a good bet for an upgrade.The good news is that this adapter is recognized by current Linux drivers; no need to install additional software. And it seems to run happily at full USB3 speed.The bad news is that the old Acer machine's BIOS boot process doesn't like it. So I need to pop this card out before booting, then insert it again to use it. Annoying, but I can live with that.The other thing to watch out for is that, since it does not firmly latch into the ExpressCard slot, you need to be careful when unplugging your USB devices or you may pull the whole card out. Which is usually not a problem, you can just shove it back in and let the drivers rediscover it. But if you had several devices plugged into it, this will of course disrupt use of the ones you weren't intending to unplug. Easy enough to deal with once you're aware of it, just keep a finger on the card while pulling the USB connection.Haven't tried it with Windows. It comes with a mini-CDROM carrying a Windows installer; I have no idea whether that is actually needed or if current versions of Windows, like Linux, with Just Work with it.The other minor gripe is that if the case near your slot is curved, one corner of the adapter may stick out a sixteenth of an inch or so. That's the price you pay for trying to squeeze three USB sockets into this space. I consider it a fully acceptable trade-off.Definitely worth the low price, if you need the additional or higher-speed USB connections.

Does not provide any power to the USB device plugged into it.Useless !Will not work with anything I tried !Will not stay plugged into laptop.Windows 7 Pro pops up message that is installed and drivers are ready.

It does give my old equipment usb 3.0 ports sometimes. 1st of all it pulls out of the pcmcia slot super easy if you dont hold it back while removing usb components. I don't always get all or any of the 3 ports reported as usb 3.0 and if I do it never stays connected very long, 20+ minutes depending on its mood. It gets hot whether usb stuff is plugged in or not... eventually shutting off the "usb 3.0 hub". But I mean... when it works, whatever ( won't ever buy from them again but that's just me)

I've gone through items like this, they really help aging PCs stay out of landfills. This is my first JMT unit and so far it's been great. The speed is as expected and this unit seems to be taking the heat of multiple USB devices without dropouts or errors. Only time will tell what lifespan this will provide (it's a race between this unit and the laptop itself, hehe).

This card works great in my 2007 Gateway gaming laptop, but the included drivers have only worked in Windows XP (Service Pack 3) so far; MS-DOS 7 and 64-bit Vista aren't playing nice with it, but on the bright side, Windows 10 already has support for it. So if you're running XP or 10, you're golden; I haven't tested any other OS's besides the ones mentioned, however.

Great way to add more ports and make an older device more useful.
