Pros: Easy to use, light weight. Master/slave jumper, activity LED, 4 assembly hole. Medium soldering quality. Work fast with my old laptop :) The BIOS detect it like HDD :)

Cons: Must cut off the pin #20 ( like in the preview picture), because in this position no hole in the 44pin female connector in my laptop. Maybe this pin blocked to prevent the drive to be plugged in the wrong direction.

Other Thoughts: Advisbale switch off the swap file under windows xp because frequent write cycle corrupt the CF card. Maybe need more physical memory to work XP without swap file (~ 1GB enough to me for normal operation ).

Bottomline: Buy it and make SSD drive!

Pros: Works with CF, microdrives, and CF readers (mine was a type II CF card that reads SD cards).
The microdrive I was using does not fully support the PC-Card interface (it's a Seagate ST650211CF drive with firmware version 3.04; one of my CF reader will refuse to read it), but it still could be used with this adapter.

Cons: On certain connectors, there's 1 pin blocked to prevent the drive to be plugged in the wrong way. This pin is there on this, so I had to remove it by bending it repeatedly.
The 44-pin connector is soldered so that the protruding ends on the soldered side comes out on the bottom when compared to 2.5" drives. On SKU 8821 and a laptop of mine, there's no space allowance on the bottom, so if I just use it directly, it would scratch the surface. I had to file it off to prevent scratching and to prevent it from tilting up. Wish they designed it so the PCB is on the top of the CF card.

Other Thoughts: Wish there were better packaging than just bubble wrap. The pins came slightly bent. A little cardboard would help.

Bottomline: Great way to get a SSD into laptops if you've figured out how to minimize writes from your OS. I used it to replace a noisy HDD with a microdrive (which is more quiet). Also used it in USB enclosures. Definately useful.

Pros: Easy to install, very compatible, no modification needed

Cons: Hard to line up pins...use a flashlight.

Other Thoughts: I installed a 233x 8 GB CF card, plugged it into my X40 (upside down first...then other way second)turned on the HD and nothing worked. I took it out and put it into an IDE adapter and used Windows XP to format the CF card. I first tried NTFS and that did not work for me. The tried FAT 32 and Windows XP Professional installed perfect. It works like a normal HD but faster and with less battery draw. I can hardly wait to try a 16 or 32 GB 300X CF card when the price comes down. I still need to figure out how to install the HD cover so it stays tight.

Bottomline: For less than $3 you can build your own SSD.

Pros: I used this adapter with a 2GB CF flash on an old laptop and installed XP. It booted ok (have to format the Card to NTFS).
It is completely quiet compared to the moving arm of a HDD.

Cons: The card can easily be installed the wrong way especially if your laptop interface does not have pin blocked.
The adapter is easy to install if your hdd location is underneath the laptop but pain if you need to push it from the side or front of the laptop. Once installed, it stays in place.

Other Thoughts: Maybe they could include some kind of plastic tool to assist installing this card on tight places.

Bottomline: very cheap solution if you want to have a CF card as harddrive.
