-Flashing blue light on adapter when hard drive is being accessed. -USB 3.0 speed! (this ensures your hard drive transfers go as fast as they possibly can. my old Seagate 200GB IDE did about 60MB/s where as if that same drive was on a USB 2 connection it would be limited to about 30MB/s since that's the limit of the USB 2 interface. with USB 3 on the other hand, since it's faster than any hard drives available, you don't have to worry about any speed handicaps based on the USB 3 interface unlike USB 2 where you will experience a 30MB/s limit on file transfers. to state the obvious... in order to use this devices USB 3 speed you need to have a USB 3 port on your computer which the easiest way to find these is they typically are 'blue' in color.) -Price (at $20 it's a solid buy) -Seems durable enough, does not feel cheap. on/off switch seems like it will last and connecting this device to a hard drive's/DVD drive's IDE port seems to firmly hold in place. -Works on (almost(see Cons)) all IDE devices I tested it on, which are... ---Some old 10-12GB or so range 2.5" IDE drives. ---Some old 10GB range 3.5" IDE hard drives. NOTE: some are from original XBox consoles but for these to work they need to be unlocked first. ---80GB(Seagate)/160GB(Western Digital)/200GB(Seagate) 3.5" IDE hard drives. ---Lite-On 1673s DVD burner (IDE connection). mfg date March 2005. ---HP CD-writer+ 9100 (8x4x32) (IDE connection). mfg date May 2000. (see 'NOTE' below) I briefly tested burning a ISO file with ImgBurn on the Lite-On 1673s drive and it worked fine. I primarily got this device for older IDE drives even though I would assume ill have no problems with it's SATA connection (I do have some 2.5" and 3.5" SATA drives I could test) given the IDE drives work. it's basically a great device for making any internal hard drive work externally up to 8TB. NOTE: on my HP CD-Writer+ 9100, being the power port/IDE data port are so close together, it's not possible to use this device 'as is' being the white tab on the molex power plug sticks out which blocks this device from being plugged into the drive to power it as if you plug in the main device you cannot plug in the power to it (or vice versa) as it's physically not possible on the HP CD-writer+ 9100. but what I did to work around that is use one of those 'molex power extenders' I had laying around and hacked off the small white block that protrudes so that I can now plug that part into the HP CD-writer along with this device (as the tab no longer interferes with both the power/IDE being connected at the same time since I hacked it off on the extended molex power connector) and then simply connect this devices molex connector into the extended molex connector (so this device molex power goes into the extended molex power connector and that extended molex connector then plugs into the HP CD burner) and then the device works. but generally speaking I doubt this will be a problem for the vast majority of people who buy this device as all of the hard drives I got have no issues plugging in the power and IDE connection and this device functions perfectly fine.
Easy setup, robust cabling and connectors. Seems to be an excellent product for the price! The drivers didn't come with the product however, so please visit StarTech.com to download them. After this it works great!
