Doing a rebuild using a 25yr old motherboard with PCI/ISA bus. This PCI card is recognized by Win98 but drivers are not included with the product, are not all present on the Win98CD (original or Second Update) and links in the paperwork sent with the card no longer work (not really surprised after 25 years). Fortunately drivers are available at www.philscomputerlab.com/windows-98-usb-storage-driver.html in the file nusb36e.exe. Run the EXE under Win98 before installing the card. All Win98 drivers will load automatically upon powerup after card installation. Now I can use USB keys to move files rather than floppy disk or CD. Having fun playing Doom 2.

Looks to be well made with the SATA ports attached solidly to the card (I purchased a few from other manf. in the past where the SATA ports broke or became loose and I had to super-glue them back on). Easy install: -- driver support as far back as kernel 4.18.16-300.fc29.x86_64, so happy about that! -- came with power and SATA cables - so it's a complete package for the price.

I bought this for my P.C. because I made my gamer for the living room on the 65" TV. It works perfectly, no more jumping up and running across the room every time I want to utilize one of my P.C. functions about 5 times a day! Remote does exactly same as 2 counter part buttons. I can start it up, I can reset it if froze up, and if you hold down power button it will do a forced shut down, But that is never recommended, use your mouse and shut down correctly the save way, for continuous good start ups! & remote control battery I get free from V.A. for my Accu-Check blood sugar meter.

This replaced another StarTech powered PCI USB hub that uses a driver that is incompatible with Star Citizen, of all things. That specific driver was causing SC to crash reliably. Research told me that this newer model uses a more up-to-date driver and that the issue should disappear once installed. Absolutely correct. This device functions as expected and uses a driver that does not cause crashes in Star Citizen. Happy Days!

Always need space :) I have built a system that rocks .. so far 7 hard drives. 1 SSD. Will be adding bigger hard drives soon like 26bTB either 5 to 10 of them will be fine.
