Reddit mentions of Samsung SE-506CB/RSWD 6X USB 2.0 Slim Blu-ray Writer External Drive (White)

The good news is that the discs that came with the hardware are obsolete and the updated software is available for download on their sites.

The bad news is some software, depending on the vendor, must be installed from the included disc because they do not offer a replacement on their site (to minimize how many people who don't own compatible hardware try using it). Creative and Canon with their DSLR's are two examples where proprietary software is exclusive to their included media and the website merely offers patches.

Also, your OS is downloadable and can be very easily installed to a USB drive of 8GB minimum capacity (it will be formatted to FAT32)

• Windows 10 Media Creation Tool
  
  
• Windows 8.1/8 Media Creation Tool
  
  With the spare storage on the USB drive, I would create a folder and place all your driver downloads there UNcompressed and sorted so your OS can find them when you point to it.
  
  If you are installing Windows in new hardware, remember to boot off the USB drive in UEFI mode (use opportunity to ditch MBR). After pressing the appropriate key on startup to dictate the boot device, look for UEFI next to the USB drive. Desktop motherboards allow you to boot with the typical BIOS/MBR method or the UEFI/GPT method without having to make any modifications, whereas laptops may require you disable "Secure Boot" before permitting booting

  Finally, remember to save this drive in a safe place for future use. Like in your motherboard box.
