ssd?

Yes, you could just do a swap of your HDD and SSD, as they're both SATA and the current cables are compatible. The cable you linked would work for your second SSD, but you still need another power cable. Most manufacturers of non-modular power supplies have multiple power outputs on the same SATA cable. See if there is another one on your cable connecting to your current HDD before you go and buy one. If you have a fully modular or semi modular power supply, the sata cables should be removable and thus if you're short on one, you should be able to buy a replacement from the manufacturer's website or Amazon. A fresh install of Windows should work perfectly fine. I'm currently running the SSD you linked and it's worked quite well for the past few months, however you said you wanted to install a second SSD. If you have a higher budget, and an NVMe data slot on your motherboard, I'd recommend this M.2 SSD from Samsung. www.amazon.com/Samsung-970-EVO-Plus-MZ-V7S250B/dp/B07MG119KG The M.2s are much more capable through newer hardware, and your OS would boot and run noticably faster than on an HDD, or even a SATA SSD in my personal experience.
