I am trying to check that if I buy a new internal HDD it will work in the NAS I am buying. Currently I'm confused about naming schemes and once that is resolved whether there is compatibility. I will gladly author this question to be more general if there is not already an article helping with the confusion of SATA naming and standards. I see similar, but not identical questions and will accept this as a duplicate if thought as such.
The specifications on the eCommerce site for the NAS says, "Controller Interface Type Serial ATA-150", the product home page for the manufacturer says, "Compatible with SATA and SATA II HDD".
The specifications on the eCommerce site for the hard drives say, "Interface Type Serial ATA-300", the product home page for the manufacturer says, "Interface SATA 3.0 Gbps"
Wikipedia says many things about different naming conventions, the closest being, "SATA II 3.0 Gbit/s, which was colloquially referred to as "SATA 3G" [bps] or "SATA 300" [MB/s] since 1.5 Gbit/s SATA I and 1.5 Gbit/s SATA II were referred to as both "SATA 1.5G" [b/s] or "SATA 150" [MB/s]). Therefore, they will operate with negligible differences between them."
Are SATA II and SATA 3.0 Gbps the same? I feel I'm tantalisingly close to getting a definitive answer here before I purchase, but really want to clear up these naming schemes.
