Pros and cons

According to our internal hard drive HDD expert

This drive was designed for 24/7 use in a Synology NAS and automatically receives firmware updates.
The 512MB cache memory allows the drive to process and open frequently used files extra fast.
This drive is filled with helium, so it's more energy-efficient and lighter.
Due to the 3.5-inch size, this drive doesn't fit in a laptop.

Description

Store your files and documents safely on the Synology Plus Series HDD 12TB internal hard drive. This 3.5-inch internal hard drive is suitable for a Synology NAS and works with all Synology services. For example, the drive updates automatically if there's new firmware and runs constantly without problems. You can transfer files in a few seconds thanks to the 7200RPM, so you can keep the loading time to a minimum. The 512MB cache memory also allows you to open frequently used files faster. That way, you can also use this NAS for a medium-sized office and with multiple colleagues at the same time. In addition, this hard drive doesn't use a lot of energy because it's filled with helium. This makes the drive lighter and more energy-efficient. You get a 3-year warranty from Synology.

Good. But expected better

Synology in Synology
Trustworthy(?)
A bit slow

I expected a faster drive, considering this was a dedicated Synology hard drive, or one specifically designed for my Synology NAS. It also makes more noise than my old drive, which isn't a dedicated Synology drive. Considering the higher price, I also expected better.
