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 256MB cache memory allows the drive to process frequently used files extra fast.
The hard drive doesn't make a lot of noise while it's running.
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 6TB 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 quickly transfer files 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. This is useful if you use the NAS as a work server, for example. With a 28dB maximum noise level, the hard drive also doesn't make a lot of noise, even if you demand a lot of it. You get a 3-year warranty on this drive 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.
