QNAP TS 264 NAS

[Enquiries]

Hi

Thanks for all your video, that helps me a lot to understand and select which nas i need but i have a question.

I'm looking for the QNAP TS 264 but i think that 2 bays will be not enough for a long time keeping.
I checked the QNAP TS 464 but it less powerfull than his little brother.
So if I buy the TS 264 and in the future, add an extension like the TR 002 is this setup working well and more powerful than the TS 464 itself ?
Is there a lost or performance for RAID 1 with an extension ?

Thanks in advance for your answer and sorry if i made mistakes in my message i'm not english.
