Yes ...
The data is not created by me... It has been years and nobody touches the NAS
Unfortunately, I have to use the data now... Could you give me some advice?

Thank you very much!!

You're either looking at a RAID failure (yes it does happen) or bad sectors on one of the disks. Eitherway, if you need the data it would be best to contact a recovery company.

Will the buffalo built-in RAID check helpful? I only have 2 * 2T hard disks but it has already 4 days...

Shall i stop or let it keep on checking?

After 4 days I'd imagine it will not finish.
