Question Replacement RAID drive: Need exactly the same?

[flying_suser]

I've a failed RAID drive , for which I wish to replace the faulty 4TB drive. AFAIK , the replacement drive has to exactly the same in size
as the dead one.

Off topic: I've a few questions on that particular RAID, which I would like to ask in a separate thread.

The failed drive has the following specifications:

Seagate ST4000DM000 P/N: 1F2168-300 F/W: CC52 WU Z30 4TB



The exact same drive is available on Amazon. However I'm thinking if I can replace it with a newer generation
4TB hard drive like the following:




Awaiting your responses

The replacement drive should always the same size or larger than the old one.

They are all the same drives, model ST4000DM000, just made in different countries, China & Thailand.

RAID what? and using hardware RAID, software RAID, ???

Generally speaking, you do have to match sizes at least, although you can often do that with partitioning.
