RAID is just a file storage mode that uses extra drives to keep special
information on how to reclaim data should one of the other disks in the
set go bad. To form a RAID set requires at least one more disk than you
are using for storage. For instance, if you want to store twenty-four
terabytes of data you need the number of disks to do that plus one. If
you're using 6TB drives, you'll need five of them--four times six, plus
one more for RAID's private use. If you're using 8TB drives, you'll need
four--three times 8 plus one more for RAID's own private use. 6- and 8TB
drives are the most common in medium- to large-scale storage
installations. Drives from WD and Toshiba are the most reliable,
according to industry papers I've read on this topic.

I don't know what G-RAID is, but you'll definitely be using RAID of some form.
That's your data protection system right there. If a disk goes bad, you don't
lose anything; you just swap out the bad disk for a new one and tell the
network-attached storage device how to deal with the new volume.

that can have 3 or 4 Hard disks that can get my data,
A Network Attached Storage (NAS) device with RAID support should meet your
needs. Some of them apparently support modern file systems such as ZFS and
BTRFS.
This at least should give you the right key words with which to search the Web
for reviews and details. I don't own this kind of hardware, and I wouldn't
claim any expertise on what are currently the leading options.
