in order to check if you have received SSD or HDD try the below method

On the latest kernels the SSD disks are automatically detected.

To fine Hard drive path


fdisk -l

Replace sda with your hard drive path.

$ cat /sys/block/sda/queue/rotational

The result of the command will be a number

1 means you have a HDD
0 means you have a SSD

You can also test the below commands:

#lsblk -d -o name,rota
--> output will be as "1 if SSD, 0 if HDD"

# lsblk -t

For Hardware RAID, try something as below. May be based on the model you can find information:
# tw_cli show
# tw_cli /c2 show
