You need to read the question properly.
He is asking about RAID0 STRIPE, not RAID1 MIRROR.
My answer: YES you will have a significant speed improvement.
ref: http://staff.science.uva.nl/~delaat/rp/2009-2010/p30/presentation.pdf
Speed:
My workstations do run Linux Mint using software raid (mdadm)
and I do run 4 drives in a stripe having XFS as filesystem.
Once you sit on such workstation, You do not want to turn back
to the old days with ONE platter drive.
Backup your workstation daily with incremental backup, weekly
a full backup just in case one SSD crashes.
Your speed is great but if ONE ssd does crash You loose a lot of data.
So You are warned.
Backup and use cloud to store additionally files.
Storage:
My NAS is purely running FreeBSD ZFS ZRAID2 for storage
with 2+4 drives of 3TB, so I have 12TB and 2 drives of 3TB do provide
redundancy, so I can loose 2 drives at a time without loosing data.
My NAS does run on regular drives.
ZFS is currently the best filesystem for disks, for sure for storage.
You can look for FreeBSD or a dedicated NAS software solution such as FreeNAS,
ZFSguru, NexentaStor ... I did choose ZFSguru because I do like to teweak
the FreeBSD system. I use iSCSI and SMB/NFS shares on it.
Servers:
My favorite is to use platters for ZFS and use SSD for ZIL in ZFS.
But it is dark art.
NOTE 1:
Try to avoid hardware raids, in case of failure You need to have the same
hardware again. Do not use the cheap raid controllers on the customer
motherboards. Try to use software raid supported by the OS, just for sake of
recovery, as the OS has more ways to deal with raid as most crappy raid software
in those hardware controllers.
NOTE 2:
When using ZFS avoid at all costs hardware raid controllers. Look for
motherboards with enough SATA ports to connect Your drives. There are
dedicated controllers to without raid functionality.
Setup the raid using ZFS
NOTE 3:
SSDs no longer scale after 4 disks
HDDs continue to scale after 5 disks
NOTE 4:
There are different types of SSD
You have SSD SLC and MLC. The first are the most expensive but
the fastest and the best for heavy read/write operations.
I can now confirm that the problem I experienced booting my cloned Samsung 970 Evo plus NVMe SSD into Windows is now solved!
I was advised by Macrium to try booting into Windows in safe mode. They thought that loading Windows in safe mode with a minimum drivers, etc may enable Windows to boot far enough to find the new drive and load the NVMe drivers. I tried this and it worked! Once I was in Windows in safe mode I went to Device Manager and sure enough the Windows NVMe driver had been loaded and the drive was present.
I then logged out, shut down and restarted the laptop in standard mode and everything loaded as it should. I have now updated to the Samsung NVMe SSD driver and run some diagnostics and benchmarks. All is running as it should and much faster!
I would like to say a big thank you to all the forum users that took the time and effort to provide a response with help and suggestions to assist me with this problem.
Sometimes the simplest solutions are the ones that you don't think of!

Have a look in the performance Monitor (perfmon) for the 'Avg. Disk Queue Length' on that disk.
If it's anything above 0.0 (1.0 etc), then the system is waiting for the disk, and your disk is the bottleneck. If the wait stays below 0.1. (say 0.001) then the disk isn't being slow.
