RAID 0 Risky but for speed absolutely well worth it

Hi folks

If you take back ups regularly (and you always should) then using RAID 0 IMO is really well worth it -- speeds up Disks considerably and you can add as many as you like to array (min 2).

Of course it's risky because if you lose a disk in the array you lose the lot ! however I always take backup

Here's backing up to an external USB 3 HDD around 400 GB of music saved from BBC R3.

Shouldn't take more than around 40 - 60 Mins !!!! -- speed is varies between 60 - 90 MB/s ( 240 - 360 Mb/s) from HDD (RAID 0 -- 2 X 5 TB HDD's) to a self powered USB 3 passport external HDD.

the limiting factor is the speed of the small pocket sized external WD passport drive -- the poor thing is running at about max on this type of connection --especially as a VM on W10 Host. Running internally you can get speeds of up to around 500 - 600 Mb/s even on old SATA 3 gb/s Mobo connection. Nothing like speeding up I/O - especially on older type systems.

Running actually from a NAS server running as a VM on W10 X64 Pro with latest updates -- not the SCU though.

The CPU is only a modest Intel 2.4 GHZ 2 core celeron -- about equiv to an i3 so no massive CPU needed for decent XFER's.



No SSD's involved in this -- with SSD's in RAID 0 I'd imagine the system would fly off the bench !!!! The only concession on the HDD's is that all of them are using Linux XFS native file systems so no NTFS conversions needed via the VM software (Vmware workstation rel 14).

The HDD's seem reliable enough but always worth having backup !!!! especially with RAID 0.

Nearly 60 % done now and only around 25 mins left !!!



Finished 400GB Xfer in 71 Mins !!!!

total size is 430147038575

On my work desktop I run two Samsung 960 250GB SSDs in RAID 0 and really love the performance. It is totally overkill, but could provide some true uses for those moving a lot of data constantly. For testing, I was reaching 1GB per second writes and reads.
