Windows 10: RAID 0 Risky but for speed absolutely well worth it 400 GB in 71 min

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

Help, features I'm failing with, on an N95 8GB

You may need a new calculator also

40mins to transfer 1.3G which is less than 400KB/s.

According to my calculator 1.3 GB of data in 40 mins. yields a datarate of ~ 542 KB/s not 400...

Seems low, I get faster speeds.

 

Raid0 restore help

RAID is a collection of techniques to speed up access and to protect it. If you are interested, this wiki goes into detail:

RAID - Wikipedia

Raid 0 is probably the worst possible choice for that drive mix. Raid 0 splits the data across the drives in an effort to speed up retriveval. But it is based on the assumption of similar sized drives and identical technology. But your drives are significantly
different in data retrieval speeds and size, so mixing them in a Raid 0 pattern is totally illogical. The worst part of this mix is that if you lose a single drive you lose ALL of the data, with no chance of recovery.

BEFORE you do anything, make a full backup of all of your files. Trying to split the drives you stand a very high chance of losing your data and being forced to start over with a clean install of Windows.

 

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.
