There is no "best raid level". Depending on your requirements you have to make decission between "capacity", "performance" and "safety". You will only get one of the three. If you want to get two you always have to spend some more money because extra disks are needed to archive your goal.
There are some variables like large and slow harddrives (think about a 10TB disk) and rebuild times in a case of a drive failure within a raid. Depending on how long it takes it increase the risk of a double drive failure. A double drive failure can be survived with a RAID6 or if youre a lucky one with a RAID10 (if Mr. Murphy is nice to you).
With only 2 disks go for a RAID1. The 2x300 gives you a capacity of around 285GB and depending of the OS and choosen filesystem you have ~275 at the end.
I suggest to replace the PERC6 battery before getting the server back into "production" and please backup your data on a regular basis.
The initial configuration of the PERC6 within these old servers is quite simple and i like the DOS like menu very well because i was familiar with it(we are a dell shop). But you should also install OMSA as an application later to get some insights from the OS level too. OMSA comes also with command line tools like omconfig and omreport. I cant remember if special megacli tools also works with old PERC6.
because performance isnt the top priority go for RAID6 for max. safety.
I cant remember if a online raid expansion was possible with the >10 year old PERC6 or H700 but even than it can only be work if there is only one Virtual Disk on the RaidGroup. In the Perc manual you will find a table which RAID can be modified or expanded.
Thanks for information, i`m beginner and i dont have knowledge to setup dedicated server.
Im very confused for now, which option is the best way to choice the type of RAID. i will need storage ahead in time if the hdd is full. Could you suggest me , These 2x300gb RAID 0 should be or RAID1? Sorry for bad english.
I have a Dell Poweredge R610, It has the original Bios and Lifecycle on it. I am trying to update the Bios and iDrag, but under the boot sequence in lifecycle it does not give me an option for USB or DVD. How do I update this old server?

IIRC the usb stick only becomes visible when plugged into ..... just press the FXX (f12?) key to enter boot manager during server startup. If the server uses UEFI try to reconfigure it back to BIOS mode because this makes it easer to handle boot devices.
For sure a 11Gen supports boot from USB because i once have ESXi installed and and runnin on USB in those old servers.
If its a iDRAC enterprise you can upgrade iDRAC/LCC over the web gui.
Otherwise install a Windows or Linux and use the Dell DUP one after another.

The table i mentioned in the first post is shown here https://www.dell.com/support/kbdoc/de-de/000175364/reconfiguration-of-virtual-disks-on-the-poweredge-raid-controller-6-perc6?lang=en
But just grab the manual of your PERC6.

With just 2 disk you have the choice between
if you buy one more disk
and if you buy 2 more disks
because performance isnt the top priority go for RAID6 for max. safety.
I cant remember if a online raid expansion was possible with the >10 year old PERC6 or H700 but even than it can only be work if there is only one Virtual Disk on the RaidGroup. In the Perc manual you will find a table which RAID can be modified or expanded.

Dell doesnt offer the platform ISO`s anymore.
