Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.

Difference between RAID 1+0 and RAID 10E?

Kinda hard for me to explain this 1E and 10E, but this should help:

simply put 10 is for an even number of disks, and 10e is an implementation of 10 for an odd number of disks.
Oh... please show me where it's mentioned.wikipedia is ur friend

Thanks for the clarification. I was reading about 1E0 that mentioned that, and general "Enhanced" RAID configs; but nothing explicitly about "10E," and was wondering if there was something off about it.
Okay... so "distributed strip-set, with distributed mirroring" safe to say?
What would be the total drive capacity, and amount of allowed failed drives? N-1 capacity, and 1 drive failure?
Thanks!

RAID 10E is a proprietary standard from IBM.
Our IBM servers at work have it and we use it.
It's essentially RAID 10 with some additions. It's controller dependent and not a standard (AFAIK)
RAID 1E0 seems to be mentioned as this IBM proprietary standard.
However, I'm asking because 10E is supported by an LSI adapter on an HP XW4600 workstation.
Interesting. I think I'll call LSI for fun and excitement and post the answer here.
I have found a fairly extensive answer at http://www.infostor.com/article_display/lsi-expands-sas-sata-lines/271226/s-articles/s-infostor/s-sas-resources/s-sasrc/s-1.html
to sum up the article for the quick glance
According to McCarthy, Level 1E is enhanced mirroring, which offers the same functionality as RAID 10 on an odd number of drives, starting with three. RAID 10E is the same as RAID 1E, but on an even number of drives.
Hope this helps!
