there arent any out there other than kingston, which are discontinued, thus expensive as hell.

Atto is epic fail with a controller with cache.. The numbers are most cache numbers.
Use Iometer, everest, or even hdtune. Crystal diskmark with testfile over cachesize and ASS ssd bench.
5R0 Vertex 2, 60GB, stripe size 32KB
7.9 all the way, looking good :)

WOW awesome results!
I know Nissen I only have 512k but I suppose it still kicks in even so on writes even when testing 1gb atto. I will take your advice though still not sure what best stripe size to use general usage with the areca seems they like smaller stripe size. Any suggestions for boot and apps general use 128k or smaller with this areca?Quote:

that version of the card does not allow memory expansion, only the arc1880ix-12 and up allow expansion!
that unit comes with 521 mb of memory, no upgrading!
(should still be a good card, but for that much cache i personally wouldve gotten a 9260-8i. better low cache performer!!)
i wish i would have known about this earlier today. hopefully the new setup is better than my motherboard controller with my intel drives.Quote:

Is the ARC-1880 including Multilanes?
Should I leave 64k as raid 0 stripe size? I setup the raid as quick volume raid setup. Should I do it in any other way?
Hlo
experiment and see - with areca controllers with SSDs usually smaller strip is faster.

1880 beta bios :D
I will try tomorrow :up:
Good night from Norway :) (00:25)
ty nizzen for the notice!
this is what i was waiting for! i knew they had to be running an older sas set because they seemed to be running the same FW as other cards on it...Quote:

Mr Anvil should chime in, with SSDs instead of acards I thought 4k stripe was still the best.
Wow CT, huge score there guy!Quote:

Very nice numbers Mr Nizzen, what drives and how many?
Do you have your 4GB cache yet?
I'll find out this weekend.Quote:

They epic failed and sendt 2gb memory. 4 gb memory with UPS express :shakes:Quote:
