Very cool! But I sure hope they will make this option available for their existing controllers. I own a 5805 myself. From what I can see, the Q versions are just the same controllers, but with the software license for the SSD caching in it.

swim or sink...Adaptec, will the name remain now that the company has been bought out by PMC-Sierra?

^Legacy hardware, dedicated SSD raid controllers will overtake the market in the coming years.

RAID-6 is doomed, just as R5 is no longer viable. Rebuilding times on TB raids with such low transfer rates makes HDD's impractical at best

Ya, I agree with all the above, interesting links thx.

And also, Adaptec 5805 is a bit overpriced in today's market, instead of announcing MaxIQ-"SSD" coinword cache - really its just +1000 more "cash" :), maybe Adaptec (er-umm PMC-Sierra) should have announced

the 5805-version 2, that is PCI-express 2.0/SAS2/SATA3 ready ?, and it should have supported 6GB/s (sas2/sata3 speeds).

The 5805 is a great card, their software/drivers are very good and adaptec has been around forever.

But, right now, for a good "home", or even Raid system, whats is wrong with this:?

http://www.newegg.com/Product/Product.aspx?Item=N82E16816118112

(LSI SAS 9211-8i, 6Gb/s PCI-Express 2.0) all that for $250 ?!) -heck, this thing can dance, even in a server environment.

As far as Raid levels go,

"Real" RAID is "0+1" aka Raid 10, aka Raid 01, aka "Raid KISS"... you get more raw performance, with redundancy, from this Raid than "ANY other Raid period !

It is also the simplest and "fastest" RAID to create/rebuild/... I'm sure better storage guru's than me know this.

All these "other" Raid level's(5,6,50,60,...) were historically designed to squeeze every bit of space they could outta drives, but at $100/per 2-TB Drive does anyone really care about space anymore ??? :)

-even SAS, and SSD drives are coming down in price like crazy.

the Adaptec's MaxIQ-cache-SSD is NOT worth dumping over +1000 $ unless its super-mission-critical.

Either way, the only viable Raid that was the first, and it will be the last Raid to go, is the simple "mirrored-stripes" 0+1
