testing setup going on so thing that I got going on so here I have seven Seagate Barracuda 3 tbte desktop drives um and I have one Samsung 512 gig 830 series SSD so what I'm going to be doing with these is I have a new raid card here from adaptech this is their 6805 TQ so it includes a super capacitor or whatever it is they call it basically it's it's kind of like a battery backup in that it will allow anything that is cached to be written but it is not an actual battery so it's a slightly different technology one thing to be careful of with these things is you don't want to plug them in or unplug them when they are charged they ship discharg so you can plug them in before you install it but just be aware of that you can mess stuff up so there's the raid card there this supports adap teex Max cash 2.0 so the difference between Max cash and Max cash 2.0 is that Max cash 2.0 supports random ssds it also supports much larger ssds than consumer Technologies like Intel SRT so I want to take this massive raid array I'm going to do the whole thing in raid zero striped so that means there will be no fault tolerance but we will be getting pretty much as much performance perance as you can get from a single single raid card with a reasonable number of drives I mean even this number of drives is kind of unreasonable so this 512 gig cache will be caching 21 TBT of mechanical storage I want to test this we're going to have an upcoming NCI Tech tips on this I want to test this against some sort of more modern configurations to see what we can potentially do with the future of storage compared to a single SSD today a single hard drive today or a h solution like a momentus XT today so here I'm configuring my Max Max cach SSD caching so I've added one SSD to the pool you can obviously add as many ssds as you want to the well no I think it's actually got a limit um whatever it's done now so here you can see my finished configuration I've got my RAID zero set up with my

some performance performance benchmarks I'm going to be using PC Mark and doing several runs because I'm going to be comparing it against some other configurations to see how it B how it uh how it performs at first and then how it performs in subsequent runs with the caching enabled as the controller learns so uh stay tuned for the NCI Tech tips on that and thanks thanks for checking out this configuration process for maxc 2.0 so the eight drives hooked up to the adapt Tech controller are these eight these eight right here are in raid six on the orka controller and I might as well
