Areca 1680ix SAS Madness 1gb/s +

[Nizzen]

Areca 1680ix-12 and 10 Seagate 15k.5 74gb SAS in Raid-0

This is now my new OS Vista 64 drive

[Speederlander]

You're going to use a 10 drive RAID-0 for day to day?

Could you also show a single drive pass-through and 5-drive RAID 0 for scale? Also, if it's not too much trouble (since I know how easy it is to set up RAID arrays with that 1680), could you do an 8-drive RAID 0 using these parameters to test:

and post it? I'm curious about the difference between SAS and SATA on this controller.

What is the cache size?

That's the highest STR I've seen on the 1680. What firmware are you using?

[Nizzen]

I use 512 MB on the kontroller now. Firmware is 1.45F, that was orginal with the card. 2 gb ecc is ordered, so it is coming soon i hope

Here is 6 Seagate SAS in Raid-0.

[Speederlander]

1.45F ?

Does it have a numbered version like 145-80915? When I get home I'll tell you the format it appears in on the acrhttp interface.

Try that crystaldisk with 1000MB. You're just benching your cache with that 50MB.

Those numbers (post #1) aren't strange for RAID0. It's RAID5/6 that won't be able to handle this much... (I've compared this, R0 can give >1000MB/s with 8 of the same drives as in post #1, but RAID5/6 with any number of drives won't pass ~700MB/s).
I ran this on the regular 1680, not ix.

Did you got over 900 MB/s read speed? Did you Use SAS or SATA?

[alfaunits]

Yep - 8 of the same drives as you did - 15K.5

Do you have pictures of it? Or did you write a "test" ?

Nice for compare

[alfaunits]

An 8-drive RAID0 was something I just tested, I had no intention of using it full-time.
Try it yourself, you have the same hardware, you'll see it's possible with 8 drives, 10 aren't required.

One thing I see here is that you're test sizes fit into your cache. hdtach would appear to be streaming reads to the subsystem so depending on your read-ahead value that will inflate that some. hdtune I don't think has much control over the number of files (you have a file size of 256mb which is large but still within cache) the question is how many of those files is it creating (tens, hundreds, thousands?) I haven't used it in a while but I don't believe that it creates the numbers of files needed. crystaldiskmark you have set for 5 iterations of 50MB in size which is only 250MB. Set it to 9 iterations of 100MB (I think that was the largest but it's also been a while). Also you want to disable your OS cache so it's not influencing your results.

This has got me in the mood to run some iozones against the raid-10/8 savvios I have here at least a single pass worth at each stripe size since I don't need that computer much this week or so.

Holy . Great numbers, but I think you'd definitely benefit from throwing a 2GB DIMM in that controller.

[Sandon]

I would like to see raid5/raid6 benchmarks.

[alfaunits]

Literally half of that in post #1.

[Nizzen]

Raid-5

[Speederlander]

Use the settings here:

And post up iometer results.

Thanks.

[alfaunits]

OUCH! Those numbers will hurt e-p***ses

[dinos22]

OMG look at that Raid5 performance eek

[ticalOne]

Crazy stuff, what else can one say. Impressive indeed

With all the problems I see with SSD, especially the almighty intel x-25, scsi is looking good again. I'm drooling.

[alfaunits]

Don't get too drooly, the named controller maker has caused more problems with lost volumes and data than one can count... speedy, very good options - but they forgot the basic option (keep the data safe from the controller at least).

What's the best RAID 6 Adaptec available?

[alfaunits]

I don't think their series 5 line (the ones with IOP348) differe much from each other except with regards to available ports.
I'm waiting for pricing confirmation on 52445 (24 internal, 4 external), but IMO the 5805 is best (low profile, 8 internal ports, enough for most).

5805 is perfect for all purpose workstation.........

Isn't the Adaptec 5 series very hot? I think my Adaptec 31205 is hot, så i use a low rpm fan on it

it can not run without active cooling. I HAD to put a 120mm fan on it or it overheated, beeped, and turned off. This was in an open case and in 15C environment.
