Compare Crucial C300 64GB versus Acard 9010 under Areca 1880 4GB Cache

[SteveRo]

^^ I don't remember the name of the areca engineer but he was very cooperative/responsive.
Unfortunately - no luck on a fix.
About disabling the cache - sure - performance takes a big hit.
But you know - the 4GB cache is why I bought this card in the 1st place - why would I want to run w/o it?
My areca POC also reported that all 1880's with expandable cache and one or more of the 1680 series all have built in expanders and as such the acards will not run with these controllers at sata300.
Now that said - there are 1880s that do not have the expander and in those - the acard's will run at sata300 - areca tested this.
I didn't want to go that way because the cache was something like 512 or less - not what I was looking for.
You have very good options with the acards though - i believe they run well across most controllers.
Particulary - they seem to like the SB P67 PCH.
This is hopefull in that they may also perform well later this year when SB-E arrives.
All acards that I have are personal property and I doubt I'll be interested in selling any until I find something faster.

''areca engineer but he was very cooperative/responsive'' YEEAAHH

areca worck actualy for find a solution ? or never find a solution ?


disable cach its interessant for compare and see the real storage bandwidth, in bench and reél using this 4G bufer its very fun and powerfull

Its incredible sata 300 bug in this 1880ix, I can understande sata I 150 not worck but sata 300 ....

If you can tel areca for not IRAM compatibility with 1880ix, I think its just due to this device is not add in compatibility device suport. sata I certenely worck with this HIHIHIIHI


The good perf with SB its due to the PCIE direct in CPU, this is very good.

I have already test the lost bandwidth due to the nf200 (in my SR 2). The latency its very bad and lost lots IOPS .
nf200 very SUXXX prefer two 5520 for lots PCIE, hihi ...



""All acards"" 16 acard at you ????????? you have just 28G total volume ?

Its just for great PCm score ?



I have a noob question:


the frontal port can be using ?
its desactivated or not ?
I m not find the good cable conecteur for this.

[SteveRo]

Sorry, I do not use that port at all, not even sure what connects to it.
I do use the external ethernet port, that comes in real handy.
Nice to be able to access the card w/o needing to go thru the host machine.

[mosie]

this port its a mini sas, but strange mini sas.

In soft HTTareca we can see 4 ID more.

I have 1880ix 16 and I ahve 20 ID port



possible using this ?

[SteveRo]

Seems like I remember that if you use this you lose 4 from the internal? Get a cable and check it out for us!

[Anvil]

I believe that Nizzen has tried it and it worked, need to get him to confirm though.

[Nizzen]

I am using the external port for external hddbay It is just an external minisas port. Working just like the other internal minisas ports

Perfect for testing ssd and hdd
The SFF-8088 to SATA x 4 is very expensive

With this cable the Areca 1880-24 have 28 ports! All working at the same time.

[mosie]

''if you use this you lose 4 from the internal"

I have imagine this.


THX Nizzen

Whene U use this external minisas its disable one internal minisas ? or UP to 4 port sup all in full working ?

EDIT: ""With this cable the Areca 1880-24 have 28 ports! All working at the same time. "" WOW good

need an auther cable.

[Computurd]

looks almost like an infiniband connector. so nizzen, let me clarify

if i use one of these my 1880-12 will now be 1880-16? it will have sixteen usable ports?

[mosie]

Apparently, YES

I have bay one SFF 8088 for test this.

Yes thats right

[mosie]

Just need a solution of areca for sata II ACARD.

erf !

[SteveRo]

^^^ I hope you find the solution!
If you do give us a shout!

[mosie]

I a m not the solution.

Its a clearly bug due to the areca firmware, areca need find the solution.

Do you have a news for areca worck progress ?

[mosie]

no news for the compatibility problem ?

[Anvil]

I ordered the EXT-MS-1M4S (for the external connector) and it worked just fine
