Areca 1880

[SteveRo]

Seems like it has higher access times...
But I don't find these speeds to be low in any way, with 4 ACards at SATA150, you would max out at ~450-480 MB/s for all 4.
The ridicolously high reads/writes (>1GB/s) are just cached reads/writes, so they're not comparable.

As for the 12 ACard not doing >1GB/s, that's another thing.. try setting volume read ahead to aggressive? It could be the 1880 just doesn't like SATA well.

When I can get the 4Gb mushkin to work - I get nice numbers, the seqential reads are much improved.

For me the 1880 really seems to need the large cache to shine.

And yes, read ahead is set to aggressive.

The 1880 seems to work fine with many SSDs based on several posts in this thread.
The drives I have available to test with are not the standard SSDs, acards and mtron mobi's.
Neither supports ncq, acards based on ddr2 dimms and mobi's are 1st gen SSDs based on SLC flash.
I plan to order the tekram 4GB memory this evening and give that a try.
