Hi everyone,
My first post, and first time using ZEVO. I have an 18tb POOL of 8x3tb drives, that I carry around with me in an 8-Bay USB 3.0 (2 x SATA-II host) enclosure. Usually its hooked up to Nexenta, however now I have ZEVO the pool has become very portable, which is great!
However...
I am observing the following speeds
Writes = 80-130MB/s
Reads = 12-30MB/s
Firstly, I would have expected faster reads than writes and also... I am expecting much larger numbers for both values...
So I don't know if this is good or bad performance with ZEVO, is it optimised for speed yet or only reliability?
Here's some stats....
My drives can do a max of 190MB/s each (approx)
The enclosure has 2x SATA-II controllers... so 3gbit on each...
Host system (my Mac) is a MacBook Pro Retina 15" with 16gb Memory, Core i7 2.8GHz Ivy Bridge and 512gb SSD, vanilla install.
I would have expected to see perhaps 200MB/s read/write at least?... I can achieve around 350-400MB/s read/write on Nexenta... (which I know still isn't the best you can get at all)
So... to sum up a brain dump... is this a limitation of ZEVO, or some weirdness caused by my USB 3.0 enclosure bundled with my Mac etc?
Thanks.
