Hi all,

I am looking at building myself a fairly decent file store/NAS, and im trying to find some place in NZ that sells SATA port multiplier back planes. Has anyone seen them around for a reasonable price? Cheers

I didn't think you could run more than one Drive off a single SATA port.

Neither did I.

I was reading this article, which mentions them:

Petabytes on a budget

and then found some more info on them in this wikipedia article:

wikipedia port multiplier

A quick Google search shows quite a few places selling gear in NZ.

This here is probably the best price http://www.pcssl.co.nz/productdetails.aspx?cmd=526-83

or this if you want an internal solution http://www.pcssl.co.nz/productdetails.aspx?cmd=740-93%22

Only downside with this is you need a chipset with PM support to use it.

Interesting, I wonder how a single port multiplier compares performance-wise against a standard PCI or PCI-E sata raid card.

Also those BackBlaze storage pods look awesome.

I'm not really sure, I really only found out about/started looking into them about 2 weeks ago. I would imagine there must be some speed loss though ie 3gbps shared rather then per drive

Yeh good point, the only thing I have read about performance is that all drives on the port multiplier obviously share the one sata channel, so performance for all drives on it would be no greater than 150MB/s/300MB/s. (not sure if they work over SATAII)

I tried one for a while - it came in a 4 bay external sata enclosure.

I guess if the 4 drives were in a raid it would work ok, but I was using them as 4 seperate drives.

If I was copying for example a 20 gig rip from the system drive to one of the 1tb drives, playback of music off another would skip badly.

In the end pulled the multiplier out, got 4 sata to esata cables and another PCI-e dual port sata card - now it works fine.
