<p>its a good idea, I use Fusion IO SLC drives but I still see a limit of about 750 MB/sec which is too little, also I need to run multiple streams to achieve this, if I only use a single data stream I only get around 350 MB/sec. I makes no difference if I
use 1 or 4 SLC drives, speed remains pretty much the same +/- 5%.<br>
</p>
<p><br>
</p>
<p>After testing some mSata drives in one of Intels NUCs it became interesting to investigate if it would be possible to get a motherboard with say 10 or 20 mSata slots, I even asked SuperMicros engineers and they said no coz its not an enterprise product. <br>
</p>
<p><br>
</p>
<p>However there are some PCIe cards available where you can attach mSata drives and even raid them and while I havent tried this yet, I think it could deliver some nice cheap SLOG perforformance <br>
</p>
<p><br>
</p>
<p>check <a href="http://www.addonics.com/products/ad4mspx2.php">http://www.addonics.com/products/ad4mspx2.php</a> <br>
</p>
<p><br>
</p>
<p>Maybe there are better products out there, this was just what I came across initially. <br>
</p>
<p><br>
</p>
<p>Maybe even completely skip a dedicated log device and set the pool to sync=always and base it on for example 8 of the above PCIe cards each with 4 1TB drives and you could have 32TB raw SSD ultrafast storage in a 3unit and with compression and possibly dedup
you could easily store a lot of data on even when mirroring.<br>
</p>
<p><br>
</p>
<p>This is probably my next project anyway so interested to see what you find out in terms of upping the speed and lowering the latency.<br>

<div>Hi guys,<br>
<br>
</div>
does anyone played with some of these PCIe devices on the market as a cheaper ZIL dedicated device instead of
<a href="http://www.hgst.com/solid-state-storage/enterprise-ssd/sas-ssd/zeusram-sas-ssd">
this one</a> for example that would work with OmniOS out of the box?<br>
<br>
</div>
<div>Here's one of the products I have found in the Internet googling around but it's way too big for the purpose:<br>

I am trying to find a good price/performance balance when full SSD storage based pool is in use.<br>
<br>
</div>
Thanks in advance.<br>
