Even (or especially?) For the private high-end users ...

I have worried me the controller about a year ago from another dealer, as this
Amazon was out of stock, the Intel onboard controller simply unprofessional
are and I went on the cookie. The Intel Rapid Storage Software with the nonsense
for their genuine Raid just nonsense.

So who is purist and honest data transfer rates (and not by caching hochgekünstelten rates) ((because there are
Have users, who imagine that the 840 EVO with Rapid mode enabled makes real 1GB / sec!))
wants, comes at a decent RAID controller does not pass. Sure you can for the price alone for
4 + 4 SSDs HDDs + 9271-8i a complete PC put together - but a hightech, which also makes a lot of data transfer / unpack,
is this configuration to know more than appreciate.

The controller performs according to use an HBA (Host Bus Adapter), which was disastrous, very
good work. He is always very fast, works reliably and operates a Raid 5 (4x 2TB Seagate .14er series - 5TB net)
and just a Raid 0 with 4x Samsung 840 Evo 250 GB in RAID 0. The configuration is exemplary and easy Bios
the controller to do. A graphical user interface with mouse control helps immensely here.

The transfer rates I have immortalized times for one or the other interested parties as a screenshot here at Amazon.
As is activated when the SSDs "Read / Write through", the flagpole is at 1.8GB / sec. not been reached.

With the cache enabled push the 4 SSDs in Raid0 2,2GB / sec. via the controller. Since I no battery backup but
Only use a UPS as the primary security, the active caching is disabled in the SSDs. 1.8GB / sec. should
well enough and do the 64kTHRD access just to good.

Configuration is as follows:

- Core i7 2600K @ 4.5 GHZ (water-cooled)
- Asus P8Z77V-Premium
- 16GB Ram
- LSI 9271-8i with 4x 840 evo in RAID0 + 4x Seagate STDM2000.14 Raid 5 (PCIEx 3.0)

The copying of video data and also many small individual files from RAID 0 to RAID 5 is with
ca 550MB / sec done. It does, in practice, almost no matter whether small or large Dateiuen ...
For conventional Seagate hard drives a peak. 10GB are thus copied in a few seconds.

The MegaRAID software and driver installation went without any problems - the driver is
preloaded and the Win7 setup from USB stick afterwards not even need
are installed. The software has a very good and self-explanatory.

(But little idea of ​​the matter is compulsory)

Conclusion:

Here you get something for your money - for the ambitious Highender which in themselves play
would be more than 3 seconds load time, move data from A to B in seconds,
in record time large ZIP want unpack archives, which is absolutely right here.

For me it will be in the near future no alternative - except a second
Controller and 8x SSDs in RAID 0 + 8x HDD in RAID 5)
