Adaptec RAID 2405 SAS / SATA Controller

Windows Startup & Game Loading Results

Windows Bootup Time
 
Quite a simple and self explanatory test. We took each of the three arrays, installed a fresh copy of Windows Vista SP1 on to them and measured the time each took to boot into the Windows desktop and display the Welcome page. To ensure that the tests were fair and that Windows has fully completed installing all devices, the results were recorded after three initial reboots.
 
 
The pattern from the previous page continues, with the Adaptec+Seagate (Array1) being the slowest of the pack by around 3 seconds. However, once controllers are on a level playing field and using the same hard disks, the difference comes down to milliseconds making any performance differences totally unnoticeable.
 
 
Game Level Loading
 
With a fresh copy of Vista installed on each of the arrays, the final test was to see if any of the arrays could offer a significant decrease in the time taken to load a popular PC game. Once again, the test procedure was quite simple: Install Racedriver GRID, load the game, select a track to play and measure the time taken from pressing the "Start" button to the time the track is fully loaded. This procedure was repeated a total of three times on each of the Arrays, with a reboot in between each test to clear system memory.
 
 
Once again the results follow suit with all the other "real world" benchmarks we've performed on this and the previous page, giving us little else to say.

"With an 800MHz processor, 128MB of DDR2 and a PCI-E 8x interface, can Adaptec's latest entry-level SAS/SATA RAID controller offer a boost in performance?"

Nice one Jim!

IT would seem that for a fairly small raid 0 array it is not really worth it...

It would be nice to see a 4 or even 6 disk comparison sometime in the future

I wondering ...

Why you don't mention missing RAID 5 (6) as "BAD".

My opinion, it is very bad.

The second thing that was more then surprising is 2 HDD configuration.

Dedicated Hardware RAID controllers may perform on the same level (or even worse) as software assisted with 1 disk attached.

With 4 disks you can get 300+ MBps read write.

Once, during my work in HP IT department i had an opportunity to play with few RAID setups and found that dedicated hardware controllers begin significantly outperform software assisted controllers like onboard controllers on almost any M/B when used in RAID 5 or 10 setups in system under load.

It worse nothing to compare them like you did.

Try to ran on top of your OS DB + Web serving 500+ connections per minute at least + ran some serious CPU intensive task (like C or C++ compilation) and then you'll see what you paid for with Hardware RAID controller.

But the bottom line, It is good to see that this site reviews not only i7 or HD4870 like others do.

Keep doing it

Quite true, an oversight on my part. Thanks for bringing that up.

Unfortunately two hard disks was all that Adaptec provided us with for the review. Not surprising either considering they are close to 200 each.

Quite true, SAS or 10k SATA are expensive.

If you still have the adapter, try it with regular (7.2k) SATA drives.

(you don't even have to have same model or size drives)

Make 4 drives RAID 0, sit down, run the test

I guarantee you'll have a little orgasm
