TweakTown Rating: 93%Manufacturer: Areca



We would like to thank the following companies for supplying and supporting us with our test system hardware and equipment: AVADirect, GIGABYTE, LSI, Corsair and Noctua.


You can read more about TweakTown's Storage Product Testing Workstation and the procedures followed to test products in this article.


For this test we got to break out our X79 test rig with PCIe 3.0! This system isn't used too often since the Intel SATA III ports are not as fast as those found on Z77 systems. This system does have a very good PCIe 3.0 subsystem that allows us to stretch the legs of the Areca ARC-1882i.


Feeding the ARC-1882i were eight Crucial m4 256GB drives with the latest 000F firmware.



ATTO Baseline Performance


Version and / or Patch Used: 2.34


ATTO is used by many disk manufacturers to determine the read and write speeds that will be presented to customers.




Without explanation you might think we did something wrong or broke the Areca ARC-1882i V3. Well we did break something, but it wasn't the hardware. I will let Paul, our enterprise storage guru explain it, his version is so much better than mine. Here's what he said to me:


"You have quite literally broken ATTO. You went over the amount of speed that ATTO will display. The ATTO benchmark uses 32 bit unsigned integers to store the results, so it cannot display numbers bigger than 4294967295 bytes/sec.


In other words, it isn't going to show you anything over 4.29GB/s. At that point it begins to "wrap around". You simply add the amount that it shows for 64KB to the 4.9GB/s. So if it is over by 1.2GB/s that would mean you are at 5.49GB/s.


Congrats, you are the only other guy on the planet that I know personally who has run into this!"


Well then, I would say it is time for ATTO to fix their broken benchmark software because the Areca ARC-1882i just kicked its ass!
