Impact of IAA on HDD Performance

chainbolt · 5th February 2003, 2:43 PM

IAA = Intel Application Accelerator. This is a re-post from a different forum, but I think it fits better into the storage forum, because the question about the usefullness of the IAA pops up again and again.

The ABIT IT7 Max 2 let you run your parallel ATA HDD from 3 different controllers. The tested HDD is a 40GB Maxtor D740X.

(1) 845PE IDE controller
(2) the onboard HPT 374 ATA 133 RAID controller (as single disk)
(3) with the ABIT PATA to SATA adaptor from one of the 2 SATA channels

Look at the comparison! Winbench 99 is based on around 9 business and high-end content creating applications. This is real world performance. Important is the huge difference the Intel Application Accelerator has on application performance. I always thought the thing is evil, but this is not true at all. It seems also that the WB99 Business Diskmark test has a little problem with the 845PE controller, even when the accelerator is installed.

my 800jb arrived today, thanks to Xenon and TheImp

next few days gonna test 4 x 800JB on rocketraid404 in raid 0, 1+0 and 5 with and without IAA

Looking forward to this, the more data we collect about this IAA thing the better.

MS Excel, a simple chart utility is also included in MS Word.

doh don't have either... stopped using MS Office after MS Office Pro 95 hehe changed to Sun Star Office 5.2

Star Office and Open Office have similar options

on the thread topic i have not noticed significant real world increases on workstaions i have installed IAA on. Although these results make me think i possibly should have.

Depends on how you bench

Winbench 99 is basically a HDD bench, but it is using applications, means close to real world (much closer and relevant than sandra or HDtach which are pretty useless to bench a HDD).

As IAA is working with caches or something, it might be the WB 99 is somewhat exaggerating the impact.
