Title: IDE vs AHCI
Post by: AUDIODIDAKT on June 19, 2009, 05:34:51 pm
Just another Q:

IDE vs AHCI

http://expertester.wordpress.com/2008/07/24/ahci-vs-ide-%E2%80%93-benchmark-advantage/

Does anyone have experience with AHCI ?

And is there an advantage in it ?

Well, reading that, you better prepair for another install of the OS. Not me ... :)

The point is, if this is about an audio PC, I don't see how to benefit from it. You just eliminated all IO's from the OS (hahaha), and everything "we" do is just sequential.

RAID1 will do a better job for you, although it costs you an additional set of disks. The principle applied with (a proper installation of) RAID1 is nearly the same (elevator seeking).

But of coure you can try and let us know. :dancing:

Btw, I don't have it switched on, because I don't use RAID. So, as the article says, the disks are approached like IDE, and when the OS has been installed under that protocol, you can't switch it on (not outside RAID). At least that is what I get from it.

There is a work around,
I don't have to install new OS.

(really must have a dedicated audio-PC soon, real soon)

Can not eliminate that much on normal work-PC

Maybe in my case get better multitasking results

AHCI is better if you have two or more disk drives, since it overcomes some of the singletasking bottleneck of IDE.

Of course for storage, raid 1 (or 5, 6, 50 and so on) is the way to go imo. We all have huge amount of data that we would have trobule backupping every month or more.

Ehhm, but don't think RAID is a backup !!
Make one mistake (you, player software, other) and all is lost. :yes:
RAID only prevents you from hardware failure.

Besides, for me it would be sheer impossible to use it; wouldn't be able to swap individual disks (to the extend I do), and a more weak reason : not enough connections.

No, it's not, but it is a very viable solution for a multi-terabyte archive. it's not so unreliable, though (esp raid1, which is my suggestion up to 3 TB of data) where you dont loose anything, even if you unplug one disk.

PS: Roy you better enable AHCI with a SSD.
