Does S.M.A.R.T still slow HD performance?

[metalmackey]

Hi

Its enabled in my bios, should I leave it? Also, is an average transfer rate of about 65mb/sec about right for a sata2 drive?

Thanks

Nothing worth loosing sleep over, I tried it all in past, killing Smart completely using the Hitachi Feature Tool, and it made no difference, but killing Acoustic Management did, esp on my Raptors but makes it SEEK louder.

Is the transfer rate ok? I can only select PIO or DMA in vista (if I untick let bios decide).

 

[helmutcheese]

That speed seems ok, but not sure what that model gets for others.

Ta,
They are Maxtor sata2 with 16mb cahe

Will diabling smart in the bios also disableacoustic management?

 

[helmutcheese]

Nope, its in the HDD's PCB if supported.

Sandra SI used to tell you if it was on and warn of performance degrades, unsure on new Versions.

I have heard that SMART will slow the drive a little, but nothing noticeable.

I was setting up a friends computer the other day and the S.M.A.R.T settings were Enabled, Disabled and Automatic? What would automatic be for or is it that not all drives support SMART?

doesn't smart also detect errors? if that is true wouldn't that be worth losing 1 / 2% speed over?

smart will report back on any hard drive values which vary from a certain "safe" range.
Itll not necessarily stop a sudden hard drive crash but in most cases it will be a gd warning in advance that something is wrong with the hard drive.
