SATA & IDE

Please can you help when I pack a file up with winrar which is about 300meg if the HHD is connected to the IDE it is about 1min 30 secs faster then when connected to the SATA is this about right

many thanks

SATA should be as fast, or even faster…

When connecting your drive to the SATA interface, do you use a converter to do so? These convertors are known for lowering the hdd’s performance…

Any current hard disc can easily write or read 300 MBs within 8 - 10 seconds.

If you speak about minutes, then the compression progress is taking all the time.

The interface should not affect the speed at all. If it does, then some of your drivers are baaaaaaaad

Yes, every hdd can do about 30mb/sec without too any problems (assuming the drivers and settings all are correct), but it seems like these PATA->SATA convertors can be the cause of some problems. We’ve had a couple of those at the office (no name convertors, pretty cheap stuff) and they made the performance suck. That’s why I suggested this to be a possible cause… :wink:

This could be a driver issue, yes, as he is doing the same process twice, but when connected to SATA there is quite a differnce in speed.
If the compression goes slower when connecting the HDD to the SATA interface, there must be some explanation for the lower availability of CPU cycles. Maybe UDMA isn’t enabled for the SATA channel?
