hello friends.

 

I stand in the forum, my name is Pedro.

 

just bought this hdd and I have a bad performance.

 

show images:

use the latest AMD driver:

system operative windows 7 x64 full update.

 

where is the problem?I look forward to your help.

not all sata cables are worth?

unfortunately no they are not.

 

Yes, there is a real difference, it's the data transfer speed. SATA 3 has the potential to double the speed of SATA 2. Like malmental posted, the cables can be used interchangably. Here are the possible scenarios you'll encounter:

 

1. Device and mobo support SATA 2 - use of a SATA 3 cable will not get you the 6GB/s due to physical limitations of device and mobo.

2.Device and mobo support SATA 3 - use of a SATA 2 cable will not get you the 6GB/s due to physical limitation of the cable.

3. Device supports SATA 3, but mobo supports SATA 2 - using either SATA 2 or 3 cable will result in 3GB/s.

4. Device supports SATA 2, but mobo supports SATA 3 - using either cable will result in 3GB/s.

5. Device and mobo support SATA 3 - use of SATA 2 cable will result in 3GB/s

6. Device and mobo support SATA 3 - using a SATA 3 cable will get you the 6GB/s

SATA 6Gb/s Cabling

In the transition to SATA 6Gb/s, it will be important to use high-quality cabling.

Problems may be related to the use of cables made from marginal materials that

perform at the edges of SATA 3Gb/s tolerances, which could become a failure point at the faster 6Gb/s signal rates. SATA-IO therefore recommends that only high quality

cables and connectors be utilized for SATA 6Gb/s.

 

In otherwords, if it's a crappy cable it may not be able to handle peak and/or sustained throughput.

thank you very much to todospor aid.

 

the solution was set bios to default values​​.

 

reconfigure bios by hand.
