Do I need SATA 3 cable

skanungo said:

I have recently purchased a SSD which supports sata 3. My motherboard also supports sata 3. But I can't find any sata 3 cable in the shop. So I want to know whether sata2 cable will be fine for my SSD or not. I mean, will i get the full speed of SSD or it will be slowed down due to sata 2 cable? Thanks

Hi skanungo,

YES, SATA 2 & SATA 3 differ in data transfer speeds, SATA 3 is at 6GB/s whereas SATA 2 is at 3GB/s but this is only dependant of your hardware, NOT the cable. Therefore it should be completely fine to use a SATA 2 cable between 2x SATA 3 Devices. SATA 2 cables can handle 6GB/s speeds.

If it is bothering you that much take a look on Amazon: Amazon.in: SATA 3 cable

Let me know how it goes,

Write speed should be around the same and your Read speed.

SATA Speeds
SATA 1 (1.5Gb/s) speeds are from 1MB/s to 150MB/s
SATA 2 (3Gb/s) speeds are from 151MB/s to 300MB/s
SATA 3 (6Gb/s) speeds are from 301MB/s to 600MB/s

Write speed can be improved by defragging your Hard-Drive. Please download Defraggler: https://www.piriform.com/defraggler and Defrag your Hard-Drive. Then use the built in 'Benchmark Drive' tool in Defraggler and then run the Disk Mark test again and post your results.

Also please disable Windows Defrag Tool:

• Start > Type dfrgui in the Search bar
• Highlight your SSD and click on Configure Schedule
• Make sure Run On A Schedule is unchecked. If it’s checked, uncheck it.

It is an SSD, don't defrag it.

What brand/model it is?

Do SSD's not require defragmentation?
