Currently have the cables that I got for 25 rupees each from a computer shop while buying hard drives.
I’ve been running into issues with a few of these cables now. They work well for a while but because they are in a cabinet which runs 24x7 (my NAS+homelab), it seems they just go bad after a while causing HDD restarts and data corruptions.
One my HDD start-stop count went over 7k due to these bad cables.
The cables that came with the RAID card seems to be superior quality. But I have half my drives connected to RAID card and the other half to motherboard for redundancy.
Irrespective of cables if you are building something to work 24x7 - you need to monitor the stats. Cable could be faulty you need to secure the connection properly, anything a little bit loose could probably yank the connection.
Are you talking about the power or the data cable ?
Get it from motherboard box from PC store or old computers. It is better to buy used than new in these cases as getting good quality cables other than HDMI is almost impossible in India. Even getting a laptop power cord, the club shaped one, is almost impossible in good quality. I finally asked my laptop repair guy to sell me an old original cable from an HP charger.
Getting cables from motherboards is a good idea, I have many such cables lying around that came with motherboards and never used. you can check locally or someone from TE can help.
