Pros: Long cable for large case.

Cons: Used 5 for my RAID-5 settings. Windows took a long time to boot with 2 of HDD LEDs blinking. (I have a 5-bay HDD cage so each hard drive has its LED). After Windows launched, those two HDDs show "Ultra DMA CRC Error" which never had before. I tried rebooting several times and booting Windows still took long with the same issue. Replaced with my old cables and the issue was gone. 2/5 = 40% failure rate.

Overall Review: Do NOT buy.
