Cable Matters Internal Mini-SAS to 4x SATA Forward Breakout Cable 1.6 Feet

Board: asus tuf gaming x670e-plus wifi Cpu: ryzen 9 7900x

I had originally ordered a set of SAS to SATA Forward Breakout cables on ebay along with my order for an LSI SAS 9207 Sata/SAS HBA hard drive controller card. They were definitely cheaper on Ebay, and the ones from Ebay worked perfectly fine for 6 months until I decided to upgrade my Unraid server to an all new Ryzen build. During the the re-build, when disconnecting the LSI HBA card, I accidentally pulled part of the black sleeve covering the SAS connector stem area. It appeared to be cosmetic only. After firing up the new build everything booted fine and seemed stable. Data copied well and it all appeared to be great.... until I tried to validate partiy. I quickly started to experience consistent parity errors with different error counts every time I validated. It was random, though SMART drive tests all passed fine. After many hours of investigation and troubleshooting, isolating drives, etc....I finally decided to just try replacing cables with these ordered from Amazon (for fast Prime delivery). To my amazement parity validated perfectly! These immediately resolved all of my stability issues, and parity was able to be rebuilt and validated numerous times (to confirm). I had heard that the Unraid parity process could be sensitive to cable issues, but wow after 30+ years of building PC's I was quite suprised but am happy to have gotten a quality cable, delivered quickly!

worked great.

Great durability! Great product!

This is required by the Adaptec Raid 6405 4-Port Pci-Express 2.0 X8 SasSata Raid Controller Card Ad640 for connecting SSDs to the RAID controller. Distinguish between Forward and Backward breakout cables. Also consider the number of drives being used.
