![]() Simultaneous test of 6GB eMLC on 12GB controller + 24 port SAS expander. Here is a test of my SAS setup, 16 drives on expander (expander slows things down, but results are shockingly better than you would achieve with intel southbridge). The only reason where you might not use SAS is when BIOS doesn't allow booting from SAS drive (but todays everyone boots from NVME anyway). Yes you might have to buy appropriate SAS cable (it's another topic, cheap on ebay from china). SAS controller on your motherboard is probably LSI using 4 pcie lanes - throughput was the same if you use 1 or 12 SAS drives (i lost the link to that blog I made). the 3670 onboard sata hdd power mini 6 pin connector is Dell proprietary. I recognize that I would need a 6-Pin SATA Power to 4-Pin Male Molex cable if this is doable. Serial-attached SCSI or SAS and SATA are both technologies that use thin cables to serially transmit data from a computers motherboard to and from storage. Although SATA connectors are described as a single port or connector, SATA. Re: My question pertains to using an available on-board SATA HDD power connector. Tests I've done show throughput drops proportionally to number of SATA drives connected to southbridge and results were horrific for 6 drives used simultaneously on Intel southbridge. In other words, your PC connects through two SATA ports, one on the drive and another on the motherboard. Usually SATA connector are part of Intel southbridge. Most of the time, on a motherboard, you will find all. The notches, edges, and shape of the SATA port are designed to secure best the SATA cable that plugs in so that they do not slip out easily. MSM software (or BIOS) can show you negotiated speeds.Īre there drawbacks using SAS connectors instead of SATA 3 ones for SATA 2 and SATA 3 drives? In other words, if the motherboard has both SATA 3 and SAS connectors, what is the reason, if any, to use SATA 3 connectors for SATA drives? A SATA port is a small port measuring about 1.5 cm x 0.4 cm in dimensions with precise notches and a highly recognizable L-shaped seven-pin connector. They will negotiate the speed, slower device wins (12G sas ctrl will lower speed to sata 2 drive if needed) or drive will lower speed to older SAS controller. Can I connect SATA drives to SAS connectors?ĭoes the 6 Gb/s transfer rate means that I'll get an equivalent of SATA 3 (which is important if I use SATA 3 SSDs)?
