0.75m 30AWG Internal Mini SAS 36pin (SFF-8087) Male w/ Latch to SATA 7pin Female (x4) Forward Breakout Cable - Black
Serial Attached SCSI (SAS) is a high-speed data storage interface designed for high-throughput and fast data access. Intended primarily for data storage centers, the SAS interface is backwards compatible with SATA. This allows the user to mix more expensive, lower-capacity SAS drives for applications that require faster data access and higher reliability, with lower-cost, higher-capacity SATA drives for applications with lower access speed requirements. Monoprice carries a full line of quality SAS cables with connectors for every possible application, both internal and external.
This 3/4 meter long cable uses 30 AWG wires and is intended for internal use. It has a single 36-pin SFF-8087 male Mini-SAS plug (with locking latch) on one end and has four 7-pin SATA female plugs (with locking latches) on the other, allowing you to connect four SATA drives to an SAS controller. This is a Forward Breakout cable, meaning that it is intended to connect to a host/controller on the SAS end and to drives on the SATA end.

PROS: Very reasonably priced as compared to other SAS breakout cables. Monoprice chat would only commit to saying that the cable would reach at least SATA 1.5 speeds, but my limited experience with the cable suggests that it won't impede SATA 6.0 performance.
CONS: No deal breakers. The cable's construction is much less robust than typical for Monoprice. Also, it would be nice if the cable was offered in a shorter length and with right angle SATA connectors.
The test unit is an AS-Rock 880 MB with an AMD 965 quad core processor and 16GB of DDR3-1600 ram. The drives are five 3TB Seagates in a Z1 configuration (FreeNAS version of Raid 5).
I hooked everything up and did a scrub so that there would be no time difference for fixing any errors. There were none so I rebooted the machine and ran the scrub once again, the time was within a minute of the first run at 2hrs 34min. I then disconnected all the drives from the motherboard and hooked them up to a Dell H310 controller (flashed to work with FreeNAS) and two of these cables. I used 2 connections on cable 1 and 3 connections on cable 2 and ran the scrub again. The time was 2hrs 36 minutes. Since the drives are SATA 3, the motherboard is SATA 3 and the controller card is SATA 3 the only difference was the cables. If the cables cause the system to be 2 minutes slower after 2 1/2 hours I really can't complain and that difference probably falls within the margin of error anyway. It is my opinion that my system can't overload the capability of these cables. That isn't to say if you ran the same tests with SSD drives there wouldn't be a difference since the transfer rate of SSDs is so much greater but there seems to be no degradation running 7200 rpm mechanical drives.
PROS: Inexpensive, decent quality, locks in.
CONS: Stiffer than I would like but I can live with it.
PROS: Order arrived on time and in good condition.
PROS: the latch, it click and hold on to the drive, regular cable don't have this option
PROS: Well-built and inexpensive, a rare combination. They get the job done. Both ends clip on securely, and the drive end cables are labeled clearly P1 through P4.
PROS: Cheap cables.
CONS: Not rated for SATA II or SATA III transfer speeds.
PROS: Cheep, works great.
CONS: When the cable breaks out to the individual SATA cables it's a bit small. I think it matters, but whatever.
PROS: Works as expected.
CONS: Doesnt make coffee
PROS: High Quality
PROS: Low price
CONS: May have transient errors. read review below
kind of flimsy
