There are four SATA data connectors on a new main board. Usually I just plug in to them as convenient disregarding the numeric designations. Is there a proper order in which to connect two or three drives and what is it. Neither the board manual or my google searching have been any help. The connectors are labeled:
SATA3 _A1 SATA3_1 SATA3 _A2 SATA3_ 2
Can someone tell me what order to use them in or if it matters? They are labeled so it would seem there certainly must be a reason ... * Bob*

order usually matters little.
Given there are only 4 I would expect them to be connected to the same sata device, but it could be that there are 2 2 port sata devices and the labeling denotes which of those 2 port devices they are connected to. The labeling is rather odd for it being 4 on the same device.
What is the part number of motherboard?
ok. I did a quick google, and if this is an asrock motherboard then the A* ones are on their sata controller (whatever vendor they chose), I avoid all sata controllers that aren't made by Intel, AMD and/or LSI. Any of the other vendors that make only 2/4 port controllers are usually a disaster waiting to happen, so if the A* ones are a ASrock supplied sata controller and not an AMD/Intel or LSI then avoid that one as much as possible.

° It's an ASROCK J3455-ITX. for some servers that never get shut down I try to keep the power requirements as low as possible, I've measured these and they run below 50 watts when idle which is most of the time since it's home usage. They are low end but work well enough ...
i also see in the manual: Storage • 2 x SATA3 6.0 Gb/s Connectors, support NCQ, AHCI and Hot Plug • 2 x SATA3 6.0 Gb/s Connectors by ASMedia ASM1061, sup- port NCQ, AHCI and Hot Plug
I have wondered about the SATA connector designations and their use for a long time and appreciate the information. I'll just go on as in the past then, it matters not.
Thanks
Had you been using the A* connectors and did they work reliably?
In the past I researched the different sata chipsets, and I don't remember if I found anything definitive on the ASMedia ones. I have personal experience with the marvell ones and they were junk (4pt, pcie-2lanes) as they would randomly drop all 4 disks under heavy load (or smartctl commands), it did not act like a driver issue since the driver was the generic AHCI driver and worked perfectly fine the entire time with the AMD chipset sata ports.
