Product Information

You should also consider the size as well as the PCIe version of the card to make sure you’ll get a decent amount of bandwidth provided to each slot. Here are more details on why you should consider both factors: I have an 8 bay thunderbolt 3 enclosure attached which exposes 2 JMB585 based controllers which host 4x WD RED 2TB disks each.

One of the most crucial points to note is the PCIe Connector Size, the amount of PCIe lanes it occupies, and the PCIe version of the expansion card. SATA expansion cards can have x1, x4, or even x8 connectors. Each number after the ‘x’ generally indicates the amount of PCIe lanes the card will occupy. However, if you doesnt want to open your PC, then you can use external drives by using SATA to USB adapter cables. Wrapping Up While they may be inexpensive, they are inefficient and produce low scores on the performance and compatibility board. Unless you’re on a tight budget, we do not recommend that you add SATA ports to motherboard via these expansion cards.The SATA PCIe cards are often the go-to expansion card most people choose when they need more SATA ports added to their motherboard. It’s the general solution for most average users. This SATA expansion card comes in a variety of sizes and each of them comes with a wide range of ports.

If that works, then I use the 2 sata ports for 2 internal SSDs and the NVMe slot to connect with only one flat cable to a little external box with the PCIe SATA adapter. Might even look cleaner. A SATA2.0 (3Gbit/s) PCI Express ×1 expansion card, having two built-in SATA port multipliers (square chips to the left and right of the middle of PCB) that "splice" card chipset's two SATA ports into a total of eight ports. Edit: Nope, it actually does not work. I cannot find a reason, why. The ASM1061 supports PM, but does not state if CBS or FBS. Also it does not list any compatible hardware. It works with ASM1093 at least - which the card uses. I also tested, to hook the JMB321 to the one SATA Port, which does not go through the ASM1093 Port Multiplier. It yet does not work at all. I do not know, how to fix this issue. It seems, that the PM market ist crappy as hell. Very limited and totally unpredictable compatibility over all hardware... I disabled passthrough on the controllers and converted the drives to physical RDM. The VM found the disks/pool on boot and it has been running as expected since.

Apple cancelled this, now what?

Does hot-plug really has the potential to kill some hardware. Since sata is by its standards hot-plug capable, wonder if the internal sata controller has not properly implemented it. If you would have an external multi bay enclosure, whit a JMicron chip and connect it to the sata ports, you would always have to power it on first and off last to not hot plug it. Campaigns run at an idle state until you copy, read, install, or access files from them 3. RAID or Non-RAID SATA Expansion Card In the last year or two, we've had a resurgence of users asking about SATA Port Multipliers and cheap SATA controllers. Aiming to mostly replicate the build from @Stux (with some mods, hopefully around about as good as that link)

SATA hub port multiplier is another way through which we can expand the SATA slots on our motherboard.

The point is that the heatsink of the copper card is comparable in size with the switch card heatsink. Therefore I assumed that the power consumption of the switch chip will be comparable is heatsink is sized properly.

Windows typically only accesses one or two drives at a time, which means that the needs of Windows users are often relatively limited. However, ZFS often accesses data on all drives simultaneously, such as during scrubs and resilvers. This creates a lot of stress on I/O controllers, and tends to expose any problems. The difference in speed between the two versions is huge. While version 2.0 SATA ports offer a maximum transfer speed of three Gbps with a throughput of 375MB/s, version 3.0 SATA ports provide transfer speeds of up to six Gbps with a throughput of 750MB/s. – Number of Slots the Ports Has
