Good to hear. (Thanks for the follow-up.) That indicates cables had been right/good all along; also that there had been no power supply anomalies in your tower/DAS, which could have explained the symptom, I can not envision that merely bad/wrong firmware in your original cards could explain it...

IF it/they really are reverse cables, is that the expected behavior? (max of one connection) Since a SAS port, and the connected cable, carries 4 physically separate Rx/Tx SAS/SATA connections [see SFF-8088 pinout], that seems odd. In addition, while it's not impossible, I've never heard/seen a...

Superficially, they will look the same; the difference is the pinouts/wire-connections. The description on that product page makes it clear that it IS a reverse breakout cable. If a 50cm long cable will suffice, This is cheaper. Disclaimer: I am not 100% certain that [SAS] reverse-breakout works...

reverse

Thanks for the datapoint.

8x 2.5" SAS/SATA subsystem in 2 x 5.25" bays is sometimes available in the used/surplus scene for ~$100-150 e.g., Intel P/N #FUP8X25S3HSDK ... would take two simple/cheap SFF8643-to-SFF8643 cables from H730p Good luck ...

I looked at the specs for your mobo and ... By using the 2 M.2 omboard connectors, yyour current two 970s are sharing PCIe bandwidth, since they are both using the z390 chipset, which relies on a 4-lane connection to the CPU. [The chipset effectively acts as a PCIe switch to share/mediate all...

I bet you need to enable Write_Caching on the drive (ie, nothing wrong with your enclosure/bridge_chip). (Your read speeds are just fine, right??) If I'm right, you need to ask OMV people WHY!! they are so "insistent" on disabling it (either explicitly, or by deceiving the user to do it [ie...

Make careful note, though, that the ASM2812 is only (PCI g3) x4 (max) upstream. It matters not that the card is "x8". "The sh*t they pull, huh??" [Johnny Utah/"Point Break"]

HPA - Host Protected Area

You got TRIMmed. (The "law" of unintended consequences)

If you've decided that a "server-class" HBA is really your best choice, I think you would be better off with a LSI 9207 (instead of a 9211). The 9207 uses PCIe 3.0 (vs 2.0 on the 9211). That means you can get the same throughput with the 9207 in your x4 slot (x16 physical) as you would get...

Whoa!! The RC-508 has (4) USB 3.0 ports. And, all this time I thought you were asking about [from the OP Subject:] "adding more sata ports". Please clarify. OK I read your subsequent discussion w/kirbyrj, and see that you had "wanted" USB. But, had you already used all 6, or 9, USB3 ports on...

It's all about getting the SATA bandwidth that you need, while making efficient use of the limited PCIe lanes you have available--and, still allow for future/further expansion. Consider, other than your 3 PCIe x1 slots, you only have a single PCIe x4 (lane) [in a x16 slot] available. I wouldn't...

Here's an M.2 adapter. It really does work. [And, it does not utilize a port-multiplier.] 2-Lane M.2 PCI-Express 3.0--JMB585 chipset ===== "Your debutante knows what you need, But I know what you want." --Bob Dylan
