It was just listed as a SAS3 to SAS3 cable. I don't think there was any mention of connector, just pictures, which were accurate.

My drives passed a full badblocks test no errors. I save the smart data before and after and diff them. No increase in ECC errors, and "grown defect list" is 0 for both. If I'm feeling paranoid I could run a latency test sector by sector that tries to find reallocated (or just troublesome) sectors. Sort and long selftests also passed.
Now the question is do I get 2 more of these, or 2 of another model to reduce the risk of any model/batch specific issues.

I ordered a couple of these and was wondering about the cable myself, since the pictured cable wouldn't actually connect the drive to the card without a backplane, and if you already had a backplane, you probably already had a card and cables.
I didn't particularly care, since I already have a backplane, card and cables.

if it was somehow miraculously a regular HBA card (not a hardware raid) and also had 2x breakout cables, i would have jumped out the deal, only to get the very marginal upgrade from my current HPE H240 (it's still 12G SAS, but uses the older SFF 8087 cables from is limited to around 10G max speed instead of 12G). But that would be asking for like... three unicorns of a deal all combined into one.
For the card from the eBay listing, that's pretty much all you can use it for. Without cache, it sucks at RAID.
The JBOD mode presents the disks just like an HBA. The only difference is that the RAID driver is used by the OS, instead of an HBA driver. TrueNAS fans will tell you that the HBA driver is more tested than the RAID driver, but this is really no longer true, at least as far a TrueNAS SCALE is concerned.

It looks there is a rise module installed on my card. I think it's a cache module. Anyone else also has one installed?
The only thing that can be plugged into the connector next to the heat sink is a cache module. You can check the status by entering the card's BIOS, or using storcli.
So how many people here that bought on this offering had their card come with the cache installed and how many didnt? Without the cache, it sucks as a RAID card but with the cache, should be pretty decent? Now if we can get the capacitor battery back up for cheap, that would make it a great deal 
I have one of these in barely used condition (w/o a low profile bracket), not sure if it's compatible with the above but I could let it go for a good price in case anyone is interested.So how many people here that bought on this offering had their card come with the cache installed and how many didnt?

These are some expensive raid battery back up...lol... The question is how long are they able to keep the data back up in the cache... longer than a ups?
Yes, generally longer than a UPS. But if you have a UPS, the data can be written and the system safely shut down so that's usually the route I go vs a battery.
Yes, I got this with mine. I am still confused about whether that is supposed to have battery backup.
