SilverStone Technology ECS07 5-Port SATA Gen3 6Gbps Non-RAID M.2 PCIe Storage Expansion Card, SST-ECS07

Needed this since my motherboard only had 4 SATA ports and I needed 9, worked out perfectly. This basically works like an HBA and each drive is shown to the OS individually which is what you want with a zfs truenas setup.

WARNING: towards the end of this review i list a really troubling concern about other products that are suppose to do what this one does. please be sure to read it!u may have heard that many of the newest motherboards don't always work well with the pice sata expansion cards. that was certainly my experience with my asus x670e-e motherboard. mobo manufacturers have also decided to limit the number of sata ports their boards offer to only their more expensive boards. well, this little product is the answer to all of those problems. it is truly plug and play for windows 10 and 11. i haven't tested it on 7 but i'd guess it works on that too. there are no drivers that need downloading and no changes that need to be made in your bios, as long as u have not disabled any of your m.2 slots. i recommend putting this into one of your gen 4 m.2 slots so that u don't chance making your gpu run in x8 mode. WARNING: there are other much cheaper versions of a product similar to this one that are suppose to do the same thing but i read too many reviews of it failing and burning out that m.2 slot on the motherboard. so i went with this expensive one. i would advise everyone else to do the same. i have tested my hard drives with them connected through this device and with them connected to the motherboards native ports and i have seen no speed difference in crystal disk mark. so, i highly recommend this product. i have read some complaints about how the blue leds are too bright on this product. i keep my pc where i can not see them and it will eventually have solid side panels on it when i get finished with it. so i can not speak to that issue but, it is something to keep in mind.UPDATE: still works flawlessly after a little over a year of use. higly recommened!

Used this in a Mini PC build where I needed SATA ports, but had an extra m.2 slot to use. Plugged this in, added the SATA cables and drives, and they all showed up without an issue.It's not the ideal way to RAID a bunch of drives up, but if you just need added space for a few random drives, or you're using some sort of NAS software that likes just a bunch of drives (UnRAID or TrueNAS), these will do the job nicely.Other reviewers mentioned that it's smart to plug your drives in before mounting the m.2 drive, and they're right. The main reason is that heat sink on the side isn't really bolted on securely. Does the job, but it can move based on how your case and motherboard is setup. Doesn't affect functionality, but it is a tinge annoying.This is the higher-end of these, because Silverstone is a name brand, not just a Chinese rip-off. Bought for that reason, it's working well, and I expect it to continue to do so.

Recently built a new NAS and wanted a low profile way to add more SATA ports without sacrificing my only PCIe x 16 slot. So far so good, ran a parity sync with 3 drives attached and sustained roughly a 250+MB/s read speed, per drive, for several hours without a drive dropping offline. I was concerned loading this adapter up and hitting all the drives at once would be an issue. I'll update my review in the future once I do just that and test it out. So far so good!Pros:- Has metal shroud for rigidity to reduce the chance you accidentally snap the PCB when inserting your cables.- JBM585 SATA Controller with a Heatsink to keep it from burning up.- Made by SilverStone, a reputable company.Cons:- Slightly more expensive but I think the pros justify the cost.- Blue LEDs that are brighter than the sun.

I am growing increasingly annoyed with the lack of SATA ports on modern motherboards. Some x670 motherboards only have TWO for christs sakes!Additionally, with large graphics cards, mainstream motherboards often have most of their pcie slots blocked, so you can’t go the old SAS card route, either.I did not know adapters like these existed, of course I bought two for the coming SATApolcalpyse. They work great, plug and play, no issues at all. All 5 drives show up and format/read/write perfectly.My only problem with them are the super bright blue leds that indicate the ports are working/used. Gonna tape over them with electrical tape. Other than that these are incredible.Silverstone is looking out for file copying enthusiasts like me.
