IO CREST8 Port SATA III to PCIe 3.0 x1 Non-RAID Expansion Card Dual ASM1064 Genuine 6.0bps with 8 Drives Attached Low Profile Bracket, SI-PEX40165

I installed the 6-port JMicron version of the card on an ASUS H770 motherboard. Win 11 recognized it as "Standard SATA AHCI Controller" with the standard AHCI driver installed with it. The computer could only read one disk. I downloaded and installed the JMicron Win 10 driver from the Syba website. It then showed as a "JMicron Controller" in Device Manager and sees/reads/writes to all six disks without a problem.A few issues I had to work through - perhaps not obvious to a newby like me. When I first booted up the computer with the controller, the device appeared as a Standard SATA AHCI Controller under IDE ATA/ATAPI Controllers. My motherboard sata controller also shows as a Standard SATA AHCI Controller, so make sure you install the JMicron driver with the correct controller (the 6-port controller will display which PCIE port it is connected to). When I rebooted my computer with the JMicron driver installed, the computer went into a "Preparing Automatic Repair" boot loop. I restored the computer to a restore point prior to installing the driver and changed my BIOS boot mode from UEFI to Other OS. I then re-installed the JMicron driver and the computer booted fine and read all six disks.

Installed it and it originally only detected 2 drives. Thought I just got a defective card since I bought it from Amazon Warehouse. Ordered a second one (brand new) and it did the same thing. Figured it must be driver-related and googled the product (SY-PEX40167) and there was a link to the Syba website to download the drivers for this card. Installed them and rebooted and it works perfectly so far (6x 14TB HDDs + 1 1TB SSD so far). Maxes out at ~850MBps, which is the max speed for a PCIe X1 3.0 slot.

I use all four ports on the card and so far no issues. The last expansion card I had would lock up randomly and show IO errors, but this brand has been working great so far.

1. There is no manual.2. I have no idea if it supports optical drives. It is not supporting mine.3. The cables sent with the drive are trash. I thought I had somehow lost 2 drives because they would not show up. I have a total of twenty drives (counting the optical drives) directly connected. That is part of why I bought the io controller.4. There is no customer service apparently in the USA. The only telephone number for IO Crest is in Hong Kong. I do not have international service on my telephone.5. The website is in Chinese (I do not mind as we do all our websites in English but most offer additional languages. This one does not). I do not read Chinese of any flavor.6. The website does not list the card I purchased from then less than 1 week ago. I found the page with IO controllers. They provide the model number in Roman letters, my model is not present. I had hoped to find the model and try tracing to a manual.7. The card on boot up did something to my computer, I do not know what. It must have changed the BIOS on the motherboard somehow. I was going to go back to my old IO card until I could get new cables but MY COMPUTER WILL NOT EVEN POWER ON WITHOUT THE CARD INSTALLED. I have to leave it installed to do anything. The computer powers on fine with the card installed. I checked if several times. Card in, powers on, remove card nothing (at first I actually thought the motherboard or CPU had failed when I tried switching back and poof nothing). Put back in the card, powers on. Remove nothing. I did this test 3 times. My computer now requires this card. That is a MAJOR PROBLEM.I am purchasing new cables, hopefully they will fix some of the problems. If they do I can connect the optical drives from my motherboard SATA ports.I might possibly raise the rating if the new cables I am ordering work. I really do want this card, heck I was considering purchasing a second one. The motherboard problem is not insignificant to me. The lack of support for optical drives is not insignificant. I now doubt I will be making that second purchase for my main disk tower (home built NAS).I admit my hardware is older (ASRock Z87 Extreme 4 with Intel I7-4770K) but modifying the BIOS especially without warnings to the customer prior, hopefully prior to purchase, is simply not acceptable.Edit Added:I have now purchased a new set of cables for one of the 3 SlimSAS connection points (They are expensive so I only bought 1 set to test first). The original cables gave me 1 connected drive on each of the cables for a total of 3 SATA drives instead of 24. The new cables increased the number of connected SATA drives by 2 to 3 for that SlimSAS connection. As I was connecting up 8 drives, I would have expected 7 more connections.The fact that I got 2 more connections suggests the card has a problem. I would not be returning it had the results not changed as it may have been incompatible with other hardware. With no manuals or other information, and the listing stating it was compatible with Windows 7, 8, 10, 11, I could only assume it would work but it was a guess. Now I am sure it is due to a problem with either that specific board or that line. I am returning the board for a full refund and have ordered a 16 SATA 3 connection I/O card.I worked in a main frame systems shop and saw similar cards (I do not know the manufacture) is use all the time. I had hoped to avoid the clutter all the SATA cables would cause. I will accept the clutter now.

After having issues with a similar card that used a Marvell chip, this ASMedia-based card was plug-and-play on my Ubuntu 22.04 Linux machine with an Asus B650-based motherboard.

No Additional Drivers RequiredI attached my 7 SATA drive cables to the card, installed the card into an available PCIe 1x slot, booted Windows and the card (all 8 SATA ports) were immediately recognized!Windows installed 2 instances of the "Standard SATA AHCI Controller" and all 8 ports were recognized.Windows added the drives immediately upon bootup and were available from File Explorer and Stablebit Drive Pool.I would highly recommend this quick and efficient controller.

I purchased this as an upgrade for my Unraid server. I went from 4 drives to 10!I love that there was no configuration needed. It worked straight out of the box. My server is an old HP SFF and space is very limited. This card fits nicely. I'm extremely pleased with this card and look forward to many years of use.

Mine didnt work at all. Only saw my dvd writer and not one ssd or hard drive. Return was fast and easy.

If like me you're having trouble choosing a pci sata card from all the mixed reviews out there, I can say that this works just fine for me on an MSI z97 motherboard. Got a DVD drive and SSD working in plug and play. Just using the SSD for file storage but read and write speeds are just fine.

Works fine. Plug and play with Win10. Very boring. Very bright LEDs though ;}

Does the job. No problems with drivers. Good card

Pros:1. 2 extra sata port for sata devices.2. When using one port only, the speed is very close to the onboard sata port.Cons:1. first one arrived DOA.2. when using both ports simultaneously, even the 2nd one is a DVD Burner, the transfer rate dropped to 40mb for the HDD.3. Even though it's internal card connected to internal devices, windows 10 shows the devices as removable. so have to be very carefully not to eject them accidentally.

I needed something to be able to plug more hard drives into my unraid server. Added it to my pc and it immediately picked up every drive plugged into it and hasn't had an issue. Speed seems to be the same as plugged directly into the board, but as I am using this for file storage it only has spinning drives so I can't say whether it is as fast with a SSD. Overall I would recommend this for the price and ease of use.
