IO CREST 2 Port SATA III PCI-e 3.0 x1 Non-RAID Controller Card Jmicro Chipset SI-PEX40148

A side-by-side comparison of two I/O Crest controllers. The ASMedia 1064 controller is smaller and includes status lights. Although it is supposed to be a faster PCIe 3, my tests revealed that it is slower than the Marvel 9215 controller. New drivers and utilities may be able to assist. The heat sink on the Marvel controller gets very hot. The ASMedia controller does not have a heat sink and does not produce any heat. br> A driver CD is included with both controllers. To install the controller, you must first navigate to the appropriate folder. The remaining folders contain USB drivers and other controller-related files. Installing those is not a good idea. Both controllers' instructions are a bit perplexing. br> I only use the extra controller for a backup drive and hot swap bays on the front panel. After finally booting through bios, it took a few attempts to get the ASMedia controller to work properly. RAID mode is enabled on the MSI Z390 Gaming Edge. It was a lot easier to use the Marvel controller.

In Windows 10, this works fine. Before you even get to the desktop, the drivers are already installed. When you use the two ports at the same time, you'll get the full speed of the PCIE Gen3 x1 interface, which is the bottleneck here. To truly feed the two SATA ports, you'd need around 10gb/s on the PCIE bus slot (which would necessitate an x2 slot). One SATA port on a PCIE x1 slot delivers full speed of 530 MB/s. 540MB/s, but if you use both (aggregate and striped/RAID0), you won't get the desired 1000MB/s; instead, you'll be limited to around 900MB/s - Because a PCIE x1 port can only handle 8x10003 bits per second, or 8 Gbits per second. The important thing to note here is that the advertised Gen 3 support is accurate; it is not limited to Gen 2 as many of these two port cards are. So far, this card has performed admirably in the PCIE x1 slot. Performance tests with one Samsung 950 Pro 512GB drive (left side) and two drives striped (right side) for ASS-II are attached. This should answer all questions: SD, CrystalDiskMark, and a simple AJA test of 1GB (file per frame). This is an excellent PCIE x1 GEN 3 card!br>br>Test platformbr>Windows 10 Probr>ASUS Strix- E z490br>Intel i9 10900Kbr>64GB DDR4br>This card is in the PCIE x1 slot that is farthest from the CPU. NVMe direct to CPU (10500GB/s) and through the PCH z490 chipset are crammed into all of the remaining slots. The PCH chipset (the usual x4 Gen 3 DMI 3) has a PCIE x1 slot. There is no other significant I/O being used (limit of 0).

PCI-Express 2 Port SATA III e 3. 0 x1 Non- SI-JMicron RAID Controller Card with JMicron Chipset PEX40148. This IO Crest controller takes the place of a Vantec UGT-based controller. ST644R 4- Under heavy load (writing), the port SATA controller would occasionally fail. It can connect to two drives and keep them writing and reading at their maximum speeds. br>br>Only time will tell if the IO Crest controller experiences periodic failures as well. There is hope because the chipset is made by JMicron, not Vantec. br>br>I didn't give it five stars because the JMicron chip has an annoying display during bootup that lists the disks connected to the IO Crest card and displays the JMicron company name twice; it's only a few seconds long, but it makes me wonder about the rest of JMicron technology. 5 days later: br>br> The IO Crest card continues to perform admirably, having successfully transferred over 2 TB of data and thousands of files.

I was able to connect two more drives without any issues. There is no need for any additional drivers or equipment. In a PCI- e 3. Even when both slots are in use at the same time, the speeds are identical to what I was getting from my SATA ports. (However, these drives only spin at 5400 RPM. ) br>br>My only gripes are purely surface-level. It adds a few seconds to boot-up time and displays a screen with a list of installed drives. I'm not sure if this is required, but it's inconvenient. There are also a few LEDs that are completely unnecessary and very bright. The lights are very noticeable and annoying in a dark room, and I have this installed in an old PC that I use as a sort of NAS/HTPC. I would give this 5 stars if it didn't have any LEDs in it.

2 Port SATA III PCI-E IO CREST e 3. 0 x1 Controller Card (Jmicro Chipset), SSD was connected to this card via a PCIe x1 motherboard connection to improve SSD performance. Although the card worked, there was no improvement in SSD speed when compared to connecting directly to the motherboard's SATAII port.
