Ableconn PEXM2-130 Dual PCIe NVMe M.2 SSDs Carrier Adapter Card (ASMedia ASM2824 Switch) - High-Speed 2X M.2 NGFF PCIe NVMe SSD Support for Mac & PC (PCIe x8, Non-Bifurcation Motherboard) Review

Timeouts occur when used in HP Z600, PCIe2. HP ensures sufficient power per slot and supports NVMe cards on single-connect risers. There are two 16x slots and two 8x slots (and two PCI32 slots). I installed two 2TB Intel NVMe cards in each Ableconn adapter. Each adapter plugs into a 16x slot. Linux kernel 4.19 is my main goal, but I also tested 5.7. Both see the NVMe devices, but they expire, go offline, have zero bytes, or are read-only. The second two show up in udev, but not the first two…

Ableconn PEXM2-130 Dual PCIe NVMe M.2 SSDs Carrier Adapter Card is easy to install and works as described in relation to RAID. However, sequential read/write performance from NVMe cards is poor at best. I'm not getting the actual drive speed for PCIe 3.0 as you can see in the test where the max read/write speed was around 1.7 KMB/s with PEXM2-130 and 3.5 KMB/s without PEXM2-. 130. This has been observed on both the Samsung SSD 970 Pro and 980 Pro. Correction: After additional troubleshooting, I

I bought this after finding out that my Supermicro X9DRi-F doesn't support fanout on PCIe slots, even though there is a setting in BIOS to do so. Only 1 or 2 models of this series use the same bios. I found this card after some searching. The ASMedia ASM2824 chipset on the card provides the system with two M.2 NVMe SSDs in one PCIe slot instead of using two slots. There's a slight performance hit, but I suspect it won't be noticeable in the real world. When I ran some test tools, I saw a slight

I flashed a 2009 Mac Pro to 5.1 and this little baby is amazing. I added a 500GB NVME for macos and then a 2TB NVME for my home folder and before that I used 2 SSDs in a raid on another PCI card still installed. this nvme gets 2500mb! (even without raid) Also note that I was able to upgrade to Macos Mojave, which automatically installs the firmware to read nvme. So I assumed I was stuck in macos Sierra (would allow raid drives for macos) and didn't even need raid to get those speeds (macos…

This card isn't cheap, but it solves a specific problem - old chipsets/boards that don't have many PCIe lanes. I have a Maximus Hero VII running at 4790K @ 4.8 and I don't need to update my platform yet. I've already populated the slots with 1080 TI (x16), USB 3.0 card (x1), sound card (x1) and network adapter (x1) as well as an existing x4 PCIe NVMe adapter. I wanted to add another drive so I took another x4 adapter and put it in the bottom x4 slot. Unfortunately I don't have enough strips and

My board only has one M.2 slot that supports SATA Express with a maximum speed of 10Gb/s (in testing the maximum speed is 8.3Gb/s), so it's for higher speeds practically unusable NVMe drives. However, not wanting to make a major upgrade just yet, I gave this little gem a try. I updated my BIOS to F9 "Future NVMe SSD Support" and received a WD SN750 NVMe Black 250GB 1TB to replace my 250GB 1TB VelociRaptor drives (will use them as backup for NVMe drives). The i7-5960X has 40 PCIe lanes…
