Support M.2 PCIe based (NVMe or AHCI) M.2 SSDs (Incomplete List)
- Samsung XP941, SM951 (AHCI or NVMe), 950 Pro Series SSDs
- Kingston HyperX Predator M.2
- Plextor M6e Series M.2 SSD
- Intel 600p SSD Series
- WD Blue NVMe SSD
- PEXM2-130 is powered by ASMedia ASM2824 switch allowing you to access two drives at the same time. It does not rely on PCIe bifurcation supported by CPU, PCH, or motherboard. It supports non-bifurcation motherboards.
- PEXM2-130 allows you to access the SSDs individually or to use them in a storage pool for OS or the 3rd party software RAID configuration.
- Compatible with PCIe 3.0 motherboards and is backward compatible with PCIe 2.0 and PCIe 1.0.
Q: Can I use it as boot drive?
A: The motherboard BIOS must support NVMe SSD and support booting from PCIe in order to boot from a M.2 NVMe SSD on PEXM2-130.
In The Box
- Ableconn Dual M.2 NVMe SSDs PCIe x8 Carrier Adapter Card
- 1x low profile PCIe bracket
- 2x mounting screws

First: see our separate comparison on the RIITOP adaptor - >B08P57G1JW for full info.We compared this card along with 3 other individual cards, with numerous NVMe cards. This was a specific test done for a client with specific data management needs, so we analyzed 4 different PCIe card adaptors with a dozen different NVMe cards.Ableconn card:1. it's fast.. much faster than SSD. a good card can exceed 2.2Gb in short/small bursts).2. It's the 2nd most expensive dual card.. the RIITOP is $50 less and has better heat dissipation.3. This card overheats on larger files (we were testing 400gb+ files).4. it slows down tremendously when copying between the two slots ( a common issue on switch cards).5. Your NVMe card quality is far more important than which adaptor you use.. See our separate review on the RIITOP adaptor - it's far more detailed).The fastest card on the market is the OWC Accelsior.. but it's ~$550.. probably not the choice for the home user...The RIITOP has slightly better performance than this card for short burst copies and MUCH better performance for large file transfers (> 100GB files).Bottom line: we returned this card and wouldn't use it, because for dual card usage, the RIITOP is the better choice - less expensive, doesn't overheat, and better build quality.

このカードは1枚挿しでも問題ないとするレビューや、2枚挿ししないとフリーズして使えないとするレビューがありますが、私は後者でした。1枚挿しOKレビューは古いものが多いので、新しいものは2枚挿しが必須なのかもしれませんね。intel670p 512GBで速度を計測するとスペックの9割出てました。

I have a 5,1 Mac Pro (Mid-2012) and I bought this card per the 'Definitive Mac Pro Upgrade Guide's' recommendation.I didn't need a two slot card but this one was faster than all of the single slot cards. I put a single 970 PRO in it, and it worked fine for a few weeks, but suddenly my Mac would randomly freeze and restart itself (Shutdown cause -62). After weeks of troubleshooting I figured out that i could consistently reproduce the issue by writing large amounts of data to the drive. If I ran the 'Blackmagic Disk Speed Test' on it, it would crash every single time. With this, I did some research and found a thread about the chip that this card uses (ASM2824) and how newer versions of the cards that use it suddenly no longer work without two cards installed. I popped in a spare nvme into slot 2 and then re ran all my tests - this had completely solved the issue. I torture tested both the drives, writing tons of data to them and I couldn't get it to crash at all. Just posting this in case someone encounters the same issue. You don't have to use the second drive (although you might as well for time machine) but it just has to be there. (Also, I got full speeds* with a 970 PRO card, 2900ish)*Full PCIe 2.0 speeds of the mac pro, not necessarily full speed of the drive itself.

3枚目が Mac Pro（2009〜2012の6コアCPUで動作する1333 MHz DDR3 ECC メモリで作った）RAMDiskの速度です。2枚目と1枚目ががこのキャリアアダプターカードに積んだNVMeの結果です。この製品は古いMac Proの救世主ともいえるでしょう。

The Ableconn PEXM2-130 Dual PCIe NVMe M.2 SSDs Carrier Adapter Card is easy to install and works as described in terms of RAID. However the sequential read/write performance of NVMe cards is lack luster at best. I'm not getting actual speeds of the drive for PCIe 3.0 as you case you can see in the benchmark, where max read/write were about 1.7k MB/s with the PEXM2-130 and 3.5k MB/s without the PEXM2-130. This was observed on both a Samsung SSD 970 Pro and 980 Pro.Correction: After additional troubleshooting I determined that the issue was bifurcation. While my motherboard supports bifurcation, which is necessary to maximize read/write speeds, it was only supported on my PCIe slot 2, not PCI slot 3. After moving slots the through put was great on this card. Review modified.

I have a mac pro 5,1 with High Sierra. The reviews all said that in a 16 lane slot you could get up to 2800mps (Definitve Classic Mac Pro and others). Almost twice what you get with a simple $15 card in a four lane slot. But thats not what I got. My results were about 1600mps in a 16 lane slot. Slightly higher than my $15 card in a 4 lane slot. When I contacted Ableconn Customer Support to tell them I thought their switch wasnt working they said 1500 was the limit for Mac Pro 5,1. I still think there's some information missing but according to Ableconn for a Mac Pro 5,1 their card only gives you the capability to have a second hard drive with no increase in speed over a $15 card. Ill probably return the card.So here's the missing info: Through posting on MacRumors I found out that you have to have Mojave firmware to take full benefit of this card. Otherwise your limited to 1600mps. Its still valuable for its ability to allow you to have two cards in one slot. And at 1600 its much faster than even traditional ssds. But if you just need one card and dont have Mojave firmware, the $15 cards are a much better deal.

This card isn’t cheap but it solves a specific problem - older chipsets/boards that don’t have a ton of PCIe lanes.I have a Maximus Hero VII with a 4790K @ 4.8 and there’s no need for me to upgrade my platform yet. I have already populating the slots a 1080 TI (x16), USB 3.0 card (x1), sound card (x1) and network adapter (x1) plus an existing x4 PCIe to NVMe adapter. I wanted to add a other drive so I got another x4 adapter and put it in the bottom x4 slot. Unfortunately I don’t have enough lanes and when you put something in the bottom black slot it cuts off all the x1 slots!Enter this card. I put both NVMe drives in the adapter and put it in the x16/x8 secondary slot (where the x4 card went previously). The black x4 is empty so the x1 slots are enabled.Everything booted properly, both SSDs are working at full x4 speed (over 3000 read, close to that for write) and no drivers needed to be installed. I haven’t done a benchmark to determine if there are issues hitting both drives hard at the same time but I don’t plan to do that anyway.Again, it’s not a cheap card but solved a problem that I had that otherwise would have required me to buy a bigger single SSD or to upgrade my system. Recommended assuming it lasts.
