## Questions & Answers

**Q: This looks like an M.2 SATA SSD to PCIe 2.0 x2 Adapter. So it has a built-in SATA controller chip? Does it support booting from connected SSDs?**
A: Yes, there is a SATA controller chip on this card and yes it does support booting from a M.2 (not Msata), and NOT M.w NVMe (which is the new very fast storage interface).  It will boot M.2 AHCI.  You may find this forum helpful: http://www.win-raid.com/t871f16-Guide-How-to-get-full-NVMe-support-for-Intel-Chipset-systems-from-Series-up.html

**Q: I have pci-e 1x slots, will this adapter fit on those?**
A: Yes, that is what it says in the description.  Just be aware that the M.2 slots are SATA, so you cannot use an NVME (i.e. PCIEx4) SSD in this adapter, but only SATA SSDs.

**Q: Is this raid, or just dual drive? 2 port m.2 ssd to pci-e x1 adapter b or b+m key (si-pex40115)**
A: No this is not a raid controller. This is a pci-e adapter for m. 2 ssd. You can set this up for a daily backup in windows if you want.

**Q: Can this run off of a pci-e v2?**
A: Yes, it will work on PCIe 2.0

## Customer Reviews

### ⭐⭐⭐⭐⭐ PEX40115, Solid performer for years - SI-PEX40116, just installed
*by F***H on September 26, 2021*

Been using two PEX40115's for 3 years now in different machines. Anticipate using the spare I bought in yet another machine so back here again to acquire another spare. Just realized I'd never left a rating/review. It's easy to forget to do that when things work so well right off the bat and then continue to work well for so long.My use: Perfect use of my sole remaining PCI-e x1 slot to add allot of M.2 SSD storage to an already small Dell tower that's not designed to hold allot of storage devices.Jan 2022SI-PEX40116 - bought this long ago and only today found a system to put it in. Other systems only had x1 slots available. At first it didn't work at all but that might have been a seating problem. I have 4 2TB SSD's on the card. Removed 2, started working. Added the other two back and carefully/firmly seated the card - now all 4 work. These don't seem to be available any more but just in case someone gets one and decides to fill all 4 slots, don't be dumb like me and think too hard about the mounts. There are no instructions and it did not dawn on me that ALL 8 of those tiny screws were needed. Two screws for each SSD. One to mount the spacer and the other to hold down the SSD.I had ended up using some longer screws to secure the SSD. Looking from the side it just didn't look nice and neat. I bought a spare recently and practiced some more on it when I realized if I used all 8 screws then it was super simple to mount all 4 SSD's neatly.

### ⭐⭐⭐⭐⭐ If your PC supports booting to a PCIe add in card, you can boot to a very fast M.2 NVMe SSD!
*by M***S on August 20, 2019*

With the prices on M.2 NVMe chips falling through the floor, I want to add an M.2 NVMe chip to every computer I can.Unfortunately, only the newest motherboards have PCIe M.2 slots. I first tried using this board to install an M.2 chip in a Dell Optiplex 9020. When I installed WIndows 10, the installation saw the chip and allowed me to install to it, but the joy ended there, it was not bootable! If I install WIndows 10 on another SATA disk, boot to it, the windows installation will see the M.2 chip, it is considered a Mass Storage Device, but no way to make Optiplex 9020 boot to it.Next, I added it to Dell Precision T5810, now this was a totally different story! As before, I could install Windows 10 to the M.2, but then would not boot. I then updated the BIOS to the very latest, once it rebooted, voila! Windows 10 booted from the M.2 chip on the adapter board!After Windows 10 was up and running I ran Crystal Disk Mark speed test, was only getting about 1500 MB/s read speeds, not bad, but still way below the rating of the M.2 chip. Turns out I had installed the PCIe M.2 adapter in a slower PCIe slot, moved it to a faster slot, rebooted and ran Crystal Mark Disk check again, this time 3400 MB/s, awesome!Moral of story, make sure your PC or motherboard will boot from an M.2 chip mounted on this board, then buy it!And for a great deal on what has so far has been a very impressive M.2 NVMe chip, I can just say 2 words, Inland Premium. Search Amazon for Inland Premium, I chose the 512GB version, have installed at least 10 or more of these, working great so far. Or, you could go for the chip made by the company famous for its failed folding phone and pay over twice as much and get just marginal better performance, choice is up to you!

### ⭐⭐⭐⭐⭐ Exactly what I needed!
*by Z***N on April 11, 2019*

The motherboard in my computer has, what I would consider, a few poor design choices when it comes to the interfaces used by the two available M.2 slots and what PCIe slots are disabled depending on what you have plugged in. Realistically, it's a problem that almost no one is going to run into and is only caused by my unconventional hardware setup. I call it "poor design" because further research indicates it wouldn't be an issue with every other similar spec'd motherboard I've looked at. My options were either buy a new motherboard, a non M.2 SSD, or find an adapter. Not only is the adapter the cheaper option, but it also gives me the ability to add a 2nd M.2 drive down the line.I have the option of using 2.5" SSDs, but I like to keep the amount of cables in my case as low as possible. That being said, there is some, at least on paper, degraded performance. In my configuration, this card is plugged into a PCIe 2.0x1 slot with a max throughput of 500 MB/s. If I were using 2.5" SSDs connected to my SATA III, I would be capped at 600 MB/s. I haven't actually benchmarked this, but I don't really notice a difference in speed vs. standard SATA SSDs. Furthermore, the SSD I have on this card is used almost exclusively to store video games, so it's just not that important. The only other thing I can think to mention is that you will lose a second or two when booting up your computer as the adapter boots its bios first to set the drive to be detected as SATA devices.
