Samsung SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive

Review: Works with RPI5 and Ubuntu with Geekworm x1003 - The Geekworm wiki is out of date FYI. This drive works great with Raspberry pi 5 and the x1003. I even have it running in forced PCIe Gen3 mode. I see a solid 800 Mbytes/s performance which is about what I would expect for gen3 at 1 lane. - the trick to get this working is you need to update your eeprom on the RPI5. Ubuntu does not update apparently so the only way to flash the eeprom to the latest is to cut a sd card with the raspberry pi os. run rpi-eeprom-update -a and then reboot. you can then connect the drive and everything works great. I had ubuntu on a sd car which I plugged into USB port on the pi and used the raspberry pi os "clone" feature to copy the os over to the NVMe drive. Then you just need to change the boot priority to NVMe and you're good to go
Review: killer combo! - here is the killer combo for the case, nvme hat and ssd for the raspberry pi 5. easy to connect in a few minutes. i removed the micro sd card to make sure only the ssd was being used. then i connected it to ethernet and booted up the pi. just hold down shift when you see the boot menu and it will download and install from the internet your OS distribution on the ssd. i am seeing speeds about 10x faster now. very happy with this combo. https://www.desertcart.com/dp/B0CMZ84GM8?ref=ppx_yo2ov_dt_b_fed_asin_title https://www.desertcart.com/dp/B08K79T9G5?ref=ppx_yo2ov_dt_b_fed_asin_title https://www.desertcart.com/dp/B0CSFHTJP8?ref=ppx_yo2ov_dt_b_fed_asin_title

## Questions & Answers

**Q: Steam deck compatible?**
A: NO. For Steam Deck, you need SSD M.2 2230 such as B09V4PBQRF (1TB capacity) and B09YYGJV7B (1TB capacity).

**Q: i have a 2011 hp usdt with a mini pci express x 1 slot available. is this the correct  ssd to use? the  mini sata slot has a 2042 m-sata drive.**
A: No, this will not work in your HP laptop. mSATA is different from M.2 NVMe PCIe.

**Q: Will this work with lenovo x250 in the wlan card slot or is there  any way i can use msata ssd in the same slot?**
A: No. You need M.2 SATA (Not NVMe PCIe).

**Q: Es compatible con hp elitebook 840 g2?**
A: Si es compatible

### ⭐⭐⭐⭐⭐ Perfect drive for my OrangePi 5
*by L***N on December 6, 2023*

I bought this drive to go in my OrangePi 5 to install the OS on instead of using a Micro SD Card. It fit as expected and runs the OS much faster than the traditional Micros SD card. I had not problems removing it from the unit and putting it in an external NVME case to transfer data. It doesn't run hot and it reads at a decent speed for PCI 3.0 storage. Price seemed reasonable at the time, no idea how much it costs when you read this, so shop around.
