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: Good Seller. Good Product. - Worked as intended. Using it right now. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08K79T9G5 | | Additional Features | Portable | | Best Sellers Rank | #158 in Internal Solid State Drives | | Brand | Samsung | | Cache Memory Installed Size | 256 | | Color | Black | | Compatible Devices | Desktop | | Connectivity Technology | PCIe | | Customer Reviews | 4.6 out of 5 stars 660 Reviews | | Digital Storage Capacity | 256 GB | | Enclosure Material | Nand Flash | | Form Factor | M.2 | | Hard Disk Description | Solid State Drive | | Hard Disk Form Factor | 2242 Millimeters | | Hard Disk Interface | NVMe | | Hard-Drive Size | 256 GB | | Hardware Connectivity | PCIE x 1 | | Installation Type | Internal Hard Drive | | Item Dimensions L x W x Thickness | 1.7"L x 0.9"W x 0.1"Th | | Item Weight | 0.01 Grams | | Manufacturer | Samsung | | Media Speed | 1300 MB/s | | Mfr Part Number | MZALQ256HAJD MZ-ALQ2560 | | Model Name | PM991 | | Model Number | PM991 | | Number of Items | 1 | | Special Feature | Portable | | UPC | 887276049069 | ## Product Details - **Brand:** Samsung - **Color:** Black - **Compatible Devices:** Desktop - **Connectivity Technology:** PCIe - **Digital Storage Capacity:** 256 GB - **Hard Disk Description:** Solid State Drive - **Hard Disk Form Factor:** 2242 Millimeters - **Hard Disk Interface:** NVMe - **Installation Type:** Internal Hard Drive - **Special Feature:** Portable ## Images ![SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Image 1](https://m.media-amazon.com/images/I/51RVXfnHjLL.jpg) ![SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Image 2](https://m.media-amazon.com/images/I/61Ix5sEw65L.jpg) ![SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Image 3](https://m.media-amazon.com/images/I/61XEHcLYH6L.jpg) ![SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Image 4](https://m.media-amazon.com/images/I/71-FiAV8KyL.jpg) ![SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Image 5](https://m.media-amazon.com/images/I/71U5YXoyfbL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works with RPI5 and Ubuntu with Geekworm x1003 *by T***M on April 13, 2024* The Geekworm wiki is out of date FYI.

Using it right now. ### ⭐⭐⭐⭐⭐ 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. ## Frequently Bought Together - Samsung SSD 256GB PM991 M.2 2242 42mm PCIe 3.0 x4 NVMe MZALQ256HAJD MZ-ALQ2560 Solid State Drive - Waveshare PCIe to M.2 Adapter for Raspberry Pi 5, Supports NVMe Protocol M.2 Solid State Drive, High-Speed Reading/Writing, HAT + Standard - Geekworm X1001 PCIe to M.2 HAT Key-M NVMe SSD PIP PCIe Peripheral Board for Raspberry Pi 5 Support M.2 2230/2242/2260/2280 SSD --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/304968281-ssd-256gb-pm991-m-2-2242-42mm-pcie-3-0](https://www.desertcart.hr/products/304968281-ssd-256gb-pm991-m-2-2242-42mm-pcie-3-0) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
