OEM Samsung PM9B1 256GB M.2 PCI-e GEN 4X4 NVME SSD Internal Solid State Drive 80mm 2280 Form Factor M Key

This used SSD come with low usage, it works like a new one. It may be bit slow due to it dram-less design, but it's ok for general use. Just keep in mind that it will use your own memory as cache, so it's not good for device that is low on memory

A year later no issues or errors! Samsung is one of the better oems

Might not work with some NVME to USB adapter's. It's OEM but still a Samsung - a trusted name for reliability. And it does have a volatile write cache according to CrystalDiskInfo. However it presented a problem I haven't encountered before (reason for only 4 star). I put it in a NVME to USB adapter (it supports other gen4x4's) and it didn't show up, so I went to manage, then storage (Win11) to assign a drive letter. The computer recognized it but said it wasn't initialized. When I tried to initialize it I got an error (for both GTP and MBR). Then I went to diskpart and cleaned it. Still unable to initialize and not even seen by 3rd party software. I didn't give up though, I've never had a Samsung fail and I like a challenge. So I reluctantly put it on the second NVME port (speed is only NVME 3 x 2) on my motherboard for 1 last try. It was recognized and I was able to initialize it. Oddly it was still GPT partitioned (it should have been erased from before when diskpart reported successfully cleaned) but unformatted. Set to NTSF easily. I didn't try to clean it again to change to MBR and put it back in the adapter, I've always been successful using GTP formats in it and I'll going to put it in another PC with a NVME PCIe adapter. I did speed test it and it was still better that a SSD, but really not a relevant speed test with the 2nd slot speed available. Must be something with the firmware it uses. Info does show it's used (probably had HP OS on it being OEM) with very low hours but smart info can be overwritten with the right software to do it - somewhat unlikely for the price they're charging. Overall a good value if the size is enough for your needs. Update EDIT- It did work in my NVME to USB adapter after it was initialized and formatted on the MB, for some reason it just couldn't be done from the adapter I use.

Solid M2 SSD, used it in my raspberry pi compute module 5 with the waveshare mini carrier board B. It overhangs on the board due to being to large for it, but it connects none the less. Have done a triple partition successfully of an extra storage, a full system recovery image partition and 64GB Eram partition. Ran through Armbian OS Trixie. Has solid read/write speeds and is worth the price. Should grab 2 just because its nice to have an extra M2 storage.

Labels on device were not was not what its was it had an amazing 8GB . Check it immediately after receiving it returning it next morning

Funciona perfecto

Works great!

Nothing particularly outstanding with this OEM drive, but I paid nearly $25 and it is exactly what I paid for. It works!I would probably keep critical files backed up elsewhere to be safe!
