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

Arrived on time and was as advertised. A good deal for the price, and perfect for my project.

As soon as in installed it on my gaming computer installed windows 11 and all the lag and freezes went away. Thanks

The Samsung NVMe SSD works well compared to my old, slow SATA SSD. Haven't found any problems with it

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. Update to 5 star... I've purchased several more. Most are coming initialized now, just unformatted. I got 1 bad one (It happens). Sent a new one out same day and I was able to print out the return label - no charge. Very good seller.

Great value Good size for running OS. Fast transfer rate

The stickers on the drive are questionable, and mine didn't even say "samsung" anywhere. As many others have noticed, samsung magician does not recognize it as original. Anyways, it did work at first, as any other good ssd. I cannot say if it was faster or not than other drives I use (I have other REAL samsung ones) because I mainly used it for a custom project on a raspi pi 5. While I was coding the project, it required me to flash the drive, test, find bugs, fix them, reflash and so on. It was working alright but then, I reflashed it and it got stuck on the initial raspi pi os update. I thought it was just an os bug, so I turned it off and on. It started ok and got stuck on the same spot. Perhaps a bad flash I thought, so I took the drive and reflashed again. Tested and got stuck at the very same stage. thought it could be, even if unlikely, a faulty raspi pi board. So I switched the drive with a real samsung one freshly flashed and it worked correctly. I tried using it as an external drive for windows os too but nope, nothing; it does appear in the device manager but it fails, like if I connected and disconnected it several times. TLDR: works for a few months, then fails and becomes trash.

This NVMe storage device arrived quickly and installed seamlessly - after cloning my OS to the new SSD I can already notice my system running faster! Great product 😊

Works well. Went back and purchased another one for backup.

Great little drive. I've installed it in a raspberry pi 5 and as it only reserves 1 pcie lane to access it any benchmark would be unfair. Subjectively it is much faster than the sd card it replaced and copying the OS from the card to the drive was performed by the Pi OS drive copy tool which recognised the drive and copied everything over. Very happy.

Tut was er soll.

しっかり早い

prodotto praticamente quasi nuovo, il disco ha lavorato per una decina di ore, è arrivato in una scatola quasi troppo grande per l'oggetto di dimensioni così piccole anche se era veramente ben imballato. Installato e funzionante, unico disguido tecnico che non ero a conoscenza essendo un ssd OEM non è possibile usare il software samsung migration data.

TERRAMASTERのNAS F2-223 のキャッシュ用に使えないかと安いM.2 SSDを物色していたら、このSSDを見つけて即購入。 適合SSDはTERRAMASTER純正品のみで、ネット上の少ない情報では相性で動かないものばかりでしたが、しっかり認識してます。再起動とかを繰り返さないと認識してくれませんでしたが、それはもうひとつの手持ちのSSDと同じだったので、特に問題はなかったです。GEN4も上位互換なら問題ないだろうと。 もっとも、自分の使い方ではキャッシュのありがたみは感じないため、自己満足以外の何物でもないですが、ただ、TOS6ではシステムをSSDにも入れられるようになっているので、起動は若干早くなったような・・・。
