lspci output: It looks like it's a Samsung NVMe controller, and here are more details: |

Benchmarking... here's a listing on harddrivebenchmark.com for the Samsung. And on the Pi 5, running my disk-benchmark.sh:

Hey Jeff, I was just curious if this supported 4K Native Advanced Format. You can check using either For example my WD Black (which does) has this: |

hi @Steve-Tech, Have some RPI SSD's myself and it does not like it support 4k blocks as shown below: |

Hi @leander091, alright, thanks for checking! |

Here is a newly purchased Raspberry Pi 512Gb SSD. It no longer claims to be a Samsung, but is rather is a Biwin SSD. It was purchased from a big brand well known very respectable supplier, and if it is a fake, it's an extremely good one. The packaging and label all look perfect. I wouldn't personally associate Biwin SSDs nor its "KingSpec" controller with quality like I would with Samsung, but if this is genuine I assume the RaspPi Foundation know what they're doing. I'll tell you this: power consumption is remarkably low with this SSD. Like, crazy low. PCIe 2.0: Write load is 0.5 watts. Wow. Read load is 0.7 watts. PCIe 2.0 throughput performance is very competitive. PCIe 3.0: Write load is 0.9 watts. Read load is 0.8 watts. PCIe 3.0 throughput performance is nothing to be sniffed at. DRAMful SSDs have a bit faster reads. Other details: The claimed power use states do seem to very much correlate with empirically measured power consumption.

That is a bit less than the Samsung based SSD. In case it was a fake and I've been diddlied, I tried filling the drive to full: No i/o errors. Looks true sized. Obviously it ran out of SLC cache, that made it slow down to about one quarter peak write speed. I noticed that power consumption went up to 2.7 watts too, so running out of SLC cache does increase write power consumption considerably. That also agrees that the entire drive was filled. I see from searching the web that the Biwin-made drives appear to have become the default OEM for official RaspPi SSDs from Nov-Dec last year onwards. Multiple people report the same. I guess it's legit so. |

Raspberry Pi is now selling the Raspberry Pi SSD, a 2230-size NVMe SSD rated at PCIe Gen 3 speed.
I have a 256 GB model to test, and they are also releasing a 512 GB model. The product data sheet doesn't list certain specs like MTBF, TBW, shock ratings, or how many lanes of PCIe Gen 3 are supported (assuming you put it on a device other than a Pi 5).
I would like very much to find those things out, so once I get it hooked up, I'll post the full
