Raspberry Pi SSD

[geerlingguy]

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 lspci output here.

@bretmlw's review: Official Raspberry Pi NVMe SSD Review

[Steve-Tech]

Hey Jeff, I was just curious if this supported 4K Native Advanced Format.

You can check using either nvme id-ns -H /dev/nvme0n1 or smartctl -c /dev/nvme0n1, and it'll be down the bottom as LBA Format or Sizes.

For example my WD Black (which does) has this:

LBA Format  0 : Metadata Size: 0   bytes - Data Size: 512 bytes - Relative Performance: 0x2 Good
LBA Format  1 : Metadata Size: 0   bytes - Data Size: 4096 bytes - Relative Performance: 0x1 Better (in use)

[leander091]

hi @Steve-Tech,

Have some RPI SSD's myself and it does not like it support 4k blocks as shown below:
LBA Format 0 : Metadata Size: 0 bytes - Data Size: 512 bytes - Relative Performance: 0 Best (in use)

[Steve-Tech]

Hi @leander091, alright, thanks for checking!
