SSD benchmark

Is there a tool to test out the speed of the SSD?

If this is about the change is SSDs, there will be no noticeable difference in any real life scenario.

Nope not about the 2x lanes

Kdiskmark

I tried installing kdiskmark but it didn’t work and I’m completely dumb to Linux

The scenario where you put it into another device is pretty noticeable.

No it isn't. There's already two other threads where I've looked up the models from suppliers who've published specifications (Kingston and Transcend) and the 256GB Kingston is 1700MB/s seq read and the 256GB Transcend is 1700MB/s seq read (both are in synthetic tests, real world workloads will certainly be lower). PCIe Gen3 x2 has an available bandwidth of 2GB/s so neither SSD "needs" the PCIe Gen3 x4 link width.

EDIT:

Here is a quote from one of those threads since you probably won't be bothered to go actually look at them.

There have been two 256GB PCIe Gen3 x4 SSDs shipping in the Steam Deck: Kingston OM3PDP3256B-A01 and a custom Phison model ESMP256GKB4C3-E13TS.

There doesn't appear to be publicly available specifications for the Phison model, however, the Kingston model has the following specifications.

Model: OM3PDP3256B-A01
Form factor: M.2 2230
Capacity: 256 GB
Memory cell type: 3D NAND TLC
Data transfer interface: PCIe NVMe
PCIe version: Gen3 x4
NVMe version: 1.3
Read speed (ATTO, up to): 1700 MB/s
Write speed (ATTO, up to): 1100 MB/s
MTBF: 1 million hours

The "new" PCIe Gen3 x2 SSD that is now also shipping in the Steam Deck is a custom Valve firmware version of a Transcend MTE352T,

Model: TS256GMTE352T-VLV
Form factor: M.2 2230
Capacity: 256 GB
Memory cell type: 3D NAND flash w/ SLC caching
Data transfer interface: PCIe NVMe
PCIe version: PCIe Gen3 x2
NVMe version: 1.3
Read speed (CrystalDiskMark, up to): 1700 MB/s
Write speed (CrystalDiskMark, up to): 1000 MB/s
MTBF: 3 million hours

You must not understand the difference between an SSD and an SSD controller, nor what the words up to mean.

The PS5013-E13T is an SSD controller, and it is capable of 2500MB/s seq read and 2100MB/s seq writes. But that doesn't mean an SSD using that controller will magically have those speeds.

Yes you are right.

Standard E13T has R 1730 / w 1180MB/s , nothing crazy for a 3x2. We have the custom 3x4.

Glad you can read the brochure.

Again, neither of those links are for an SSD. They are for the PS5013-E13T PCIe Gen3 x4 interface with 4 NAND channel SSD controller. The ESMP256GKB4C3-E13TS SSD which uses a version of that controller is a custom SSD model from Phison for Valve as they don't even list M.2 2230 as a supported form factor for the PS5013-E13T.

The 512GB versions of the Phison and Kingston will show up to ~2400MB/s seq read in synthetic benchmarks like CrystalDiskMark, ATTO, etc. but they aren't going to actually see that speed in real world workloads, and certainly aren't going to sustain that speed in real world workloads.

Btw, google OM3PDP3256B-A01
Exact page layout and set-up, writing, numbers etc. as what you copy/paste-spam : https://exe.ua/en/product/p375947/

Look here it's a bit more serious :
https://www.digikey.com/en/products/detail/kingston/OM3PDP3256B-A01/15822181

Read 2400.

2400 > 1700

3x4 performs better than 3x2, no?

yes

The deck does cap both of these drives with its limitations and you can see it in benchmarks but believing marketing specs on SSD's is hilarious. Both of the 256GB and 512GB drives are only benched by decks that can't prove anything. I'll be getting my deck soon and I'm willing to bench it's 512GB SSD in my PC if someone with the other drive is willing to do the same we can get some real numbers on both drives.

So you're suggesting that the marketing of the SSDs is some how lower than what the SSD will actually perform like? You have an odd view on how companies market things.
