Different SSD versions on the market available from Samsung.

[SPDIF]

I will start with an good known one; The 970EVO Plus.

For informational purposes and against misunderstanding, the 970EVO plus had 2 versions available; For the original version of the Samsung 970 EVO Plus SSD, which uses the Phoenix controller, the latest firmware is 2B2QEXM7, the new version of the 970EVO plus uses the Elpis controller, same as the Samsung 980PRO and has firmware 4B2QEXM7.
The new 970EVO plus version has a larger SLC cache, an increase from 42GB in the original to 115GB in the new revision.


The 870EVO has three versions available, they all use different NAND packages.

An variant with SVT01B6Q ( Some of them can be upgraded to SVT02B6Q)
An variant with SVT02B6Q (Not up-gradable to SVT03B6Q) - This firmware update fixed some compatibility issues with certain motherboards and improved the performance and stability of the SSD
An variant with SVT03B6Q ( Latest 870EVO with new NAND packages)

Feel free to correct me or add other Samsung SSD's here, this is only meant to help users looking for the needle in the haystack, of all versions that are available, and can make them confuse with firmware versions also.

To my knowledge they are all using Samsung V-NAND V6 TLC 512Gb an 1Tb dies. So I don't think there are different dies. Sure the packages might not be the same but the dies themselves might not have changes

I got this little official info from Samsung after waiting month's;

SVT03B6Q is only offered to some variants of the 870 EVO SSD that use new NAND packages.

Sure.... but since it's Samsung stills smells like BS to me......
Like I mentioned i'm over 90% sure they didn't change the dies.
The worst case scenario would be if they changed the Package count and Die count per package. Like instead of have a 1TB drive with 4 nand packages, having a single package with 16 dies stacked.
But again.... still think it's BS

Thanks GabrielLP14 for your help! With this can help user's understanding all versions on the market.

Then i find it strange that you can't update from SVT02B6Q to SVT03B6Q, but yeah Sammy's secret sauce i think.

Now i suddenly see new 870EVO's in my shop from 1, 2 TB versions with SVT03B6Q as firmware.
Sometimes i get 870EVO from 4TB with firmware SVT02B6Q, but can't be upgraded to SVT03B6Q.

No response from Samsung on that one.

For about the 970PRO, this version use 1B2QEXP7 as firmware and is the only one that still uses REAL 2bit MLC. Uses Samsung Phoenix Controller, same as the 970EVO Plus old version.
The 890 and 990PRO are using 3bit MLC (TLC).

What is the difference between the 970EVO and the 970EVO Plus?

Samsung 970 EVO using Samsung’s own 64-layer TLC V-NAND Whereas, the Samsung 970 EVO Plus uses Samsung’s 92-layer TLC V-NAND.
Both these SSDs are using the same Samsung Phoenix Controller.
the 970 EVO Plus has around 8 – 10% higher speeds as compared to the same version of 970 EVO. The 970EVO has 2B2QEXE7 as latest firmware

Appreciate your input and opinion. However, without sourcing your "knowledge", it's just your opinion, and you're dangerously close to thread-crapping. Next post from you in here should either be one containing reliably-sourced basis for your opinion, or you'll be assigned points and thread-banned.

Yes the 970 EVO and EVO Plus uses the same Controller, also, the 970 EVO Plus recently had that upgrade with the 980 Pro Controller and NAND Flash
