It seems Silicon Power is grossly conservative with the endurance rating. Similar drives have dramatically higher published endurance ratings. I would assume the same nand and same controller would have the same, or very similar, endurance. This is indeed the case with other E12/bics3 nand drives. The BPX Pro and MP510 are identical hardware with over-provisioning have ~1700TBW/960GB. Inland Premium (Microcenter house brand) is same hardware without any over-provisioning has a 1600TBW endurance for a 1TB drive.

Its hard to believe the Silicon Power P34A80 has less than a third of the endurance of other drives featuring the exact same hardware.

Where does the meager 125TBW/256GB endurance rating come from? It doesn't appear that Silicon Power published an endurance number on their website.

Sabrent Rocket is another budget E12/bics3 drive with a rating of 1665 TBW/1TB.
TEAM GROUP MP34 is also rated at 1665 TBW/1TB.

Five other drives with the E12/bics3 all have 1600+ TBW for a 1TB class drive.
Hard to believe that the Silicon Power only has 500TBW/1TB

I would guess that it has to do with limiting their liability. The endurance ratings come directly from the company after my inquiry.

It seems quite likely the Silicon Power endurance information is erroneous. How could one explain that of the six drives mentioned, all with Phison E12 controller and BICS3 NAND, five have 1600+TBW ratings and one has a 500TBW rating. Logic would suggest the 500TBW rating is simply wrong.

I contacted their tech support, they said the 2TB model has an endurance of 3115TB.

According to the review, this disk should ensure AES encryption. How to start using it/set password? Is that executed through disk password in BIOS? Have anyone succeded in setting this? If yes in what laptop?

Ok, I've received the answer from Silicon Technology and... they are saying that this disk is NOT supporting any encryption. As I was furious and very confused I've asked them once again and they answered the same saying that they confirmed this twice with engineers. So forget about hardware encryption guys.....

The Silicon Power P34A80 comes with all the performance you could ask for from a high-end TLC based SSD at a similar cost to those QLC based SSDs like the Intel SSD 660p and Crucial P1. What’s not to love?

I have this and I am returning it for incompatibility reasons.
it's like this , every ssd Nvme Pcie I have reports as 512 sector the brands are Crucial and Samsung yet this reports as 4096 regardless of the enclosure you put it in as I also found out that all enclosures use the same chipset .It means you can't clone to this drive because it does not use 512e it's 4kn and that is the way it stays .
I'm going back to Samsung at least I know I can clone to their drives because of the chipset they use which is different from the Silicon power chipset.
It's something you should be aware of as I have dragged the internet looking for some meaningful advice but in the end nobody knows , so just be aware you can't change the sector size and it will always report as 4096 because of the controller.

Interestingly, there are tools out there to change that tho. Have you emailed them? I know Sabrent has one for their E12-based SSDs. You can also use your motherboard's built-in secure erase tool to switch between 512e and 4K sectors if it has one. What software are you using? Ideally, it should be able to clone over the data regardless of source and destination sector sizes, it seems tho that the software is lagging support for the hardware here.
