Hello to all,

can you tell me about 1tb nvme units (budget € 150) that do not slow down?
that the speed is stable even after several read and write cycles.
I know that among the best there are the Samsung 970 PRO...but they would be out of budget.
Thank you.

No, TLC NAND slows down after the SLC buffer is full.

SLC > MLC > TLC > QLC.

All NVMe v1.3 M.2 blades are compatible with MP5,1, people are using EX950 without problems.
Thanks for the clarification.
On the € 150 of MLC nothing is found then?

Slightly off topic.

My recently purchased & firmware updated Samsung 500gb 970 EVO Plus doesn't seem to slow down at
all.

US$109 + shipping https://www.amazon.com/Samsung-970-EVO-Plus-MZ-V7S500B/dp/B07M7Q21N7

Just did four Blackmagic runs.

Pretty well the same in all 4 uninterrupted runs. Not 1TB but good value for what it delivers.

( WARNING : Check the Firmware revision in "About this Mac / NVMe/ " before formatting in Mac OS. the latest firmware is 2B2QEXM7 )

With the serious Samsung Evo (also plus), they would always be slowdown,right?
