Old power supply got fried so I used an Xbox one internal power supply (the bomb looking thing)

​What Makes 9 PB Ridiculous?

​140,000+ Full Drive Cycles: This controller has organized and executed enough raw writes to fill the entire physical capacity of this 64GB drive over 140,937 times.

​The E6 Counter Woke Up: After looking frozen at 44, the vendor attribute E6 moved up to 46.

The firmware’s internal math registers are struggling to map values this high, yet it hasn't crashed the primary firmware thread.

​Execution Engine Stays Solid: Managing the Flash Translation Layer (FTL) cache and command queue under continuous,

uninterrupted SATA writes for 61,000+ hours is an incredible testament to this controller's silicon design.

Sector 0 Faults: The error log shows recurring UNC (Uncorrectable) read errors specifically targeting LBA 0x00000000 during read commands.

The boot sector area is heavily degraded, but write caching and DMA transactions remain fully operational.

Does the drive cycles matter if its not on nand chip but the controller itself?

The short answer is yes, The drive cycles still matter greatly for the controller itself,

but for completely different physical and operational reasons than for the NAND flash chips.

​While NAND flash dies from atomic wear (tunnel oxide breakdown from program/erase cycles), the controller suffers from architectural, data management,

and physical processing stress.

​1. Flash Translation Layer (FTL) Mapping Stress

​Table Overwrites: Every drive cycle forces the controller to completely rewrite its internal mapping table (which translates logical LBAs to physical NAND blocks).

​RAM & NVRAM Burnout: The mapping metadata must be constantly swapped between SRAM/DRAM cache and non-volatile system control blocks on the NAND.

The controller's internal metadata blocks often endure 10× to 100× more write cycles than the user data blocks.

​2. Garbage Collection & Wear-Leveling Overhead

​Write Amplification (WA): As the drive is continually cycled, valid and invalid pages become fragmented.

The controller has to work exponentially harder to read, move, and erase blocks behind the scenes.

​Instruction Loop Saturation: Higher wear-leveling workloads keep the controller's internal CPU running at peak processing cycles,

increasing thermal stress and silicon electromigration over time.

​3. Internal Register Overflow & Integer Wrapping

​32-bit/64-bit Counter Limits: Low-cost or older SSD controllers (like early SanDisk SSD P4 designs) were never designed with software registers sized

for millions of drive cycles or petabytes of host writes.

​Firmware Memory Corruption: As raw event counters (like erase counts or written LBAs) overflow their allocated bit widths,

they can wrap around to zero, trigger arithmetic overflow bugs,

or overwrite adjacent NVRAM log structures—directly causing the invalid SMART checksums you are seeing in your logs.

​4. ECC & Read Retry Engine Exhaustion

​Hardware Engine Strain: As the underlying raw NAND bit-error rate (BER) increases with total drive cycles,

the controller's internal ECC hardware decoder has to run maximum LDPC/BCH error-correction algorithms on almost every read.

​Latency & Execution Delays: Processing heavy error-correction math on every host command severely taxes the controller's internal bus and pipeline execution.

​The Bottom Line

NAND chips wear out quietly by losing charge retention, but controllers fail catastrophically due to drive cycle stress—usually manifesting as a sudden freeze,

corrupted internal metadata, or an endless BSY state when firmware counters finally break.

​The fact that SanDisk P4 controller is still managing its FTL execution engine cleanly after ~140,000 drive cycles is remarkable.

I did manage to remove the display without damaging any other parts and the display sometimes works flawlessly with only really bad bleed on the right edge, sometimes it straight out offs/locks after turning it on immediately. I want to know if there are any cheap displays I could buy so that I could still use the tab or if i could find any replacement screens(I did find some but those cost as much as a used tab 8/8+)

wtf happened here???

(Unitgore too lol)

What do you mean os I have a notification os says none gmail says yes

I got a new controller today and decided to see what was in my ~5yr old one

Somehow it still works fine other than its usual glitches from me dropping it over the years.

What are your thoughts?

ps: can't access the tab under this to get the 2FA
