Some advanced users have been reporting an overuse of the SSD for writing and reading data on the newly released Macs with M1, Apple’s first computer chip based on ARM architecture. The issue could eventually affect the lifespan of the internal SSD used in M1 Macs — not to mention the machine itself.
ChipGenius 4.19.1225 on 32-bit and 64-bit PCs. This download is licensed as freeware for the Windows (32-bit and 64-bit) operating system on a laptop or desktop PC from hardware diagnostic software without restrictions. ChipGenius 4.19.1225 is available to all software users as a free download for Windows. We have tested ChipGenius 4.19.1225. The first 3 bits appear to be the chip address, I guess the next is a read/write select. I used a AVR mega323 to detect the start of the serial transmission look for the address of chip1+read (black apparently) then pull data low for 6 clock edges. I'm sure I can reset 3 of the chips by tapping into chip1 signal. 1.3 Similarity in writing method One of the similarities between external EEPROM and emulated EEPROM with the STM32F40x/STM32F41x embedded Flash is the writing method. Standalone external EEPROM: once started by the CPU, the writing of a word cannot be interrupted by a CPU reset. Only a supply failure will interrupt the write process, so Read. The life of a flash drive is approximately equal to the chip-level endurance (# of writes) + the intelligence of the FTL. The tests The team investigated 3 USB drives: a generic 64 MB; a house. Read/write life cycles are considerably shorter at 3,000 to 5,000 cycles per cell. Pros: Cheapest to manufacture which in turn leads to cheaper to market SSDs. Cons: Cells will survive considerably less read/write cycles compared to MLC NAND. This means that TLC flash is good for consumer use only. Recommended for.
As noted by users on Twitter and also on the Linus Tech Tips forums, macOS indicates that the internal SSD of M1 Macs has registered “extremely high drive writes over relatively short time.” One user points out that in some extreme cases the SSD has already had consumed about 13% of the maximum warrantable total bytes written (TBW).
Some more professional users of the new M1 Macbooks are experiencing extremely high drive writes over relatively short time. The most severe cases have “consumed” about 10-13% of the maximum warrantable TBW value of the SSDs (given their capacity & using values for equivalent market-available NVMe drives).
Since SSDs are based on chips rather than mechanical parts, they all have a predetermined lifespan based on how much they are used for writing and reading data. The more you write data to an SSD, the faster it will show bad behavior such as slowness or even data corruption. As the internal storage of M1 Macs are soldered to the logic board, users will have to replace the entire computer if affected by an SSD defect.
With a regular use, this can take up to 10 years to take effect, but today’s reports suggest that the lifespan of the M1 Mac internal SSD can be reduced to as little as two years due to macOS behavior. Another user says that a M1 MacBook Pro with 2TB storage and 16 GB RAM has already registered 3% total usage of the internal SSD after only two months.
Unfortunately, the reasons behind this problem are still unknown. This could be either the M1 chip constantly using the Mac’s internal storage for memory swap (which is basically using the SSD as virtual RAM) or just another bug found in macOS Big Sur.

Apple hasn’t yet commented on this issue, but hopefully the company will fix it with a future macOS update.

The basic input/output system (BIOS) on a computer is typically stored on a non-volatile microchip called a BIOS chip, which is placed on the motherboard of the computer. This chip is integral to the proper operation of the computer, and if it is corrupted or damaged, the computer will likely no longer be able to start up. There are several ways to try to repair or otherwise deal with a corrupted or damaged chip, though these can be quite complicated. The chip on a motherboard is usually placed by the manufacturer, and documentation with the board will often indicate what type of BIOS program is on the chip.
A BIOS chip uses non-volatile memory, which means that even when power is not supplied to the system, the data on the chip remains. This type of memory is also used for hard drives, but is not used for random access memory (RAM) and is integral to how the chip operates. When a computer first starts up, the chip runs the BIOS in order to properly initialize the computer startup process.
The BIOS allows the hardware inside the computer to properly communicate and work together during startup. This means that, when a computer is started, the BIOS allows information to be displayed on the monitor, allows the computer to recognize the keyboard for input or changes to the BIOS settings, and properly communicates with the hard drive in the computer. Once this happens, the program hands control of all these systems over to the operating system (OS) on the hard drive and full start up of the computer occurs.
What Is Read Write
If the BIOS chip on a computer’s motherboard is damaged or corrupted, then this initial program cannot be run properly and the computer will not be able to start. There are two basic ways to deal with this type of situation: replace the BIOS program or replace the chip. To replace or repair the program involves a process called “flashing” the BIOS on the chip. This basically reinstalls the BIOS, which can be somewhat complex, and if a mistake occurs, it may render the chip useless.
Replacing the chip can be done by either switching it out with a new one or by replacing the motherboard. A new chip can usually be acquired from the motherboard manufacturer, but attaching the chip to the board does require some basic knowledge of computer engineering. It can often be easier to simply replace the motherboard within the computer, and this can be used as an opportunity to upgrade the hardware itself to a more powerful board.
