M1 Mac SSD Wear Issue Tested and Explored [video]

Large scale chia plotter here. I've used over 20 different brands of SSDs; you could say I "stress-test" NVMes for a living.

The "TBW warrantied" claims are not so meaningful. On every single NVMe, I have gotten at least 2-4x the rated TBW warrantied without encountering ANY issues, whatsoever.

The NVMe spec classifies the rating as being able to retain data, powered off, for 1 year. If your macbook is connected to power more than once in a year, you wouldn't expect to lose data. So real ratings are higher than claimed in the video.

I'd expect the Mac's NVMes to work for 4-8 years of heavy usage, before failure.

Which SSD would you say is your favorite?

The short answer is: every NVMe is different, some may be better at burst speeds, some may be better at sustained writes, some for endurance, and of course there's the question of value.

If you make me pick:

• I have nearly zero money to spend: MX500 2.5" or BX500.

• Value: Kingston A2000

• Balanced: WD SN750

• Endurance / professional scratch disk use: Samsung 970 Pro (NOT 980 Pro! Tlc instead of MLC), or Gigabyte Aorus, or Corsair MP600

These are consumer NVMes for desktop pc/workstation usage. If you're building servers, you probably want to consider server-grade hardware.

Thanks a lot! I’m planning on upgrading from my 2010 PC to the new Ryzen APU and am looking for some good storage. I appreciate your thoughtful response!

Chia plotting seems to very different workload compared to swap. TBW rating client workload is defined by JEDEC, I believe it's harder workload than Chia plotting (larger block size).
