Overall summary of a year’s testing external hard disks and SSDs ranging in cost from $50 to more than $200 per TB. Which is best?

A simple worked example showing the effect of snapshots and changes in hidden system files in consuming free space on APFS.
Archiving is very different from backing up, from the storage media used to integrity checks. Here are pointers to help you preserve important documents.
How to design a method which not only detects errors in file data, but enables them to be corrected? A tale of Hamming, Reed, Solomon and CDs.
Two reasons for paying more and using SSDs are that they’re faster and more reliable. Data on failure and reliability don’t appear as clear as the ads, though.
Storage has to be reliable, efficient and resilient. However, efficiency and resilience oppose one another. What’s the best solution? New file formats, CRC in the file system, or what?
It depends whether you’re going to boot macOS from it, on the space required for snapshots, and how large they could become. And there’s more.
Thunderbolt 5 isn’t available yet, and in any case will probably offer no more than 6 GB/s. So what is the way ahead for Apple in its successors to its M1 series chips?
Armed with just a couple of flashy Thunderbolt NVMe SSDs and his home-made benchmarking app, we discover whether Thunderbolt is any better than USB 3.x.
M1 Macs don’t support SMART monitoring over USB-C, forcing us to choose between Full Security without SMART, or Reduced Security with SMART support.
