SD cards and SSDs are based on the same technologies, so why the stark differences in performance?

Recently, it was reported that after a year in space, half of the SSD drives on the HPE Spaceborne computer had been fried. This suggests that SSDs are not suitable for use in space.

In contrast, SD cards have been used successfully for years. They are commonly used by virtually all of the photography cameras on board the ISS, and have performed perfectly. They are also used by small satellites. Somehow, they do not seem to experience these issues. Why?

    $\begingroup$ It might be a difference in the enclosures used, not the media. $\endgroup$ – JCRM Feb 4 '19 at 12:46
  • $\begingroup$ @JCRM ISS is a pretty massive enclosure compared to a small satellite. Could anybody point to any studies that prove the claims in the question? $\endgroup$ – asdfex Feb 4 '19 at 12:50

    $\begingroup$ This sounds hopelessly vendor-specific and exact-chipset-specific to me. SSDs are often using much higher-performance controllers than SD cards, I suspect. $\endgroup$ – ikrase Sep 21 '19 at 9:52
