Hi,

SSDs are made for read and write access. Treating SSDs with kid gloves
is grotesque. Yes, using SSDs does wear out SSDs. However, using HDDs
does wear out HDDs and using door locks, does wear out door locks.

The internal drives of my PC are SSDs only. The oldest drive is > 3
years old. This might not be very old, but it's a small sized drive and
it still works. Small sized drives wear out faster, than drives with a
large storage capacity. I'm using five elCheapo Toshiba OCZ Solid State
Drives insider of my PC and never experienced an issue.

My heavy used iPad 2 is already 8 years old. Around a year I replaced
it by an iPad Pro for "heavy" audio productions. However, it still works
without failure. What ever the thingy in the iPad 2 is named, "SSD" or
not, it suffers from the same write cycle "issue", which actually is no
issue at all.

In my experiences modern heavy used HDDs at best do last for around 7
years, if parking and releasing heads to often is avoided. Regularly but
seldom used backup HDDs probably last way longer, let alone old MiB
sized HDDs. While some modern drives do last for 7 or more years, a lot
of HDDs fail sooner. It's not that seldom, that a HDD already fails
after 2 years, even when the heads very seldom were parked and released.

I don't see any reason for treating a SSD different than a HDD, at
least not when using it on a daily basis. I don't know if SSDs are
reliable when regularly, but seldom used as a backup drive.

Regards,
Ralf
