Re: Slowly, then all at once.

A second KingSpec 128GB 1.8″ 40-pin ZIF Solid State Disk only survived four weeks’ very occasional use before it, too, expired. On one otherwise unremarkable evening, I placed the XT on a sideboard and shut the lid, putting it to sleep.

A short while later, on hearing the fan running at full speed, I opened the lid only to be greeting by an unfriendly MS DOS-style error message. “System Error”, “Error reading from disk” or somesuch. Whatever it was, the computer refused to boot at the next time of asking. I was, later, able to use Windows 7’s System Recovery Options to recover some files from the stricken SSD.

Much to their credit, the drive’s vendor agreed to RMA it (again) and replace it with a RunCore Pro IV 1.8″ 5mm PATA Zif Solid State Drive SSD. Three weeks later, and it’s.. well, still working.

Slowly, then all at once.

The blurb for the KingSpec 128GB 1.8″ 40-pin ZIF Solid State Disk (MLC) claimed a “write endurance” of 10 gigabytes per day for 80 years, and an “unlimited” “read endurance.” After very nearly 10 months’ reading and writing considerably less than that, mine went wallop.

It happened much as per Hemingway‘s description of how people go bankrupt: the first sign of trouble was Windows Explorer hanging while copying (reading, not writing) a file. This failed with a Device I/O error, then chkdsk reported “10 bad clusters”, and then the host PC refused to boot at the next time of asking.

Happily, the drive’s vendor agreed to RMA the drive and exchanged it for what looks like a later revision of the same model. Once installed, Windows 7 reported the following:

Which is to say, not quite the same but also not very different.


UPDATE: This second KingSpec SSD lasted just four weeks before it, too, expired.
