Samsung 840 250GB Endurance Updates

Over the next few months or until the tragic end, we'll update this article with updates about the life and eventual death of the 840. Along the way we'll post milestones when possible, but at the very least update the article every month.

Update - 24 Hours

I felt it was important to publish an update at exactly 24 hours into the test to see how the drive was progressing.

At exactly 24 hours into the endurance test we've written 12.75 TB to the Samsung 840. The average speed was 154.85 MB/s.

Milestone - 100 TB Written

Our first milestone comes just 188.5 hours into the endurance test. Our 250GB 840 wrote just over 101 TB of data. The average write speed is at 156.35 MB/s. The drive seems to be writing data faster than during the 24 Hour update.

Milestone - 1024 Hours (March 11, 2013)

The drive is now up to 1024 hours and at that point the power went out in the lab due to a snow storm. While unplanned, the power outage worked out well for our test because we needed to power down the drive in order to test the transistor gates. As NAND flash wears the gate walls thin and the ability for the SSD to hold a charge diminishes. We can now program the host system to power down every 1,000 hours and keep power from the SSD for 72 hours. As of hour 1024, the Samsung 840 250GB SSD is perfectly fine.
