The SSD Endurance Experiment

I was doing some research on SSD drives and I found this cool post over at tech report called “The SSD Endurance Experiment: They’re all dead”

Samsung 840 Pro

They write an endless stream of data to test the limited write tolerance of the flash memory and wait to see how long it takes them to fail. All of them lasted longer than expected but the Samsung 840 pro lasted the longest. The Intel drive did the worst. This was due to its design to kill itself ones it thinks its write tolerance had been exceeded.

They also go into some neat low-level stuff. Talking about how the SSD drives work and why writing to the drives degrades them over time.

SSD Endurance results summed up.

  1. Samsung’s 840 Pro 256GB – 2.4PB wrote
  2. Kingston’s HyperX 3K 240GB – 2.1PB wrote (compressible data)
  3. Corsair’s Neutron GTX 240GB – 1.2PB wrote
  4. Samsung’s 840 Series 250GB – 900TB wrote
  5. Kingston’s HyperX 3K 240GB – 728TB wrote (incompressible data)
  6. Intel’s 335 Series 240GB – 700TB wrote (designed to kill itself)

The post is a few years old so lots of new drives out. I got the Samsung 850 EVO and I love it so far. But I am no were close to writing 2.4PBs haha.

Get more detail on the experiment at tech report. It was a very interesting read!
