In terms of endurance, TechReport reveals that that the majority of consumer quality SSDs tends to be able to endure more than 700TB of reading & writing, with a few others surviving up to an exceptional 2.5 pentabytes. They also found that TLC type SSDs had generally less endurance than their MLC counterparts.
Compare that to Backblaze’s tests with their HDDs. Backblaze has kept up to 25,000 hard drives constantly online for the last four years. Every time a drive of theirs failed, they noted it down, and then slotted in a replacement. After four years, Backblaze has collected detailed data of the failure rates of Hard Disk Drives over the first four years of their life.
It seems that hard drives have three distinct failure “phases.” In the first phase, which lasts 1.5 years, hard drives have an annual failure rate of 5.1%. For the next 1.5 years, the annual failure rate drops to 1.4%.
After three years, the failure rate explodes to 11.8% per year. In short, this means that around 92% of drives survive the first 18 months, and almost all of those (90%) then go on to reach three years.
Extrapolating from these figures, just under 80% of all hard drives will survive to their fourth anniversary. Backblaze doesn’t have figures beyond that, but its distinguished engineer, Brian Beach, speculates that the failure rate will probably stick to around 12% per year.
Also, I had to retire my personal RAID 0 game drive array over the same thing.. It worked but was showing it's age.. lol
