Standard Use drives have 20,000-40,000 hrs on their SMART power-on counter, the drive’s own record of how long it has run. We read that number from the drive, print it on the certificate in the box and show it on each unit’s public test report. Every tier passes the same tests: SMART health, an extended self-test, zero bad sectors and a benchmark in range for the model. The tier changes the price and the warranty, not the pass bar. The full criteria are on how we test, and usage tiers explained compares all five.

Standard Use tier: common questions
What does Standard Use mean?+
Standard Use is the usage tier for certified drives with 20,000-40,000 hrs on the drive’s own SMART power-on counter. Typical datacenter service. Best price per TB. The hours are read from the drive and never reset or hidden.
Do Standard Use drives pass the same tests as other tiers?+
Yes. Every tier clears the same bar: SMART health PASSED, a clean extended self-test, zero reallocated, pending and uncorrectable sectors, and benchmark throughput in range for the model. A drive that misses it is not sold in any certified tier.
What warranty comes with Standard Use drives?+
Each tier carries its own warranty term, shown on the tier card on the product page. Certified tiers carry up to 2 years.
