It is common to see MTBF ratings between 300,000 to 1,200,000 hours for hard disk drive mechanisms, which might lead one to conclude that the specification promises between 30 and 120 years of continuous operation.

Mean Time Before Failure (MTBF) In most hard drive specification sheets, the calculated reliability is quoted as MTBF hours. Typical values are in the range of 500,000 to 1,500,000 hours. For instance for the HGST HMS5C4040BLE640 the MTBF specification is 800K hours = 92.6 years. Unsurprisingly, this does not imply that the hard drive you are buying will …

Nowadays, this number is around a million hours for an “enterprise” hard drive. Some drives are rated at 1.5 million hours. Now, thats a good stretch to time.

For example, a typical hard disk MTBF’s numbers range between 300,000 and 1,000,000 hours. This is quite a high number, equivalent to 34 to 114 years. These numbers are way too high, and practical experience shows that the posted lifetime of a drive is more likely one tenth of it, typically 3~5 years.

The mean time to failure (MTTF) of those drives, as specified in their datasheets,ranges from 1,000,000 to 1,500,000 hours, suggesting a nominal annual failure rate of at most0.88%. We find that in the field, annual disk replacement rates typically exceed 1%, with 2-4%common and up to 13% observed on some systems.

With consumer hard drives, it’s not uncommon to see MTBFs of around 300,000 hours. That’s 12,500 days, or a little over 34 years. Meanwhile, enterprise-grade HDDs advertise MTBFs of up to 1.5 million hours, which is the best part of 175 years. Could you imagine if these MTBFs were real-world expectations of hard drive longevity and reliability?

Take the MTBF rates though, some manufacturers are claiming 1.5 million hours of use. This equates to 171 years of constant use which seems ludicrous. To calculate MTBF this formula is used: [short time period] * [number of drives tested] / [number of drives tested which failed in that period] = MTBF.

The 2.5-inch hard disk drives with a Serial Attached SCSI (SAS) interface offer 10,000 to 15,000 rotations per minute , 500 input / output operations per second ( IOPS ) and up to 2.5TB of storage capacity. Manufacturers specify an MTTF of up to two million hours. The hard drives are designed for a workload of 550TB per year.

Hard Disk Drives (HDDs) vs Solid-State Drives (SSDs) The two most popular types of hard drives have different life expectancies. My colleague wrote an informative blog post detailing the difference between HDDs and SSDs recently that can provide you with extensive information. But here, I’ll touch on how long each type will last.
