Reliability Specifications

The Oracle 1.6 TB NVMe SSD reliability specifications are shown in the following table:

Uncorrectable Bit Error Rate (UBER)
Uncorrectable bit error rate will not exceed one sector in the specified number of bits read.
In the unlikely event of a non-recoverable read error, the storage drive will report it as a read failure to the host; the sector in error is considered corrupt and is not returned to the host.
< 1 sector per 1017 bits read
Mean Time Between Failures (MTBF)
2 million hours
Mean Time Between Failures is estimated based on Telcordia methodology and demonstrated through Reliability Demonstration Test (RDT).
Data Retention
The time period for retaining data in the NAND at maximum rated endurance. 3 months power-off retention once storage drive reaches rated write endurance at 40° C.
Endurance Rating
  • Up to 14 PBW (petabytes written)

    Endurance rating verification is defined to establish UBER <1E-16 at 60% upper confidence limit.

  • 5 Drive Writes/day (JESD219 workload)

    The number of drive writes such that the storage drive meets the requirements according to the JESD219 standard.

Temperature Sensor
Internal temperature sensor with an accuracy of +/-2° C over a range of -10° C to +85° C which can be monitored using NVMe Health Log.
The sensor has an accuracy of +/- 3° C over a range of -20° C to 125° C. SMBUS temperature sensor is not reported in NVMe Health Log.
Drive provides out-of-band access to temperature by means of SMBUS.
Out of Band Management (SMBUS)
Provides out-of-band management by means of SMBUS interface. This requires 3.3V auxiliary voltage.
SMBUS access includes the VPD page and temperature sensor.
Hot Plug Support
Supports PCIe presence detect and link-up detect.
Device advanced power loss protection provides robust data integrity. During IOs, the SSD's integrated monitoring enables the integrity of already committed data on the media and commits acknowledged writes to the media.
