For our product, we are developing with DC S3700 series "INTEL SSDSC2BA400G3" SSDs and we are trying to understand the life span. From the SMART data we get conflicting numbers from the “Total LBAs Written (0xf1)” and “Media Wear out Indicator (0xE9).”
Could you help us understand how to determine SSD Life? And why the two SMART parameters tell a different story?
Intel Spec:
400 GB SSDs should have a life of 7.30 PBW
SMART Data:
"Total LBAs Written": 0xf1 : 100: 100: RAW: 0x00000cc41bab
This translates to 7.18 PB written = (214178731 count)*(65536 sectors/count)*(512 bytes/sector)/(1000^5).
Though, the media wear smart parameter shows 55
"Media Wearout Indicator": 0xe9 : 55: 55: RAW: 0x000000000000
So, why do the "Media Wearout Indicator" and the "Total LBAs Written" when using the drive specification limit differ so greatly?
