There has been concern over the amount of write amplification1 while using the Intel® SSD 530 Series and the Intel® SSD 535 Series. It has been noted that the write amplification on the Intel® SSD 520 Series was much lower. The 530 Series and 535 Series added architecture around power savings which changed the behavior of the drive. On some systems this may have write amplification impacts; however, the drive was also architected to meet the same reliability and endurance standards as the 520 Series.

Some write amplification is expected. Because of the architecture of NAND, while other drive activity is occurring, the drive will perform garbage collection moving “in use” data to new areas and reclaiming deleted blocks as free space. The amount of write amplification depends on the type of writes and amount of deleted data. Certain workloads trigger a higher write amplification. For instance, small-file-size write operations over long periods of time generate more garbage collection than large –file-¬size write operations. The power saving modes in the 530 and 535 Series products also add extra background write operations before taking the drive into a lower power state. If the drive is transitioning into lower power and then being woken up very frequently, the number of background operations increases, and in effect, increasing write amp. Standard user activity is typically a mix of write behavior (not only small IOs) with power saving transitions spread out over time.

If your typical activity is not approaching the endurance rating as specified in the Product Specification, you should have no concern of excessive wear out on the Intel SSD. Should you be concerned about wear out, please monitor the SMART attribute E9h. Intel warranties the SSD based on the consumer adhering to usage as based in the Product Specification.
