Enhanced Power-Loss Data Protection. Reduces potential data loss by detecting and protecting data from an unexpected system power loss. The drive saves all cached data in the process of being written before shutting down, thereby minimizing potential data loss

(write cache to NAND)

One of the SSD DC S3700's more unique enterprise-oriented features is the use of capacitors to maintain data integrity during a power failure. Two 35 V, 47 uF capacitors store enough charge to commit all data in the write cache to NAND. The radial electrolytic capacitors are bent into a cutout in the PCB, allowing Intel to free up board space that would have been needed for surface-mount capacitors.

Intel also incorporates sensor logic that periodically checks capacitor health. Any outright failure, or even degraded performance, triggers a SMART event and disables write caching to counter the risk of data loss.

On the 800 GB drive, the controller is flanked by a pair of 4 Gb Samsung DDR3-1600 FBGA RAM packages, totaling 1 GB of cache. Below the controller, you see eight NAND packages, each adding 64 GB of capacity. The other side of the drive features eight more, pushing the 800 GB model's total capacity up to 1 TB.
