Get This Price

At $509.99, the current price is below its 30-day average of $599.99, the Optimus 5100 reaches its lowest price on record. The recorded low was previously $571.46, while its 90-day average is $597.98 and its 180-day average is $616.23. Those figures put the current offer below both the earlier low and the longer-term averages, giving this price cut useful context beyond the sale badge.

What You're Getting

• 4TB capacity for storing 4K videos, high-resolution images, and other project files on an internal SSD.
• PCIe 4.0 connectivity in an M.2 2280 format, built with Sandisk's eighth-generation BiCS QLC 3D CBA NAND.
• Write speeds up to 6,700MB/s, a quoted specification that applies to the 4TB model included in this deal.
• An endurance rating of up to 1,200 TBW for this capacity, which Sandisk positions for creators.
• A power-efficient design and the downloadable Sandisk Dashboard application for monitoring SSD performance and checking for updates.

Who This Is For

Creators working with 4K footage and high-resolution photography are the clearest fit: the capacity gives those files more room, and the quoted write performance supports the drive's focus on project work. It also suits buyers who have already chosen a 4TB PCIe 4.0 internal SSD and want a price below this model's recorded averages. Choose it for that combination of capacity, format, and performance when those are the requirements of your storage upgrade.

Final Verdict

The $90 reduction makes this a practical purchase for creators who need 4TB of internal storage now, with the lowest recorded price strengthening the case. Get the Sandisk Optimus 5100 for $509.99 if its capacity and PCIe 4.0 specifications match your next upgrade.
