Sandisk announced the SANDISK NAS 600 SATA SSD and the SANDISK NAS 800 NVMe SSD on August 20 local time, both engineered for the always-on demands of network-attached storage. The flagship NAS 800 carries a 14,000 TBW endurance rating in its 7.68TB capacity and reaches sequential reads of up to 14,900MB/s over PCIe 5.0. Both lines arrive in September, starting at 179.99 USD (about 29,000 yen).

For NAS drives, endurance matters more than raw speed

A NAS typically runs around the clock while several people read from and write to it at once. Collaborative photo and video editing, backup targets, virtual machine storage: in all of these, writes never really stop. Drop a standard consumer SSD into that environment and lifespan becomes the limiting factor long before performance does.

The usual yardstick for SSD lifespan is TBW, or terabytes written, which indicates how much data can be written within the warranty period. That is precisely the figure Sandisk has pushed up with this portfolio. Anil Moolchandani, vice president of product management at Sandisk, described how the way people use NAS has fundamentally changed, with larger datasets, cross-team collaboration, and systems that must perform continuously. The target buyers are prosumers, creative professionals, and small businesses.

The NAS 600 SATA SSD targets HDD replacement

The NAS 600 is a 2.5-inch, 7mm-thick drive using a SATA 3.0 interface. It ships in 500GB, 1TB, 2TB, and 4TB capacities with 3D TLC NAND.

Sequential reads reach up to 560MB/s and writes up to 520MB/s, with random reads up to 87,000 IOPS and random writes up to 77,000 IOPS. There is an SLC cache but no DRAM cache. Those figures sit close to the ceiling of the SATA interface rather than breaking new ground, and that is deliberate.

Endurance is rated at 350 TBW for the 500GB model, 600 TBW for 1TB, 1,300 TBW for 2TB, and 2,500 TBW for 4TB. MTTF is 2.25 million hours and the warranty runs 5 years. The drive measures 69.85mm wide, 100.5mm deep, and 7mm tall, weighing 34.5g.

Because a 2.5-inch SSD can go into a 3.5-inch NAS bay, owners can swap out hard drives without changing enclosures and gain silence and responsiveness in return. The drive is also designed for stable operation in multi-drive and RAID configurations, which separates it from a typical desktop SSD.

The NAS 800 NVMe SSD aims at all-flash builds

The NAS 800 is an M.2 2280 drive on a PCI Express 5.0 x4 interface, offered in 960GB, 1.92TB, 3.84TB, and 7.68TB capacities with 3D TLC CBA NAND.

Sequential reads hit up to 14,900MB/s and writes up to 13,200MB/s. Random performance reaches up to 2.3 million IOPS on reads and 2 million IOPS on writes. It carries both DRAM and SLC caches, marking a clear design split from the SATA model.

Endurance is where it stands out: 1,750 TBW at 960GB, 3,500 TBW at 1.92TB, 7,000 TBW at 3.84TB, and 14,000 TBW at 7.68TB. That last figure means filling the entire drive every single day for close to 5 years. MTTF is 1.75 million hours, with a 5-year warranty. Dimensions are 22mm wide, 80mm deep, and 2.38 to 3.88mm tall, at 7.5 to 8.8g.

Sandisk lists caching and storage tiering alongside databases, virtualization, content creation, and agentic AI workloads. Demand to keep data local while running AI on it is clearly raising the bar for what a NAS has to deliver. The company says the drive has been tested for M.2 2280 compatibility with many leading NAS systems.

Pricing and availability

Both lines go on sale in September through Sandisk.com and through retailers and e-tailers worldwide. The NAS 600 starts at 179.99 USD (about 29,000 yen) for the 500GB model, and the NAS 800 starts at 309.99 USD (about 49,000 yen) for the 960GB model.

※1 USD = 159 JPY (as of August 21, 2026)

Japanese release timing and local pricing have not been announced. Still, NAS-specific SSDs are a relatively young category that vendors have only recently filled out, so more options are welcome. Anyone who has been running an HDD-based NAS for years has a reason to look closely here.

Summary

Sandisk's NAS storage push comes in two parts: the NAS 600 catches users migrating away from hard drives over SATA, while the NAS 800 chases all-flash configurations over PCIe 5.0. Both carry 5-year warranties, and the top 7.68TB model is rated for 14,000 TBW. They ship in September starting at 179.99 USD, making them a practical option for NAS builds that run continuously under multi-user load.
