# Sandisk NAS 800 Brings PCIe 5.0 and 14,900MB/s to NAS, With the SATA NAS 600 Covering Legacy Bays

by Lyle Smith on August 20, 2026

[Enterprise](https://www.storagereview.com/enterprise)  ◇  [SSD](https://www.storagereview.com/enterprise/ssd)

Sandisk has introduced two SSD families designed specifically for network-attached storage, covering both SATA-based systems and higher-performance NVMe NAS deployments. The Sandisk NAS 600 SATA SSD offers capacities up to 4TB and endurance up to 2,500 TBW, while the [Sandisk NAS 800 NVMe SSD](https://www.sandisk.com/products/ssd/internal-ssd/sandisk-nas-800-nvme-ssd), a PCIe 5.0 drive, scales to 7.68TB with sequential read speeds up to 14,900MB/s and endurance up to 14 PBW.

The two drives address very different parts of the NAS market. The NAS 600 uses the familiar 2.5-inch SATA form factor and can replace hard drives or serve as a cache or storage tier in existing SATA-based systems. The NAS 800 is an M.2 2280 NVMe drive designed for all-flash and hybrid NAS configurations that require substantially higher throughput and I/O performance.

Both drives feature five-year limited warranties and are designed for extended operation in NAS environments.

| **Specification** | **SANDISK NAS 600 SATA SSD** | **SANDISK NAS 800 NVMe SSD** |
| --- | --- | --- |
| Form Factor | 2.5″ SATA/7mm | M.2 2280 |
| Interface | SATA III 6Gb/s | PCIe 5.0 (NVMe) |
| Capacity | 500GB, 1TB, 2TB, 4TB | 960GB, 1.92TB, 3.84TB, 7.68TB |
| Endurance | Up to 2,500 TBW \[4TB model] | Up to 14 PBW \[7.68TB model] |
| Sequential Read/Write (MB/s) | Up to 560/520MB/s \[4TB model] | Up to 14,900/13,200MB/s \[1.92TB model] |
| Random Read/Write (IOPS) | Up to 86K/77K IOPS \[4TB model] | Up to 2.3M/2M IOPS \[3.84TB model] |
| MTTF | 2.25M hours | 1.75M hours |
| Warranty | 5-year limited | 5-year limited |

## Sandisk NAS 600 SATA SSD for HDD-Based NAS Upgrades

The [Sandisk NAS 600 SATA SSD](https://www.sandisk.com/products/ssd/internal-ssd/sandisk-nas-600-sata-ssd) provides a direct solid-state option for NAS systems with conventional 2.5-inch SATA drive bays. Its 2.5-inch/7mm design means it can be installed in compatible systems without requiring an NVMe-capable NAS or M.2 storage slots. Sandisk is offering the NAS 600 in 500GB, 1TB, 2TB, and 4TB capacities. Performance tops out at sequential read and write speeds of 560MB/s and 520MB/s, respectively, on the 4TB model. Random performance reaches up to 86K IOPS reads and 77K IOPS writes.

![SanDisk NAS 600 2]()

The 4TB NAS 600 is rated for up to 2,500 TBW and has an MTTF of 2.25 million hours. The higher endurance is designed for the frequent reads and writes common in NAS environments, including backups, file sharing, and media workloads.

The drive can serve several roles depending on the NAS configuration. In addition to replacing hard drives with solid-state storage, it can be used as an SSD cache or as part of a storage tier. This gives existing SATA-based NAS owners another option for adding flash storage without replacing the NAS itself.

## Sandisk NAS 800 NVMe SSD for Higher-Performance NAS Workloads

The Sandisk NAS 800 NVMe SSD moves into a very different performance class, using a PCIe 5.0 M.2 2280 design and Sandisk TLC 3D NAND. Capacities include 960GB, 1.92TB, 3.84TB, and 7.68TB, providing [all-flash and hybrid NAS configurations](https://www.storagereview.com/news/qnap-quts-hero-h6-0-beta-adds-dual-nas-ha-immutable-snapshots-and-on-prem-ai) with ample capacity per M.2 slot.

![Sandisk NAS 800 NVMe SSD, PCIe 5.0 M.2 2280 drive for all-flash NAS]()

Sequential read performance reaches up to 14,900MB/s, while sequential writes reach 13,200MB/s on the 1.92TB model. Random read and write performance tops out at 2.3 million and 2 million IOPS, respectively, on the 3.84TB model. This gives the NAS 800 a broader range of potential uses than caching alone. Sandisk lists primary storage and storage tiering alongside caching, with workloads including collaborative content creation, databases, virtualization, and AI applications.

The NAS 800 also has a substantially higher endurance rating than the SATA model, reaching up to 14 PBW with the 7.68TB version. Its MTTF rating is 1.75 million hours, and the drive features the same five-year limited warranty as the NAS 600.

![Sandisk NAS 800 NVMe SSD M.2 2280 drive, rear label view]()

Sandisk rates the NAS 800 for continuous 24/7 NAS operation across a 0°C to 70°C operating range (85°C is its non-operating ceiling) and says the drive has been tested for compatibility across a range of NAS systems.

With the NAS 600 and NAS 800, Sandisk now covers both SATA-based NAS upgrades and higher-performance all-flash and hybrid systems. The NAS 600 gives existing SATA NAS users a flash option for primary storage, caching, or tiering, while the NAS 800 adds substantially higher throughput and endurance for more demanding NVMe-based storage workloads.

## Availability

The [Sandisk NAS 600 SATA and NAS 800 NVMe SSDs](https://www.sandisk.com/solutions/network-attached-storage) are slated for release sometime in September. Sandisk’s own store already lists pricing ahead of availability, showing the 500GB NAS 600 at $179.99 and the 7.68TB NAS 800 at $2,199.99, both marked down from list prices of $224.99 and $2,749.99. The NAS push also caps a busy month for Sandisk, which just [taped out its first HBF memory die](https://www.storagereview.com/news/sandisk-tapes-out-its-first-hbf-memory-die-targets-2027-for-inference-product-samples) on the datacenter side.
