SanDisk launched the NAS 800 NVMe SSD line, with the 7.68TB flagship rated for 14 petabytes written (PBW) over its lifetime—translating to 1 drive-write-per-day (DWPD) capability, allowing users to fill and rewrite the entire 7.68TB capacity every single day for five consecutive years under warranty. The drive ships in M.2 2280 form factor, reaches 14,900 MB/s sequential read and 13,000 MB/s sequential write, and will retail for $2,199.99 when it becomes available in September.
These endurance numbers eclipse typical NAS SSDs, which cap around 5,000 TBW, and rival enterprise-grade drives (which often exceed 10,000 TBW). For context, consumer SSDs usually max out near 2,500 TBW; SanDisk achieved this through aggressive over-provisioning (~14.5%), optimized firmware, and high-cycle NAND, enabling a write-amplification factor near 1.16X. The NAS 600 SATA line offers lower performance (560 MB/s sequential read/write) but caps out at 2,500 TBW for the 4TB SKU.
For architects: NAS-grade endurance matters for always-on inference clusters or real-time log/telemetry ingestion. 14,000 TBW signals confidence in data-center-grade write durability; cost-per-TBW stays premium ($157/TBW for the 7.68TB), but the 5-year warranty and per-day fill capability appeal to dense storage deployments.
