The SSD That Survives 100 Drive Writes Per Day — For 5 Years Straight
Every NVMe SSD in this catalog has an endurance rating measured in DWPD (Записей на диске в день). The Samsung PM9A3 is 1 ДВПД. The Kingston DC1500M is 3 ДВПД. The Intel Optane P5800X is 100 ДВПД. Not 10. One hundred. The P5800X writes its entire 1.6TB capacity 100 times every day for five years — 292,000 TBW of total endurance — because it uses Intel Optane memory (3D XPoint), a fundamentally different storage technology with write endurance measured in orders of magnitude beyond NAND flash. For the write-absolutely-everything workloads — OLTP transaction logs, ZFS SLOG/ZIL, Ceph WAL, Kafka streams, database write-ahead logs — the P5800X is the only drive that never becomes the bottleneck and never wears out.

Optane vs NAND — The Latency and Endurance Gap

|---|---|---|---|
| 4K Random Read Latency (QD1) | 2.5 microseconds | 75 microseconds | 30x faster |

Where the P5800X Earns Its Price
- ZFS SLOG/ZIL device: ZFS writes every synchronous transaction to the SLOG before acknowledging. A NAND SLOG at 75 microseconds latency adds that delay to every fsync. An Optane SLOG at 5 microseconds makes fsync nearly free. ZFS deployments with Optane SLOG report 10-20x write latency improvement vs NAND SLOG.
- OLTP transaction logs (SQL-сервер, Оракул): Every commit waits for the WAL write. Optane’s 5-microsecond write latency removes the commit bottleneck — the difference between a database that bottlenecks on disk and one that bottlenecks on the application logic.
- Ceph WAL/DB: Ceph OSDs write WAL and DB to the fast tier. Optane WAL devices absorb the write storm during cluster rebalance without dropping IOPS.
- Write caching tier: For write-heavy workloads where a 3 DWPD NAND drive wears out in 3 годы, the P5800X’s 100 DWPD rating is effectively permanent. It will outlast the server.
