| Data reduction | Data sheet footnote repeats the 5:1 boilerplate, but //ST bypasses deduplication and compression; published effective (294TB / 267TiB) is below raw (409TB / 372TiB) |

| Performance and connectivity | |
| Maximum IOPS | 18,000,000 |
| Maximum throughput | 200 GB/s |
| Latency | 100 µs |
| Conditions | 18M IOPS = 4K reads; 200GB/s = cached reads. Latency: 'consistent sub-100µs' per Pure's Sept 2025 launch blog (data sheet says 'ultra-low'). The FlashArray family data sheet still lists an earlier //ST at 10M IOPS and 102TB/410TB. power_w = typical (3,534–3,675 W typical–peak). Shares the 5U FlashArray//XL chassis; front-end controllers active-active, back-end active-standby. Pure Storage now trades as Everpure; purestorage.com URLs redirect to everpuredata.com. |
