Quick Answer

For SA builders on X670, a single 2 TB Gen 4 NVMe (~R1,400–R1,800 at Evetech) is almost always a better choice than RAID0 of two 1 TB drives. RAID0 doubles sequential speed but halves reliability (either drive failing loses all data), adds complexity, and provides near-zero gaming fps benefit. The only case where RAID0 makes sense is sustained large sequential writes (4K video editing, 3D animation) where the doubled sequential write speed is genuinely useful.

RAID0 NVMe: Speed vs Risk on X670

Metric Single 2 TB Gen 4 NVMe RAID0 (2× 1 TB Gen 4 NVMe)
Sequential read 7,300 MB/s ~12,000–14,000 MB/s
Sequential write 6,600 MB/s ~12,000 MB/s
Random read (IOPS) 700K ~700K (no RAID0 benefit)
Game load times Baseline Under 0.5s faster
Data loss risk 1× drive failure Either drive = total loss
Cost at Evetech ~R1,400–R1,800 ~R1,800–R2,200 (2× 1TB)

Random IOPS — which determine real-world OS responsiveness, game texture streaming, and application load times — don't improve with RAID0. Only sequential speeds double. Since games use mostly random I/O, RAID0 delivers no measurable gaming fps uplift.

Who Should Consider RAID0 on X670

  • Video editors cutting 8K or high-bitrate 4K footage who need faster timeline scrubbing
  • 3D animators using NVMe for render cache storage
  • Benchmark enthusiasts demonstrating peak platform throughput

Who should not: gamers, everyday PC users, students, content consumers. The risk-to-reward is poor for any workload that doesn't sustain large sequential writes.

FAQ

Does RAID0 NVMe improve FPS in CS2, Valorant, or Cyberpunk 2077 on X670?

No — CS2, Valorant, and Cyberpunk 2077 are not sequential-read bottlenecked after initial loading. Game fps is determined by CPU and GPU, not storage speed above ~2,000 MB/s. RAID0 has zero fps impact in these titles.

What happens to my data if one drive fails in an X670 RAID0 array?

All data on the array is lost — RAID0 has no redundancy. Because data is striped across both drives, a single drive failure corrupts the entire array. Always maintain an external backup of important data when using RAID0. This is the primary reason to avoid RAID0 for an OS drive.

Can I run Windows OS on a RAID0 NVMe array on X670 in SA?

Technically yes, but strongly discouraged. Windows RAID0 arrays (via Windows Storage Spaces or AMD RAID) require additional setup, have recovery complications after reinstalls, and double the probability of OS drive failure. Run Windows on a single drive in M.2_1 and use RAID0 only for scratch/cache storage if needed.

TIP

RAID0, spend the second drive's budget (~R900–R1,100) on a larger single Gen 4 NVMe — a 4 TB Samsung 990 Pro at ~R4,000 delivers more practical benefit than RAID0 two 1 TB drives with better reliability and simpler setup.
