Which of the following can positively impact writer performance?

• A. Hard disk drives
• B. RAID configurations
• C. Running other programs that are writing data at the same time as FME
• D. Solid state drives

Answer: (D)

Writer performance often hinges on how quickly data can be written to storage. Solid-state drives stand out here because they deliver much faster write speeds and lower latency than traditional spinning disks. With no moving parts, SSDs have higher IOPS and near-instant access times, so FME’s writer spends less time waiting for data to be written and can push through large datasets more quickly. This makes SSDs a clear boost for write-heavy workflows.

Hard disk drives do provide storage, but their mechanical nature introduces seek latency and lower throughput, so they won’t boost performance as much as SSDs. RAID configurations can help in some scenarios by distributing or protecting writes, but they also add complexity and can incur write penalties depending on the level used, so they’re not a guaranteed improvement. Running other programs that write data simultaneously creates contention and typically reduces writer performance rather than increasing it.

In short, the faster, lower-latency characteristics of solid-state drives most consistently improve writer performance for FME.
