The choice of storage capacities is shifting from smaller boot drives, such as 240GB or 500GB to larger SSDs of 1TB or more. HDDs are now mainly used for archiving and backup purposes rather than as primary storage. 1️⃣.

Migration Direction Preferences 💡Top 3 migration flows: - SSD to USB (32.2%): Likely reflects data backup or portability needs, where users move data from faster SSDs to external drives for safekeeping. - SSD to SSD (28.1%): Suggests upgrades to larger/faster SSDs or move SATA to NVMe. - HDD to USB (13.6%): Indicates users extracting data from old HDDs to external storage, possibly before disposal or reuse. 💡Lower but notable flows: - HDD to SSD (10.6%): Traditional upgrade path for performance improvements.

SSD to HDD (7.2%): Less common, likely users with large-capacity HDDs for archiving. - USB to SSD/HDD (not listed in top 5): Very low, showing external drives are rarely the source disk. 👉 Interpretation: - Users with SSDs prioritize either speed upgrades (SSDtoSSD) or portability/backups (SSDtoUSB). - HDD users mostly retire old drives by copying to USB or upgrade to SSD without losing data. - Very few cases of downgrading to HDD, except for bulk archiving. 2️⃣.

Source Disk Capacity Distribution Most common sizes: - 1TB (932GB) to 19.4% - 500GB (466-477GB) to 25% combined - 240GB (239GB) to 11% - 2TB (1864GB) to 8.3% 👉 Interpretation: - 1TB and 500GB drives dominate, reflecting mainstream purchase trends over the past 5-7 years. - 240GB drives are often entry-level SSDs, likely being replaced or upgraded. - 2TB+ drives are less common, mainly HDDs used for bulk storage. 3️⃣. C Partition (System Partition) Capacity Popular ranges: - 930GB to 7% (likely whole SSDs or misconfigured single-partition setups).

238GB to 6.3% (common boot SSD size). - 466-465GB to 8.7% combined (mid-tier SSD/HDD partitions). - 1864GB to 5% (large system partitions, often HDDs). 👉 Interpretation: - Many users install OS on 240GB or 500GB SSDs, a common configuration. - The 930GB+ system partitions suggest users with large SSDs dedicated entirely to OS + apps (gamers, creators). - Smaller boot partitions indicate older hardware or budget systems. 4️⃣. Combined Insights SSD users: - Upgrade path is 240GB/500GB to 1TB+ SSD, reflecting growing storage needs (games, media).

A significant portion still offloads data to USB, hinting at backup habits rather than cloud reliance. HDD users: - Still common at 1TB+, but transfer directions show a gradual shift to SSDs. - Many HDD-to-USB flows suggest data salvage from aging drives. Capacity-driven behaviors: - Small system SSDs ( 300 MB/s. - HDD to SSD and SSD to HDD: moderate levels but with noticeable variance, and only ~10% of cases exceed 300 MB/s.

USB-involved transfers: show consistently poor performance, with 67.5% of 'USB to USB' records below 50 MB/s. In addition to the migration medium, there are many discussions on Reddit about the transmission time under different data volumes. While smaller system volumes (120–250GB) are often completed within ~1 hour, migrations involving 500GB typically take 1–2 hours, and 1TB migrations extend to 2–3 hours. For enterprise-grade or 2TB+ environments, the process can last 4–8 hours or more, especially when retries occur due to errors.

4.2 Anomaly and Bottleneck Analysis Extreme cases of both very slow and unusually fast system migrations are frequently observed: - Slow Extremes ( 500 MB/s): Seen in SSD migrations (37 records at 500-1,000 MB/s), driven by NVMe interfaces and optimized caching. HDD peaks (17 records) reflect rare high-performance SATA configurations. - Bottlenecks: USB enclosures introduce latency (up to 50% speed drop), while large file transfers (>500GB) strain caching, reducing effective throughput by 20-30% across all media. Concurrent system processes also degrade speeds by 10-15%.

Key factors of migration obstacles: - Interface limits: USB 2.0 and low-quality enclosures are major bottlenecks. NVMe and SATA III enable fast migrations. - Cache: Cache and controller performance on the target SSD. - File type composition: OS-only migrations complete faster than mixed OS + large media/data workloads. 4.3 User Experience Implications Migration speed significantly shapes user satisfaction during system migration. While users may not track exact MB/s rates, they feel the impact through wait times and perceived reliability.

Data from 132,000 operations shows that slow transfers, especially below 100 MB/s, lead to frustration. This is most evident in USB-involved migrations, where 67.5% of USB-to-USB cases fall below 50 MB/s, often taking hours for completion. Long wait times amplify user concerns about potential failure. For instance, migrations of 500GB typically take 1–2 hours, while 1TB+ transfers can stretch to 2–3 hours. When speeds dip, users often assume the process has stalled. Failures, occurring in 24% of attempts, compound this issue, as users face both wasted time and data risks.
