The Asus Zenbook A14 UX3704NA leads subnotebook storage performance with a peak read speed of 10,313.9 MB/s, according to recent benchmark data. This performance marks a significant leap over the subnotebook class average, which ranges from 694 to 13,544 MB/s over the last two years.
SSD Performance Divergence in 14-Inch Subnotebooks
Storage speeds in the current subnotebook market show extreme variance. The Asus Zenbook A14 UX3704NA dominates high-end read benchmarks at 10,313.9 MB/s. In contrast, the Samsung Galaxy Book5 Pro 14 940XHA, utilizing the Samsung PM9C1 MZVL8512HELU, recorded a significantly lower 5,008 MB/s in the same category.
Did you know? The Asus Zenbook A14’s peak performance is nearly double that of the Samsung Galaxy Book5 Pro 14 in specific high-speed read tests, illustrating the massive range of “Gen4” performance in modern laptops.
Comparative Analysis: Top Performers vs. Class Averages
The Honor MagicBook Pro 14 2026, equipped with the YMTC PC411-1TB, shows strong versatility, hitting 4,761 MB/s in mid-range tests and 6,927 MB/s in high-end reads.
| Device | Drive Model | Peak Read Speed |
|---|---|---|
| Asus Zenbook A14 | Micron 2600 1TB | 10,313.9 MB/s |
| Honor MagicBook Pro 14 | YMTC PC411-1TB | 6,927 MB/s |
| Asus ZenBook S14 | Samsung PM9C1b MZVL81T0HFLB-00BTW | 7,018 MB/s |
The Impact of Drive Selection on Real-World Use
The choice of SSD manufacturer—ranging from SK hynix and Micron to Samsung and YMTC—creates distinct performance profiles. For instance, the Lenovo Yoga Slim 7 Ultra 14IPH11 uses the SK hynix PVC10, which delivered 6,602 MB/s in high-end reads, placing it slightly below the subnotebook class average.
Lower-performing drives, such as the one found in the Dell XPS 14 Core Ultra 7 (SDFPMSL-512G-1101), recorded read speeds as low as 1,981 MB/s in certain tests. This 17% drop below the average suggests a focus on power efficiency or a different tier of NAND flash.
Pro Tip: When shopping for a subnotebook, don’t rely solely on the “PCIe 4.0” label.
