Acer FA100 vs Sabrent Rocket Q4: Comparison
What is the difference between Acer FA100 and Sabrent Rocket Q4?
On sequential read the spread is 30%, Acer FA100 3300 MB/s against Sabrent Rocket Q4 4700 MB/s, so Sabrent Rocket Q4 takes it. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 5.5, a 14% lead. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 2000 MB/s on the Sabrent Rocket Q4, and the pattern holds. Bus interface is not the same on both, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4, NVMe on the Sabrent Rocket Q4. They differ on nand type too, TLC on the Acer FA100 versus QLC, DRAMless on the Sabrent Rocket Q4.
Acer FA100 vs Sabrent Rocket Q4: which one fits your build
The Acer FA100 suits everyday storage use where 3300 MB/s reads are fast enough. The same goes for budget laptop or desktop upgrades wanting 2000 GB on a PCIe 3.0 x4 M.2 slot. It is not the one for buyers wanting PCIe 4.0 performance, as this drive is limited to 3300 MB/s reads. Take the Sabrent Rocket Q4 for buyers who need maximum storage capacity for archival, media libraries, or read-heavy workloads at the lowest cost per terabyte. QLC NAND makes this drive's high capacities genuinely affordable. It is the wrong buy for buyers running sustained heavy write workloads like large video exports. The Sabrent Rocket 4 Plus, covered elsewhere on this site, handles that scenario far better.
Where the two are identical
Where they agree, they agree completely, form factor and drive type included, so the decision does not turn on any of those.
