Acer FA100 vs Sabrent Rocket Q4: Comparison
What is the difference between Acer FA100 and Sabrent Rocket Q4?
The gap that matters here is sequential read: Acer FA100 3300 MB/s against Sabrent Rocket Q4 4700 MB/s, which puts Sabrent Rocket Q4 30% ahead. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 5.5, a 14% lead. Acer FA100 also leads on sequential write, 2700 MB/s on the Acer FA100 versus 2000 MB/s on the Sabrent Rocket Q4. There is a split on bus interface as well, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4, NVMe on the Sabrent Rocket Q4. Nand type is not the same on both, TLC on the Acer FA100 versus QLC, DRAMless on the Sabrent Rocket Q4.
Which should you buy, Acer FA100 or Sabrent Rocket Q4?
The Acer FA100 is the one to take for everyday laptops and desktops with a PCIe 3.0 M.2 slot. It is equally the pick for budget upgrades needing 2000 GB of NVMe storage in a standard M.2 2280 slot. Avoid it for anyone wanting PCIe 4.0 speeds, since this drive tops out at 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 not the one 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
Everything else lines up. Form factor and drive type read the same on both, so those are not worth weighing.
