Cons
- ✗ SATA III caps it at 500 MB/s - an NVMe drive is 5-10x faster
- ✗ No DRAM cache specified; relies on SLC caching for burst writes
- ✗ 3-year warranty is shorter than the 5-year terms on tier-1 SSDs
- ✗ No TBW or endurance rating published in the listing
Manufacturer description
The fanxiang S101Q is a 4TB 2.5-inch SATA III internal SSD built for anyone who has run out of room on a laptop or desktop drive and wants a single-drive upgrade instead of juggling externals. It uses 3D NAND flash with SLC cache technology, delivering sequential reads up to 500 MB/s and writes up to 470 MB/s over the SATA III 6 Gb/s interface, which is the practical ceiling for the connection. Swapping a mechanical hard drive for this fanxiang SSD cuts boot times, application launches, and shutdown waits noticeably, since there are no moving parts to spin up. The drive supports garbage…
SpecPicks Verdict
SpecPicks scored fanxiang 4TB SATA SSD 2.5'' SSD SATA III 6 Gb/s Internal Solid State… using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. fanxiang's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Frequently Asked Questions
How fast is the fanxiang 4TB S101Q SSD?
It reaches up to 500 MB/s sequential read and up to 470 MB/s sequential write over the SATA III 6 Gb/s interface, which is effectively the maximum any SATA SSD can deliver.
Will this SSD fit in my laptop?
It is a 2.5-inch drive with a 7mm (0.28-inch) z-height, the standard thickness for laptop drive bays, all-in-ones, and desktops. Confirm your laptop has a 2.5-inch bay rather than only an M.2 slot before ordering.
Does it work with Mac and Linux, or only Windows?
fanxiang lists compatibility with Windows, Linux, and macOS. The SATA III interface is also backward compatible with SATA II and SATA I ports, so older machines will run it at their own lower speed.
What warranty comes with the drive?
It includes 3 years of after-sales service plus lifetime technical support from fanxiang. Check the product listing for the current terms and claim process in your region.
Is it worth buying over an NVMe SSD?
Choose this if your machine only has 2.5-inch SATA bays or you need 4TB of cheap bulk storage. If your board has a free M.2 NVMe slot, an NVMe drive will be several times faster for the same capacity.
