fanxiang S101Q vs S660 SSD Comparison

Both drives score well for usability and receive positive comments about installation. The S101Q is slightly ahead in the usability score and is a straightforward choice where a 2.5-inch SATA bay already exists. The S660 also has strong setup feedback, particularly from PS5 users, but installation depends on access to a compatible M.2 slot and ensuring heatsink clearance. Neither drive requires the same physical installation process.

The designs are purpose-specific. The S101Q is a thin 7mm, 2.5-inch SATA drive weighing 1.6 ounces, suited to systems built around that familiar storage bay. The S660 is a compact M.2 module with a heatsink, made for a PS5 expansion bay or a compatible desktop M.2 slot. The S101Q is more practical for legacy SATA hardware; the S660 uses space more efficiently in modern M.2-equipped systems.

The S101Q has the higher build-quality score and uses a polycarbonate enclosure in a 2.5-inch drive format. It is also stated to be shock resistant. The S660's physical advantage is its integrated heatsink, intended to help keep temperatures low during prolonged intensive use. However, the S660 has the lower build-quality score, so the supplied information does not support treating the heatsink as proof of stronger long-term hardware durability.

The S101Q has the higher durability score and states shock resistance, which is relevant for an internal drive in a portable computer. The S660's heatsink is designed for low temperatures during prolonged usage, but its lower durability score and reports of early failures weaken its long-term case. The available feedback is mixed for both products, so neither should be selected without a separate backup plan.

Neither is a portable drive on its own; both are internal storage products. The S101Q weighs 1.6 ounces and can be used in a SATA-to-USB enclosure according to a review, while the S660 is a 30-gram M.2 module. The S101Q has the slightly higher portability score, but an enclosure, cable, and host compatibility would be needed for external use.

The S101Q focuses on practical SATA-drive features: 3D NAND, SLC cache, TRIM, S.M.A.R.T., ECC, RAID support, garbage collection, wear leveling, and stated shock resistance. The S660 adds platform-specific advantages for gaming, including PS5 positioning, a PCIe 4.0 NVMe M.2 form factor, 2TB capacity, and a pre-installed heatsink. The S660 therefore has the broader feature set for high-performance gaming storage, while the S101Q is more focused on conventional SATA upgrades.

The S101Q has the slightly higher setup score and is repeatedly described as simple to install in compatible computers. The S660 is also rated highly for setup, with reviewers reporting that PS5 installation and recognition were straightforward. Before buying, check the computer's slot type or follow PS5 installation guidance, because the drive form factors and connections are different.

Compatibility is a split decision. The S101Q is appropriate for devices with a 2.5-inch SATA connection and is stated to support Windows, Linux, and Mac OS. The S660 is appropriate for a PS5 expansion bay and compatible PCIe M.2 PCs. Both score equally for compatibility, but neither can substitute for the other where the device has only one of these interface types.

The S101Q connects through SATA III 6Gb/s and is stated to be backward compatible with SATA II and SATA interfaces. It supports Windows, Linux, Mac OS, laptops, desktops, and all-in-one computers. The S660 uses PCIe 4.0 through PCIe x4 and is described as compatible with PS5 and PCs. Both have the same compatibility score, but the S660's interface offers greater bandwidth; the S101Q covers a broader range of older SATA-based machines.

The S101Q has the higher power-efficiency score. Its supplied information emphasizes SATA operation and shock resistance but does not provide power-consumption figures. The S660 is intended to remain at low temperatures during prolonged intensive use through its heatsink, but no direct energy-use specifications are provided. A definitive real-world power comparison cannot be made from the available data.

The S101Q leads on value score and has the lower listed price, while review feedback frequently characterizes it as good value for a SATA upgrade. The S660's value proposition is different: its higher-capacity 2TB configuration, PCIe 4.0 performance, PS5 suitability, and included heatsink can justify its role for the right system. It is not better value simply because it has more capacity; buyers should pay for its advantages only if their platform can use them.

Both products are from fanxiang, so the comparison is primarily model-specific rather than brand-to-brand. The S101Q receives the higher brand-trust score, while the S660's lower score reflects concerns in its feedback, including early-failure reports and a disputed flash-type claim on one variant. The brand scores do not remove the need to verify the exact listing, capacity, and service terms.

Both products have strong star ratings and substantial review counts: the S101Q has 4.5 out of 5 from 5,646 reviews, and the S660 has 4.6 out of 5 from 3,650 reviews. The S101Q has the slightly higher customer-satisfaction score, with praise centered on ease of installation, speed, and value. S660 buyers often praise PS5 use, capacity, speed, and the heatsink, but the reported early failures are a notable counterweight.

The S660 has the higher warranty-support score and states five-year quality assurance, as well as five-year EU spare-part availability. The S101Q states three years of after-sales service and lifetime technical support. The S660 therefore has the longer stated coverage period, while the S101Q explicitly mentions ongoing technical assistance. Confirm local eligibility, exclusions, and claim procedures before purchase.
