fanxiang S500 Pro vs S660 SSD Comparison

Both drives are positively reviewed for ease of installation. The S500 Pro has the higher usability and setup scores, and its package includes screws and a screwdriver. Several reviews call it plug-and-play or straightforward to install in PCs and enclosures. The S660 also performs well here, especially for PS5 users: reviews report that it fits the expansion slot, is recognized quickly, and is simple to install. The S500 Pro wins narrowly for general usability; the S660 is the more convenient choice when the intended device is a PS5.

Both drives use the compact M.2 2280 format. The S500 Pro is notably slim and light in the provided measurements, making it a straightforward fit for compatible laptops and desktops. The S660 retains the M.2 format but adds a 0.39-inch-thick heatsink assembly, which is useful for cooling but requires attention to available clearance. Choose the S500 Pro where a slim M.2 installation is important; choose the S660 where PS5-oriented heatsink integration is the priority.

The S500 Pro uses a slim M.2 2280 design with graphite heat-dissipation stickers and a stated 320TBW endurance figure. The S660 is thicker because it has an integrated heatsink intended to manage temperatures during extended workloads. The S500 Pro has the higher build-quality score, while the S660’s dedicated heatsink is a practical advantage for its PS5-focused role. Long-term confidence is not decisive for either drive: both have reported failures, and the S660 has the lower reliability and durability assessments.

The S500 Pro has the higher durability score and states a 320TBW endurance rating for this 512GB version. Its solid-state design is also described as shock resistant. The S660’s heatsink may help thermal management during long gaming sessions, but its durability score is lower and early-failure reports are a concern. One review concerning a separate 4TB S660 variant also questioned the advertised flash type, so the exact model and capacity should be verified. The S500 Pro is the safer choice in this comparison for durability evidence.

Neither product is portable storage in the usual external-drive sense; both are internal M.2 SSDs. The S500 Pro is the more compact and lighter listed unit, at 0.08 inches thick and 0.06 pounds. The S660 measures 0.39 inches thick due to its heatsink and weighs 30 grams. The S500 Pro is the better choice where thin M.2 clearance or low weight matters, while the S660 accepts a larger profile to provide integrated cooling.

The S500 Pro centers on PC and laptop upgrades, pairing PCIe Gen3x4 NVMe 1.4 connectivity with SLC cache, stated 3D NAND TLC, graphite heat-dissipation stickers, and included mounting hardware. The S660 adds a more gaming-focused package: PCIe 4.0, 2TB capacity, an integrated heatsink, explicit PS5 compatibility, and five-year quality assurance. The S660 therefore offers the more specialized feature set for console expansion, whereas the S500 Pro’s included screwdriver and broader stated operating-system compatibility are useful practical touches for a standard PC installation.

The S500 Pro earns the higher setup score and includes mounting screws and a screwdriver, helping users who do not already have small installation tools. Reviews describe it as easy to assemble and plug-and-play in compatible systems. The S660 also has a strong setup score; buyers frequently report quick PS5 installation, immediate recognition, and an advantage from the pre-installed heatsink. For a general PC installation, the S500 Pro is better equipped in the box. For PS5 installation, the S660 is the more directly tailored product.

The S500 Pro is explicitly presented for desktops, laptops, and all-in-one computers, with stated Windows and macOS support, provided the motherboard has an M.2 interface. The S660 is explicitly positioned for PS5 and PC, and review feedback confirms successful PS5 use. The S660 is therefore preferable for PS5 expansion. The S500 Pro is the more clearly documented option for a laptop upgrade. Neither listing eliminates the need to check the host device’s M.2 slot, physical clearance, and supported PCIe generation.

The S500 Pro specifies PCIe Gen3x4 NVMe 1.4 and explicitly lists Windows 7, 8, 10, 11, macOS 10.9 and later, laptops, desktops, and all-in-one PCs, assuming an M.2 interface is available. The S660 specifies PCIe 4.0 and is explicitly compatible with PS5 as well as PC use. The S660 has the more relevant compatibility statement for a PS5 owner, while the S500 Pro has the clearer laptop and operating-system compatibility information. In either case, buyers should confirm that the device has the required M.2 slot and supports the chosen interface.

Both drives are solid-state NVMe storage products, but the supplied information does not provide comparable power-consumption or standby figures. The S500 Pro has the higher power-efficiency score in the provided data. The S660’s heatsink is designed to support lower operating temperatures during intensive use, which is a cooling characteristic rather than a direct measure of energy consumption. Buyers needing a power-sensitive upgrade should seek device-specific consumption data before deciding.

The S500 Pro is the stronger value choice in the supplied scoring because it combines solid everyday performance, installation convenience, positive customer feedback, and a higher overall assessment. That does not make the S660 poor value: its 2TB capacity, PS5 focus, integrated heatsink, PCIe 4.0 interface, and five-year quality assurance give it a different value case. Choose the S500 Pro when 512GB is sufficient and balanced value matters most. Choose the S660 when its extra capacity and PS5-ready design solve a genuine storage need, while accounting for its weaker reliability signals.

Both products are from fanxiang, so there is no brand-versus-brand distinction. The S500 Pro receives the higher brand-trust score in the provided assessments, likely reflecting its stronger balance of customer satisfaction and reliability indicators. The S660’s lower brand-trust result is influenced by reported early failures and a review concerning a different 4TB variant that disputed the listed flash type. The comparison data does not provide detailed support-history information beyond the stated quality-assurance periods.

Both listings show a 4.6 out of 5 star rating, with the S500 Pro supported by 6,028 reviews and the S660 by 3,650 reviews. The S500 Pro has the higher customer-satisfaction score. Its recurring praise covers value, speed, simple installation, and improved responsiveness, although some failures are reported. S660 buyers often praise PS5 compatibility, capacity, heatsink installation, and quick game transfers, but its review overview identifies more serious durability concerns. The S500 Pro has the more favorable customer-satisfaction profile overall.

The S660 has the stronger stated coverage period, with five-year quality assurance and five years of EU spare-part availability listed. The S500 Pro provides three-year quality assurance. This gives the S660 the advantage for stated warranty duration. However, neither listing provides detailed return procedures or replacement terms in the supplied information, so buyers should review seller-specific conditions and retain purchase documentation.
