SATA vs PCIe 4.0 Comparison
Transfer speed
The Fanxiang S660 PCIe 4.0 SSD delivers significantly higher maximum read speeds than the S101 SATA model. The S660 reaches up to 5000 MB/s, which is nearly ten times faster than the S101’s top speed of 520 MB/s. This large gap matters for large file transfers and loading heavy data. If you move big files often, the PCIe 4.0 interface provides a clear advantage. The SATA drive is limited by its older interface standard. You will notice the difference in how quickly data moves between the drive and your system.
Form factor
These drives use completely different physical shapes and connection types. The S101 is a 2.5-inch drive, which is the standard size for older laptops and desktops. It connects via a SATA cable. The S660 is an M.2 drive that plugs directly into a motherboard slot. The S660 is much smaller and lighter, weighing only 1.06 ounces compared to the S101’s 2.08 ounces. Your choice depends on your device. Older systems need the 2.5-inch SATA form factor. Newer PCs and consoles require the M.2 slot.
Cooling
Thermal management is a key difference between these two models. The S660 PCIe 4.0 SSD comes with a built-in heatsink to help dissipate heat during intensive use. This is important for maintaining performance when the drive gets hot. The S101 SATA SSD does not include a heatsink in its specifications. SATA drives generally run cooler, so they may not need extra cooling. However, the S660’s design ensures it stays stable under heavy loads. If you plan to use the drive in a tight space like a PS5, the included heatsink is a practical benefit.
Cache type
The S660 features an SLC cache type, which helps manage data flow and maintain speed during burst transfers. This caching method can improve responsiveness when writing large amounts of data. The S101 SATA SSD does not list a specific cache type in its provided specifications. SATA drives often rely on DRAM or smaller caches, but without explicit data, we cannot compare them directly. The S660’s SLC cache is a stated feature that supports its high-speed PCIe 4.0 performance. For users who need consistent write speeds, this specification is a notable advantage.
Compatibility
Both drives support different platforms based on their interface. The S101 SATA SSD is compatible with desktops, laptops, and all-in-one PCs running Windows, Linux, or Mac OS. It is a versatile choice for general computer upgrades. The S660 PCIe 4.0 SSD is explicitly marketed for PS5 compatibility and gaming PCs. It connects to various platforms but requires a PCIe 4.0 slot. If you are upgrading a PS5, the S660 is the only viable option. For older PCs without M.2 slots, the S101 is the necessary choice.
Which Fanxiang SSD should you buy
PS5 owners needing fast game loads
The S660 PCIe 4.0 SSD reaches up to 5000 MB/s, which is ideal for PS5 game loading times. It includes a heatsink to manage temperatures during intensive gaming sessions. This drive connects via M.2 and supports NVMe protocols, ensuring your console runs smoothly without thermal throttling issues over long periods.
Users upgrading older desktops or laptops
The S101 SATA SSD uses a 2.5-inch form factor and SATA III interface, fitting standard bays in older systems. It offers 520 MB/s speeds, which is a significant upgrade over mechanical hard drives. It uses 3D NAND TLC chips for reliable daily use and works with Windows, Linux, and Mac OS.
Budget-conscious buyers with legacy hardware
If your computer lacks an M.2 slot, the S101 is the practical choice. It connects via standard SATA cables and provides 1TB of storage. The 520 MB/s read and write speeds handle file transfers efficiently. It is compatible with most desktops and laptops, making it a versatile upgrade for older machines.
