fanxiang S500 1TB M.2 NVMe SSD (PCIe 3.0): features, specs and who it suits

The fanxiang S500 is a 1TB internal solid state drive in the M.2 2280 format, using a PCIe Gen3 x4 connection and the NVMe protocol. It is meant as a storage upgrade or replacement for laptops and desktops. A drive like this typically replaces a slower hard disk or a SATA SSD to speed up start-up and app loading.

What PCIe Gen3 x4 and NVMe mean

NVMe is a protocol built for flash storage, and PCIe Gen3 x4 describes the connection: four lanes of third-generation PCIe. This is a common standard that most recent laptops and desktops support. fanxiang rates the S500 at read and write speeds of up to 2,100 MB/s, and says its boot time is around 10 seconds. Actual boot time depends on the rest of the computer and the operating system.

3D NAND and capacity

The drive uses 3D NAND TLC flash, in which memory cells are stacked in layers and hold three bits each. TLC is common in mainstream SSDs, and it balances capacity, speed and endurance well for everyday computing. At 1TB there is room for the operating system, applications and a good-sized library of files, photos or games. fanxiang says the drive uses original flash particles, though the listing does not name the flash maker.

Everyday use

A PCIe 3.0 drive like this is typically a large step up from a mechanical hard disk, which is where the faster start-up and quicker file opening come from. It is less about benchmark peaks than about how responsive the computer feels day to day. Compared with PCIe 4.0 or 5.0 drives it is slower on paper, but many everyday tasks do not use the extra bandwidth.

Temperature and cooling

fanxiang says an advanced graphene coating helps manage heat, keeping performance stable under high load. The stated operating temperature range is 0°C to 70°C. Slim laptops can run warm, so airflow around the drive matters regardless of coating.

Compatibility

The listing says the drive works with a variety of laptops and desktops and supports Windows 7, 8 and 10 and Mac OS 10.9 and later. Whether it works in a particular device depends on the slot type. Some older machines use SATA M.2 slots or different key types that are not NVMe compatible.

Size and service

The drive measures 3.1 x 0.9 x 0.1 inches (about 80 x 22 x 2.5 mm), the standard 2280 size, meaning 22 mm wide and 80 mm long. fanxiang lists a 3-year service.

What to check before you buy

• Slot: confirm your device has an M.2 2280 slot that supports NVMe, not SATA only.
• Length: make sure the mounting point or standoff is positioned for 2280 drives.
• Height: single-sided drives fit most laptops, but check the manual.
• Data transfer: plan for cloning or reinstalling the operating system, and back up first.
• Speed expectations: a PCIe 3.0 drive is limited to its own speed even in a faster slot.
• Warranty terms: read what the 3-year service covers.
