  • 3D NAND TLC delivers up to 550MB/s read and 480MB/s write speeds
  • No moving parts for silent operation and shock-resistant reliability
  • TRIM, LDPC ECC and advanced wear leveling protect data integrity over time
  • SLC cache and thermal throttling maintain consistent performance under load

Compact mSATA form factor

The Fanxiang S301 is a 256GB internal solid-state drive built in the mSATA form factor. It uses 3D NAND TLC memory and a SATA interface to deliver solid-state speed for laptops, ultrabooks and small-form-factor desktops that have an mSATA slot. The drive targets users who need a lightweight storage upgrade without the bulk of a 2.5-inch SATA SSD.

Thermal throttling and low power draw

An operating range of -40°C to +85°C and a storage range of -10°C to +70°C show the drive tolerates wide temperature swings. Built-in thermal throttling protects the controller under sustained loads while the absence of moving parts keeps noise at zero and power draw low during normal use.

No moving parts and broad feature set

With no mechanical components the S301 resists shock and vibration better than a traditional hard drive. Supported features include TRIM, SMART, LDPC ECC, advanced wear levelling, bad block management, SLC cache and power management, helping maintain consistent performance and data integrity over the drive’s service life.

Questions about this item

How do I install the S301 mSATA SSD and what step is often missed?

Insert the mSATA card into the slot at an angle then press it down and secure it with the mounting screw; the step often missed is fastening that screw so the drive stays seated.

What maintenance will the 256GB S301 need later?

No scheduled maintenance is required; TRIM, wear levelling and bad-block management run automatically, and SMART tools can monitor health over time.

What limit appears first during sustained heavy writes on this S301?

The SLC cache fills and sequential write speed drops from the 480MB/s peak to the TLC native rate once the cache is exhausted.
