mSATA 500GB drive for compact upgrades

This 500GB internal SSD uses the mSATA form factor and a SATA III interface. It targets laptops and small-form-factor PCs that lack 2.5-inch bays but have an mSATA slot. The Samsung MEX controller manages TLC memory for consumer workloads.

3.8mm height fits tight slots

At 3.8mm tall the board slides into standard mSATA connectors without forcing adjacent components. The SATA III link delivers up to 540MB/s sequential read and 520MB/s sequential write. Random performance reaches 98,000 IOPS read and 90,000 IOPS write at 4KB.

Replaces mechanical drives in mSATA systems

Moving from a spinning disk to this drive cuts boot and load times while drawing 0.055W idle and 0.145W active. The 1,500,000-hour MTBF and 0°C to 70°C operating range suit daily mobile use. The jump is worth it when the platform only accepts mSATA.

Questions about this item

What does the SATA III interface cap the Samsung 840 EVO mSATA at in practice?

The SATA III link limits the MZ-MTE500BW to 540MB/s sequential read and 520MB/s sequential write, with 98000 IOPS random read and 90000 IOPS random write.

What physical space does the 3.8mm tall mSATA module need to fit?

The drive measures 30.0mm wide, 50.8mm deep and 3.8mm high, weighing 9g, so it fits any standard mSATA slot with that clearance.

How is the Samsung MZ-MTE500BW installed, and which step catches people out?

Slide the mSATA card into the slot at an angle, press it flat, and secure it with the single screw; the step often missed is fastening that screw so the drive stays seated.
