Transcend 240GB M.2 SATA SSD

This 240GB internal solid-state drive uses the M.2 2280 form factor and a SATA III 6Gb/s interface. It is built with 3D NAND flash and SLC caching technology to serve compact laptops and desktops needing a straightforward storage upgrade.

SATA III interface limits

The SATA III connection caps maximum sequential throughput at 6Gb/s, so real-world speeds cannot exceed this bus limit regardless of the drive's internal capability. Random 4KB performance reaches up to 65,000 read IOPS and 85,000 write IOPS within that constraint.

560 MB/s maximum sequential read

The drive's peak sequential read speed is rated at 560 MB/s, with sequential write up to 500 MB/s. This single figure determines whether the drive meets the throughput requirement for a given SATA-based system.

商品問答

Should I choose the 120GB or 240GB version of the Transcend MTS420S?

The 240GB model provides twice the storage of the 120GB version while keeping the same M.2 2280 form factor and SATA III interface.

What does the 560 MB/s sequential read figure mean when the drive is installed in my laptop?

It represents the peak throughput the controller can deliver over the SATA III link; real-world speeds will be lower and depend on the system workload and file sizes.

The drive uses a SATA III interface — what does that limit in practice?

The SATA III 6 Gb/s connection caps maximum sequential transfer at roughly 560 MB/s, so the drive cannot exceed that ceiling even if the flash memory is faster.
