Transcend 128GB mSATA SATA SSD

This 128GB internal SSD uses the mSATA form factor and the SATA III 6Gb/s interface. It is built with 3D TLC NAND flash and a DDR3 DRAM cache for faster data access. The drive is designed for ultrabooks, desktops, tablets and other space-constrained systems.

Fits mSATA SATA slots; not for 2.5-inch bays

Select this drive when the host has an mSATA connector that runs SATA signalling. The board measures approximately 1.2 inches by 2 inches and is just 0.2 inches high, so it suits slim devices where a 2.5-inch drive will not fit. Avoid it if the system only accepts 2.5-inch SATA drives or M.2 modules.

550 MB/s sequential read speed

The controller delivers up to 550 MB/s maximum sequential read and 400 MB/s maximum sequential write. Sustained sequential read and write are both rated at 400 MB/s. LDPC error correction and ECC protect data integrity during heavy workloads.

Questions about this item

Will the 128 DDR3 DRAM cache need any maintenance or replacement?

The DDR3 DRAM cache is soldered to the controller and requires no user maintenance or replacement during the drive's life.

What limit appears first during sustained heavy writes?

Sustained sequential write speed settles at 400 MB/s, so the write throughput ceiling is reached before thermal throttling becomes a factor.

How much heat or power does the mSATA 230S produce when running all day?

The compact mSATA form factor draws low power over the SATA III interface and generates minimal heat during continuous operation.
