When considering upgrading my storage, the Transcend M.2 SSD 400S stood out for several reasons. Firstly, its ultra-compact dimensions and SATA III 6Gb/s interface make it an excellent fit for slim and portable devices, especially Ultrabooks and sleek notebooks. The MLC NAND flash memory paired with a DDR3 DRAM cache ensures a smooth performance for most tasks.

  • Ultra-compact design suited for small form factor devices

  • Utilizes SATA III 6Gb/s interface for fast data transfer

  • Space-saving M.2 Type 2242 form factor

  • Mlc NAND flash memory and DDR3 DRAM cache

  • Supports DevSleep Ultra low power state, S.M.A.R.T., TRIM, and NCQ commands

The storage capacity of up to 32GB might seem modest compared to what is currently available in the market, but it’s ample for operating systems and essential applications. The support for advanced functions like Device Sleep Mode (DevSleep), which significantly extends battery life when inactive, is a crucial feature for mobility.

I was particularly impressed with the SSD’s read and write speeds (up to 500MB/s and 450MB/s, respectively) that the M.2 SSD 400S handles with ease, it proved to be significantly faster than a standard hard drive. Moreover, it provides an admirable 4k random file read and write IOPS of 70,000, which is a notable spec for heavy graphics and multimedia applications.

While I found the storage capacity ideal for my ThinkPad’s two-drive setup, the 32GB capacity could be restrictive if you’re looking to store a large volume of data directly on the drive. I have to admit, a 1TB option, if it was available at the time, would’ve been better for a vast storage requirement.

One minor issue was the heat generation during initial use, which seems to be a common trait in compact SSDs. However, this settled after a short period, and the performance remained consistent. Despite the excellent durability and error correction features, the pricing is a factor to consider; the SSD comes with a premium and may weigh a bit heavy on the wallet, especially when you compare it to larger capacity options from other brands that provide a better cost-per-gigabyte ratio.

In summary, from my personal use, the Transcend M.2 SSD 400S met the expectations for a high-performance, small form factor SSD. For those working with slim line notebooks or Ultrabooks and requiring an internal drive upgrade that doesn’t sacrifice performance for size, this SSD might be the right fit. However, the price and lower capacity could be a trade-off for some.
