Kingston A400 SSD Review

Kingston A400 SSD is a drive fit for those on a tight budget, but is it the best choice in 2020?

It’s 2020, and by now, everyone should have an SSD, no matter what they use it for. The prices for SSDs are so low it doesn’t make sense not to buy one. We are talking about a faster PC boot speed, sleep speed, programs opening noticeably faster, and improving your overall productivity.

When it comes to reasonable SSDs, we look at Kingston, which has plenty of solid-state drives with different capacities and targeting various markets. Let’s check out the Kingston A400 240GB SSD and see what you can expect from it and if it still is relevant as a purchase in 2020.

At the time of launch – in Q1 2017, the price was around $50 for a 240GB Kingston A400 SSD, but it has now gone as low as around $35 at various retailers. Even with this low price, can it face newer and better SSDs that go for less than $60?

Kingston A400 250GB SSD – PROS AND CONS

+ Pros: affordable, low power consumption, 3-year warranty, solid performance

– Cons: no software tool, not enough performance compared to drives that are slightly more expensive


The Kingston A400 is a standard 2.5-inch SATA solid-state drive. It comes without a SATA cable, with no screws. By the looks of it, Kingston has indeed cut all corners to lower the price tag. Although the Kingston A400 comes in 120GB, 240GB, and 480GB capacities, we chose to talk about the 240GB model.

While the three capacities have the same 500MBps sequential reads, the write speeds differ 320MBps, 350MBps, and 450MBps respectively.

  • Form Factor: 2.5″
  • Capacity: 250GB
  • Interface: SATA Rev. 3.0 (6 Gbp/s)
  • NAND: 3D
  • Controller: Phison PS3111-S11
  • Flash Memory: Toshiba 15nm TLC
  • Data Transfer (ATTO): up to 500MB/s Read and 350MB/s Write (240GB)
  • Warranty & Endurance: 3 years, 1 million hours MTBF, 80TB (TBW)

For a consumer drive, the three-year warranty and 80TB written is more than enough to last you until a further and much-needed upgrade.

And talking about upgrades, does the Kingston A400 SSD upgrade speed and performance compared to other SSDs from 2017? How does it fare against 2018 SSDs? Let’s look at the benchmark results from our tests below.
