Kingston has been one of the prominent brands offering you an excellent performance in the lowest possible pricing. The A400 is a prime offering from Kingston in this genre. It is a standard 2.5 inch SSD and offers you a simple packaging.

The SSD is available in three capacity levels of 120GB, 240GB, and 480GB. While all of them come with a fixed read speeds of 500 Mbps, you get a differential  write speeds at 320 Mbps, 350Mbps and 450Mbps respectively for each of their capacities.

The Comparison: Crucial BX500 vs MX500 vs Kingston A400

Two of the three SSDs we have been discussing here are designed for the low price consumer base. The Crucial BX500 is specifically aimed at providing the lowest possible value per gigabyte.

Let us compare the three SSDs based on the key parameters.

Interface and form factor

The Crucial MX500 is available in two different options in terms of form factors. You have access to a 2.5 inches format along with an M.2 plug in card format. The Crucial BX500 is available only in the 2.5 inch format alone.

The Kingston A400 is also available with the 2.5 inch SATA SSD format. All three SSDs come with the SATA 6 Gb / s or SATA III interface options. That should indicate the same performance in terms of speed.

Performance and speed

The Crucial MX500 provides you access to a read speed of 560 MB per sec and a write speed of 510 MB per sec. The corresponding numbers for the Crucial BX500 are 540 MB per sec and 500 MB per sec. That would make the MX500 slightly better in terms of performance than the sibling BX500.

Kingston A400 will provide you access to 500 MB per sec of read speed and a write speed of 450 MB per sec. This would make it the least option among the three competing devices.

The Capacities

The Kingston A400 is available in three low level capacity sizes. In fact, the SSD is focussed on the price conscious segment and thus is available in 120 GB, 240 GB, 480 GB and 960 GB capacities. The same is the case with the Crucial BX500. It is available in capacities of 120 GB, 240 GB and 480 GB.

The Crucial MX500 is focussed on the high end users. It starts at 250 GB capacity, and there are other higher options available at 1 TB and 2 TB with the M.2 format. The M.2 standard on the Crucial MX500 corresponds to M.2 2280 standard.

Warranty

The manufacturer warranty offered on the Kingston A400 is three years. The theoretical lifetime of the memory cells of the TLC NAND flash memory should ideally come to one million hours. This is in sharp contrast to the Crucial MX500 which offers you a five years of warranty. The Crucial BX500 offers you just three years of warranty as on the Kingston offering. Even in terms of the theoretical lifetime of the memory cells of the TLC NAND flash memory, the Crucial MX500 offers you a better performance than the other two options.

The Comparison Chart for the three SSDs: Crucial BX500 vs MX500 vs Kingston A400

Having gone through those specific options and features offered by the three SSDs, let us now undertake a side by side comparison between them. The head on comparison should provide you with a clear understanding of the features and functions offered by each of the SSDs.

The Concluding Thoughts

That was a complete comparison between the three capable options in the SSD space. Kingston A400 has been specifically designed for the price conscious consumer market and offer a lower cost per gigabyte. The same can be stated about the Crucial BX500.

The Crucial MX500 should be an excellent option for your needs in high end SSD performance. The fact that it is available in multiple form factors should ideally make it a great choice.

In essence, all the three SSDs should provide you access to a better performance and quality. We would find all three of them a great option and definitely recommendable.
