If you are not using SSD in your laptop or desktop PC in 2019, you are definitely missing out. There is very little reason not to insist on one, even if your budget is exactly below. At the bottom end of the market, 120 or 240GB of storage space is enough for casual users, and the SSD speed advantage gives the ability to spinning hard drives. Your PC will boot up and fall asleep quickly, programs launch without waiting for you, and better accountability makes you more productive overall.

Kingston is one of several companies that provide reasonably-priced SSDs at the lowest possible prices. It competes with WD, Adata, Samsung, Zotac and Transcends in the Indian market, but interestingly, it has a two-pronged strategy. The A400 series and the UV400 series both have very similar specifications and cost much more, but there are some differences that we'll get to later.

Today, we're going to test the Kingston A400 240GB model to see if it fulfills its promise, and what you can realistically expect from it.

Kingston A400 Specification and Features

The Kingston A400 is a standard 2.5-inch SATA SSD, but you can see it aimed at the commodity market. For starters, it comes in the simplest packaging we've ever seen; A thin cardboard and plastic bubble pack. There is no padding, although having a proper SSD is not susceptible to damage during shipping. You get nothing else with it - no SATA cable, no screws, and no adhesive shim. This is a bit surprising as such drives are usually aimed at the upgrade market, and a shim helps the 7mm thick SSD to fit in places designed for older laptops like 9.5mm thick hard drives.

The drive itself is only a plastic box with the Kingston logo engraved on the surface. A small sticker on the back is mandatory regulatory information. Of course, there is no difference for the internal SSD, but we are left with the impression that Kingston has cut every possible corner to reduce the price.

You can buy A400 in 120GB, 240GB and 480GB capacities. In terms of performance, all three are rated at 500 Mbps for sequential reads but have different write speeds: 320 Mbps, 350 Mbps, and 450 Mbps, respectively. As expected, this planar uses a TLC flash. The formatted capacity of our 250GB unit was 223.44GB.

TBW (written terabytes) gives buyers an idea of ​​the useful life they can expect from their purchase, and the figures are 40TB, 80TB and 120TB, respectively, for the three capacities. Kingston also specifies 1 million hours as MTBF (time between failures), which is more than enough for a single consumer drive. You will get a three-year warranty with each drive.

One of the things that contributed to the low price of the A400 is that Kingston does not use an exact controller, and this is something that may change with future modifications. Everything that the spec sheet says "2ch controller" is being used. This is the key difference between the A400 and UV400 - Kingston specifies that the latter here uses a four-channel Marvell 88SS1074 controller. The UV400 is also available in a 960GB capacity, which has a slightly higher speed and TBW rating than its A400 counterparts.

Kingston A400 Performance

As usual, we used CrystalDiskMark to test the performance of this SSD. Using a queue depth of 32, the serial read and write speeds came down to 555.9Mbps and 507.2Mbps, respectively, which saturates the SSD's controller to achieve the most efficiency. These scores exceed Kingston's published ratings but are more indicative of best-case scenario performance. Random read and write speeds came in at 321.9Mbps and 310.2Mbps respectively.

Without the benefit of queue depth, sequential read and write speeds were 502.1Mbps and 490.6Mbps, while random speeds were 25.38Mbps and 86.67Mbps, respectively. These are still great scores, and the way performance is tight, it will be with spinning hard drives. SiSoft SANDRA's physical disk and file system tests gave us comparable results.

Overall, the score is slightly lower than those we saw with the 250GB WD Blue SSD we tested a while back.
