KINGSTON A400 240GB 2.5 SATA SATA 3 Internal Solid State Drive (SSD)

The KINGSTON A400 aims to offer a massive boost in performance over last-generation mechanical hard disk drives (HDDs). Short of approaching the lightning speeds of NVMe storage, it shortens system boot time, helps launch apps more quickly, and offers improved responsiveness overall. That places it on an even footing as an upgrade or replacement option for existing users looking to give new life to old platforms or enjoy an upgraded experience for computing. But one must note that its SATA 3 interface puts some constraints in comparison to the PCIe interface of NVMe SSDs, which have much higher data transfer speeds. Thus, though it is faster than a HDD, it's not a speedy drive by current standards.

Yes, the KINGSTON A400 series comes in various sizes of capacities to fit various storage requirements and price budgets. That means customers have a choice to make in the capacity size of the storage that would best fit their requirements. Some of the common sizes offered include 120GB, 240GB, 480GB, and even more than these sizes so that users are given some freedom based on what they require as space for storage. 

No, the KINGSTON A400 is not a Gen3 SSD. It's a SATA 3 SSD. The "Gen3" designation is usually used to describe NVMe drives that employ the PCIe Gen3 interface. The KINGSTON A400, however, uses the SATA 3 interface, another technology. So, one should make a distinction between SATA and PCIe-based SSDs. SATA SSDs such as the A400 are restricted to the SATA 3 interface, whereas PCIe NVMe SSDs are much faster as they are directly plugged into the PCIe bus. So, one should be aware of the distinction between the two technologies.

Kingston normally offers 5 years of warranty on their A400 SSDs. However, the warranty duration may varies from place to place and depends on where the product was bought. It is strongly suggested then that one confirm the exact warranty offered by the store or available on Kingston's official site. This will guarantee that you have correct and current information on the warranty duration and coverage. This will avoid headaches in the future if you need to avail yourself of the warranty.

The KINGSTON A400, being a SATA 3 SSD, is limited by the SATA interface limitations. Hence, its data transfer speeds are limited compared to NVMe SSDs. Overall, you should be able to achieve sequential read speeds up to 550 MB/s on this drive, and sequential write speeds up to 500 MB/s. Essentially, these rates are restricted because of the typical SATA 3 SSD performance. They comfortably surpass HDDs, but are far behind NVMe drives. So while undoubtedly more than good enough for general use, it won't be the optimum pick for high-demand applications.

KINGSTON A400 will deliver a perceptible boost in game loading time over a standard HDD, and it will be acceptable for light gaming. But for highly demanding recent games with super quick loading times and little stuttering, an NVMe SSD would be much superior gaming. Moreover, the sizes of recent games have increased like balloons. A 240GB drive fills up overnight with games these days, so space is also a consideration. So, although it is an improvement over a HDD, it's perhaps not ideal for gaming these days.
