The Kingston A400 SA400S37/240G is a 240GB 2.5-inch SATA III internal SSD for users upgrading a compatible desktop or notebook from a hard drive, with sequential read speeds up to 500 MB/s and write speeds up to 350 MB/s.
Recommended For
- Owners of an older laptop or desktop with a 2.5-inch SATA bay who want to replace a mechanical boot drive and make startup and app loading feel more responsive.
- People refreshing a thin or older notebook that needs a 7 mm, 2.5-inch SATA replacement drive and mainly runs an operating system and everyday applications.
- Budget-conscious users who need a basic SATA drive for a lightweight operating-system installation, documents, and a small set of apps rather than demanding storage workloads.
- Notebook owners replacing a mechanical drive who value a light, shock- and vibration-resistant storage device for ordinary mobile computing.
Real-World Use Scenarios
- Replacing a mechanical hard drive in a compatible older laptop or desktop with the A400 can make startup and everyday system response feel noticeably quicker; the exact improvement depends on the computer and its software.
- For everyday school or home-office work on an older laptop—such as opening documents, browsing the web, and launching common apps—the A400 can reduce storage-related waiting compared with a hard drive, though it will not fix limits from low memory or an older processor.
- As a boot drive in a compatible 2.5-inch SATA system, the 240GB A400 can hold the operating system and frequently used apps, making it a practical option when replacing a hard drive or a smaller SSD.
- On an older PC used for light gaming, installing the operating system and a few frequently played games on the A400 can shorten storage-related startup and loading waits; it does not increase game frame rates, and 240GB limits how many large games fit.
- If a computer has a separate drive for bulk storage, the A400 can serve as a 240GB home for the operating system and frequently used apps while larger media files stay on the other drive.

Reference Q&A
Q: Should I replace an old laptop HDD with the Kingston A400 240GB?
A: Choose the A400 if the laptop supports a 2.5-inch SATA drive and 240GB is enough for your operating system and apps. Kingston positions it as an HDD replacement, with rated sequential speeds of up to 500MB/s read and 350MB/s write. Keep an HDD if you need more capacity at lower cost for files that do not need SSD responsiveness.
Q: Kingston A400 240GB or Crucial BX500 240GB for an older PC?
A: Both are 2.5-inch SATA SSDs in the entry-level category. The A400 is a suitable choice when it fits the system and is the better-priced or more readily available option; compare the exact model’s price, warranty, and capacity before choosing. Published BX500 testing shows performance can vary by workload, so advertised sequential speeds alone do not establish a universal winner.
Q: Is the Kingston A400 240GB or 480GB a better buy?
A: Choose the 480GB model if you need more room for applications and files or expect to keep the drive longer. Kingston rates the 480GB version for up to 500MB/s read and 450MB/s write, compared with up to 500MB/s read and 350MB/s write for the 240GB version. Choose 240GB when its lower capacity meets your needs and the price is the priority.
Q: Should I get the Kingston A400 or Samsung 870 EVO for a SATA system?
A: Choose the A400 for a basic, lower-cost HDD replacement when 240GB is sufficient. Choose the Samsung 870 EVO if you want a more performance-focused SATA drive: professional reviews found strong SATA performance, including in small-file and mixed workloads. Confirm that the 870 EVO’s capacity and price justify the upgrade for your use.
Q: Will this SSD fit my laptop or desktop?
A: It fits systems that support a 2.5-inch SATA drive and have the required SATA connection. The drive is 7 mm thick; check your computer’s specifications before buying. A desktop that only has 3.5-inch mounting points may need a mounting bracket.
Q: Can I use it to replace my laptop’s hard drive?
A: Yes, if the laptop uses a 2.5-inch SATA drive. The A400’s 240GB capacity can serve as a replacement drive, but check that your used storage will fit. To keep your existing system and files, you’ll need to clone the old drive; otherwise, install an operating system separately. Cloning software is not specified in the provided product information.
Q: Is 240GB enough storage?
A: It may be enough for an operating system, everyday applications, and a modest collection of files. Check how much space your current drive uses and allow room for future files; 240GB may be limiting if you store many large games, videos, or other files.
Q: Can I install it in a desktop computer?
A: Yes, if the desktop has a compatible SATA connection and power connector. The drive is 2.5 inches; if the case only provides 3.5-inch mounting points, you may need a bracket to secure it.
Q: Is the Kingston A400 240GB a suitable upgrade for an older PC with a 2.5-inch hard drive?
A: It may suit a basic upgrade if the computer supports a 2.5-inch SATA drive and 240GB is enough for your system and files. Reddit and YouTube discussions describe it as a budget option for older systems, but they also note that its performance is entry-level; compare its price with other compatible SSDs before buying.
Q: Is the A400 240GB adequate as a boot drive for basic school or office work?
A: It can be a fit for basic use when the operating system, applications, and files fit within 240GB. Reddit users report both successful light-use setups and problems, so community anecdotes do not establish consistent reliability or performance for every drive.
Q: What is the main trade-off of the Kingston A400 240GB?
A: It is a basic SATA SSD with no dedicated DRAM cache, and its 240GB capacity may be limiting if you keep many large files or applications on the drive. Reddit discussions raise concerns about performance under heavier use and when the drive is nearly full; it is a less compelling choice if sustained writes or ample storage are priorities.
Q: Do user reports suggest a reliability risk with the A400?
A: Reddit reports are mixed: some users describe years of trouble-free use, while others report failures or freezes. These individual accounts cannot predict the reliability of a particular drive; keep backups and avoid relying on the SSD as the only copy of important data.
