This article covers Crucial クルーシャル SSD BX500 SATA3 内蔵 2.5インチ 7mm CT240BX500SSD1 (240GB) [並行輸入品].

Overview

The Crucial BX500 series has established itself as a go-to choice for budget-conscious users seeking a reliable SATA SSD. The CT240BX500SSD1 model offers 240GB of storage with sequential read speeds up to 540MB/s and write speeds up to 500MB/s, effectively saturating the SATA 6Gb/s interface. Its 2.5-inch, 7mm-thick form factor makes it compatible with a wide range of devices, from older laptops to desktop PCs. For users still running mechanical hard drives, this SSD provides a dramatic improvement in boot times and application loading at a very accessible price point. Built with Micron's own 3D NAND flash and a Silicon Motion controller, the BX500 delivers consistent quality. It comes with a 3-year warranty and a 80TB Terabytes Written (TBW) endurance rating, making it suitable for everyday computing tasks and as a secondary storage drive.

Compatibility Guide

Interface: SATA 6.0Gb/s (backward compatible with SATA 3.0Gb/s and 1.5Gb/s). Performance will be limited by the slowest link in the chain, so older SATA II ports will cap speeds. Form factor: 2.5-inch, 7mm thickness. Fits most laptops and desktops with a 2.5-inch bay. Some 9.5mm bays may require a spacer or adapter. Desktop installation requires a SATA data cable and a SATA power cable from the PSU. Ensure your motherboard has an available SATA port. Crucial provides free cloning software (Acronis True Image for Crucial) to migrate your OS and data from an existing HDD. Verify that the SSD capacity is larger than the used space on your source drive before cloning.

Product Info

The Crucial BX500 uses Micron's 64-layer 3D TLC NAND paired with a Silicon Motion SM2258XT controller. It does not feature a DRAM cache, relying instead on the controller's pseudo-SLC caching algorithm to maintain performance. This design choice keeps costs low but impacts sustained random write performance. Positioned firmly in the entry-level segment, the BX500 is the budget counterpart to Crucial's DRAM-equipped MX500 series. The 240GB variant is particularly affordable, making it an ideal upgrade for users on a tight budget or for secondary machines where absolute peak performance isn't critical. Warranty coverage is 3 years from purchase or until the 80TB TBW limit is reached, whichever comes first. For typical light-to-moderate daily use, this translates to several years of reliable service.

Best Use Cases

HDD upgrade for general users: If you're still booting from a mechanical hard drive, the BX500 will deliver a transformative speed boost for everyday tasks like web browsing, office work, and media consumption. It's the most cost-effective single upgrade you can make. However, if you frequently copy large files or run multiple heavy applications simultaneously, consider a DRAM-equipped model like the MX500. Secondary storage for a budget gaming PC: Use a fast NVMe drive for your OS and most-played games, and install the BX500 for older titles, game launchers, and media files. Load times will be slower than NVMe but still vastly better than an HDD. This setup maximizes value without breaking the bank. Laptop HDD replacement: The 7mm height fits most standard 2.5-inch laptop bays. Replacing a slow laptop HDD with this SSD can breathe new life into an aging machine, making it feel snappier for daily tasks. Check your laptop's service manual for drive bay thickness compatibility. Light file server or NAS cache: For read-intensive workloads, the BX500's sequential performance is adequate. However, it is not recommended for write-heavy caching roles due to the lack of DRAM, which can lead to performance drops under sustained write pressure.

Things to Consider

The most significant limitation of the BX500 is the absence of a DRAM cache. This results in noticeably slower random write performance compared to DRAM-equipped SATA SSDs like the Crucial MX500 or Samsung 870 EVO. Under heavy multitasking or when writing many small files, you may experience occasional stuttering or slowdowns. As a SATA drive, its sequential speeds are capped at around 550MB/s, which is roughly five times slower than a typical PCIe 3.0 NVMe SSD. If your motherboard has an available M.2 slot and your budget allows, an NVMe drive will provide a much better long-term experience, especially for gaming and content creation. The 240GB capacity is sufficient for an OS and essential applications, but modern AAA games often exceed 100GB each, so you will quickly run out of space if you plan to install multiple large titles. Consider the 480GB or 1TB variants if you need more room. Be aware that some units sold on third-party marketplaces are parallel imports. These may lack Japanese-language manuals and may come with a store warranty instead of official manufacturer support. Always verify the warranty terms before purchasing. ## FAQ
