This article covers Crucial 3D NAND TLC SATA 2.5inch SSD MX500シリーズ 250GB CT250MX500SSD1JP.

Overview

The Crucial MX500 250GB (CT250MX500SSD1JP) is a SATA 2.5-inch internal SSD built with Micron 3D TLC NAND flash. It delivers sequential read speeds up to 560 MB/s and write speeds up to 510 MB/s, effectively saturating the SATA III interface. With a 250GB capacity, it serves well as an OS drive or secondary storage for budget-conscious builds.
This SSD features a DRAM cache, which ensures consistent random access performance compared to DRAM-less alternatives. It also includes Crucial's data protection and error correction technologies, making it a reliable choice for long-term use. Since it uses the SATA interface, it can be easily installed in older laptops and desktops that lack M.2 slots.
In the market, the MX500 sits in the entry-to-mid-range SATA SSD segment. While it doesn't match NVMe speeds, its broad compatibility and excellent price-to-performance ratio keep it popular among users upgrading legacy systems or building on a tight budget.

Compatibility Guide

  • Form factor: 2.5-inch, 7mm thickness — fits standard 2.5-inch bays in laptops and desktops.
  • Interface: SATA III (6Gb/s), backward compatible with SATA II (3Gb/s) but performance will be limited to SATA II speeds.
  • Power: Powered via the SATA power connector; no additional cables needed.
  • OS support: Works with any OS that recognizes SATA controllers, including Windows, macOS, and Linux.
  • Note: This drive cannot be installed in an M.2 slot. For ultra-thin laptops without a 2.5-inch bay, an external USB enclosure is required.

Product Info

The Crucial MX500 250GB uses Micron 3D TLC NAND and has been on the market since 2018, remaining a consistent seller. It comes with a 5-year limited warranty or until the TBW (100TB) is reached, whichever comes first. The retail price is around $40–$50 USD (or roughly 4,000–5,000 JPY), offering excellent value.
Market positioning: entry to mid-range. Despite NVMe becoming mainstream, the MX500 retains a loyal following due to its SATA compatibility and reliability, especially for upgrading older PCs. The inclusion of a DRAM cache gives it an edge over DRAM-less SATA SSDs in random performance.

Best Use Cases

  • Users upgrading an old laptop or desktop from an HDD: Swapping a mechanical drive for this SSD dramatically improves boot times and application loading. Installation is straightforward with a SATA connection, and OS reinstallation is smooth.
  • Budget PC builders: A 250GB OS drive is sufficient for Windows and essential software, leaving budget for other components. It also works well as a secondary drive in gaming rigs.
  • Systems without M.2 slots: Older motherboards and some laptops lack NVMe support. The MX500 provides a reliable, high-performance storage solution for such platforms.
  • Not suitable for: Users needing large storage capacity (e.g., game libraries, video editing projects) or those who require NVMe-level transfer speeds for frequent large file transfers. For those cases, consider a larger NVMe SSD.

Things to Consider

  • The 250GB capacity fills up quickly once you install the OS and a few applications. You'll need additional storage for games or media files.
  • SATA III's maximum throughput (~560 MB/s) is a fraction of what NVMe offers. If you demand the fastest possible storage performance, look at NVMe M.2 drives.
  • Very old motherboards may only support SATA II (3Gb/s), cutting performance in half. Check your motherboard's SATA specification before purchasing.
  • Competitors include the Samsung 870 EVO and WD Blue SA510. The MX500 stands out with its DRAM cache for stable random performance, but its TBW rating (100TB for 250GB) is lower than some rivals, so heavy write workloads may wear it out faster.

FAQ

Q: Can I use this SSD in a PS4 or Xbox One?
A: Yes, as a 2.5-inch SATA drive it works internally in PS4 and externally via USB enclosure for both consoles. However, it cannot be used as internal storage in PS5 (which requires M.2 NVMe).
Q: How does it compare to a DRAM-less SATA SSD?
A: The MX500's DRAM cache provides more consistent random read/write performance, especially under sustained loads. DRAM-less SSDs are cheaper but may slow down during heavy write operations.
Q: How long will the 250GB model last?
A: The TBW rating is 100TB. For typical home use (10–20GB writes per day), it should last over 5 years. If you do heavy video editing or server workloads, consider a model with higher TBW for peace of mind.
