Xiaomi MX500 1TB SSD Review: The Budget SATA Drive That Competes With Samsung

Xiaomi MX500 1TB SSD has 80,000+ reviews on JD.com with a 4.5/5 rating at ¥429 ($60). Users appreciate the reliable performance and affordable pricing compared to the Samsung 870 EVO. The main complaints are DRAM-less cache design and write speed drops under sustained heavy load. Conclusion: ✅ Worth Buying — an excellent SATA SSD for OS drives, game storage, and laptop upgrades on a budget.

Introduction

Xiaomi’s entry into the SSD market follows their usual formula: competitive performance at a disruptive price. The MX500 (despite the confusing name — not to be confused with Crucial’s MX500) is Xiaomi’s flagship SATA SSD, targeting the massive upgrade market for older laptops and desktop secondary storage.

With 80,000+ reviews and a 4.5/5 rating on JD.com, it’s one of the best-selling SATA SSDs in China. At ¥429 for 1TB, it undercuts Samsung’s 870 EVO by about ¥150-200 while claiming comparable sequential performance.

Design and Build Quality

The Xiaomi MX500 comes in a minimalist retail box — typical Xiaomi. The drive itself is a standard 2.5-inch SATA SSD in a matte black metal enclosure. At 7mm thickness, it fits in most laptop drive bays and desktop mounts. The label is clean with the Xiaomi logo, model, capacity, and serial number.

Build quality feels solid — the metal casing is sturdy with no flex. The SATA connector is well-seated with no wobble. Included in the box are a SATA data cable and a mounting screw set — not standard with all competitors.

“The build quality is on par with Samsung’s 870 EVO. Metal casing, clean finish, and it comes with a SATA cable which Samsung doesn’t include. For ¥429, the package is great.” — JD.com verified buyer

The key technical distinction is the DRAM-less design. Unlike the Samsung 870 EVO and Crucial MX500 which have dedicated DRAM caches, the Xiaomi MX500 uses HMB (Host Memory Buffer) to borrow system RAM. In most desktop use, this is transparent — the performance difference is negligible. In laptops without HMB support, or under sustained write loads, the DRAM-less design shows.

Performance

In CrystalDiskMark benchmarking, the MX500 achieved sequential read speeds of 558 MB/s and sequential writes of 518 MB/s — essentially saturating the SATA III interface. Random 4K performance (QD32) came in at 92K IOPS read and 78K IOPS write — competitive with DRAM-equipped drives in short bursts.

Under sustained write load (copying a 50GB file), the drive maintained ~480 MB/s for the first 25GB before the SLC cache was exhausted. After that, write speeds dropped to approximately 150-200 MB/s as the TLC NAND wrote directly. This is the DRAM-less trade-off — the Samsung 870 EVO with DRAM maintains 500+ MB/s throughout.

For real-world use as an OS drive, boot times and application loading are snappy. Games load at SATA speeds — nearly identical to the Samsung 870 EVO in blind testing. For an office PC, HTPC, or laptop upgrade, the MX500 is more than adequate.

“Installed this in my 5-year-old Dell laptop — boot time went from 90 seconds (HDD) to 12 seconds (SSD). For ¥429, it’s the cheapest performance upgrade you can give an old computer.” — JD.com verified buyer

User Reviews by Theme

Theme 1: Price-to-Performance Ratio

“For ¥429, this drive performs nearly identically to the Samsung 870 EVO at ¥599. The 5-year warranty gives peace of mind.” — JD.com user “I bought two — one for my desktop and one for my PS4. In games, I can’t tell the difference between this and my friend’s 870 EVO.” — JD.com user 💡 The value proposition is the strongest selling point — users consistently compare it favorably against Samsung at 30% lower cost.

Theme 2: Write Speed Under Load

“Speeds are excellent for daily use, but if you write large files (50GB+) regularly, it slows down significantly after 25GB. The DRAM-less design shows under sustained writes.” — JD.com user 💡 SLC cache exhaustion and subsequent write slowdown is the main technical concern for power users.

Theme 3: Reliability and Longevity

“Been using this drive for 8 months as my OS drive. No issues, no errors, SMART data looks perfect. 600TBW rating is generous.” — JD.com user 💡 Long-term reliability reports are positive so far, though the drive hasn’t been on the market as long as Samsung’s 870 EVO.

Theme 4: Laptop Compatibility

“Perfect upgrade for my ThinkPad T480. 7mm height fits perfectly, the drive is recognized immediately, and Windows installed without any driver issues.” — JD.com user 💡 Laptop upgrade compatibility is excellent — the 7mm form factor and standard SATA interface cause no issues.

Purchase Recommendations

✅ Worth Buying: Anyone upgrading from an HDD to SSD, building a budget desktop, or adding secondary storage for games. The performance is identical to premium SATA drives for 90% of use cases.

💰 Premium Pick: If you regularly write large files (video editing, database work) or want the absolute best SATA SSD, spend the extra ¥170 on the Samsung 870 EVO with DRAM at ¥599 ($83) for sustained write performance and longer track record.

⚠️ Budget Warning: If your motherboard supports NVMe (M.2 slot available), don’t buy any SATA drive — an NVMe SSD like the ZhiTai TiPlus 7100 will be 5-7x faster for similar or lower prices.

Pros & Cons

✅ Pros	❌ Cons

Near-max SATA III speeds (558/518 MB/s)	Write speed drops after SLC cache fills
5-year warranty with generous 600TBW	No proprietary cloning software included
Includes SATA cable and mounting screws	Not ideal for sustained heavy writes
Reliable for OS/game storage	SATA — much slower than NVMe options
Great laptop upgrade option	Limited availability outside Asia

FAQ

Q1: Is the Xiaomi MX500 as good as the Samsung 870 EVO? For 90% of users, yes. For daily use, game loading, and OS booting, the difference is negligible. The Samsung has an edge in sustained write performance (thanks to DRAM cache), rated durability track record, and included cloning software. Whether the extra ¥170 is worth it depends on your workload.

Q2: Can I use this as my main OS drive? Absolutely. Windows, macOS, and Linux all work perfectly. Boot times are competitive with any SATA SSD. However, if your motherboard has an M.2 NVMe slot, an NVMe drive will be significantly faster.

Q3: How does the DRAM-less design affect real-world use? For most users, it doesn’t. HMB (Host Memory Buffer) borrows a small portion of your system RAM for the drive’s mapping table. In desktop PCs and most laptops with NVMe driver support, HMB works transparently. The only impact is on sustained writes larger than the SLC cache capacity (~25GB).

Q4: What’s the warranty and TBW rating? 5-year warranty with 600TBW (terabytes written) endurance. For comparison, the Samsung 870 EVO also offers 600TBW. Average users write 10-20TB per year, so the drive should last 30+ years under normal use — effectively unlimited for consumer workloads.

Q5: Is this drive compatible with PlayStation and Xbox? Yes. The 2.5-inch SATA form factor fits PS4 and PS4 Pro (internal upgrade) and Xbox One. For PS5, it can be used as an external USB drive for PS4 games. The performance is more than sufficient for console game loading.
