ZhiTai Ti600 SSD Review: Budget PCIe 4.0 NVMe — Gen 4 Speed on a Gen 3 Budget

ZhiTai Ti600 SSD has 50,000+ reviews on JD.com with a 4.6/5 rating at ¥479 ($67) for the 1TB version. Users appreciate the affordable entry into PCIe 4.0 NVMe speeds. The main complaints are the DRAM-less HMB design and slower random IOPS compared to premium Gen 4 drives. Conclusion: ✅ Worth Buying — the best entry-level PCIe 4.0 SSD for budget builds and laptop upgrades.

Introduction

The ZhiTai Ti600 is the budget sibling of the TiPlus 7100, sharing the same YMTC NAND heritage but at a significantly lower price point. While the TiPlus 7100 competes with Samsung’s 990 Pro, the Ti600 targets the mid-range segment dominated by the Samsung 980, WD SN770, and Crucial P3 Plus.

The key cost-saving measure is the DRAM-less design using HMB (Host Memory Buffer). This keeps the price at ¥479 for 1TB — about ¥220 cheaper than the TiPlus 7100 — while still delivering PCIe 4.0 sequential speeds that approach 5,000 MB/s.

Design and Build Quality

The Ti600 uses a single-sided M.2 2280 design — all NAND, controller, and passive components on one side. This makes it ideal for laptops with limited clearance. The controller is a MAP1602 (same as the TiPlus 7100) but paired with a budget configuration — fewer NAND channels and no dedicated DRAM.

The graphene heat spreader label is the same as the TiPlus 7100. For a DRAM-less drive that runs cooler than DRAM-equipped drives, the sticker is adequate for most use cases. In testing, idle temperatures hover around 35°C, and under sustained load, the drive reaches about 65°C — comfortably below thermal throttling thresholds.

“Installed this in my Dell laptop as the primary drive. The single-sided design was essential — my old laptop has no clearance for double-sided SSDs. Works perfectly, and the laptop is significantly snappier.” — JD.com verified buyer

The build quality is solid for the price point. The PCB is clean with good solder joints, and the label is professionally printed. It’s not a premium product (no heatsink, no metal enclosure), but it’s well-made for ¥479.

Performance

In CrystalDiskMark, the Ti600 achieved sequential reads of 4,950 MB/s and writes of 4,450 MB/s — close to the advertised 5,000/4,500 MB/s. Random 4K performance at QD32 was 620K IOPS read and 580K IOPS write — respectable for a DRAM-less drive.

The SLC cache is approximately 150GB, writing at full 4.5 GB/s speed. After exhaustion, direct TLC write speed drops to approximately 800 MB/s. This is the HMB limitation — without DRAM, the drive relies on system memory for the mapping table, which adds latency during sustained writes.

In real-world use — game loading, application launches, OS boot — the Ti600 feels nearly identical to DRAM-equipped Gen 4 drives. The difference is only apparent in benchmarks and large sustained file transfers.

“For my gaming PC, this drive loads games just as fast as my friend’s Samsung 980 Pro in blind testing. Cyberpunk 2077 loads in about 9 seconds. At ¥479, the value is incredible.” — JD.com verified buyer

User Reviews by Theme

Theme 1: Price-to-Performance

“Gen 4 speeds at ¥479 is insane value. It loads everything faster than my old PCIe 3.0 drive and cost less than what I paid for that 3 years ago.” — JD.com user 💡 The price-performance ratio is the overwhelming reason users choose the Ti600.

Theme 2: DRAM-Less Performance

“For gaming and regular use, I can’t tell it’s DRAM-less. Sustained large file writes slow down after 150GB, but that’s rare for me.” — JD.com user 💡 Most users find the DRAM-less design has no noticeable impact on daily use.

Theme 3: Laptop Compatibility

“Perfect for laptop upgrade — single-sided, runs cool, and the 1TB capacity fits my ThinkPad perfectly. Huge speed improvement over the original SATA drive.” — JD.com user 💡 Laptop compatibility is a key use case — the low power draw and single-sided design are ideal.

Theme 4: TBW and Longevity

“400TBW for 1TB seems lower than the competition. For office use it’s fine, but heavy video editors might want the TiPlus 7100 with 800TBW.” — JD.com user 💡 The 400TBW endurance rating is noted as a consideration for heavy write workloads.

Purchase Recommendations

✅ Worth Buying: Budget PC builders, laptop upgraders, and anyone moving from a SATA SSD or HDD who wants Gen 4 speed without spending big. The ¥479 price makes it one of the best-value NVMe drives on the market.

💰 Premium Pick: If you regularly write large files, need maximum random IOPS, or want higher endurance (800TBW), spend the extra ¥220 on the ZhiTai TiPlus 7100 at ¥699 ($97) with DRAM cache.

⚠️ Budget Warning: If your system only supports PCIe 3.0, consider saving more with a PCIe 3.0 drive or future-proof with the Ti600 — it will work at Gen 3 speeds now and full Gen 4 when you upgrade your platform.

FAQ

Q1: Is the ZhiTai Ti600 good for gaming? Yes, very good. Game loading times are nearly identical to premium Gen 4 drives. The DRAM-less design has no measurable impact on game loading or level transitions. For a gaming PC, the Ti600 offers excellent value.

Q2: How does HMB (Host Memory Buffer) work? HMB borrows a small portion (typically 64-128MB) of your system’s RAM for the SSD’s address mapping table. This improves performance over fully DRAM-less drives while avoiding the cost of dedicated DRAM. HMB only works on systems with NVMe driver support (Windows 10+, Linux kernel 5.0+, macOS).

Q3: Can I use this as a boot drive? Yes. The Ti600 works excellently as an OS boot drive. Windows 11 installs in about 8 minutes, and boot times are typically under 10 seconds from power-on to desktop.

Q4: How does it compare to the Samsung 980 (non-Pro)? The Ti600 is significantly faster: 5,000 MB/s vs 3,500 MB/s (PCIe 4.0 vs 3.0). The Ti600 has higher TBW (400TB vs 300TB for Samsung 980 1TB). The Samsung 980 has slightly better random IOPS at low queue depths. Overall, the Ti600 is the better value.

Q5: Does this drive support full-drive encryption? It supports hardware-based AES 256-bit encryption, but the implementation varies by platform. Windows BitLocker works using software encryption. For hardware-based encryption, check your motherboard’s TPM and NVMe support.
