# Crucial T700 2 TB: PCIe 5.0 capacity with full E26 IOPS (2026)

The Crucial T700 2 TB is a PCIe 5.0 x4 NVMe SSD built on the Phison PS5026-E26 controller and Micron 232-layer TLC NAND, rated 12,400 MB/s reads, 1,500,000 IOPS, and 1,200 TBW with a 5-year warranty.

Quick answer: The Crucial T700 2 TB delivers the full Phison E26 IOPS ceiling, a larger SLC write cache than the 1 TB, and 1,200 TBW endurance under a 5-year warranty — all at a price below the T705, which reaches 14,500 MB/s on the same hardware foundation.

## Performance

The Crucial T700 2 TB is rated at 12,400 MB/s sequential reads and 11,800 MB/s sequential writes over PCIe 5.0 x4, verified in CrystalDiskMark tests across multiple published reviews. Random performance at the 2 TB capacity reaches the full Phison E26 ceiling: 1,500,000 read IOPS and 1,500,000 write IOPS, matching the 4 TB model and exceeding the 1 TB model's 1,350,000/1,400,000 rating.

The 2 TB model's larger NAND die count directly benefits sustained sequential write performance. The dynamic SLC write cache is proportionally larger than on the 1 TB model, meaning the drive sustains its full 11,800 MB/s write speed across longer sequential write runs before the cache is exhausted and throughput falls to direct TLC write rates. For everyday workloads — OS operations, gaming, application reads — the drive operates almost entirely within the SLC burst window and the rated speeds apply. For large sustained writes such as rendering outputs or full backup runs, the 2 TB's expanded cache window provides meaningful headroom over the 1 TB.

Sequential reads of 12,400 MB/s are well above the ceiling of any PCIe 4.0 drive and provide bandwidth for DirectStorage-enabled titles. Random 1,500,000 IOPS comfortably handles the small-block access patterns that dominate conventional game loading and OS responsiveness.

## Endurance, TBW & Warranty

Crucial covers the T700 with a 5-year warranty — not the 2-year figure appearing in some database entries. The 2 TB model carries 1,200 TBW (terabytes written), representing the cumulative write budget under the warranty. Coverage expires at whichever threshold is reached first: five years from purchase, or 1,200 TBW of cumulative writes.

At a typical consumer write rate of 30 GB per day, exhausting 1,200 TBW would take approximately 110 years. At a heavier rate of 100 GB per day the figure is around 33 years. Even at 300 GB per day — a sustained professional workload — reaching 1,200 TBW would take over 11 years, well beyond the 5-year warranty period. Only users sustaining 700 GB or more per day will encounter the TBW boundary before the 5-year clock expires; those use cases belong to the 4 TB model with 2,400 TBW. Warranty service is provided through Crucial's regional support channels.

## Pros and Cons

**Pros:**

- 12,400 MB/s sequential reads on PCIe 5.0 x4
- Full Phison E26 IOPS rating: 1,500,000 read and write
- Larger SLC write cache than 1 TB — better sustained write headroom
- 1,200 TBW endurance comfortably within the 5-year warranty
- Micron 232-layer B58R TLC NAND with 2 GB LPDDR4 DRAM cache
- 5-year warranty from Crucial
- Available with or without factory heatsink
**Cons:**

- Superseded by T705 (14,500 MB/s reads) on the same Phison E26 platform
- Double-sided PCB — check M.2 slot component clearance on compact boards
- Requires good M.2 thermal management — E26 throttles without adequate cooling
- No meaningful performance benefit over PCIe 4.0 drives on non-Gen5 platforms
- SLC cache saturation still possible under very large continuous write operations


## Verdict

The Crucial T700 2 TB delivers the full Phison E26 IOPS ceiling, a larger SLC write cache than the 1 TB, and 1,200 TBW endurance under a 5-year warranty — all at a price below the T705, which reaches 14,500 MB/s on the same hardware foundation.

Choose it if you want a PCIe 5.0 drive at 2 TB capacity, can work with 12,400 MB/s reads rather than the T705's 14,500 MB/s, and the price difference justifies the choice. The 1,200 TBW rating comfortably covers any realistic desktop workload within the warranty period.

Skip it in favour of the T705 if peak sequential throughput matters and the price gap has narrowed. Skip it entirely if your platform supports only PCIe 4.0 — a WD Black SN850X 2 TB or Samsung 990 Pro 2 TB delivers equivalent real-world performance at lower cost without the thermal demands of a Gen5 controller.

## Frequently Asked Questions

### What is the TBW endurance of the Crucial T700 2 TB?

The Crucial T700 2 TB carries a rated endurance of 1,200 TBW (terabytes written). This is the cumulative write budget before the warranty coverage expires. At 30 GB per day — a typical consumer workload — exhausting 1,200 TBW would take approximately 110 years, so the 5-year warranty clock will expire first for virtually all users. At 100 GB per day the figure is around 33 years. The TBW boundary only becomes a practical concern above approximately 700 GB per day sustained; users at that level are better served by the 4 TB model with 2,400 TBW.

### How does the Crucial T700 2 TB compare to the 1 TB model?

The 2 TB model benefits from a larger NAND die count, which produces two advantages over the 1 TB. First, it reaches the full Phison E26 IOPS ceiling: 1,500,000 read and write IOPS, versus 1,350,000/1,400,000 on the 1 TB. Second, its dynamic SLC write cache is proportionally larger, meaning the drive sustains full rated write speed across longer burst windows before transitioning to direct TLC write rates. Sequential read and write speeds are identical between the two: 12,400/11,800 MB/s. For everyday use the practical difference is minimal; for users regularly writing large files it is meaningful.

### How does the Crucial T700 2 TB compare to the T705 2 TB?

The T705, released in 2024, is Crucial's current flagship PCIe 5.0 drive. The T705 2 TB reaches 14,500 MB/s sequential reads and 12,700 MB/s writes, versus 12,400/11,800 MB/s on the T700 — approximately a 17% read speed uplift. Both drives use the same Phison PS5026-E26 controller and Micron 232-layer B58R TLC NAND; the T705's speed advantage comes from firmware and controller binning, not a new hardware generation. The T700 typically sells at a lower price and delivers the same fundamental platform characteristics. If the T705 is priced similarly, it is the better choice; if the T700 is meaningfully cheaper and peak sequential speed is not a priority, the T700 2 TB is the practical option.

### Does the Crucial T700 2 TB have a DRAM cache?

Yes. The 2 TB T700 includes a 2 GB LPDDR4 DRAM chip paired with the Phison PS5026-E26 controller. The DRAM stores the drive's logical-to-physical address mapping table in dedicated on-board memory, providing faster and more consistent random access latency than DRAM-less designs that use the Host Memory Buffer mechanism to borrow system RAM via the PCIe link. The 2 GB capacity is sized for the 2 TB NAND pool.

### Is the 2 TB Crucial T700 double-sided?

Yes, the 2 TB T700 uses a double-sided PCB to accommodate the additional NAND dies required for the capacity. Most M.2 slots on consumer motherboards support double-sided drives, but some compact and low-profile boards have component clearance restrictions. Check your motherboard's M.2 slot specification before purchasing — the relevant parameter is sometimes listed as single-sided only in ITX or thin NUC-style designs.

### What warranty does the Crucial T700 2 TB carry?

The Crucial T700 carries a 5-year warranty — not the 2-year figure that appears in some third-party database entries. The 2 TB model's coverage is subject to a 1,200 TBW endurance limit; the warranty expires at whichever threshold is reached first: five years from purchase, or 1,200 TBW of cumulative writes. Warranty service is handled through Crucial's regional support network.

### Does the Crucial T700 work on PCIe 4.0 motherboards?

Yes, the T700 is backward-compatible with PCIe 4.0 and PCIe 3.0 M.2 slots. It installs and operates normally, but the link speed is capped at the slot's maximum: approximately 7,000 MB/s on PCIe 4.0 or 3,500 MB/s on PCIe 3.0. The full 12,400 MB/s read speed requires a PCIe 5.0 M.2 slot. On a PCIe 4.0 platform the T700 offers no advantage over a same-priced PCIe 4.0 NVMe drive.

### Is the Crucial T700 2 TB good for video editing?

Yes, particularly for sustained sequential write workloads that video editing involves. The 2 TB model's larger SLC write cache compared to the 1 TB means it absorbs longer burst writes — proxies, renders, project exports — at the full 11,800 MB/s rated speed before any drop-off. At 12,400 MB/s sequential reads the drive comfortably handles high-bitrate RAW and uncompressed video streams. The 1,200 TBW endurance also provides ample headroom for sustained professional workloads, with the 5-year warranty intact for any realistic video production schedule.
