# Addlink S68 1TB SSD — In-Depth Review & Specs (2026)

The Addlink S68 1TB is the flagship capacity in Addlink's most affordable NVMe line. Built on the Phison PS5013-E13T — a 4-channel DRAM-less PCIe 3.0 controller — the 1TB model delivers the platform's full performance potential: 2,500 MB/s read, 2,100 MB/s write, and up to 430,000 random write IOPS. At 1TB the S68 becomes a genuinely practical single-drive solution, combining adequate NVMe performance with a full terabyte of capacity and a 5-year warranty. This review examines whether the S68 1TB overcomes the Phison E13T platform's limitations at its maximum capacity.

Quick answer: The Addlink S68 1TB is the capacity play in the ultra-budget NVMe segment. The Phison E13T DRAM-less platform is not a performance leader — 2,500/2,100 MB/s is adequate rather than impressive by PCIe 3.0 standards — but at 1TB with a 5-year warranty and 800 TBW endurance, the S68 delivers exactly what budget buyers at this capacity care about: a full terabyte of NVMe storage with warranty coverage that outlasts most competitors. For a single-drive budget build where maximizing capacity-per-dollar matters more than chasing benchmark numbers, the S68 1TB is a sensible, warrantied choice. For users who can stretch the budget, the S70 1TB (Phison E12, DRAM-equipped, 3,500/2,700 MB/s) is a meaningful step up in both performance and platform maturity.

## Performance

Rated sequential throughput of 2,500 MB/s read and 2,100 MB/s write represents the Phison E13T platform's maximum. Reads are roughly 4.5x faster than a SATA SSD; writes are about 3.8x faster. For an all-in-one system drive — OS, applications, and a large game library — the 2,500 MB/s read speed ensures Windows boots in under 15 seconds and game levels load in single-digit seconds. The 2,100 MB/s write speed means game installs from Steam complete as fast as gigabit internet allows.

Random 4K performance at 295K/430K IOPS is the E13T's ceiling. The HMB-sourced FTL keeps lightly-threaded random I/O responsive for everyday use. The DRAM-less architecture does show its limits under heavy mixed workloads — simultaneous large file copies, application installs, and background tasks can stress the HMB-based mapping table — but for the single-task usage pattern typical of the budget gaming and home/office market, the S68 1TB performs without obvious bottlenecks.

The 1TB capacity is the transformative feature. Windows and applications occupy roughly 60-80 GB, leaving over 900 GB for games and files — enough for 10-12 large AAA titles. This is the capacity point where the S68 transitions from boot-drive specialist to legitimate all-in-one solution. The large SLC cache means real-world write performance stays in the fast lane, and thermals remain cool even under extended use.

## Endurance, TBW & Warranty

Addlink provides a 5-year limited warranty for the S68 1TB — notably longer than the 3-year warranty common on budget NVMe drives. Endurance is rated at 800 TBW for the 1TB model per Addlink's product announcement, providing roughly 0.44 drive-writes-per-day over the warranty period. The warranty is tied to the original purchaser and does not cover data recovery.

## Pros and Cons

**Pros:**

- 2,500/2,100 MB/s — 4.5x SATA read speed, E13T platform ceiling at 1TB
- 1TB capacity — genuine single-drive solution for OS, apps, and large game library
- Large SLC cache at 1TB — real-world writes rarely exit the fast cache
- 800 TBW endurance — solid for the budget segment
- 5-year warranty — longer than most budget NVMe competitors
- Single-sided M.2 2280 — universal compatibility, cool-running
**Cons:**

- DRAM-less HMB design — latency penalty under heavy mixed workloads
- Phison E13T is 4-channel — cannot match 8-channel Gen3 drives
- 2,500 MB/s read is well below PCIe 3.0 x4 ceiling for DRAM-equipped drives
- Limited brand recognition and availability vs. major manufacturers
- No hardware encryption (TCG Opal / Pyrite)
- S70 offers dramatically better performance for a modest price increase


## Verdict

The Addlink S68 1TB is the capacity play in the ultra-budget NVMe segment. The Phison E13T DRAM-less platform is not a performance leader — 2,500/2,100 MB/s is adequate rather than impressive by PCIe 3.0 standards — but at 1TB with a 5-year warranty and 800 TBW endurance, the S68 delivers exactly what budget buyers at this capacity care about: a full terabyte of NVMe storage with warranty coverage that outlasts most competitors. For a single-drive budget build where maximizing capacity-per-dollar matters more than chasing benchmark numbers, the S68 1TB is a sensible, warrantied choice. For users who can stretch the budget, the S70 1TB (Phison E12, DRAM-equipped, 3,500/2,700 MB/s) is a meaningful step up in both performance and platform maturity.

## Frequently Asked Questions

### Does the Addlink S68 1TB have DRAM cache?

No. The S68 uses the Phison PS5013-E13T, a DRAM-less controller that relies on NVMe Host Memory Buffer (HMB) to borrow system RAM. This keeps costs low but can result in latency increases under heavy mixed read/write workloads.

### Is the S68 1TB faster than the 256GB model?

Yes. The 256GB model is rated at 2,000/1,200 MB/s due to reduced NAND parallelism. The 1TB model achieves the E13T platform's full throughput of 2,500/2,100 MB/s with all four channels running at maximum interleave. The 1TB model also has a much larger SLC cache and higher endurance.

### How does the S68 compare to the S70?

The S68 uses the DRAM-less Phison E13T (4-channel, HMB) at 2,500/2,100 MB/s. The S70 uses the DRAM-equipped Phison E12 (8-channel, dedicated DRAM) at 3,500/2,700 MB/s. The S70 is a significantly faster and more consistent platform. Choose the S68 for maximum capacity-per-dollar; choose the S70 for better performance and mixed-workload consistency.

### What is the endurance (TBW) of the S68 1TB?

The S68 1TB is rated for 800 TBW per Addlink's product announcement — roughly 0.44 drive-writes-per-day over the 5-year warranty. This is solid for a budget 1TB TLC drive.

### Is the S68 1TB good for gaming?

Yes. The 1TB capacity holds Windows plus 10-12 large AAA titles. The 2,500 MB/s read speed ensures fast level loads, and game writes (installs, updates) are typically limited by internet download speed rather than the drive's 2,100 MB/s write ceiling. The 5-year warranty provides peace of mind for a budget gaming build.
