# Silicon Power US75 4TB Review — Bulk Gen4 Storage, Bare and Simple (2026)

The Silicon Power US75 4TB tops its line with 7,000/6,500 MB/s ratings and 2,400 TBW of endurance — bulk Gen4 storage on an 8-gram bare board.

Quick answer: Buy the Silicon Power US75 4TB when the goal is a large game library or archive volume with real Gen4 speed and no premium: 7,000/6,500 MB/s ratings, 2,400 TBW of endurance, TLC flash and a slim bare board that fits secondary slots with ease. Skip it for professional sustained-write duty — a DRAM-equipped drive such as the WD Black SN850X handles those better — and check the fine print if QLC pricing elsewhere looks tempting, because the endurance gap at 4 TB is enormous. Against the Lexar NM790 4TB it is essentially the same hardware; choose on price and availability. As bulk TLC storage, this is a competent, well-warrantied package.

## Performance

Silicon Power rates the 4 TB US75 at 7,000 MB/s sequential reads and 6,500 MB/s writes, with no official IOPS figure published. Reads remain firmly in the top Gen4 band — the 400 MB/s reduction versus the 1 TB and 2 TB models is invisible in any real workload — while the 6,500 MB/s write rating matches the 2 TB model and moves a 100 GB game in well under two minutes of burst time. As a bulk volume, what matters is how the drive behaves when the SLC cache is gone, and here the 4 TB capacity is at its best: the pseudo-SLC cache spans a large data pool, so mixed workloads rarely exhaust it, and sustained transfers settle to a steady native TLC rate rather than collapsing.

The DRAM-less Host Memory Buffer architecture keeps translation tables in system RAM, and with 4 TB of flash the tables grow — reviewers of the smaller models found the platform's responsiveness solid, and the same firmware scales up. Thermals follow the family pattern: Tom's Hardware and FunkyKit both documented cool, efficient operation without a heatsink, and the 4 TB card's greater package count spreads the same heat further. In a tower with any airflow the bare card is self-sufficient; for a sealed or GPU-adjacent slot, the heatsink SKU adds margin. Independent benchmarks of this exact 4 TB variant remain scarce, so the manufacturer ratings stand as the reference.

## Endurance, TBW & Warranty

Silicon Power covers the US75 4TB with a 5-year limited warranty rated to 2,400 TBW, whichever arrives first — confirmed by TechPowerUp's database entry and Wccftech's coverage of the 4 TB launch. That endurance budget equals about 1.3 TB of writes every day across the full warranty term; even a heavy 200 GB-per-day archive workload would run more than 32 years against the rating, so the 5-year term is the practical limit. The MTBF is rated at 1.5 million hours per Silicon Power's spec sheet — a fleet-level statistic, not a promise for any individual card. Sibling capacities carry 300, 600 and 1,200 TBW. Claims go through Silicon Power's regional support network with proof of purchase, with retailers handling most first-line returns.

## Pros and Cons

**Pros:**

- 2,400 TBW endurance with 5-year warranty
- Full 6,500 MB/s write rating at 4 TB
- Large SLC cache headroom on a 4 TB population
- Slim 8 g single-sided board fits secondary slots
- YMTC 232-layer TLC, not QLC
**Cons:**

- Reads rated below the 1 TB and 2 TB models
- DRAM-less design on the standard card
- No heatsink included on the standard card
- NAND batches can vary between retail units


## Verdict

Buy the Silicon Power US75 4TB when the goal is a large game library or archive volume with real Gen4 speed and no premium: 7,000/6,500 MB/s ratings, 2,400 TBW of endurance, TLC flash and a slim bare board that fits secondary slots with ease. Skip it for professional sustained-write duty — a DRAM-equipped drive such as the WD Black SN850X handles those better — and check the fine print if QLC pricing elsewhere looks tempting, because the endurance gap at 4 TB is enormous. Against the Lexar NM790 4TB it is essentially the same hardware; choose on price and availability. As bulk TLC storage, this is a competent, well-warrantied package.

## Frequently Asked Questions

### Is the Silicon Power US75 4TB good for gaming?

Yes, and 4 TB is the capacity where a Gen4 drive stops being a boot disk and becomes the whole library. The 7,000 MB/s read rating stays in the top PCIe 4.0 band, so load times are indistinguishable from any flagship, and the 6,500 MB/s write rating installs 100 GB-plus titles quickly. The large SLC cache at this capacity keeps burst performance strong through long gaming-session downloads, and the platform runs cool without a heatsink per reviewers' testing of the family. For a PC that hosts dozens of games, or as a PS5-side volume with an added heatsink, it fits the role well.

### Is the Silicon Power US75 4TB compatible with the PS5?

It meets Sony's speed criteria — 7,000 MB/s rated reads clear the 5,500 MB/s recommendation comfortably, and the slim 22.0 x 80.0 x 3.6 mm board fits the console's physical limits — but the standard card ships without a heatsink, which Sony's setup expects. The fix is either an inexpensive aftermarket low-profile cooler or Silicon Power's heatsink-equipped US75 SKU. With cooling addressed, 4 TB is the dream-case console expansion: an entire PlayStation library with years of headroom, and the 2,400 TBW endurance budget dwarfs anything console gaming can generate.

### What is the TBW endurance of the US75 4TB?

The 4 TB model is rated at 2,400 TBW under a 5-year limited warranty, whichever arrives first — confirmed by TechPowerUp's database and Wccftech's launch coverage. That is the largest budget in the US75 line, double the 2 TB model's 1,200 TBW and eight times the 512 GB model's 300 TBW. In practical terms it allows about 1.3 TB of writes per day across five years; even a 200 GB-per-day workload would take over 32 years to exhaust. The TLC NAND behind the figure is the standout advantage over QLC-based 4 TB competitors, whose endurance budgets are typically far smaller.

### Does the Silicon Power US75 4TB have a DRAM cache?

No — the US75 line is DRAM-less across all capacities, including the 4 TB. The Maxio MAP1602 controller uses the NVMe Host Memory Buffer feature to keep flash translation tables in system RAM, and a pseudo-SLC cache carved from the YMTC 232-layer TLC absorbs burst writes. At 4 TB both mechanisms have unusually generous room: the cache spans a large data pool and everyday workloads rarely exhaust it. The DRAM-less design's fingerprints appear only in sustained transfers that outlast the cache, where throughput settles to native TLC rates, and in the value pricing the architecture enables.

### Silicon Power US75 4TB or Crucial P3 Plus 4TB?

The storage type is the whole argument. The P3 Plus uses QLC flash, so its 4 TB endurance budget and sustained-write behavior trail the US75's TLC-based 2,400 TBW rating substantially, and QLC performance degrades further as the drive fills. The US75 counters with 7,000/6,500 MB/s rated speeds, TLC endurance and a 5-year warranty, typically at a modest premium. Both are DRAM-less Gen4 drives that suit bulk storage duty. Choose the P3 Plus only when absolute lowest price per terabyte governs and writes will be rare; for any workload involving regular installs, transfers or editing, the US75's TLC is the safer long-term buy.

### Is the US75 4TB suitable as a video editing archive drive?

As a project and footage archive, yes — 4 TB holds a serious body of 4K material, the 6,500 MB/s write rating ingests camera cards faster than any SD or CFexpress reader can feed it, and the 2,400 TBW endurance budget shrugs off rewrite-heavy editing. As a live scratch disk for multi-camera 6K or 8K timelines, be more careful: the drive is DRAM-less, so cache-exhausting sustained writes settle to native TLC rates, and no independent benchmark of this exact 4 TB variant exists to verify its worst-case behavior. Creators with sustained workloads should look at DRAM-equipped flagships; everyone else gets a capable, well-warrantied volume.
