# Gigabyte Aorus Gen4 2TB: high endurance, real heatsink (2026)

The Gigabyte Aorus Gen4 2TB pairs a DRAM cache and full copper heatsink with an exceptionally high 3,600 TBW rating, even though its Phison E16 controller now trails newer Gen4 flagships on peak speed.

Quick answer: The Gigabyte Aorus Gen4 2TB suits desktop builders who want a DRAM-equipped drive with genuinely exceptional endurance and don't need the absolute fastest Gen4 numbers available today. It's a weaker choice for laptop or PS5 buyers, where the included copper heatsink adds height that may not fit, and for anyone chasing peak sequential speed, where newer Gen4 or Gen5 drives pull well ahead. Buyers who want more speed from a similar-generation DRAM-equipped drive should look at the Samsung 980 Pro or WD Black SN850. Overall, the Aorus Gen4 2TB is a strong pick specifically for its endurance and thermal design, at the cost of trailing current flagships on raw speed.

## Performance

Gigabyte rates the Aorus Gen4 2TB at up to 5,000 MB/s sequential reads and 4,400 MB/s sequential writes over PCIe 4.0 x4, with 750,000 random read IOPS and 700,000 random write IOPS. The Phison E16 is Phison's first-generation PCIe 4.0 controller, now several years old, so these numbers trail current Gen4 flagships that reach 7,000 MB/s or more.

What the Aorus Gen4 still delivers is consistency: the onboard 2 GB DRAM cache keeps mapping-table lookups fast and helps sustained performance hold up better under heavy multitasking than DRAM-less rivals, while the included copper heatsink manages thermals well under extended load without throttling. For gaming, general desktop use, and moderate content work, the real-world difference against faster newer drives is smaller than the spec sheet gap suggests, since most everyday tasks don't saturate a Gen4 x4 link's full bandwidth anyway, and the drive rarely runs into thermal throttling thanks to its included heatsink, even under sustained desktop workloads.

## Endurance, TBW & Warranty

Gigabyte rates the Aorus Gen4 2TB at 3,600 TBW of total write endurance, backed by a 5-year warranty, whichever limit is reached first. At a typical 20-50 GB of writes per day, that endurance budget lasts roughly 197 to 493 years before hitting the rated limit - an exceptionally generous figure even by SSD standards, and notably higher than many same-era competitors. The MTBF rating is 1.8 million hours, a statistical reliability figure describing failure rates across a large population of drives rather than a promise for any individual unit.

For buyers who prioritize long-term endurance headroom over outright peak speed, the Aorus Gen4's TBW rating is one of the strongest in its price and generation.

## Pros and Cons

**Pros:**

- 3,600 TBW endurance, exceptionally high for 2TB
- 2GB DDR4 DRAM cache for consistent performance
- Included full copper heatsink with dual-sided thermal pads
- 5-year warranty
- 750,000 read IOPS
**Cons:**

- 5,000/4,400 MB/s trails newer Gen4 flagships
- Heatsink adds height, may not fit thin laptops or PS5
- Similarly-named 'Aorus Gen4 7000s' is a different, faster drive
- Phison E16 is an older-generation Gen4 controller


## Verdict

The Gigabyte Aorus Gen4 2TB suits desktop builders who want a DRAM-equipped drive with genuinely exceptional endurance and don't need the absolute fastest Gen4 numbers available today. It's a weaker choice for laptop or PS5 buyers, where the included copper heatsink adds height that may not fit, and for anyone chasing peak sequential speed, where newer Gen4 or Gen5 drives pull well ahead. Buyers who want more speed from a similar-generation DRAM-equipped drive should look at the Samsung 980 Pro or WD Black SN850.

## Frequently Asked Questions

### Is the Gigabyte Aorus Gen4 2TB good for gaming?

Yes for most gaming use - its DRAM cache keeps performance consistent under multitasking, and 5,000 MB/s comfortably outruns SATA and most PCIe 3.0 drives for load times. It won't match newer 7,000 MB/s-class Gen4 drives on paper, but the practical difference in game load times is small for most players.

### Is the Gigabyte Aorus Gen4 2TB compatible with the PS5?

Its 5,000 MB/s rated sequential read falls just short of Sony's suggested 5,500 MB/s minimum, and the bigger issue is the included copper heatsink, which adds height that may not fit the PS5's internal M.2 slot without removal. Buyers specifically targeting a PS5 upgrade should check clearance carefully or consider a drive designed without a tall heatsink.

### Does the Gigabyte Aorus Gen4 2TB have a DRAM cache?

Yes, it includes 2 GB of DDR4 DRAM, which helps keep the mapping table fast and sustains more consistent performance under heavy multitasking than DRAM-less budget rivals. This is a genuine advantage over many similarly-priced drives that skip DRAM entirely to cut costs.

### What is the TBW endurance of the Gigabyte Aorus Gen4 2TB?

Gigabyte rates the 2TB Aorus Gen4 at 3,600 TBW (terabytes written), backed by a 5-year warranty, whichever comes first. At a typical 20-50 GB of writes per day, that works out to roughly 197 to 493 years before reaching the rated limit, an exceptionally high figure that makes endurance essentially a non-issue.

### Does the Gigabyte Aorus Gen4 2TB need a heatsink?

No - it already ships with a full copper heatsink and thermal pads on both sides of the PCB, which is more thermal protection than most drives in its class include. This is a plus for desktop sustained loads but does mean the drive is taller than bare M.2 sticks, which matters for laptop or console compatibility.

### How does the Gigabyte Aorus Gen4 2TB compare to the Aorus Gen4 7000s?

Despite the similar name, the 7000s is a different, newer drive built on a faster Phison E18 controller reaching 7,000 MB/s, but with a lower 1,400 TBW rating on its 2TB model versus this drive's 3,600 TBW. Buyers prioritizing peak speed should look at the 7000s, while buyers prioritizing endurance headroom for heavy, long-term writing are better served by this original Aorus Gen4.

### How does the Gigabyte Aorus Gen4 2TB compare to the Samsung 980 Pro?

Both are DRAM-equipped, same-generation Phison E16-class or comparable Gen4 flagships with similar rated sequential speeds, but the Aorus Gen4's 3,600 TBW endurance rating is notably higher than the 980 Pro's typical rating for the same capacity. The Samsung carries a longer independent review track record and broader retail availability.
