# Gigabyte M30 512GB — Fast PCIe 3.0 NVMe SSD with 5-Year Warranty (2026)

The Gigabyte M30 512GB is a high-performance PCIe 3.0 NVMe SSD that pushes near the interface ceiling with a generous 5-year warranty.

Quick answer: The Gigabyte M30 512GB is a strong mid-range PCIe 3.0 NVMe SSD that saturates the interface with 3,500/3,000 MB/s speeds and backs it with a generous 5-year warranty. The DRAM cache and 3D TLC NAND provide solid endurance and consistent performance. Gigabyte's limited track record in the SSD market is the main caveat — while their motherboard and GPU divisions are well-established, the SSD division is relatively new. If you can find the M30 at a competitive price, it's a compelling alternative to the WD Black SN750 and Kingston KC2500.

## Performance

The Gigabyte M30 512GB is rated at up to 3,500 MB/s sequential reads and 3,000 MB/s writes. At 3,500 MB/s, the drive essentially saturates the PCIe 3.0 x4 interface — this is about as fast as a PCIe 3.0 drive can go. The 3,000 MB/s write speed is equally impressive for a 512GB capacity, indicating a well-configured NAND layout with sufficient parallelism across the controller's channels.

Random read and write IOPS are rated at 308,000 and 332,000 respectively. These are strong numbers that place the M30 in the upper tier of PCIe 3.0 mid-range drives. The presence of a 256MB DDR3L DRAM cache is a key factor — it maintains the flash translation layer in fast memory, reducing latency on random reads and writes. In real-world use, this translates to snappy OS responsiveness, fast application launches, and quick game loading.

The SLC cache behavior is not documented for this drive, but drives in this performance class typically employ a generous dynamic SLC cache that can absorb substantial burst writes. On a 512GB drive, the SLC cache could be 50-100 GB or more depending on free space. This means the M30 will sustain its advertised write speeds for typical consumer workloads, with performance only dropping during very large sustained file transfers. Independent reviews of the M30 are limited, but the advertised speeds and IOPS place it competitively against the WD Black SN750 and Kingston KC2500 in the mid-range segment.

## Endurance, TBW & Warranty

The Gigabyte M30 carries a 5-year warranty — a full two years longer than the 3-year coverage common on budget drives. This matches the warranty terms of mainstream competitors like the WD Black SN750 and Samsung 970 EVO. The endurance rating is 350 TBW on the 512GB model, which is solid for this capacity. For context, the WD Blue SN550 512GB carries 300 TBW, and the Samsung 970 EVO 512GB carries 300 TBW as well. At typical consumer write loads of 20-50 GB per day, the 350 TBW rating equates to roughly 19-48 years of usage before hitting the endurance limit — well beyond the 5-year warranty period. The 1TB model carries 650 TBW, showing that TBW scales appropriately with capacity in this lineup.

## Pros and Cons

**Pros:**

- 3,500 MB/s reads saturates PCIe 3.0 x4 interface
- 256MB DDR3L DRAM cache for consistent performance
- 350 TBW endurance with 5-year warranty
- 3D TLC NAND (more durable than QLC)
- Strong random IOPS (308K read / 332K write)
**Cons:**

- Controller not disclosed by Gigabyte
- Limited SSD track record from Gigabyte
- Scarce independent reviews available
- 512GB capacity limiting for large game libraries
- PCIe 3.0 — outpaced by PCIe 4.0 alternatives


## Verdict

The Gigabyte M30 512GB is a strong mid-range PCIe 3.0 NVMe SSD that saturates the interface with 3,500/3,000 MB/s speeds and backs it with a generous 5-year warranty. The DRAM cache and 3D TLC NAND provide solid endurance and consistent performance. Gigabyte's limited track record in the SSD market is the main caveat — while their motherboard and GPU divisions are well-established, the SSD division is relatively new. If you can find the M30 at a competitive price, it's a compelling alternative to the WD Black SN750 and Kingston KC2500.

## Frequently Asked Questions

### Is the Gigabyte M30 512GB good for gaming?

The Gigabyte M30 512GB is excellent for gaming with 3,500 MB/s reads that deliver fast game load times. The DRAM cache provides consistent random read performance, which matters more for game loading than sequential speeds. The 512GB capacity fits the OS and several modern games, though large game libraries will require management. For a dedicated game library drive, consider the 1TB variant or a PCIe 4.0 alternative.

### Does the Gigabyte M30 512GB have a DRAM cache?

Yes, the Gigabyte M30 512GB includes 256MB of DDR3L DRAM cache. This is a significant advantage over DRAM-less designs like the WD Blue SN550 or Kingston NV2, as a DRAM cache maintains more consistent performance under mixed workloads and improves random I/O responsiveness. The DRAM cache stores the flash translation layer mapping table, reducing latency on random reads and writes.

### What is the TBW endurance of the Gigabyte M30 512GB?

The Gigabyte M30 512GB is rated at 350 TBW (terabytes written) with a 5-year warranty, whichever comes first. This is solid for a 512GB drive — comparable to the Samsung 970 EVO 512GB at 300 TBW and the WD Blue SN550 512GB at 300 TBW. At typical consumer write loads of 20-50 GB per day, the 350 TBW rating equates to roughly 19-48 years of usage before hitting the endurance limit, well beyond the 5-year warranty period.

### What controller does the Gigabyte M30 use?

Gigabyte does not disclose the specific controller used in the M30. This is common for first-party branded drives that source from OEM suppliers. Based on the performance characteristics — 3,500/3,000 MB/s speeds, DRAM cache, and 3D TLC NAND — the M30 likely uses a mid-range Silicon Motion or Phison controller from the PCIe 3.0 era. The undisclosed controller is a minor concern given the strong advertised performance and 5-year warranty.

### Does the Gigabyte M30 need a heatsink?

The Gigabyte M30 does not ship with a heatsink. As a high-performance PCIe 3.0 drive pushing near the interface ceiling, it may generate moderate heat under sustained loads. For typical consumer use, passive airflow from your case is sufficient. If your motherboard includes an M.2 heatsink, the M30 will fit under it at standard single-sided height. For sustained write workloads, a heatsink helps maintain consistent performance by preventing thermal throttling.

### Is the Gigabyte M30 512GB compatible with PS5?

No, the Gigabyte M30 512GB is not suitable for the PS5. Sony requires a PCIe 4.0 NVMe SSD with sequential read speeds of at least 5,500 MB/s for PS5 storage expansion. The M30 is a PCIe 3.0 drive rated at 3,500 MB/s reads, well below Sony's threshold. For PS5 upgrades, look at PCIe 4.0 drives like the WD Black SN850X, Samsung 980 PRO, or Seagate FireCuda 530.
