# Goodram IRDM Ultimate 120GB — Compact PCIe 3.0 NVMe SSD (2026)

The Goodram IRDM Ultimate 120GB is a compact PCIe 3.0 NVMe drive built on the Phison E7 controller with Toshiba MLC NAND, offering strong sequential performance and a 5-year warranty in an OEM-capacity form factor.

Quick answer: The Goodram IRDM Ultimate 120GB is a competent PCIe 3.0 NVMe boot drive with a 5-year warranty and MLC NAND durability. Its main limitation is the 120GB capacity, which is tight for modern use. It makes sense as a dedicated boot drive for users who pair it with a larger secondary drive. For users who need more capacity, the IRDM Ultimate 240GB or 480GB offer the same platform with more usable space.

## Specifications

| Specification | Value |
| --- | --- |
| Capacity | 120 GB |
| Interface | PCIe 3.0 x 4 |
| Controller | Phison PS5007-E7 |
| Memory type | Toshiba MLC |
| DRAM cache | Nanya 256 - 512 DDR3L |
| Sequential read | 2900 MB/s |
| Sequential write | 2200 MB/s |
| Random read IOPS | 235000 |
| Random write IOPS | 270000 |
| Endurance | 279 TBW |
| MTBF | 2 |
| Warranty | 5 years |

## Performance

Goodram rates the IRDM Ultimate 120GB at up to 2,900 MB/s sequential reads and 2,200 MB/s sequential writes, with random performance up to 235,000 read IOPS and 270,000 write IOPS. These are strong numbers for a Phison E7-based drive, with write performance in particular benefiting from the MLC NAND's faster program times compared to TLC.

The Phison E7 controller was one of the first consumer NVMe controllers and has been extensively validated across dozens of brands. It uses a dynamic SLC cache to absorb burst writes, and the MLC NAND provides more consistent sustained-write performance than TLC alternatives. The DRAM cache ensures low-latency random reads.

At 120GB, the drive has limited capacity for modern applications and games. It works best as a dedicated boot drive paired with a larger secondary drive. The E7 controller supports L1.2 low-power mode for laptop use, and the drive's power consumption is modest.

## Endurance, TBW & Warranty

Goodram backs the IRDM Ultimate 120GB with a 5-year limited warranty. The drive is rated for 2 million hours MTBF. The 5-year warranty is a significant advantage over budget drives with 3-year coverage and matches the best in the industry. Goodram does not publish a TBW endurance rating for the IRDM Ultimate series, but the MLC NAND provides inherently higher endurance than TLC alternatives.

## Pros and Cons

**Pros:**

- Phison E7 controller with Toshiba MLC NAND
- 5-year warranty
- 2,900/2,200 MB/s sequential performance
- Nanya DDR3L DRAM cache
- AES-256 encryption and end-to-end data protection
**Cons:**

- 120GB capacity is very limiting
- PCIe 3.0 — slower than PCIe 4.0 alternatives
- No published TBW endurance rating
- Limited regional availability


## Verdict

The Goodram IRDM Ultimate 120GB is a competent PCIe 3.0 NVMe boot drive with a 5-year warranty and MLC NAND durability. Its main limitation is the 120GB capacity, which is tight for modern use. It makes sense as a dedicated boot drive for users who pair it with a larger secondary drive. For users who need more capacity, the IRDM Ultimate 240GB or 480GB offer the same platform with more usable space.

## Frequently Asked Questions

### Does the Goodram IRDM Ultimate 120GB have DRAM?

Yes. The IRDM Ultimate 120GB includes a Nanya DDR3L DRAM cache. This dedicated cache stores the FTL mapping table, providing consistent random I/O performance and reducing write amplification.

### Is the Goodram IRDM Ultimate 120GB good for gaming?

The 120GB capacity is too small for a modern game library — it holds only 2 to 4 AAA titles. It works as a boot drive paired with a larger game storage drive. The 2,900 MB/s read speed is fast for OS and application loading.

### What is the difference between IRDM Ultimate and IRDM Ultimate X?

The IRDM Ultimate is a PCIe 3.0 drive with the Phison E7 controller and Toshiba MLC NAND. The IRDM Ultimate X is a PCIe 4.0 drive with the Phison E16 controller and Toshiba 3D TLC NAND, offering up to 5,000 MB/s reads. They are different platforms targeting different interfaces and performance tiers.

### How does the IRDM Ultimate 120GB compare to the Samsung 960 EVO 128GB?

Both are first-generation PCIe 3.0 NVMe drives from the same era. The IRDM Ultimate uses MLC NAND and offers a 5-year warranty, while the Samsung 960 EVO uses TLC with a 3-year warranty. The Samsung has better brand recognition and software support. The IRDM Ultimate's MLC NAND and longer warranty are advantages.

### What is the TBW endurance of the IRDM Ultimate 120GB?

Goodram does not publish a TBW endurance rating for the IRDM Ultimate series. The drive is backed by a 5-year warranty. The use of MLC NAND provides inherently higher endurance than TLC-based alternatives.
