# Digma Pro Top P6 1 TB: PCIe 5.0 NVMe from an Eastern European brand (2026)

The Digma Pro Top P6 1 TB is a PCIe 5.0 x4 NVMe SSD built on the Phison PS5026-E26 controller with Micron 232-layer B58R TLC NAND and 2 GB LPDDR4 DRAM, rated 11,500 MB/s reads and 700 TBW with a 5-year warranty.

Quick answer: The Digma Pro Top P6 1 TB is a PCIe 5.0 NVMe built on the same Phison PS5026-E26 and Micron 232-layer B58R TLC NAND platform as more widely distributed drives — a capable hardware base. It carries 700 TBW endurance and a 5-year warranty, with rated speeds of 11,500 MB/s reads and 9,500 MB/s writes on the T4 variant.

## Performance

The Digma Pro Top P6 1 TB is rated at 11,500 MB/s sequential reads and 9,500 MB/s sequential writes over PCIe 5.0 x4 — figures for the T4 SKU variant confirmed in Russian retail and technical databases. Random IOPS are rated at 1,300,000 read and 1,500,000 write under 4K QD32 conditions. Note the asymmetry: write IOPS exceed read IOPS, which is consistent with Phison E26 firmware characteristics reported across multiple E26-based drives.

The 11,500/9,500 MB/s speed rating places the Pro Top P6 slightly below comparable E26 drives such as the Crucial T700 (12,400/11,800 MB/s) and reflects the slower-clocked NAND bin used in the T4 variant. The delta is meaningful in sustained sequential transfer benchmarks but less so in everyday workloads — OS operations, game loading, and application reads — where the SLC write cache and random IOPS capabilities are more relevant than peak sequential throughput.

The 1 TB capacity carries a proportionally smaller SLC write cache than a 2 TB variant. Sustained write workloads that exhaust the cache will see throughput fall to direct TLC write rates, as is standard across all TLC NVMe drives at this capacity. Active cooling is required to maintain rated performance under sustained load.

## Endurance, TBW & Warranty

Digma covers the Pro Top P6 with a 5-year warranty — not the 1-year figure that appeared in some database entries. The 1 TB model carries a rated endurance of 700 TBW (terabytes written). Coverage expires at whichever threshold is reached first: five years from purchase, or 700 TBW of cumulative writes.

At a typical write rate of 30 GB per day, exhausting 700 TBW would take approximately 64 years, so the 5-year period will expire first for almost all users. At 100 GB per day the figure is around 19 years. Only users writing 400 GB or more per day on a sustained basis will approach the TBW boundary within the warranty term. Warranty service is handled through Digma's regional support channels, which are concentrated in Russia and the CIS. Buyers outside those regions should confirm local warranty support availability before purchase.

## Pros and Cons

**Pros:**

- Phison PS5026-E26 controller with 2 GB LPDDR4 DRAM cache
- Micron 232-layer B58R TLC NAND — same generation as Crucial T700 and T705
- 11,500 MB/s reads and 9,500 MB/s writes on PCIe 5.0 x4
- 700 TBW endurance rated for the 1 TB model
- 5-year warranty
- 1,500,000 write IOPS rated
**Cons:**

- Write speed (9,500 MB/s) lower than comparable E26 drives such as the Crucial T700 (11,800 MB/s)
- Warranty support concentrated in Russia and CIS — limited coverage elsewhere
- No factory heatsink included — active cooling required and not bundled
- Two SKU variants (T4/T6) with differing speeds — verify before purchase
- Minimal English-language review coverage
- No meaningful performance advantage on PCIe 4.0 platforms


## Verdict

The Digma Pro Top P6 1 TB is a PCIe 5.0 NVMe built on the same Phison PS5026-E26 and Micron 232-layer B58R TLC NAND platform as more widely distributed drives — a capable hardware base. It carries 700 TBW endurance and a 5-year warranty, with rated speeds of 11,500 MB/s reads and 9,500 MB/s writes on the T4 variant.

The primary practical limitation for buyers outside Russia and CIS is warranty support: Digma's service infrastructure is concentrated in Eastern European markets. Within those markets, the Pro Top P6 competes on price against global names using the same E26 hardware.

Buyers in Russia or Eastern Europe seeking a budget PCIe 5.0 option should verify the specific SKU variant (T4 or T6) before purchase, as performance differs between them. Buyers in other regions will typically find better warranty support and similar or better performance from drives like the Crucial T700 or Apacer AS2280F4 at comparable pricing.

## Frequently Asked Questions

### What controller does the Digma Pro Top P6 use?

The Digma Pro Top P6 uses the Phison PS5026-E26 controller, an eight-channel PCIe 5.0 NVMe controller built on TSMC's 12nm process with dual ARM Cortex-R5 cores. This is the same controller used in the Crucial T700, Corsair MP700 Pro, and Seagate FireCuda 540. A database entry listing '4 Channel' refers to the PCIe x4 lane interface, not the NAND channel count — there is no 4-channel variant of the PS5026-E26 in production. The E26 in the Pro Top P6 pairs with 2 GB LPDDR4 DRAM and Micron 232-layer B58R TLC NAND.

### What is the TBW endurance of the Digma Pro Top P6 1 TB?

The Digma Pro Top P6 1 TB carries a rated endurance of 700 TBW (terabytes written). The warranty covers whichever expires first: 5 years from purchase, or 700 TBW of cumulative writes. At 30 GB per day, reaching 700 TBW would take approximately 64 years — the 5-year warranty clock will expire first for virtually all buyers. At 100 GB per day the figure is around 19 years. Only users sustaining 400 GB or more per day of continuous writes will approach the TBW boundary within the warranty term.

### What are the two variants of the Digma Pro Top P6 1 TB?

The Pro Top P6 1 TB is available in two SKU variants distinguished by the suffix in the model number: T4 and T6. The T4 variant (DGPST5001TP6T4) is rated at 11,500 MB/s reads and 9,500 MB/s writes. The T6 variant (DGPST5001TP6T6) is rated at 12,000 MB/s reads and 10,000 MB/s writes. Both use the same Phison PS5026-E26 controller and Micron B58R NAND; the performance difference reflects the NAND clock speed (2400 MT/s vs 1600 MT/s). Verify which variant is being sold before purchasing.

### Does the Digma Pro Top P6 need a heatsink?

Yes, active cooling is required. Digma's product documentation states that the Pro Top P6 requires additional active cooling. The Phison PS5026-E26 controller runs warmer than PCIe 4.0 predecessors due to the higher PCIe 5.0 signalling frequency, and will throttle sustained write throughput if temperatures exceed the controller's thermal threshold. Unlike some competing drives, the Pro Top P6 does not include a factory heatsink — the user must provide motherboard M.2 cooling or a third-party heatsink.

### What warranty does the Digma Pro Top P6 carry?

The Digma Pro Top P6 carries a 5-year warranty — not the 1-year figure appearing in some database entries. The warranty is subject to a 700 TBW endurance limit on the 1 TB model. Warranty service is provided through Digma's regional support channels, which are primarily concentrated in Russia and the CIS. Buyers in other regions should confirm that local warranty service is available before purchasing, as international coverage may be limited compared to globally distributed brands.

### How does the Digma Pro Top P6 compare to the Crucial T700?

Both drives share the same Phison PS5026-E26 controller and Micron 232-layer B58R TLC NAND. The Crucial T700 1 TB is rated at 12,400 MB/s reads and 11,800 MB/s writes, compared to 11,500/9,500 MB/s on the Digma Pro Top P6 T4 variant. The Crucial T700 also carries a global 5-year warranty with established support infrastructure in most markets, while the Digma's warranty support is concentrated in Russia and Eastern Europe. The hardware foundations are similar; the practical differentiation is performance rating, brand availability, and warranty coverage geography.

### Is the Digma Pro Top P6 available outside Russia?

The Digma Pro Top P6 is produced for the Russian and CIS consumer market and is the dominant territory for purchase and warranty service. Limited availability may exist through import channels or cross-border retailers in some Eastern European countries. In North America, Western Europe, and most of Asia-Pacific, the drive is not widely distributed through official retail. Buyers outside Russia should confirm local availability and verify that regional warranty service is accessible before purchasing.

### Does the Digma Pro Top P6 have a DRAM cache?

Yes. The 1 TB Pro Top P6 includes 2 GB of LPDDR4 DRAM paired with the Phison PS5026-E26 controller. The DRAM cache stores the drive's logical-to-physical address mapping table in dedicated on-board memory, providing more consistent random access latency than DRAM-less HMB designs that borrow system RAM via the PCIe bus. The 2 GB capacity is consistent with other E26-based drives at 1 TB.
