# Biostar M700 1TB — Budget PCIe 3.0 NVMe with Large Capacity (2026)

The Biostar M700 1TB is the largest-capacity variant of Biostar's entry-level PCIe 3.0 NVMe SSD, offering ample storage for budget-conscious builders.

Quick answer: The Biostar M700 1TB is the most practical variant in the M700 lineup, offering enough capacity for a full system build at a budget price. The DRAM-less design, modest speeds, and 3-year warranty place it below mid-range alternatives like the Kingston A2000 and WD Blue SN550. But if you need 1TB of NVMe storage on a tight budget and the M700 is available in your market at a competitive price, it's a functional choice — just don't expect sustained write performance that matches drives costing more.

## Performance

The Biostar M700 1TB is rated at up to 2,000 MB/s sequential reads and 1,650 MB/s writes. These are entry-tier numbers for PCIe 3.0 — the interface can handle roughly 3,500 MB/s, so the M700 uses about 57 percent of the available bandwidth on reads. Compared to the SATA III ceiling of roughly 550 MB/s, the M700's reads are nearly four times faster, which translates to noticeably snappier OS responsiveness and faster game load times.

The DRAM-less HMB design is the primary bottleneck. Testing of the 512GB variant by TechPowerUp revealed a roughly 62 GB SLC cache — once that fills during sustained writes, throughput drops to around 250 MB/s. The 1TB model likely has a larger cache due to its extra NAND capacity, but the pattern will be the same: burst speeds for short transfers, a sharp drop for large file copies. This matters for video editors or anyone moving hundreds of gigabytes at once, but is irrelevant for a boot drive handling typical consumer workloads.

Random read and write IOPS are not officially published for this drive. TechPowerUp's review of the 512GB model noted "very good random read IOPS" for a budget drive, though still behind DRAM-equipped competitors. The M700's real-world performance is adequate for gaming, web browsing, and general productivity, but it cannot compete with mid-range PCIe 3.0 drives like the Kingston A2000 in sustained or stochastic workloads.

## Endurance, TBW & Warranty

The Biostar M700 carries a 3-year warranty, which is standard for budget-tier SSDs but shorter than the 5-year coverage offered by mainstream competitors like the Kingston A2000 and WD Blue SN550. The endurance rating (TBW) for the 1TB variant has not been published by Biostar, consistent with the rest of the M700 lineup. For context, comparable 1TB TLC drives typically carry 400-600 TBW. Without an official number, buyers should treat this as a light-to-moderate use drive. At typical consumer write loads of 20-30 GB per day, a 1TB TLC drive of this class would reasonably last many years, but that's an estimate based on industry norms, not a manufacturer guarantee.

## Pros and Cons

**Pros:**

- 1TB capacity practical for full system builds
- Standard M.2 2280 form factor fits most motherboards
- AES-256 encryption support
- Slim 3.5 mm profile suits compact builds
- Intel 64-layer 3D TLC NAND (not QLC)
- Good thermal performance under normal loads
**Cons:**

- DRAM-less HMB design limits sustained performance
- No published TBW endurance rating
- 3-year warranty shorter than competitors' 5 years
- SLC cache exhaustion drops writes to ~250 MB/s
- Limited independent reviews of the 1TB variant


## Verdict

The Biostar M700 1TB is the most practical variant in the M700 lineup, offering enough capacity for a full system build at a budget price. The DRAM-less design, modest speeds, and 3-year warranty place it below mid-range alternatives like the Kingston A2000 and WD Blue SN550. But if you need 1TB of NVMe storage on a tight budget and the M700 is available in your market at a competitive price, it's a functional choice — just don't expect sustained write performance that matches drives costing more.

## Frequently Asked Questions

### Is the Biostar M700 1TB good for gaming?

The Biostar M700 1TB works well as a budget gaming drive with enough capacity for the OS and a large game library. Its 2,000 MB/s reads are nearly four times faster than SATA SSDs, so game load times will be noticeably quicker than on SATA drives. However, the DRAM-less design means load times won't match faster PCIe 3.0 or PCIe 4.0 alternatives. The 1TB capacity is the most practical size in the M700 lineup for gaming, fitting more titles than the 256GB or 512GB variants.

### Does the Biostar M700 1TB have a DRAM cache?

No, the Biostar M700 1TB is a DRAM-less drive. It uses HMB (Host Memory Buffer), which borrows a small amount of your system's RAM — typically 10-50 MB — to store the flash translation layer mapping table. This keeps the drive's cost down but means random read and write performance is lower than on drives with dedicated DRAM chips. For everyday use the difference is minor, but sustained workloads like large file copies will show the impact.

### What controller does the Biostar M700 1TB use?

The Biostar M700 1TB uses the Silicon Motion SM2263XT controller, paired with Intel 64-layer 3D TLC NAND. This is a DRAM-less NVMe controller designed for budget PCIe 3.0 x4 SSDs. The SM2263XT supports HMB, 3D TLC and QLC NAND, and NVMe 1.3 protocol. It's a well-known entry-level controller that also appears in other budget drives, though specific performance depends heavily on the NAND configuration and firmware tuning.

### What is the TBW endurance of the Biostar M700 1TB?

Biostar has not published an official TBW (terabytes written) endurance rating for any M700 variant, including the 1TB model. This is unusual — even most budget SSDs carry a TBW figure. For context, comparable 1TB TLC drives typically carry around 400-600 TBW. Without an official number, it's impossible to guarantee endurance, though the Intel 64-layer 3D TLC NAND should provide reasonable longevity. At 20-30 GB of writes per day, a 1TB TLC drive could reasonably last many years.

### Does the Biostar M700 need a heatsink?

The Biostar M700 does not ship with a heatsink. Testing of the 512GB variant showed generally good thermal performance under normal loads, though some thermal throttling occurred during sustained heavy workloads. As a PCIe 3.0 entry-level drive with modest speeds, it doesn't generate the heat levels that high-end PCIe 4.0 drives do. At 3.5 mm thickness, it fits under most motherboard M.2 heatsinks. For typical consumer use, passive airflow is sufficient.

### Is the Biostar M700 1TB compatible with PS5?

No, the Biostar M700 1TB 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 M700 is a PCIe 3.0 drive rated at 2,000 MB/s reads, far 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.
