# Biostar M700 256GB — Entry-Level PCIe 3.0 NVMe SSD (2026)

The Biostar M700 256GB is a no-frills PCIe 3.0 NVMe SSD that targets budget builders who need M.2 storage without the premium price tag.

Quick answer: The Biostar M700 256GB is an entry-level PCIe 3.0 NVMe SSD for buyers on the tightest budgets. It'll boot Windows and load games without complaint, but the DRAM-less design, modest speeds, and 3-year warranty place it below drives like the Kingston A2000 and WD Blue SN550. If the M700 is the cheapest option available in your market, it does the job. If you have alternatives at a similar price, you'll likely find better performance and longer warranties elsewhere.

## Performance

The Biostar M700 256GB is rated at up to 1,850 MB/s sequential reads and 950 MB/s sequential writes — modest numbers even for a PCIe 3.0 drive. These speeds sit well below the PCIe 3.0 x4 interface ceiling of roughly 3,500 MB/s, placing the M700 firmly in the entry-tier bracket. Random read and write IOPS are not officially published for this capacity, which is common for budget drives that don't prioritize stochastic performance.

The DRAM-less HMB design is the primary bottleneck. Without a dedicated memory buffer for the flash translation layer, the M700 depends on system RAM and will show noticeable performance drops during sustained workloads that exhaust the SLC cache. For everyday tasks — booting the OS, launching applications, loading games — the drive is perfectly serviceable. But anyone moving large files or running sustained write workloads will see speeds fall well below the advertised burst figures.

Compared to the SATA III ceiling of roughly 550 MB/s, the M700's 1,850 MB/s reads are a meaningful improvement. Game load times on this drive will be noticeably faster than on SATA SSDs, though not dramatically so — the real-world gap between a 1,850 MB/s PCIe 3.0 drive and a 550 MB/s SATA drive is often just a second or two in most titles. Independent reviews of this specific model are scarce, reflecting its limited market presence.

## 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. The endurance rating (TBW) for the 256GB variant has not been published by Biostar, which is itself a red flag — most manufacturers disclose TBW figures even on entry-level drives. Without an official TBW number, it's difficult to quantify the drive's write endurance over its lifespan. At typical consumer write loads of 20-30 GB per day, a 256GB TLC drive of this class would reasonably be expected to last several years, but that's an estimate, not a guarantee. The lack of published endurance data means buyers should treat this drive as a light-use boot drive rather than a heavy-write workstation disk.

## Pros and Cons

**Pros:**

- Standard M.2 2280 form factor fits most motherboards
- AES-256 encryption support
- Slim 3.5 mm profile suits compact builds
- PCIe 3.0 x4 faster than SATA III drives
- Intel 3D TLC NAND (not QLC)
**Cons:**

- DRAM-less HMB design limits sustained performance
- No published TBW endurance rating
- 3-year warranty shorter than competitors' 5 years
- Limited independent reviews available
- Slower than similarly priced Kingston A2000 and WD Blue SN550


## Verdict

The Biostar M700 256GB is an entry-level PCIe 3.0 NVMe SSD for buyers on the tightest budgets. It'll boot Windows and load games without complaint, but the DRAM-less design, modest speeds, and 3-year warranty place it below drives like the Kingston A2000 and WD Blue SN550. If the M700 is the cheapest option available in your market, it does the job. If you have alternatives at a similar price, you'll likely find better performance and longer warranties elsewhere.

## Frequently Asked Questions

### Is the Biostar M700 256GB good for gaming?

The Biostar M700 256GB works as a budget gaming boot drive, but its 1,850 MB/s reads and DRAM-less design mean load times won't match faster PCIe 3.0 or PCIe 4.0 alternatives. For a single game or two alongside the OS, it's fine. If you're building a dedicated game library drive, consider the 512GB model or look at the Kingston A2000, which offers better sustained performance at a similar price point. The 256GB capacity also fills up quickly with modern game installs.

### Does the Biostar M700 256GB have a DRAM cache?

No, the Biostar M700 256GB 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 will show the impact.

### What controller does the Biostar M700 use?

The Biostar M700 uses the Silicon Motion SM2263XT controller. 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 and firmware implementation.

### What is the TBW endurance of the Biostar M700 256GB?

Biostar has not published an official TBW (terabytes written) endurance rating for the M700 256GB. This is unusual — even most budget SSDs carry a TBW figure. For context, comparable 256GB TLC drives typically carry around 150-170 TBW. Without an official number, it's impossible to guarantee endurance, though the Intel 3D TLC NAND should provide reasonable longevity for light consumer use.

### Does the Biostar M700 need a heatsink?

The Biostar M700 does not ship with a heatsink and doesn't strictly require one. 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 if your board has one. For typical consumer use, passive airflow from your case is sufficient.

### Is the Biostar M700 256GB compatible with PS5?

No, the Biostar M700 256GB 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 1,850 MB/s reads, far below Sony's threshold. Additionally, the 256GB capacity is too small for practical PS5 game storage. For PS5 upgrades, look at PCIe 4.0 drives like the WD Black SN850X or Samsung 980 PRO.
