4.7

(5 reviews)

Strong random performance with 270K 4K read IOPS and 280K 4K write IOPS, ensuring responsive multitasking and application launches.

✓Robust endurance of 200 TBW and an MTBF of 1.75 million hours, providing long‑term reliability for demanding workloads.

✓Compact M.2 2280 form factor fits easily into thin notebooks and small‑form‑factor PCs without requiring extra space.

Cons

✗Performance is noticeably slower than the 512 GB and 1 TB SN730 variants, which reach up to 3,400 MB/s reads and higher IOPS.
✗Limited 256 GB capacity may be insufficient for users who need large game libraries or extensive media collections.
✗PCIe Gen3 interface caps maximum throughput, making the drive less future‑proof compared to newer Gen4 SSDs.
✗Peak power draw of 1.7 A under load could be a concern for systems with strict power budgets.

From Expert Reviews

Praised by Experts

✓Notebookcheck highlights the SSD’s 3,150 MB/s sequential read and 2,100 MB/s sequential write speeds that fully utilize PCIe Gen3 x4 bandwidth.
✓Professional reviews note the low active power consumption (~100 mW) and ultra‑low sleep power (3.5 mW), which benefit ultrathin and mobile devices.

Criticized by Experts

✗Notebookcheck points out that the 256 GB model’s performance is noticeably slower than the higher‑capacity SN730 variants.
✗Reviewers mention that the PCIe Gen3 interface limits the drive’s longevity as newer Gen4 SSDs become mainstream.

How It Compares

vs. WD Blue SN500 250 GB

Advantages

✓Much higher sequential read (3,150 MB/s vs 1,700 MB/s) and write speeds (2,100 MB/s vs 1,450 MB/s).
✓Significantly better random IOPS performance, delivering smoother multitasking.

Disadvantages

✗Higher power consumption and lack of the ultra‑low 3.5 mW sleep mode found in the SN730.

Choose the SN730 256 GB for superior speed and efficiency; the Blue SN500 is only suitable for budget‑constrained builds with modest performance needs.

vs. WD PC SN730 512 GB

Advantages

✓Higher sequential read/write (3,400 MB/s read, 2,700 MB/s write) and random IOPS (460K read, 400K write) provide noticeably better performance.
✓Increased endurance of 300 TBW offers longer lifespan for heavy write workloads.

Disadvantages

✗Larger capacity may be unnecessary for users who only need a fast boot drive, potentially raising the overall cost.
✗Higher price point compared to the 256 GB model.

Opt for the 512 GB SN730 if you need extra capacity and top‑tier performance; the 256 GB version is ideal for budget‑focused builds where 256 GB is sufficient.
