Expert Review Analysis

The ADATA Ultimate SU650 1TB is a budget‑focused 2.5‑inch SATA III SSD that uses 3D NAND flash, offering 520 MB/s sequential reads and 450 MB/s writes, with a 600 TBW endurance rating and a lightweight 47.5 g design.

✓ Best for: Ideal for budget‑conscious PC and laptop upgrades where SATA III is the limiting factor, such as replacing HDDs in older desktops, notebooks without NVMe slots, or as an OS boot drive for faster startups and general storage.✗ Not ideal for: Not suited for heavy video editing, large‑scale data‑center workloads, or any scenario requiring sustained high‑speed writes and low latency, where NVMe or DRAM‑cached SATA SSDs perform better.

Pros

✓High reliability and durability via 3D NAND flash and a 600 TBW endurance rating ensures long‑term data integrity.
✓Solid sequential performance of up to 520 MB/s read and 450 MB/s write stays within the limits of SATA III for fast system boots and file transfers.

4.7

(5,218 reviews)

Lightweight (47.5 g) and compact 2.5‑inch dimensions (100.45 × 69.85 × 7 mm) make installation easy in laptops and desktops.

✓Long MTBF of 2,000,000 hours and robust shock resistance of 1500 G provide strong protection against physical stress.

Cons

✗Limited to SATA III interface, capping maximum throughput around 550 MB/s and lacking the higher speeds of NVMe SSDs.
✗Absence of a DRAM cache; relies on SLC caching which can cause sustained write speeds to drop once the cache is exhausted.
✗Random IOPS performance (40K read / 75K write) is lower than competing SATA SSDs with DRAM, affecting latency‑sensitive workloads.

Expert Opinion

Professional reviewers and editors highlight the SU650 as an excellent cost‑performance option for budget upgrades, emphasizing its 3‑year warranty, 3D NAND durability, and SLC caching that delivers smoother boot‑up and file‑transfer experiences compared to older HDDs.

How It Compares

vs. Crucial MX500 1TB

Advantages

✓Higher sequential read/write speeds (560/510 MB/s) and significantly higher random IOPS (95K/90K) deliver better overall performance.

Disadvantages

✗Lower TBW rating (360 TB) may result in shorter endurance compared to ADATA's 600 TB.

Choose MX500 if raw performance is the priority; choose ADATA for higher endurance and lower price.

vs. Samsung 870 EVO 1TB

Advantages

✓Similar high sequential speeds (560/530 MB/s) with DRAM cache provides consistent performance and reliability.

Disadvantages

✗Typically priced higher than ADATA while offering comparable endurance, making it less cost‑effective for budget upgrades.

Pick Samsung for premium reliability and performance; ADATA is better for cost‑effective upgrades.

vs. WD Blue 3D NAND 1TB

Advantages

✓Competitive sequential speeds (560/530 MB/s) and a 5‑year warranty make it a solid alternative.

Disadvantages

✗Lower TBW (400 TB) and no DRAM cache result in slightly less endurance and slower random IOPS than ADATA.

WD offers a reliable option; ADATA edges with higher endurance while remaining budget‑friendly.
