4.4

(103 reviews)

Low active power consumption of up to 4.3 W helps preserve battery life in portable devices.

✓Host Memory Buffer (HMB) caching delivers acceptable sustained write performance despite being DRAM‑less.

✓Supports TCG Opal self‑encryption for added data security on compatible systems.

Cons

✗DRAM‑less architecture can limit performance under heavy, sustained workloads.
✗Sustained sequential write speeds drop to around 300‑550 MB/s, causing throttling during large file transfers.
✗Real‑world latency may be comparable to older SATA SSDs, reducing responsiveness in intensive tasks.
✗Limited capacity options for the 2230 form factor, with only 1 TB available in the BG5 series.
✗No detailed weight information; may be slightly heavier than competing ultra‑compact SSDs.

From Expert Reviews

Praised by Experts

✓High sequential read speed of 3.5 GB/s is impressive for a 2230‑size SSD, according to Tom's Hardware.
✓Extremely compact single‑chip 1 TB design enables upgrades in ultra‑thin devices, praised by YouTube reviewers.
✓Host Memory Buffer (HMB) provides acceptable sustained write performance despite the lack of DRAM, noted by professional reviewers.

Criticized by Experts

✗DRAM‑less design results in lower performance under heavy, sustained workloads compared to DRAM‑equipped SSDs.
✗Sustained write speeds fall to roughly 300‑550 MB/s, causing noticeable throttling during large transfers.
✗Latency can be similar to older SATA SSDs, making it less suitable for high‑performance computing tasks.

From User Reviews

Users Love

✓Fits perfectly in Steam Deck and Surface devices, providing a reliable upgrade path for thin hardware.
✓Compact size and single‑sided design make installation easy in ultra‑thin laptops.
✓Low power draw helps extend battery life in handhelds and portable notebooks.

Users Complain About

✗Everyday users report sustained write speed throttling during heavy usage scenarios.
✗Some users feel the drive is not suitable for high‑end professional workloads or heavy content creation.
✗Lack of DRAM leads to slower performance in demanding applications, according to consumer feedback.

Expert Opinion

Professional reviewers highlight the BG5's solid sequential performance and ultra‑compact size, noting that the 3.5 GB/s read speed is impressive for a 2230 SSD. However, they also point out the limitations of a DRAM‑less design, especially the drop in sustained write speeds and latency that can approach SATA levels, making it less ideal for intensive workloads.

What Users Say

Consumers appreciate the drive's tiny footprint and low power draw, especially for upgrades in Steam Deck and Surface devices. Recurring complaints focus on throttling during large writes and the perception that the SSD lacks the speed needed for demanding professional tasks.

Common Complaints

Sustained write speed throttling, performance limitations due to the DRAM‑less architecture, and latency comparable to older SATA SSDs.

How It Compares

vs. Kioxia BG6 1TB

Advantages

✓Much higher sequential read/write speeds (6,000/5,300 MB/s) provide top‑tier performance.
✓Higher random IOPS (up to 900K) improves responsiveness under load.
✓Retains the same ultra‑compact 2230 form factor for thin devices.

Disadvantages

✗Generally higher price point and may be less widely available.
✗Still DRAM‑less, so some performance limitations remain.
✗Limited real‑world reviews at the time of writing.

Choose BG6 if you need the fastest possible PCIe 4.0 performance in a 2230 size and can pay a premium; otherwise BG5 offers a more budget‑friendly option.

vs. Sabrent Rocket Q 1TB

Advantages

✓Standard M.2 2280 size fits most desktop and laptop builds where space is not a constraint.
✓Often includes DRAM cache, which can deliver more consistent performance under heavy workloads.
✓Broad compatibility with a wide range of PCIe 4.0 platforms.

Disadvantages

✗Larger 2280 form factor cannot replace the BG5 in ultra‑thin devices like the Steam Deck.
✗Performance specifications are less clearly defined in the source data.
✗May lack the optional TCG Opal encryption option found on the BG5.

Select the Rocket Q for conventional laptops or desktops where size isn’t critical and you prefer a DRAM‑cached drive; opt for the BG5 when you need the smallest possible PCIe 4.0 SSD for ultra‑compact hardware.
