Lexar EQ790 1TB

Manufacturer: Lexar

The Lexar EQ790 1TB is an M.2 form factor NVMe solid-state drive built around a PCIe 4.0 interface, targeting users who need high-throughput storage in a compact footprint. It operates without an integrated heatsink or RGB lighting, keeping the design straightforward and focused purely on storage performance. One of its standout specifications is a sequential read speed of 7000 MB/s, which places it firmly in the upper tier of PCIe 4.0 consumer drives.

On the technical side, the EQ790 uses HMB (Host Memory Buffer) caching rather than dedicated DRAM, borrowing a portion of system RAM to manage indexing tasks. It carries a 1TB usable capacity, a TBW rating of 600 terabytes, and an MTBF figure of 1.5 million hours, giving a reasonable picture of its rated longevity. The drive conforms to NVMe version 1.4, achieves a PassMark SSD score of 42067, offers shock resistance rated at 1500G, and is backed by a 5-year warranty.

Pros
  • Sequential read speed of 7000 MB/s and sequential write speed of 6000 MB/s indicate strong throughput for large file transfers
  • A TBW rating of 600 teabytes alongside an MTBF of 1.5 million hours points to solid rated endurance for sustained workloads
  • The 5-year warranty provides meaningful long-term coverage
  • Shock resistance rated at 1500G offers reasonable protection against physical impacts
  • The M.2 form factor and absence of a heatsink allow for straightforward installation in space-constrained builds
  • NVMe 1.4 over PCIe 4.0 ensures compatibility with a wide range of modern motherboards
Cons
  • Relies on HMB caching rather than dedicated DRAM, which may affect sustained performance consistency under heavy mixed workloads
  • No integrated heatsink means thermal management depends entirely on the host system
  • Absence of RGB lighting limits visual customization for users who prioritize that in their builds
Who is this for?

This drive is well-suited to users who regularly handle large file transfers or data-intensive workloads, such as video editors, content creators, and developers working with sizeable project files, where the 7000 MB/s sequential read and 6000 MB/s sequential write speeds translate into tangible time savings. Its 600 TBW endurance rating and 5-year warranty also make it a reasonable fit for workstation builds where the drive will see sustained daily use over several years. The M.2 form factor without a heatsink suits systems that already have adequate airflow or motherboard-mounted thermal pads, and the 1500G shock resistance adds a degree of robustness for desktop environments where minor physical stress is a consideration.

Who is this NOT for?

Users who rely on write-intensive server or NAS workloads may find the HMB caching architecture limiting, since the absence of dedicated DRAM can introduce inconsistency under prolonged mixed or random I/O patterns that go beyond typical consumer use. The drive is also a poor match for systems without any supplemental cooling solution, as the lack of an integrated heatsink means thermals depend entirely on the host platform — a concern in compact or poorly ventilated enclosures. Additionally, users building a visually customized system who expect RGB lighting as part of their aesthetic setup will not find that here, since the drive ships with no lighting whatsoever.

Read speed:

sequential read speed 7000 MB/s

The Lexar EQ790 1TB delivers a sequential read speed of 7000 MB/s, reflecting the throughput ceiling it can sustain when reading large, contiguous data streams under optimal conditions.

Write speed:

sequential write speed 6000 MB/s

The Lexar EQ790 1TB is rated for a sequential write speed of 6000 MB/s, representing the sustained throughput it can achieve when writing large blocks of contiguous data under favorable conditions.

Benchmarks:

PassMark result 42067

In the PassMark storage benchmark, the Lexar EQ790 1TB recorded a PassMark SSD score of 42067, providing a standardized reference point for evaluating its overall storage performance across a range of read, write, and mixed workload tests.

The Lexar EQ790 1TB is an M.2 form factor NVMe SSD conforming to NVMe version 1.4 over a PCIe 4.0 interface, with 1000GB of internal storage capacity managed through HMB (Host Memory Buffer) caching in place of dedicated onboard DRAM. It carries a TBW rating of 600 terabytes and an MTBF of 1.5 million hours, alongside a 5-year warranty that together outline its rated durability over time. The drive is built to withstand shock up to 1500G and ships without an integrated heatsink or RGB lighting.

Final Verdict

The Lexar EQ790 1TB brings together a compelling set of specifications for a PCIe 4.0 M.2 NVMe drive, with its 7000 MB/s sequential read speed and a 600 TBW endurance rating backed by a 5-year warranty making it a credible choice for content creators and workstation users who prioritize throughput and long-term reliability. Its reliance on HMB caching and the absence of an integrated heatsink do place some responsibility on the host system to maintain stable conditions, which means it rewards thoughtful system builds more than plug-and-play scenarios. Overall, the Lexar EQ790 1TB is a well-rounded drive for users whose workloads align with its strengths — those who need it will find its specifications purposeful and its durability figures reassuring.
