This article covers Lexar EQ790 SSD 1TB M.2 2280 PCIe Gen4x4 NVMe 1.4 内蔵ソリッドステートドライブ 最大7.

Overview

The Lexar EQ790 SSD 1TB is an M.2 2280 NVMe internal solid-state drive that leverages the PCIe Gen4x4 interface for blazing-fast data transfers. With sequential read speeds up to 7,000MB/s and write speeds up to 6,000MB/s, this drive dramatically reduces game load times and accelerates large file transfers. It employs HMB (Host Memory Buffer) and SLC caching technology to deliver snappy random access performance despite being a DRAM-less design. Officially supported as an expansion storage option for the PlayStation 5, the EQ790 targets a broad audience ranging from PC gamers to creative professionals. It sits comfortably in the mid-high tier of the NVMe SSD market, offering a compelling balance of speed and affordability. A 5-year limited manufacturer warranty provides peace of mind for long-term use.

Compatibility Guide

The Lexar EQ790 uses the M.2 2280 form factor and connects via a PCIe 4.0 x4 interface with NVMe 1.4 protocol. It is backward compatible with PCIe 3.0 slots, though performance will be capped at around 3,500MB/s in that case. Compatible devices include desktop PCs, laptops with an M.2 slot, and the PlayStation 5. On PS5, simply install the drive into the console's M.2 expansion bay and format it through the system menu. Ensure your PS5 firmware is up to date (NVMe 1.4 support is included in recent versions). Form factor: M.2 2280 Interface: PCIe 4.0 x4, NVMe 1.4 Supported OS: Windows, macOS, Linux (including PS5) Power consumption: up to ~5W (low idle draw)

Product Info

The Lexar EQ790 SSD 1TB launched in 2024 and is widely available through major online retailers. At around ¥53,580 on , it offers competitive pricing for a 1TB PCIe 4.0 drive. Positioned in the mid-high tier, this SSD achieves its speed through HMB and SLC caching rather than a dedicated DRAM buffer, keeping costs down while maintaining real-world responsiveness. It uses 3D NAND flash memory for reliable long-term storage. Capacity: 1TB Sequential read: up to 7,000MB/s Sequential write: up to 6,000MB/s Warranty: 5 years limited * Availability: and other major online stores

Best Use Cases

PS5 Owners If you're running out of space on your PlayStation 5, the EQ790 is a straightforward upgrade. It fits directly into the console's M.2 slot and delivers fast load times. However, if you need performance matching the PS5's internal SSD, consider a DRAM-equipped model. PC Gamers Modern games often exceed 100GB, making fast storage essential. The EQ790's high sequential speeds shorten installation and level-loading times significantly. It's especially effective on PCIe 4.0-capable motherboards. Creative Professionals Video editors and photographers handling large files will appreciate the quick transfer speeds. Be aware that sustained heavy writes may cause performance drops compared to DRAM-based drives, so this is better suited for moderate workloads. Laptop Upgraders If your laptop has an M.2 2280 slot, swapping in the EQ790 is a simple way to boost storage capacity and speed. Its low power consumption helps preserve battery life.

Things to Consider

The Lexar EQ790 lacks a dedicated DRAM cache, relying on HMB instead. This means random write performance and sustained write endurance are not on par with DRAM-equipped SSDs like the WD Black SN850X or Samsung 990 Pro. For heavy database or virtualization workloads, those alternatives are better choices. To achieve the full 7,000MB/s read speed, you need a PCIe 4.0-compatible motherboard and CPU. On older PCIe 3.0 systems, performance will be halved. If you're planning a system upgrade, factor in the platform's capabilities. Competitors include Lexar's own NM790 (with DRAM), Crucial P5 Plus, and WD SN770. The EQ790 is a value-oriented pick; if raw speed is your priority, step up to a premium model. ## FAQ
Q: Can I use this SSD with a PlayStation 5? A: Yes, it is compatible with the PS5's M.2 expansion slot. After installation, the console will recognize it as additional storage for games and applications. For performance matching the internal drive, consider a DRAM-based model. Q: Does this drive have DRAM? A: No, it uses HMB (Host Memory Buffer) technology instead, which borrows a portion of system memory as cache. This keeps costs low while still providing good everyday performance. Q: What is the warranty period? A: Lexar offers a 5-year limited warranty. Terms may vary by region and retailer, so check the specific conditions at the time of purchase.
