Overview

KIOXIA's EXCERIA PLUS G4 series is a high-end internal SSD that fully supports the PCI Express 5.0 interface. The SSD-CK1.0N5PLG4N model offers 1TB of storage and delivers exceptional sequential read speeds of up to 10,000 MB/s and write speeds up to 7,900 MB/s. It leverages KIOXIA's own BiCS FLASH TLC NAND memory, ensuring reliability backed by a 5-year warranty. This drive is ideal for gamers, content creators, and power users who demand the fastest possible storage performance. Compliant with NVMe 2.0c and using a standard M.2 Type 2280 form factor, this SSD fits seamlessly into modern desktops and compatible laptops. Compared to the previous EXCERIA PLUS G3 generation, it achieves up to 80% better power efficiency, making it not only fast but also power-conscious.

Compatibility Guide

Because the EXCERIA PLUS G4 uses a PCIe Gen5 x4 interface, it requires an M.2 slot with PCIe 5.0 support to reach full speed. It is backward compatible with PCIe 4.0 and 3.0 slots, though maximum transfer rates will be limited accordingly. In a PCIe 4.0 system, you can still expect sequential reads around 7,000 MB/s in most cases. Form factor: M.2 Type 2280 (22mm x 80mm) Interface: NVMe 2.0c / PCIe Gen5.0 x4 Required slot: M.2 M-key (compatible with PCIe Gen5/4/3) Tip: Always verify that your motherboard's M.2 slot supports NVMe in addition to SATA before purchasing.

Product Info

Released around March 2025, this SSD sits firmly in the high-end tier of consumer storage. Its sequential read speed places it among the fastest PCIe 5.0 drives available. As of late August 2026, the 1TB model is priced in the mid-¥30,000 range. It comes with a 5-year limited warranty (ending when the SSD Utility reports zero life). The drive uses KIOXIA's own controller and BiCS FLASH TLC NAND without a dedicated DRAM cache, relying on Host Memory Buffer for efficient operation.

Best Use Cases

Enthusiast Gamers: Modern games benefit from fast storage for level loading and texture streaming. This drive's high sequential speeds reduce wait times noticeably. However, many games may not fully utilize PCIe 5.0 bandwidth, so a PCIe 4.0 SSD could be a more cost-effective choice for gaming only. Video Editors & Creators: Working with 4K/8K RAW footage or large project files is where this SSD shines. The high read/write speeds dramatically improve timeline scrubbing and export times. It's a strong choice for professionals who value every second. * Users Demanding the Absolute Fastest System Drive: If you want the fastest OS and application loading, this SSD is among the best. It competes directly with Samsung 990 Pro and WD SN850X, often matching or exceeding their sequential performance.

Things to Consider

To unleash the full potential of this SSD, you need a motherboard with a PCIe 5.0 M.2 slot. On older platforms, the drive will run at slower speeds, so weigh your upgrade path carefully. PCIe 5.0 SSDs generate significant heat; a heatsink is mandatory. This drive does not include a heatsink, so ensure your motherboard has a built-in M.2 heatsink or purchase an aftermarket cooler. Since it lacks a DRAM cache, heavy random write workloads might see slightly lower performance compared to DRAM-equipped rivals. Finally, check your case's clearance for M.2 drives with thick heatsinks. ## FAQ
Q: Can I use this SSD in a PlayStation 5? A: Yes, physically it fits the PS5 M.2 slot, but the console only supports PCIe 4.0, so speeds will be capped. Adequate cooling is mandatory. KIOXIA does not guarantee operation in external enclosures. Q: What performance can I expect on a PCIe 4.0 motherboard? A: The PCIe 4.0 x4 theoretical ceiling is around 7,000 MB/s. In practice, you'll get between 3,000 and 7,000 MB/s depending on the controller and system configuration. On PCIe 3.0, expect ~3,500 MB/s. Q: Is the warranty affected by usage monitoring? A: Yes. The 5-year warranty expires early if the SSD Utility shows 0% life remaining. Also, using the drive in an external enclosure voids the warranty.
