This article covers 限定 キオクシア 内蔵 SSD 960GB 2.5インチ 7mm SATA EXCERIA SSD-CK960S.

Overview

There's nothing quite as satisfying as swapping out an old mechanical hard drive for a solid-state drive. The KIOXIA EXCERIA SSD-CK960S/R is a 960GB SATA 2.5-inch SSD that aims to make that upgrade affordable and painless. With sequential read speeds up to 555MB/s and writes up to 540MB/s, it hits the ceiling of the SATA 3.0 interface, delivering a noticeable jump in system responsiveness. It uses KIOXIA's own BiCS FLASH 3D NAND memory (made in Japan) and comes with a 3-year warranty. Positioned as an entry-level to mid-range SATA SSD, it's a solid choice for budget-conscious users or anyone wanting to breathe new life into an older machine.

Compatibility Guide

This SSD uses the SATA 3.0 (6Gbps) interface and fits into any standard 2.5-inch drive bay with a 7mm z-height. It's compatible with virtually all desktops and laptops that have a SATA port, including older machines from 2010 onwards. If you're replacing a 9.5mm HDD, you may need a spacer if the drive bay doesn't have adjustable height. Power is supplied via the standard SATA power connector, and power draw is minimal (under 5W), so no PSU upgrade is needed. Note that this is not an NVMe drive—it won't fit an M.2 slot.

Product Info

The KIOXIA EXCERIA SSD-CK960S/R is online retailers exclusive model that launched around 2025 as part of KIOXIA's entry-level EXCERIA line. Its price sits around ¥21,980, making it one of the more affordable 960GB SATA SSDs on the market. The drive uses KIOXIA's in-house controller and 3D NAND (BiCS FLASH) manufactured in Japan, which contributes to its reliability reputation. It also supports the SSD Utility software for drive health monitoring and firmware updates. The warranty is 3 years, though note that the warranty period effectively ends if the SSD Utility reports zero remaining lifetime percentage. This product is best classified as a budget-conscious SATA SSD for users who prioritize cost over peak speed.

Best Use Cases

  • Upgrading an old laptop or desktop from HDD: If your system is still on a mechanical drive, swapping to this SSD will cut boot times from minutes to seconds and make applications feel snappy. It's the single best upgrade for an aging PC. However, if your system has an M.2 NVMe slot, you'll get much higher speeds from an NVMe drive for a small price premium.
  • Adding cheap bulk storage to a desktop PC: If you need extra space for games, media, or backups and your motherboard has spare SATA ports, this 960GB drive offers great value per gigabyte. It doesn't use a PCIe lane, so it won't compete with your graphics card or NVMe drive for bandwidth.
  • Building a quiet, low-power secondary PC: The SSD is silent and draws very little power, making it ideal for HTPCs, media servers, or budget office builds.
  • Users who want Japanese-made NAND and reliable warranty: The 3-year warranty and confidence in domestic manufacturing are strong selling points for those wary of no-name drives.

Things to Consider

The main limitation is the SATA interface. If your workload involves frequent large file transfers, video editing, or the latest AAA games with heavy asset streaming, an NVMe SSD will deliver noticeably better performance. The EXCERIA is also an entry-level drive without DRAM cache, which means random write performance may degrade over time or under sustained loads. Additionally, being online retailers exclusive limits purchasing options and price flexibility. The drive comes unformatted, so first-time users need to initialize it in Disk Management. The warranty condition regarding zero remaining lifetime is unusual—once the lifespan counter hits zero, coverage stops. Finally, if you have an M.2 slot available, spending a bit more on an NVMe drive might future-proof you better.

FAQ

Q: Can I use this in a PS5 or PS4?
A: In a PS4, yes—you can replace the internal drive easily. For PS5, this drive will only work as external USB storage (for PS4 games) since the internal slot requires NVMe.
Q: Do I need any additional cables or brackets?
A: The drive includes only a quick start guide and warranty card. You'll need a SATA data cable (for desktops) and a power cable from your PSU. Some laptops require a mounting bracket if swapping from a larger HDD.
Q: How does it compare to the Crucial BX500 or Samsung 870 EVO?
A: All three are SATA drives with similar performance ceilings. The Crucial BX500 often has slightly higher random IOPS and a longer warranty (5 years), while the 870 EVO has a DRAM cache. The EXCERIA is comparable to the BX500 in raw speed but lacks DRAM, so it may feel slightly slower in heavy multi-tasking scenarios.
