M.2 2280 vs 2230 SSD Showdown
Form Factor Size
The ADATA SU800 uses the standard M.2 2280 form factor, measuring approximately 3.15 inches in length. This size is common in desktops and most laptops. The Kioxia KBG40ZNS is a compact M.2 2230 drive. It is significantly shorter, designed for small form factor devices like handhelds or thin ultrabooks. If your device has a standard M.2 slot, the ADATA fits easily. If you need to save space or fit a tiny device, the Kioxia 2230 size is the only option. Physical dimensions dictate which drive your motherboard or device can actually accept.
Interface Protocol
The ADATA SU800 connects via the SATA III interface. This protocol has been the standard for years and offers consistent performance for general tasks. The Kioxia KBG40ZNS uses a PCIe NVMe interface. NVMe is designed to bypass the SATA bottleneck, allowing for much faster data transfer rates. NVMe drives communicate directly with the CPU through PCIe lanes. This results in lower latency and higher throughput compared to SATA. If your system supports NVMe, the Kioxia interface is technically superior for speed. If you are limited to SATA ports, the ADATA is the necessary choice.
Transfer Speeds
The ADATA SU800 lists maximum read speeds of 560 MB/s and write speeds of 520 MB/s. These are typical top speeds for SATA SSDs. The Kioxia KBG40ZNS does not list specific read or write speeds in the provided data. However, as a PCIe NVMe drive, it is capable of speeds far exceeding 560 MB/s, often reaching thousands of MB/s depending on the specific PCIe generation. For heavy file transfers or large asset loading, the Kioxia interface allows for significantly higher potential speeds. The ADATA speeds are sufficient for everyday computing but limited by the SATA standard.
NAND Technology
The ADATA SU800 utilizes 3D TLC NAND flash memory. TLC (Triple-Level Cell) stores three bits per cell, balancing capacity and cost. It also employs SLC caching to boost performance during burst writes. The Kioxia KBG40ZNS data does not specify the NAND type or caching method. Without this information, we cannot compare the endurance or sustained write speeds directly. The ADATA provides more transparency regarding its internal memory structure. You know it uses 3D TLC with SLC caching. For the Kioxia, the specific NAND technology remains unknown from the available specifications.
Storage Capacity
The ADATA SU800 is available in multiple capacities, including 128 GB, 256 GB, 1 TB, and 2 TB. The specific model listed is the 256 GB version. The Kioxia KBG40ZNS is listed with 128 GB of storage. The ADATA offers a wider range of options if you need more space. The 256 GB ADATA provides double the storage of the 128 GB Kioxia. If you require more than 128 GB, the ADATA is the better choice. If you only need minimal storage for a specific compact device, the Kioxia capacity may suffice.
Which M.2 SSD fits your needs
Steam Deck or Switch owners
You need the compact M.2 2230 form factor to fit handheld consoles like the Steam Deck or Nintendo Switch. The Kioxia KBG40ZNS is built for these tight spaces. Its PCIe NVMe interface ensures faster data transfer than older SATA drives. This size compatibility is critical for portable gaming devices with limited internal volume.
Desktop or standard laptop users
Your system likely has a standard M.2 2280 slot. The ADATA SU800 fits these common slots in most desktops and laptops. It offers 256GB of storage using SATA III connectivity. The 560 MB/s read speed is sufficient for general computing tasks. This larger drive is the practical choice for standard PC builds.
Users needing SATA compatibility
Some older motherboards or specific slots only support SATA protocols. The ADATA SU800 uses a SATA interface, making it compatible with systems that lack NVMe support. It provides reliable performance with 520 MB/s write speeds. This interface choice ensures you can upgrade storage without worrying about protocol mismatches in your current hardware setup.

Frequently asked questions
Can I use an M.2 2280 SSD in a slot designed for M.2 2230?
No, you cannot fit a larger drive into a smaller slot. The M.2 2280 form factor measures approximately 3.15 inches in length, while the M.2 2230 is significantly shorter. Your motherboard or device must have the specific physical keying and mounting holes for the drive you choose. Using the wrong size will prevent installation.
Does M.2 2230 always mean NVMe connectivity?
Not necessarily, but most modern compact drives use NVMe. The Kioxia KBG40ZNS is an M.2 2230 drive that uses the NVMe interface for high-speed data transfer. However, M.2 slots can also support SATA protocols. You must check your device specifications to confirm whether it supports NVMe or requires SATA for that specific form factor.
Is the ADATA SU800 an NVMe drive?
No, the ADATA SU800 uses the SATA III interface. It is an M.2 2280 drive that connects via the older SATA protocol. This means it offers sequential speeds typical of SATA SSDs rather than the higher speeds of NVMe drives. It is a practical choice for systems that support SATA M.2 connections but do not require PCIe speeds.
What NAND type does the ADATA SU800 use?
The ADATA SU800 uses 3D NAND with TLC (Triple-Level Cell) technology. This configuration allows for higher storage densities and improved endurance compared to older planar NAND. It provides solid sequential speeds and data protection features for users who prioritize reliability and capacity over the absolute fastest read and write speeds found in premium NVMe models.
Which drive is better for a Steam Deck?
The Kioxia KBG40ZNS is the better choice for a Steam Deck. Handheld consoles require the compact M.2 2230 form factor to fit within their tight internal spaces. The ADATA SU800 is too large for these devices. The Kioxia drive also uses the NVMe interface, ensuring fast load times for games in a small package.
Can I use M.2 2230 drives in standard laptops?
Only if your laptop specifically supports the 2230 form factor. Most standard laptops and desktops use the larger M.2 2280 size. The Kioxia KBG40ZNS is designed for compact handheld PC builds and devices with limited space. You must verify your motherboard or chassis specifications to ensure it has the correct mounting points and slot length for a 2230 drive.
