What’s the best Steam Deck SSD? This post collects a list of best SSDs for Steam Deck in 2024.

SABRENT Rocket 2230 NVMe SSD (1TB)

Being one of the best SSDs for Steam Deck, SABRENT Rocket 2230 NVMe SSD has one of the fastest speeds and a high 600 TBW endurance. Besides, it has a 176-layer Micron TLC NAND and comes with capacities ranging from 256GB to 1GB.

With a PCIe Gen4 interface, SABRENT Rocket 2230 boasts high read and write speeds. To be specific, the drive is capable of reaching up to 5Gbps and 800K IOPS. It is also worth noting that the SSD is backward compatible with Gen3 and Gen2 PCIe slots.

In addition to Steam Deck, SABRENT Rocket 2230 is also compatible with devices like Microsoft Surface, smaller HTPC, and other devices with limited space inside them. Moreover, it also works on a few longer slots. So, perform a compatibility check before you buy the SSD.

The SSD is DRAM-less and has high-density 3D TLC, which aims to keep the drive cool. For any questions related to manufacturing, you can contact its manufacturer because it offers a 5-year warranty.

WD Black SN770M delivers the best performance thanks to the combination of a fast controller (M.2 2230 form factor), high-speed BiCS5 NAND Flash, and efficient firmware. To be specific, it delivers sequential reads/writes speeds up to 5,150/4,900MB/s.

The SN770M is not only a shorter version of the SN770 but also a retail version of the WD SN740. A retail warranty with full WD support is a welcome bonus. However, this drive pays a price for its capacity and performance.

The warranty of WD Black SN770M is 5 years.

The TLC Flash of this best SSD for Steam Deck scales from 500GB to 2TB capacity. Please note that getting large capacity NAND Flash and fast controller is pretty challenging at 2230. Besides, this drive runs a bit hotter under load and can consume comparatively large amounts of power.

INLAND TN446 2230 SSD (1TB)

Designed for users who have a limited budget but don’t want to sacrifice speeds, the INLAND TB446 SSD is regarded as the best Steam Deck SSD in terms of budget. It offers speeds that are comparable to Sabrent Rocket and WD_Black but at two-thirds of the cost.

It has the same endurance as the other two entries but has a 6-year warranty. Its endurance is 600 TBW for 1TB. With TLC NAND Flash, it has high performance. The drawback of this SSD is that it has limited availability because it’s a Micro Center Brand.

XPC X740 M.2 NVMe PCIe SSD (1TB)

Though XPC is not very famous in the industry, it beats the likes of Sabrent. XPC X740 delivers read/write speeds up to 5,100/4,800MB/s. As XPC X740 is single-sided, it is fully compatible with Steam Deck.

Besides, this Gen4 SSD has TLC NAND, but its endurance is rated at 400 TBW. That’s the compromise you need to make at these prices. Even so, it is still one of the best SSDs for Steam Deck in 2024.

Corsair MP600 Mini M.2 NVMe 2230 SSD (1TB)

Corsair MP600 Mini is a high-density SSD for Steam Deck. It delivers read/write speeds of 4,800/4,800MB/s, which is more than snappy enough for Steam Deck. Its random performance at up to 850K IOPS for reads and 1.1M IOPS for writes is better enough, offering some especially snappy load times to access games faster.

Given that fact, the MP600 Mini will be limited by Gen 3 speeds, but it’s faster than the internal drive in the Steam Deck, and is ten times faster than the sluggish 64GB of eMMC storage in the base model.

The MP600 Mini has the same 600 TBW endurance as higher-priced SSDs and the same 5-year warranty. The NAND is TLC, which is better than QLC. As for capacity options, the MP600 Mini is only available in 1TB.

This post summarizes the difference between QLC and TLC, helping you make a wise choice.

Micron 2400 (2TB)

Micron 2400 is one of the best Steam Deck SSDs in large capacity. The 2400 offers faster storage than either the Steam Deck’s built-in SSD or eMMC storage, which runs at the speed of 2,500MB/s or 300MB/s respectively. If this drive is hooked up to a PCIe 4.0 port, it can read up to 4,200MB/s.

Though you may see 3,500MB/s if the Steam Deck is limited to PCIe 3.0 speeds, this is a significant upgrade to the original storage.

Fanxiang S700 (1TB)

Fanxiang S700 is the latest addition to the “best SSD for Steam Deck” list. It is another M.2 2230 option that’s ideal for slotting into Steam Deck, or Steam Deck OLED. Its read and write speed can reach up to 5,000MB/s and 4,600MB/s, making it one of the quickest drives. It comes in 500GB and 1TB capacities.
