What Are Obsolete Memory Card Formats and How to Deal with Them

Obsolete Memory Card Formats

With the standardization of SD and microSD, many types of memory cards are basically a thing of the past now. Below are some examples of these old memory card types.

SmartMedia

SmartMedia is an outdated flash memory card standard that was owned by Toshiba. This format was primarily used in the early 2000s for digital cameras and audio production.

SmartMedia memory cards have capacities ranging from 0.5 MB to 128 MB, which is insufficient for today’s storage needs. As a result, this kind of card is no longer produced.

Here are the main features:

• Very thin card used in the late 1990s and early 2000s
• No built-in controller (relied on host device)
• Limited capacity (typically up to 128MB)
• Phased out in the mid-2000s

xD-Picture Card

xD-Picture Card is an obsolete flash memory card format, developed by Olympus and Fujifilm in 2002, replacing SmartMedia. It is primarily used in their digital cameras. xD-Picture Cards are also adopted in some Kodak camera models.

It offers capacities from 16 MB to 2 GB. By the late 2000s, it became less favorable than SD cards due to lower capacity, slower speeds, and higher costs, leading to its phase-out in 2009.

Here are the main features:

• Developed by Olympus & Fujifilm
• Small and compact
• Limited maximum capacity (2GB typical)
• Discontinued as SD became dominant

Memory Stick (Sony)

The Memory Stick is a removable flash memory card format originally launched by Sony in late 1998. It was primarily used in Sony devices like Cyber-shot cameras, Handycams, and PlayStation Portables (PSPs).

It is known for its reliability and portability. It comes in various formats, including Memory Stick Duo, PRO, and Micro (M2). Capacities range from 4 MB in early models to a maximum of 32 GB for the PRO series.

However, like many other items in this post, it becomes unpopular due to compatibility issues.

Here are its main features:

• Proprietary format by Sony
• Used in Sony cameras, camcorders, and PSPs
• Variants: PRO, Duo, Micro (M2)
• Declined as Sony adopted SD

MMC (MultiMediaCard)

The MultiMediaCard (MMC) is a compact, flash-based memory card standard. It was introduced in 1997 for use in portable devices such as cameras and phones.

Its dimensions are 32 × 24 × 1.4 mm. It features a 7-pin serial interface and is often compatible with SD card slots.

Although MMC technology has largely been replaced by faster SD cards, it continues to play an important role through embedded MMC (eMMC) in modern electronics.

Here are key features:

• Predecessor to SD
• Physically similar to SD but less advanced
• Eventually replaced by SD
• Evolved into several variants like SD card, eMMC, RS-MMC (a smaller variant of MMC), etc.

miniSD

miniSD is a smaller version of the standard SD card, which is designed for early mobile phones and cameras.

It supports capacities up to 2GB. For some special 4GB miniSDHC versions, an adapter with standard SD slots is required.

However, the format was largely phased out by 2008 after the introduction of the smaller microSD card.

Here are the key features:

• Smaller than SD, larger than microSD
• Popular in early mobile phones
• Quickly replaced by microSD

CompactFlash

CompactFlash (CF) is a durable and high-performance flash memory card format that was introduced by SanDisk in 1994. It is primarily used in professional photography, videography, and industrial applications.

CF cards provide high-speed, reliable solid-state storage with capacities typically ranging from 32 MB to over 128 GB. They are physically larger than SD cards.

CompactFlash became one of the most successful early memory card formats, surpassing both Miniature Cards and SmartMedia. However, its popularity is declining as CFexpress technology takes over the market.

Key features of CompactFlash:

• Introduced in 1994
• Widely used in early digital cameras and industrial devices
• Larger and more durable than SD
• Replaced by SD and later CFexpress

Other Niche or Vendor-Specific Cards

In addition to the above memory card formats, some other niche or vendor-specific cards are now forgotten by the market. Here are some legacy gaming & personal audio storage cards:

• PlayStation Memory Cards
• Nintendo 64 Controller Pak
• Sega Dreamcast VMU

Further Reading: Why Did Old Memory Card Types Become Obsolete

These memory cards become obsolete due to the following reasons:

• Limited storage capacity
• Slower speeds
• Proprietary restrictions
• Market consolidation around SD/microSD
• Cost and compatibility advantages of SD

Option 2. Erase all Data on It

Some people like to collect early 2000s digital cameras as they think the photos of these old cameras are authentic, raw, and artistic.

However, these older devices may not offer the high capacities of modern memory cards. Therefore, sell your old card to them if you don’t want to keep it.

Before the sale, it’s better to use a tool to erase all your data on it for personal data security. To do that, it is highly recommended to use MiniTool Partition Wizard.
