SanDisk has produced a number of flash memory-based portable media players from 2005. SanDisk players were marketed under the Sansa name until 2014, then SanDisk Clip.

Model history

Sansa e100

The Sansa e100 series has a monochrome display with a blue backlight, FM tuner with 20 presets, SRS WOW technology, an SD card slot supporting cards up to 2 GB, an internal memory of 512 MB (e130) or 1 GB (e140), and a single AAA battery for power. It supports MP3, WMA and Audible file formats. The e140 was also known as the SDMX2. Released on January 12, 2006, it came in blue or grey, depending on the model.

SanDisk SDMX1 The SanDisk SDMX1 series (including the SDMX1-1024, −512, and −256—reflecting capacity in MB), also known as the SanDisk Digital Audio Player, is a low-end solid state memory MP3 player. It was SanDisk's first personal media player, and the only one of its time not to be sold under the Sansa brand. It supports MP3, WMA, and DRM-protected WMA files. It cannot play seamlessly, and imposes a non-configurable fade at the beginning and end of each file. There is a built-in microphone for low-fidelity (8 kHz) voice recording and an FM radio. The SanDisk SDMX1 is powered by a single AAA battery for around 15 hours of continuous playback. It measures 75.2 mm x 32.8 mm x 20.8 mm and weighs under . Its release date was January 11, 2006.

Sansa m200

The Sansa m200 series was released in four models: m230 (512MB), m240 (1 GB), m250 (2 GB), and m260 (4 GB). It has a built-in FM tuner and microphone, and supports MP3, WMA, WAV, and Audible (.aa) audio file formats. It comes in different colors (one for each memory size) such as blue, black, pink, and grey, and uses a single AAA battery for power. There were four different hardware revisions of this player. The first three revisions used a Telechips TCC770 SoC for a CPU and DSP, and the fourth used a chip developed by Austria Microsystems that was also used in the Clip, Fuze, and later e200/c200 models.

Sansa c100 The Sansa c100-series players have colour displays and are able to show cover art and small picture thumbnails. They use AAA batteries and are available in 1 GB (c140) or 2 GB (c150) of capacity. Microphone and radio capabilities are included.

Sansa e200

The Sansa e200 series was released on January 5, 2006. It includes a video player, FM tuner/recorder, voice recorder with built-in microphone, and picture viewer. The players were available in capacities of 2 GB (e250), 4 GB (e260), 6 GB (e270), and 8 GB (e280). There is also a microSD slot for up to 2 GB of memory expansion. (Larger capacity microSDHC cards up to 32 GB are not supported by the original version 1 firmware, but can be used with alternative Rockbox firmware or on version 2 models.)

The Sansa e200R was released in October 2006. Physically identical to the regular e200, it was sold exclusively at Best Buy or directly through Rhapsody. The player has a feature called Rhapsody Channels, which is the online service's brand of podcasting, and also comes with preloaded content. The Rhapsody firmware also added support for AAC audio files. A regular e200 could be flashed into an e200R and back again.

Sansa TakeTV Released on October 26, 2007, the Sansa TakeTV is a plug-and-play storage device that allows the playback of DivX, Xvid, and MP4 files on an external display via the included dock and remote. Unlike other Sansa products, the TakeTV is not a digital audio player. The device comes in 4 and 8 GB sizes. While the user is free to play their own videos, the TakeTV came with FanFare, a program similar to iTunes that allowed the user to purchase premium content. On December 11, NBCUniversal partnered with SanDisk to provide content on FanFare after having left Apple in a similar deal. The TakeTV and FanFare were discontinued on May 15, 2008.

Sansa View The original Sansa View was SanDisk's attempt at a portable media player, with a 4-inch screen, built-in speaker and an expansion slot for SDHC and SD cards. It was announced on the 2007 Consumer Electronics Show. On June 1, 2007, SanDisk announced that the player had been shelved. It had a redesign, and was launched on October 2007.

Sansa Connect The Sansa Connect is a Wi-Fi-enabled player that allows the user to connect to any open network in the area. The Mono/Linux-based device has a 2.2-inch TFT LCD screen, but unlike SanDisk's previous player, the e200 series, the Sansa Connect does not have the ability to connect via USB mass storage or tune to FM radio. The player was developed by ZING Systems in collaboration with SanDisk and Yahoo!, which provides music streaming via LAUNCHcast radio and a subscription download service. Viewing pictures from Flickr is also possible with the device. The Sansa Connect was only available in the United States with a capacity of 4 GB. Storage can be increased with microSD cards, giving the player up to an extra 2 GB of storage. At the 2007 Consumer Electronics Show, the Sansa Connect won the Best of Show award. A firmware update allows the player to support microSDHC cards for a capacity of up to 8 GB and the playback of digital video.

Sansa c200

The Sansa c200 series has a removable, lithium-ion rechargeable battery, FM tuner/recorder, built-in microphone, 1.4-inch 132x80-pixel colour display, and a microSD card slot. The c200 is compatible with many accessories made for the e200. The c200 is available in 1 GB (c240) and 2 GB (c250) capacities. Later models, referred to as v2, have different hardware that adds support for the Audible file format. The packaging of the new models has been updated with the line "Supports Audible audio file formats". The free Rockbox firmware includes a number of additional features, including support for microSDHC (even on v1 c200s) for up to 32 GB of storage.

Sansa Express The Sansa Express was sold in capacities of 1 GB and 2 GB. It has a built-in USB connector and a 1.1-inch, duochromatic OLED display, a microSD slot, an FM tuner, a microphone for voice recording, an internal lithium-ion battery, and a lanyard to wear the device around one's neck. It is also able to record FM radio and voice on its internal memory. The Express is not considered a descendant of the c200 series, as it only plays audio. It is more similar to the m200 and maintains much of its design and internal software structure. It is the world's first known flash-based digital audio player that does not require a cable for data transfer, though a USB cable is included in the package if needed.

Sansa Shaker

The Sansa Shaker, released in 2007, is a screenless digital audio player with an SD card slot and was sold in blue, red, white, and pink. One 512 MB or 1 GB card is included, and cards up to 4 GB (non-SDHC) can be used. The Shaker's tubular design, resembling that of a salt shaker, is intended to be child-friendly, and it will randomly skip one, two or three songs when shaken. The Shaker plays up to 10 hours of continuous audio with a AAA battery, and has two headphone jacks and a built-in speaker. The upper controller band adjusts volume and the lower controller band skips songs, or fast forwards or rewinds the current song when held. Unlike with other players, the only supported audio file format is MP3. When the memory card is removed during playback, the player emits an "uh-oh" sound. When the player's memory card is put back in, it emits a popping sound.

Sansa Clip

Also known as the m300, the Sansa Clip was released on October 9, 2007. The player is similar in size to the second-generation iPod Shuffle, but incorporates a removable clip and 4-line OLED screen (with one yellow line and three blue lines). The Clip has an FM tuner/recorder and a built-in microphone. The Clip shipped in capacities of 1 GB (available only in black), 2 GB (available in black, blue, red and pink), and 4 GB (silver and black). In November 2008, black and silver 8 GB versions were advertised in the UK.

Midway through production of the Clip, SanDisk updated to a new hardware design, referred to as v2, based on an updated Austriamicrosystems SoC. The updated design moderately improved battery life by introducing a more efficient ARM9E processor in place of the previous ARM9 core. Aside from requiring different firmware upgrades, there were no functional changes to the software. The updated SoC would, however, form the basis for the Clip+ and Clip Zip products. Additionally, the v2 hardware has significantly improved battery life when using the Rockbox firmware (see below) due to dynamic frequency and voltage scaling.

Firmware version 01.01.29, released in May 2008, enabled Ogg Vorbis compatibility for the Sansa Clip. The 01.01.30 firmware update improved OGG support and added FLAC support. The latest firmware packages for the Sansa Clip are 01.01.35 and 02.01.35, which depend on the hardware revision. The official firmware cannot play Ogg Opus files, but support for the opus audio codec is available in Rockbox, a third-party firmware replacement. Rockbox was first released for the Clip v1 on November 21, 2009, and then for the Clip v2 on May 14, 2010.

The device (firmware 01.32+) has five folders: Audible (for Audible content), Audiobooks (for audiobooks that can be "bookmarked" with a resume playback feature), Music, Podcasts (which also support the resume playback feature), and Record (for WAV recordings using the device).

Sansa Fuze

The Sansa Fuze, released on March 28, 2008 in capacities of 2, 4 and 8 GB, is a portable media player with a 1.9-inch color display and a thickness of . It also features a 40-preset FM radio with FM recording, a voice recorder, and a 24-hour battery life on continuous audio playback. Storage is expandable via a microSDHC slot. Firmware version 1.01.22 enables FLAC and Ogg Vorbis playback. Like the Clip, the Fuze underwent two hardware revisions, the first based on the AS3525 (like the first Clip) and the second based on the AS3525+ (like the Clipv2, Clip+ and Clip Zip). The latest firmware releases, depending on hardware version, are 01.02.31, 02.03.31 and 02.03.33.

Sansa Clip+

On August 31, 2009, SanDisk released a redesign of the Sansa Clip called the Clip+, cosmetically similar to the Clip and maintaining its basic design, audio hardware, compatibility, and 4-line OLED screen, but with a few significant differences.

There are 2 GB (black), 4 GB (black, red, blue, white or indigo) and 8 GB (black) models. The case has been redesigned to look more square (including the navigation pad, which is also no longer backlit) and is constructed of higher-quality plastic, the clip is no longer removable, and the player now supports folder browsing and ReplayGain support. Transition times between tracks were reduced, but SanDisk officially declined to support gapless playback. A microSDHC card slot has been added, allowing the storage capacity of the device to be expanded by up to an additional 32 GB. The Clip+ also has added features when playing slotMusic and slotRadio. To make room for the microSDHC slot, there have been some changes from the old Clip, including moving the volume switch to the left side of the device and changing the power/hold switch to a simple power button. Hold mode is now activated by holding the "Home" button on the device. Like previous Clip and Fuze products, the Clip+ retained a directly coupled headphone amplifier, allowing for highly accurate reproduction of bass frequencies and very low distortion on difficult-to-drive headphones.

The Sansa Clip+ proved popular with audio enthusiasts and programmers because of its very low cost, excellent DAC, and relatively mature Rockbox port, the latter of which substantially improved battery life and added features such as parametric EQ, completely gapless playback and AAC audio playback. The Clip+ replaced the discontinued original Clip, with which it shared nearly identical hardware aside from the microSDHC slot.
