Micron Returns to the microSD Card Market with the Micron c200 Series: From 128 GB to 1 TB

About a year and a half after discontinuing its Lexar consumer
storage business, Micron is making a comeback with a series of
microSD cards that it’s demonstrating at Mobile World Congress.
The company believes that the market of memory cards is set to
grow and since it now has the right type of NAND memory for
these applications, it makes a great sense to launch its
Micron-branded microSD products.

Micron’s c200-series microSD cards range in capacity from 128
GB to 1 TB and are based on the company’s 96-layer 3D QLC NAND
flash as well as in-house-developed controller supporting
LDPC-based ECC. The cards are rated for up to 100 MB/s
sequential write speed and up to 95 MB/s sequential read speed
(the 128 GB version may be a bit slower). The Micron c200 cards
also carry the SD Association’s A2 and V30 badges, which means
that they offer random performance of at least 4000 read IOPS
and 2000 write IOPS; support capabilities like command queuing,
caching, and self-maintenance, as well as a minimum write speed
of 30 MB/s.

Micron will announce detailed pricing and availability
information about the c200-series sometimes in the second
quarter. At this point the company is not making any official
commitments to return to the reteail channel. However retail is
the most natural and straightforward way to sell microSD cards,
so it would make a great deal of sense for Micron to partner
with large retailers and retail chains.

The manufacturer believes that 3D QLC memory provides the right
balance of cost, performance, and reliability (when coupled
with an appropriate controller) for consumer storage. In
particular, Micron says that its 96-layers 3D QLC memory can
bear 1500 program/erase cycles (with a particular controller),
which should be plenty sufficient for most consumer workloads.

Meanwhile, the market of high-capacity microSD cards is set to
grow. According to IHS data cited by Micron, total available
market for memory cards featuring 128 – 1 TB capacities will
increase to $3.5 billion in 2021, up from around $2.3 billion
in 2019.
