SanDisk DF4064 vs SanDisk DF4032

SanDisk DF4064

► remove from comparison

SanDisk DF4032

The SanDisk DF4032 is an eMMC chip with advertised capacity of 32 GB. We first tested this storage solution in 2017.

Performance

In our testing, the storage solution delivered sequential read and write rates of about 150 MB/s and 90 MB/s, respectively (per CDM 3). These numbers are in line with quality 2.5" HDDs and are hardly record-breaking; then again, systems featuring such a storage solution are very likely to be low-end systems bottlenecked by their CPU rather than anything else.

Power consumption

eMMC chips tend to consume several times less energy than proper SSDs.
