We just got a new Samsung Galaxy Note 4, and this device is very fast… and its internal flash storage is extremely fast – 223.53MB/s read speed, and 131.52MB/s write speed (see the screenshots below).
So very fast device, requires deserves one of the fastest SD cards in the world – SanDisk 32GB Extreme PRO microSDHC UHS-I Card (it has UHS speed class 3 (U3)). And if you put this microSD card into regular smartphone, it may not unleash its all power, because of slow/cheap SD card controller, but it exceeds anything we have seen before when put into the new Galaxy Note 4. Again, see the screenshots below, it can achieve super fast speed for the SD cards on the mobile device – 61.40MB/s read, and 47.84MB/s write speed (Advertised speeds: Read 95MB/s, write 90MB/s).
Today we have released a new version of SD Bench.
We didn’t plan to release this early, however thanks to your feedback we have added a new Speed Test / Benchmark category — Cached reads. Cached reads are reads that fully or partially comes from the RAM cache instead of SD card or phone memory. These results belongs to neither RAM, nor flash memory, so we created a new category.
In computer science, a cache is a component that transparently stores data so that future requests for that data can be served faster.
The keyword here is “Faster”. Now we have 3 separate speed categories:
