Hi All,

The comparison table doesn't help a lot. It only shows manufacture specification. What is really important is not on the table. Please add 3 columns for the Read performance, Write performance and latency. In order to have a good overall view, a good HD performance should also be in graphs for reference and comparison.

I would suggest also a test on USB Flash pens with high capacity.

Thanks for the great work,
Julio

I'd like to add that Transcend 150x is probably the only card in the bunch with SLC (single level cell) memory. Compared to MLC ( multi level cell) memory SLC can handle 10x more read/write cycles. Here's what Supetalent says about the two types:
"Single-level cell (SLC) and multi-level cell (MLC) Flash memory are similar in their design. MLC Flash devices cost less and allow for higher storage density. SLC Flash devices provide faster write performance and greater reliability, even at temperatures above the operating range of MLC Flash devices."
