To achive this read/write speed cardreaders must support at least UHS-I standard and be connected using fast interface like USB 3.0 or better. Use of old readers will reduce speed to about 20 MB/s. Use of USB 2.0 with UHS-I reader gives about 40 MB/s

WD Red NAS Hard Drive 4TB
After 2.5 years of usage, my old backup drive (Seagate Barracuda Green 2TB) failed. Drive usage was minimal, but it was on 24/7. New disk decided to be NAS specialized 4.0 TB. Since I believe, it will be backup for this and next generation of home storage. I hope it will serve more than 2.5 year. So this time disk is WD Red NAS Hard Drive 4.0 TB WD40EFRX.
Before start using it as eSATA backup did some speed tests using USB 3.0 connection to Windows 7 PC.
