I rarely do hosting reviews unless the host is bad. This is my Siteground Hosting Review: Stay Away.
On the surface, Siteground hosting looks like good. And they are for most things except one: their FTP service is extremely slow and inconsistent. For example, sometime when I upload a file, it takes a few seconds, as it should. But more often, it takes 30-60 seconds to upload a file. And I’m talking about small files; eg, 656 bytes.
I called them to complain and got the run around and they said there were no problems. But I’ve worked on about 8 sites on Siteground the the FTP is always an issue. It is important to note that I NEVER have this slow FTP problem with wp-engine, Bluehost, Hostgator, DreamHost.
