Acording Hosting Expert, Laura Bernheim,

“This is a rare battle between two VPS specialists! To be fair, Hostwinds and DreamHost both offer the full range of shared, VPS, cloud, and dedicated services, but these premium providers truly excel at the higher levels of hosting. Hostwinds gives customers managed or unmanaged options of both Linux and Windows virtual servers, while DreamHost maintains a laser-like focus on premium managed WordPress hosting through its DreamPress platform. Both offer above-average uptime guarantees, with Hostwinds promising a 99.999% SLA and DreamHost holding a slight edge at 100%. With such razor-thin margins, take a look at our reviews below to see the winner.”..

Hostwind:
The standard shared hosting services compete with the likes of InMotion Hosting, SiteGround, and A2 Hosting. Modern solid-state drives place Hostwinds and the others in a somewhat more expensive hosting bracket, but savvy customers will notice the value.

Between the SSDs and LiteSpeed web servers, Hostwinds ekes out 500% faster performance compared with typical shared hosting plans. Combined with the bevy of unlimited features (bandwidth, disk space, subdomains, email accounts, databases, and FTP accounts), we love how Hostwinds matches superior services with affordability.
