A Look at Enterprise Performance of Intel SSDs ~ Computer Hardware Mall

For the majority of the history of AnandTech we've hosted our own server infrastructure. A benefit of running our own infrastructure is that we're able to gain a lot of hands on experience with enterprise environments that we'd otherwise have to report on from a distance.

When I first started covering SSDs four years ago I became obsessed with the idea of migrating nearly every system over to something SSD based. The first to make the switch were our CPU testbeds. Moving away from mechanical drives ensured better benchmark consistency between runs as any variation in IO load was easily absorbed by the tremendous amount of headroom that an SSD offered. The holy grail of course was migrating all of the AnandTech servers over to SSDs. Over the years our servers seem to die in the following order: hard drives, power supplies, motherboards. We tend to stay on a hardware platform until the systems start showing the signs of their age (e.g. motherboards start dying), but that's usually long enough that we encounter an annoying number of hard drive failures. A well validated SSD should have a predictable failure rate, making it an ideal candidate for an enterprise environment where downtime is quite costly and in the case of a small business, very annoying.

Our most recent server move is a long story for a separate article but to summarize the move, we recently switched hosting providers and data centers. Our hardware was formerly on the east coast and the new datacenter is in the middle of the country. At our old host we were trying out a new cloud platform while our new home would be a mixture of a traditional back-end with a virtualized front-end. With a tight timetable for the move and no desire to deploy an easily portable solution at our old home before making the move we were faced with a difficult task: how do we physically move our servers half way across the country with minimal downtime?

Thankfully our new host had temporary hardware very similar in capabilities to our new infrastructure that they were willing to put the site on as we moved our hardware. The only exception was, as you might guess, a relative lack of SSDs. Our new hardware uses a combination of consumer and enterprise SSDs but our new host only had mechanical drives or consumer grade SSDs on tap (Intel SSD 320s).

In preparing for this move I realized we hadn't publicly discussed the performance and endurance issues associated with using consumer SSDs in an enterprise environment. What follows is a discussion of just that. Read on...
