Q

Consumer SSDs vs. enterprise SSDs

Dennis Martin, president of Demartek, discusses the differences between consumer and enterprise SSDs in this Expert Response.

Is there an equivalent between enterprise SSDs and consumer SSDs just as there is for enterprise and consumer hard disk drives?

Yes, enterprise SSDs are different than consumer or “client” SSDs. Enterprise SSDs need to be able to handle many reads and writes for things such as database files, indexes, logs and other high-transaction types of operations. Enterprise SSDs are held to higher standards for performance, endurance, error recovery and continuous operation just as enterprise HDDs are held to similar higher standards.

Consumer-grade SSDs, like their desktop HDD counterparts, are not held to the same standards. For example, enterprise-class SSDs, like enterprise-HDDs, are expected to operate 24 hours per day and 7 days per week, while consumer-grade SSDs and HDDs are typically built to operate 8 to 10 hours per day and five days per week.

Two of the industry standards bodies for SSDs, the Joint Electron Device Engineering Council (JEDEC) and the Storage Networking Industry Association (SNIA), have each published specifications for endurance (JEDEC) and performance (SNIA) that distinguish between enterprise and client SSDs.
