This is clear from what Intel have already said and what the reviewers have "regurgitated". SSDs with "M" in the part number are consumer/mainstream type devices using Intel/Micron MLC flash parts and come with a 3 year warranty. The "E" parts numbers are intended for enterprise users and will use Intel/Micron SLC flash parts. Performance characteristics, pricing and warranty have not been published - altough the rumored numbers look very good. The "E" series drives are already sampling, so it won't be very long before we know all the details. My guess is that Sun will be basing their upcoming SSD products on Intel technology... My reason for posting this to the list is to try to be helpful and let folks know about SSD related news/reviews that they may have missed. There are lots of applications for "M" series SSDs in a ZFS based environment, for example, any application where the workload is mostly read only and the access pattern is random. Serving up CD and DVD sized ISO images comes immediately to mind. In this application a single M series drive providing 4,500 IOPS would be cost/power/cooling/size/price competitive against five 73Gb 15k RPM SAS drives.
