Intel X25-M 50nm 80GB SMART Attribute

What does attribute E2h, E3h and E4h represent? Apparently since the second gen (34nm), they represent some "Timed Workload" thing, but they don't in the first gen (50nm).

Hello Tom Yan,

The SMART Attributes and description are the same for all Intel SSD's.

As you suggested, E2, E3 and E4 are related to Timed Workload indicators. However, this information was not documented in the datasheet or the Intel® SSD X25-M Series.

For more information about these and other SMART attributes, please check the following documents:

Perhaps this is partly right. But I think it's more like a bogus one.

I mean if try to send the 40h subcommand to it to reset the timers, the values indeed become 65535 as expected from the Timed Workload attributes. However, it seems X25-M doesn't collect any data and the number would be "re-reset" to 4294967295 (0xffffffff), 281474976710655 (0xffffffffffff) and 4294967295 (0xffffffff) respectively after a power cycle.

Hello Tom Yan,

The timer and other functions of Timed Workload indicators are not supported on the Intel® SSD X25-M Series. You may see some information about Timed Workload in the SMART Attributes, however, it is not supported and won't work like it does with newer SSD's.

For this reason, this was not documented in the datasheet of the Intel® SSD X25-M Series, as it was with the Intel® Solid-State Drive 320 Series.
