Bug in 320 specs

Comparing 320 series SSD to the new DC S3700 one I found a huge difference in Random Write (100% Span) field http://ark.intel.com/compare/71916,56569 http://ark.intel.com/compare/71916,56569

What does this Random Write (100% Span) mean?

Is it an error in 320 spec? Or may be you forget to fill it for DC S3700... there shouldn't be a 24000% difference in any parameter!

Hello Dwarf,

The information for both drives regarding the Random Write (100% Span) is correct. You may verify this from the product specifications for each model:

Intel® SSD 320 Series Product Specifications:

Keep in mind the Intel® SSD DC S3700 is a performance drive designed for data centers.

Random Write (100% Span): Speed with which the SSD is able to record data to arbitrary locations in the memory, across the entire span of the drive. Measured in IOPS (Input/Output Operations per Second).

Hi Dwarf and Joe,

I saw this post a few days ago and the data for the 320 was incorrect at that point. I requested an update to ARK and that has been completed so the data is correct now.

Sorry for not updating this thread sooner.

Cool! But now IOPS for 8Gb span and for 100% span are the same... little bit strange though. Why there were two different counters if it is always identical.

One more to say. 320 series have 128bit AES Hardware Encryption it wasn't mentioned in ark
