Does 730 use HET or SET MLC?

Jump to solution

The 3700, 3710, and 3610 all use High Endurance Technology (HET) MLC, with the first using 25nm and the other two using 20nm. The 3510 uses Standard Endurance Technology (SET) MLC. The 730 uses 20nm Compute-Quality Components. So which type of MLC does the 730 use: HET or SET?

Hello paramountain,

The Intel® SSD 730 Series uses Standard Endurance Technology.

It is a high performance client SSD, recommended for PC enthusiast and Workstation systems. The Intel® SSD 730 Series provides better performance and endurance than other client SSD's.

It does not feature High Endurance Technology (HET) as noted in the http://ark.intel.com/products/81038/Intel-SSD-730-Series-240GB-2_5in-SATA-6Gbs-20nm-MLC Intel® SSD 730 Series (240GB, 2.5in SATA 6Gb/s, 20nm, MLC) Specifications

Thanks for the reply. Yes, the Ark page does indeed state that the 730 does not employ HET. I would never have guessed that the Ark page contained data that the product brief PDF omitted. http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ssd-730-series-brief.pdf http://www.intel.com/content/dam/www/public/us/en/documents/product-briefs/ssd-730-series-brief.pdf

The Ark page brought up another question. It states that the 730 does not have "Enhanced Power Loss Data Protection." However, the photos at Storage Review show that the 730 has the same red capacitors that the 3700 has. Does "Enhanced Power Loss Data Protection" imply more than two capacitors or does the Ark page contain a misprint?

The Intel® SSD 730 Series incorporates power loss protection circuitry, capacitors and firmware support to help protect user data.

All data that has been completely transferred over the SATA Phy and acknowledged on the SATA Transport from the the drive to the host will be written to NAND.

Thanks for the reply. So the Ark page for the 730 is in error and should say "Yes" for "Enhanced Power Loss Data Protection."

Hello paramountain,

Power loss protection is not featured in the specifications because it has not been fully validated like it is on Data Center SSD's, even though the technology is operational.

As you suggested in a different post, it is not recommended to use Consumer drives for tasks where an Enterprise SSD is required.

Ah, not validated, that's something Scott would appreciate.

As for enterprise versus consumer SSDs, I have the opposite desire, to use enterprise drives where consumer ones would normally be used, in a desktop. The power-loss feature is a great one, but manufacturers never put it on consumer drives, believing (probably correctly) that most people use SSDs for laptops which use a battery. That's why I like the 730.

Thanks for the details.
