By default, Western Digital [http://www.westerndigital.com/en/products/index.asp?Cat=2&Language=en Enterprise Drives] such as Raptor, Caviar RE2 and RE2-GP (RAID Edition) come with TLER Read "Disabled" (0 seconds) and TLER Write "Enabled" (7 seconds) while [http://www.westerndigital.com/en/products/index.asp?Cat=3&Language=en Desktop Drives] such as Caviar SE, SE16, and GP come with TLER Read and Write Disabled (0 seconds).

The ability to change the TLER option on Western Digital Desktop and Enterprise hard drives coincides with the current trends in desktop computing allowing the user to have the flexibility of buying a start-up computer with a single desktop class hard drive and then upgrading to two or more drives in the future. Most of the motherboard manufacturers these days use chipsets from [http://www.intel.com/products/desktop/chipsets/index.htm?iid=chipsets_body+dt_all Intel] and [http://www.nvidia.com/page/mobo.html nVidia] that include on-board RAID controllers as a standard option and anywhere from 4, 6, or up to 810 SATA ports allowing for easy upgrades to multiple hard drives and RAID capability without the requirement of purchasing specialized add-on cards. Additionally, having the choice of changing the TLER option gives the user the flexibility of purchasing the high performance drives such as the Western Digital Raptor that have TLER enabled and that are designed to run in a RAID array and using them as stand-alone single drives in their desktop computers and disabling the TLER option to enable better data recovery and lower chance of corruption and drive failures.
