Apple adds 256GB, 512GB flash storage upgrade options for iMac

Build-to-order iMac options from Apple's official online store now include either 256 or 512 gigabytes of flash storage for both the 21.5- and 27-inch models.

Choosing 256 gigabytes of all-flash storage will add $300 to the entry-level iMac price, while 512 gigabytes will cost an extra $600. The new options were first noticed on Thursday by MacRumors.

Previously, buyers of the 21.5-inch iMac had no all-flash options when customizing their order. The choices were restricted to a default 1-terabyte 5400rpm Serial ATA drive, or spending an additional $250 for a 1-terabyte hybrid Fusion Drive.

As for the 27-inch iMac, the only flash drive available previously was a massive 768-gigabyte option that cost an additional $900.

All iMacs in default configurations are advertised to ship within 24 hours from Apple's online store. Availability of the all-in-one desktops was severely constrained through the end of 2012, which prompted Apple CEO Tim Cook to admit last week he wished he had held off on launching the thinner iMacs until 2013.

Apple's apparent production issues were said to have stemmed from a unique screen lamination process that allowed Apple to achieve the ultrathin design. With those issues now seemingly addressed, Apple is offering more options for internal storage.
