Storage Questions (2242 vs 2280) and expansion cards

Had a few questions regarding storage.

  1. I’m looking to put in a double-sided 2242 and I was wondering if it would fit as it needs 3.5 mm height. Looking in specific at the Sabrent Rocket 2242 which appears to be an M key (5 on right side which is the same as the WDSN750). Also, since it is shorter than the 2280, is there a screw placement for it? Does it matter if it isn’t screwed?

  2. For the expansion cards, what is the TBW rating for the flash?

  3. Do all the expansion cards sit flush with the edge of the laptop? The picture on the blog post shows it extended out from the case, which I’m assuming to show the labelling.



Double sided SSDs should fit. There isn’t a screw position for 2242, and the SSD really needs to be fastened down. There are some 2242->2280 lengthening adapters out there though.

The Expansion Cards do sit flush in normal use. For the TBW ratings, I’m looking for the spec.


For those who haven’t met the term TBW before, it’s TeraBytes Written (ie how much you can write before the SSD fails). See Wikipedia on SSD failures.


For the Expansion Cards, the 250GB is rated to 38.9 TBW, and the 1TB is rated to 150.39 TBW.


Excellent. Thanks for the info.
