Was looking for an SSD for an external case as i've killed a few HDD from shaking in my man bag whilst running for the train.
These are surprisingly cheap and have awesome reviews on amazon and feedback on store link with a few screenshots from crystaldiskmark from users.
There is feedback from someone on store who ordered a 360Gb but real measured capacity was only 335Gb.. i found an explanation on one of the amazon reviews and someone had explained that there is "24gb of reserved Z sector" where if a bad sector error is detected it is moved immediately into the reserved area.
Mod: Prices updated to include GST
So it's $90.48 US / $126.25 AU inc. GST for the 512GB.
KingSpec are a very good budget brand of SSDs and have been around forever! The blue and orange are sexy af too :) I have two KingSpec 2242 M.2 SSDs (128GB & 256GB) in my laptop and they've been going strong for 18 months now.
