Is it worth it to get the retail version of the X-25 m g2 or should I just go with OEM, I'm asking this because I am unsure of what perhipals come with the Retail versions of Solid State Drives and if they are needed for installation
The last two letters of the Intel X25-M product code is the shipping volume/packaging; though its the same product, Intel wants to give discounts to companies that listen to Intel, but others will have to pay 'full price'. This kind of business mentality is widespread unfortunately, and prevents real market competition.
So just pick the cheapest version, as long as its the X25-M G2 you should be good.
Oh i forgot, since SSDs are 2,5" form factor (the same as notebook HDDs) you may want to use a 3.5" -> 2.5" bracket, so you can fit the SSD in the bays designed for normal desktop HDDs, which are 3,5", while notebook HDDs and SSDs are 2.5".
It could look like this:
You don't absolutely need it though, as SSDs have no moving parts there should be no important reason to just put them at the bottom of your case secured with some tape. That's actually what i'm using for my SSDs.
