So, I've been told by a few people that SSDs are 'better' when bought in certain increments, for example:

60gb, 120gb

aren't as good as

64gb, 128gb

Is this true?

If it is true, how comes?

Looking to buy an SSD so would like to know as now would be a good time to find out :D
 
The more chips the SSD has, the more channels it has to write to, so the bigger the SSD the faster it can write, this tends to level out around 250GB, always get at least 128GB if you want fast writes though, since 64GB drives have the least amount of channels.

Though 60, 64GB and 120, 128GB drives will have similar performance to each other.
 
It's also a case of some SSDs having reserved space for wear levelling to increase longevity. A 120GB SSD actually has 128GB of storage, it's just that the firmware cuts a slice off and uses it for wear levelling.

But yes, having more actual chips on the drive helps as you get more bandwidth. It's a bit like having 2x4GB RAM sticks in dual-channel mode is faster than having a single 8GB stick. The storage space is the same, but since you have two channels in and out of that space your performance goes up.

[I see someone else got in with the same answer while I was typing!]

Also, from what I've read they all basically have 64/128/256 MB of flash ... its just, I think, that some controllers reserve part of that for "housekeeping" activities (probably related to wear levelling etc) and don't make that visible to the user whereas others make it all visible ... but then there's the recommendation you see of leaving 10-15% space free to allow for wear levelling etc to operate efficiently so it may be a matter of whether this extra space is reserved and hidden by the controller.

Of course a side-effect of this is that 60/120/240MB drives are probably using different controllers to 64/128/256 drives so performance differences will be down to the controllers.
 
So in effect, what I heard WASN'T true?

Would it be better to go for one that doesn't have the wear levelling feature then?

Also while I have your attention, best PC mag to buy for some reviews? :)

building my PC and what to get the best for my money (as we all do) and just want a good mag to read but theres so many.
 
sit in WH smiths and have a read most mags are online also tho or most articles can be found online

i think 250 ish drives have the sweet spot at the moment
how they size then depends on the controller used and the manufacturer

most are still plumping for the crucial m4 right now i guess overall still

pc pro
pc shopper
custom pc
pc gamer

i guess a few that i pick up sometimes
 
crucial m4.

got it.

time to do research, so many things to research, it's taken me a week to decide on getting a 3570k over a 2500k :(

it doesn't help being indecisive.

in regards to the mags, thanks, but i meant specifically out of those which is the best, but I guess that's up to me to decide huh :)

thanks for your help, all of you.
