iMac 5K late 2015 256GB SSD performance test

[Jason32]

I've done a quick 256GB ssd performance test, check this out:

1860MB read speed is impressive, my 2014 model could only do around 700MB.

I've got the 512GB, getting a little better write speeds than the 256 in the video. Anyone bench the 1TB?

So there's no need to go for the 512 GB SSD then if you don't absolutely need the extra space - speed wise that is.

Write speed on 512 is faster but I think it wouldnt matter in real world.

Thats a big jump from 700MB to 1860MB from 2014 to 2015

Yes it is. It started with the MBP.

So Apple's BTO SSD are now better than any after market SSD out there.

That's why I'd rather go with SSD build in, rather than a spinning or fusion drive. Fusion drives are not 2000MB/s read, even with the built-in SSD.

Yes I just love the speed the apps open...wow
