Can anyone explain what "speed" they refer to when rating these SSD's"
SSD speeds you see on sites like newegg are generally just Crystal Disk Mark scores and are hard to gauge in real world work loads, As for general reviews, they tend to test much hard workloads to see the consistency of the drives performance, drives like Sandisk's Extreme Pro and Samsung's Evo and Pro lines rank up as high as they do because in sustained work loads they have the highest general performance, any ssd will give you a speed boost and in launching and booting programs and windows you will see a massive boost no matter what but its on large files copys and writes and other heavy work loads that the much lower overall performance will show, like in my system i went with the budget Adata Sp550 and its awesome, 10 second boots and lighting faster performance in everything BUT large file transfers, anything over about 3 gigs uses all the fast transfer memory / cache and the drive nearly halts going to 143mb/s to 0mb/s and back up constantly pausing and choking but in small transfers i see 450mb/s+ in transfers and its awesome, generally, smaller drives have cheaper memory and smaller caches that while have solid performance they dont have the sustain for anything overly heavy but do great for general daily use while the higher end and higher rated ssd's have much better memory for longer use and drive life, more write cycles, and much higher performance both overall and in sustained heavy work loads. hope this helps a bit. have a good one
