Its crap basically, the places it does well are "benchmark" numbers that mean little, where it sucks, is where normal mechanical drives suck and where SSD's beat them by absolutely miles.
On top of that their results are horrible, Crystal disk mark and as ssd should both have the 7200.11 WAY faster than they show it, and 10% cpu utilisation for a single 7200.11, theres something completely wrong with their computer yet they show the results.
Likewise As ssd/CDM both show the 4kb write lower than read(its the other way around on EVERY other bench on every other review in the world) and 4kb 64q threaded results are awful, a C300 is around 220mb/s for the 4kb threaded, a Vertex 2 should be WAY over 100mb/s, they have it around 40-50mb/s.
They've benchmarked it badly, or purposefully shown the momentus better than it is, don't know the site enough to say which. Anyone with half a brain should see a 3.5" 7200rpm drive will get better sequentials than a 2.5" 7200rpm, its a joke.
When you look at the scores in AS ssd, in reality its barely ahead of a normal drive though doesn't cost that much more, but its just worthless.
It sucks at access times(look at random access times in the proper benchmarks, its worse than a single 3.5" 7200rpm drive), it sucks at IOPS, it sucks at sequential read, it sucks, everywhere.
Go for an SSD that will blow it completely away, or get a couple cheapo 3.5" drives in raid.
So horrible review because most of the results are pretty much wrong, and it still looks like a pointless drive, marginally faster than a normal mechanical hdd, at a higher cost, faster in all the wrong places, as slow or slower in the most important ones.
An upgrade compared to utterly crap old 2.5" laptop hdd's, sure, an upgrade to a 3.5" normal drive for a desktop, not even close, a sidegrade at best, a waste of money.
A better review from storage review puts it exactly where it is, in one/two limited situations it can rival a Raptor, in most situations its marginally, and I mean incredibly marginally ahead of other laptop mechanical hdd's, utterly pointless drives.

Check the 4kb aligned random reads are the kinds of results SSD's should have shown in that first review, instead of 140mb/s + they showed, 40mb's, on that graph the momentus would have been dead last, so far away from competitive performance its laughable.
