First, let's consider performance. The focus of our testing in this review was to juxtapose the Agility's performance and that of its predecessor, the Apex. Our first finding in testing was that the Agility improved quite consistently upon the Apex's sequential transfer speeds. With reads of almost 240 MB/s and writes faster than 150 MB/s, the Agility certainly delivers excellent sequential transfer performance.
As if the 20-30 MB/s increase transfer speed wasn't enough, the Agility also crushes the Apex in transfers of small files. This large increase in < 32KB sized transfer speeds means hassle free use as a system drive for the Agility. Indeed, for the past few weeks I have been using the Agility as my Vista Ultimate system drive and have experienced zero stuttering or other types of trouble.
All of this improvement in performance is likely attributable to the welcome change from JMicron RAID controllers to an Indilinx controller with 64MB of cache. This controller choice alone puts the Agility easily above the majority of mainstream SSD competition.
At this point you may think that this drive is too good to be true. This exceptional performance does not, however, come at a premium. Most 120GB MLC SSDs cost somewhere in the unhappy range of 300-350 USD. But, never fear, you can find the Agility online at popular resellers for about 270 USD, which is practically as cheap as 120GB SSDs get. Ouch, competition, that one stings.
I must say, I am impressed with the OCZ Agility. High performance, low price, all around great product. In my opinion, if you're in the market for an SSD, there is little questioning that this is the drive to get. It makes very little sense for the average user to pay more for another drive at little to no gain in performance.
The OCZ Agility 120GB earns the OCIA.net Gold Seal of Approval.
