7-Way SSD Round-Up: Sandforce vs. JMicron

2 thumbs up

All of the drives featured in this article conform to the same 2.5" form factor with 9.5mm Z-Height and all of the drives have identical connector configurations (just SATA, no USB), so there's little to differentiate one from another from a pysical standpoint, save for their decals and the colors of their enclosures.  First up is the OCZ Vertex 2...



  
Note: The OCZ Vertex 2 100GB and 120GB Drives Are Physically Identical

The 100GB OCZ Vertex 2 shown here represents the current high-end of OCZ's SandForce 1200 based solid state drives, in terms of it firmware configuration (a 200GB model is also available). The Vertex 2's firmware does not impose the the 4K random write speed limitation mentioned on the previous page, hence the higher IOPS rating in the specs above versus the Agility 2. As you can see, the drive is rated for 285MB/s reads with 275MB/s writes (sustained writes up to 250MB/s). It has TRIM support built-in and it carried a 3-Year warranty.

The OCZ Agility 2 and Vertex 2 are very similar products (the drive pictured here is also a 100GB model). In fact, they're virtually identical in terms of their hardware. Of course, the Agility 2 bears different branding, but other than its decals, the only major difference between it and Vertex 2 is its firmware configuration. The Agility 2's firmware limits random write performance, hence its lower IOPS rating (10,000 4K random writes versus 50,000 with the Vertex 2). As you'll see in the performance data, however, the random write limitation of the Agility 2 doesn't hinder its performance much at all in most workloads.

Nice Round-Up again Marco I like these reviews cause its head to head and the results are right there for you to see. With that said SSD's are the future until then my Caviar Black will have to hold me over.

Nice SSD read

I'm starting to really like the SandForce drives. They all seem to perform very well.

Me too, just waiting on the prices to relax some more. I can't afford them otherwise.

OCZ Vertex 2 lookin pretty good.  I'd like to get about 5 of those in RAID 5.

one day........

I just broke down and ordered an OCZ 60-GB Agility-2 SSD Drive.

Soon I'll know what the heck everyone else has been crowing about,.....I guess.
