OCZ's Vertex 2 Pro Preview: The Fastest MLC SSD We've Ever Tested

Final Words
SandForce started work on its controllers back in 2007. The late start meant a late arrival to the party. Even today we’re looking at another 1 - 3 months before we see widespread availability of SSDs based on the SF-1200 or SF-1500. I guess it’s more fashionably late than anything else, because this thing is good.
The OCZ Vertex 2 Pro is the fastest single-controller MLC SSD I’ve ever tested, and it’s not even running final firmware. It’s quite telling that SandForce decided to make its first public showing with OCZ. Perhaps all of the initial hard work with Indilinx in the Vertex days paid off.
The controller and product both look very good. The only concern for the majority of users seems to be price. For the enterprise market I doubt it’ll be much of an issue. The Vertex 2 Pro should come in cheaper than Intel’s X25-E in a cost per GB sense, but for high end desktop and notebook users it may be a tough pill to swallow. Especially for a controller whose reliability will only be proven over time. I’m curious to see what the cheaper SF-1200 based SSDs will perform like. I’m hearing that they offer the same sequential read/write speed, but have lower random write performance.
OCZ says they will continue to work with Indilinx to bring out new products based on its controllers. SandForce simply adds to the stack.
Then there's Intel. Current roadmaps put the next generation of Intel SSDs out in Q4 2010, although Intel tells me it will be a "mid-year" refresh. For the mainstream market the capacities are 160GB, 300GB and 600GB. I'm guessing we'll see 160GB down at $225, 600GB at $500+ and the 300GB drive somewhere in between. The X25-E also gets a much needed upgrade with 100GB, 200GB and 400GB capacities.
Competition is a good thing. We need companies to not only keep Intel aggressive on price, but competitive on features as well. Indilinx did the former and it looks like SandForce is going to do the latter.

Kingston has released a new SSD series (V+) with the Samsung controller. I hope Anandtech will review it soon. Other sites are not reliable, as they test only sequential read/writes.Bobchang - Wednesday, January 20, 2010 - link
Great Article!it's awesome to have new feature SSD and I like the performance
but, regarding your test, I don't get the same random read performance from IOMeter.
Can you let me know what version of IOMeter and configuration you used for the result? I never get more than around 6000 IOPS.

Anand,Your SSD benchmarking strategy has a big problem: there are zero real-world-applicable comparison data. IOPS and PCMark are stupid. For video cards do you look at IOPS or FLOPS, or do you look at what matters in the real world: framerate?
As I said in my post here (http://tinyurl.com/yljqxjg)">http://tinyurl.com/yljqxjg), you need to simply measure time. I think this list is an excellent starting point, for what to measure to compare hard drives:
1. Boot time
2. Time to launch applications
_a) Firefox
_b) Google Earth
_c) Photoshop
3. Time to open huge files
_a) .doc
_b) .xls
_c) .pdf
_d) .psd
4. Game framerates
_a) minimum
_b) average
5. Time to copy files to & from the drive
_a) 3000 200kB files
_b) 200 4MB files
_c) 1 2GB file
6. Other application-specific tasks
What your current strategy lacks is the element of "significance"; is the performance difference between drives significant or insignificant? Does the SandForce cost twice as much as the others and launch applications just 0.2s faster? Let's say I currently don't own an SSD: I would sure like to know that an HDD takes 15s at some task, whereas the Vertex takes 7.1s, the Intel takes 7.0s, and the SF takes 6.9! Then my purchase decision would be entirely based on price! The current benchmarks leave me in the dark regarding this.

I think the point made is a good one for an additional data point for the decision buying process. Keep all the great benchmarking data in the article and just add a couple of time measurements so, people can get a feel for how the benchmark numbers translate to time waiting in the real world which is what everyone really wants to know at the end of the day.Also, Anand did you fill the drive to its full capacity with already compressed data and if not, then what happens to performance and reliability when the drive is filled up with already compressed data. From your report it doesn't appear to have enough spare flash capacity to handle a worse case 1:1 ratio and still get decent performance or a endurance lifetime that is acceptable.

Real world top-level data should be the primary focus and not just "an additional data point".This old article could not be a better example:
http://tinyurl.com/yamfwmg">http://tinyurl.com/yamfwmg
In IOPS, RAID0 was 20-38% faster! Then the loading *time* comparison had RAID0 giving equal and slightly worse performance! Anand concluded, "Bottom line: RAID-0 arrays will win you just about any benchmark, but they'll deliver virtually nothing more than that for real world desktop performance."

Icing on the cake is this latest Vertex 2 drive, where IOPS don't equal bandwidth.It doesn't make sense to not measure time. Otherwise what you get is inaccurate results to real usage, and no grasp of how significant differences are.

The better way to test rather then hopping on your mac and thinking thats the end-all be-all of the world is to throw this drive into a server, vmware or xenserver... and create multiple VD sessions.1- see how many you can boot up at the same time and run heavy loads.
The boot ups will take the most IOPS.
Sorry but IOPS do matter so very much in the business world.
For stand alone drives, your read writes will be what your are looking for.

This is all great, finally a company that realizes the current SSD's are too cheap and have too much capacity and that people have too much money.Oh wait..
