This Just In: OCZ's Vertex 3 MAX IOPS 120GB, The New Mid-Range King?

I mentioned in our Mid-Range SSD Roundup that most SSD vendors like sampling the best balance of capacity/performance when it comes to SSD review samples. For the SandForce SF-2281 with 25nm NAND that just happens to be 240GB. Unfortunately there's a pretty big fall off in performance when going from 240GB to 120GB due to the decrease in total number of NAND die (8GB per die x 32 die vs. 16 die). I've explained this all before here.

Enter OCZ's MAX IOPS drive. Using 32nm Toshiba Toggle NAND instead of 25nm IMFT ONFI 2.x NAND the die capacity drops to 4GB, which means you get twice as many die per NAND device. The end result? 240GB Vertex 3 performance for slightly more than 120GB Vertex 3 pricing.

 

I ordered the 120GB MAX IOPS drive at the beginning of the week and just got it in yesterday so I've only had a small amount of time to test with it thus far. Check out the 120GB MAX IOPS drive vs. the Intel SSD 510 in Bench using our 2011 storage test suite. Expect the full review in the coming days.

Correction: OCZ Vertex 3 Random Read Performance Data

A huge thanks goes out to AnandTech reader Andrei and some very attentive Xtreme Systems forum members. I just got an email pointing me to this thread where one particular number from our OCZ Vertex 3 and Intel SSD 510 articles was called into question. The problem? The 4KB random read numbers for the Vertex 3 were supiciously high. The reality? They were incorrect. 

I was just alerted to the error and quickly powered up the SSD testbed to recreate the test. It looks like the original numbers were either run at a queue depth of 32 or accidentally copied from one of the runs of 4KB random write tests. Either way the number was incorrect and has been fixed in all affected articles.

The updated numbers don't change our conclusions. The Vertex 3 is still the fastest next-generation SSD we've tested thus far and it still maintains a random read performance advantage over the Intel SSD 510.

The integrity of our test data is something we all take very seriously here. Errors like these do you a disservice and hurt the reputation I've worked so hard over the past 14 years to build. I do hope this oversight hasn't negatively impacted your opinion of AnandTech - we aren't perfect, but we strive to be. I do apologize to all of you for the error and I will be restructuring how I run and record my Iometer tests to avoid this particular issue from cropping up again. 

My sincere thanks goes out to Andrei and the XS folks who helped track down the error and inform us of its existence.

OCZ Vertex 3 Pro Preview: The First SF-2500 SSD

For the past six months I've been working on research and testing for the next major AnandTech SSD article. I figured I had enough time to line up its release with the first samples of the next-generation of high end SSDs. After all, it seems like everyone was taking longer than expected to bring out their next-generation controllers. I should've known better.

At CES this year we had functional next-generation SSDs based on Marvell and SandForce controllers. The latter was actually performing pretty close to expectations from final hardware. Although I was told that drives wouldn't be shipping until mid-Q2, it was clear that preview hardware was imminent. It was the timing that I couldn't predict.

A week ago, two days before I hopped on a flight to Barcelona for MWC, a package arrived at my door. OCZ had sent me a preproduction version of their first SF-2500 based SSD: the Vertex 3 Pro. The sample was so early that it didn't even have a housing, all I got was a PCB and a note:

OCZ Vertex 3 Preview: Faster and Cheaper than the Vertex 3 Pro

Last week OCZ pulled the trigger and introduced the world’s first SF-2000 based SSD: the Vertex 3 Pro. Not only was it the world’s first drive to use SandForce’s 2nd generation SSD controller, the Vertex 3 Pro was also the first SATA drive we’ve tested to be able to break 500MB/s on both reads and writes. Granted that’s with highly compressible data but the figures are impressive nonetheless. What wasn’t impressive however was the price. The Vertex 3 Pro is an enterprise class drive, complete with features that aren’t exactly in high demand on a desktop. As a result the V3P commands a premium - the drive starts at $525 for a 100GB capacity.

Just as we saw last round however, if there’s a Vertex 3 Pro, there’s bound to be a more reasonably priced non-Pro version without some of the enterprisey features. Indeed there is. Contained within this nondescript housing is the first beta of OCZ’s Vertex 3 based on a SandForce SF-2200 series controller. The price point? Less than half of that of the V3P:

Pricing Comparison 128GB256GB512GBOCZ Vertex 3 Pro$525 (100GB)$775 (200GB)$1350 (400GB)OCZ Vertex 3$249.99$499.99N/A

At an estimated $250 for a 120GB drive the Vertex 3 is more expensive than today’s Vertex 2, but not by too much nor do I expect that price premium to last for long. The Vertex 2 is on its way out and will ultimately be replaced by the V3. And SSD prices will continue to fall.

Read on for our full preview of the Vertex 3.

OCZ'z Vertex Pro 3 Demo: World's First SandForce SF-2000

A few months ago SandForce announced its second generation SSD controller: the SF-2000 series. The specs SandForce released at the time were almost too good to be true. As a refresher here’s what we saw back in October of last year:

SandForce is promising a single enterprise level drive that can deliver 500MB/s sequential reads and writes (for highly compressible data), and up to 60K IOPS for 4KB random reads and writes. That’s not an evolutionary improvement, that’s more than a doubling of what most of the competition can do today. Even compared to existing SandForce drives it’s a huge increase in performance. But as I’ve heard many times before, anyone can put out a promising PDF.

Read on to find out if OCZ's beta Vertex 3 Pro can live up to the expectations.
