OCZ’s Vertex Limited Edition Review & SSD State of the Union

Sequential Read/Write Speed
Using the latest build of Iometer I ran a 3 minute long 2MB sequential write test over the entire span of the drive. The results reported are in average MB/s over the entire test length:
Saturating the bandwidth offered by 3Gbps SATA, the Crucial RealSSD C300 and OCZ Vertex LE are the fastest you can get. However, pair the C300 with a 6Gbps controller and you'll get another 70MB/s of sequential read speed.
The Toshiba based SSDNow V+ does a bit better than the Samsung based OCZ Summit at 224MB/s. You're still better off with an Indilinx drive though.
Despite being based on an architecture that was first introduced in 2008, the X25-Ms are still able to nearly saturate the SATA 3Gbps bus.
The sequential write speed of the SandForce SF-1500 controller is just ridiculous. OCZ is able to virtually saturate the SATA 3Gbps bus at 252.7MB/s. In the past it would take us two SSDs or a whole crapton of hard drives to get that sort of sequential write throughput. The RealSSD C300 is a distant second place at ~200MB/s, which is still not bad. Kingston's SSDNow V+ actually does well at 192.5MB/s here.
The Intel drives are still banished to the bottom of the chart with their <= 100MB/s sequential write speeds.

I just bought an OCZ Agility based on your benchmarks, the ones suggesting the drive is capable of 160MB/s writes. However it has been confirmed by several other customers that the current batch being shipped by NewEgg uses different chips in the OCZ lottery which comes up with 100-130MB/s writes. This is very significant for people buying this drive for video capture related purposes, since 100 is hardly any better than the average 70 on a standard HDD.The Agility's random writes that you show in the charts and latest article are also almost double of the drives being shipped right now. After countless tweaks I can barely do 7MB/s, forget 12.
I understand the Agility is a dated drive, but it's still very popular due to recent sales ($130 for 60GB) and I think it would help your readers to take a look at updated performance numbers that are more realistic to what they will actually get.
Also there's no refunds with SSDs, so anyone buying into these charts will just have to live with what they get.

FYI... 100 vs 70 is THIRTY PERCENT FASTER DUH? 30% is HUGE in regards to technological competition/advancements. Where have you been all these years? Show us a 30% performance gain (aside from SSD beta testing and new releases) in 1-2 mechanical HD generations... Umm you CAN'T>.<AnnonymousCoward - Tuesday, February 23, 2010 - link

If you want and SSD that's fast and cheap the agility is hard to beat. If that last bit of performance is important you can buy one of the vertex turbos or an intel drive but it quickly gets un-cheap. Even a 3/4 speed agility is still 10x better than a spinning metal drive.Anand Lal Shimpi - Saturday, February 20, 2010 - link
Hmm, what size drive do you have? I tested the 120GB Agility I believe which has higher read/write specs than the rest.Take care,
Anand

They've admitted that they are building only a limited number of drives, so how will they honor the three year warranty? It's unlikely they will be able to replace a dead drive with another OCZ Vertex Limited Edition, since there won't be any more. Will they replace with an equivalent drive? If so, what would the equivalent drive be?I continue to be skeptical of SandForce's controller technology. I would be interested in seeing some more rigorous testing done on these drives, such as repeated and random simulated power outages during writes, to ensure that the drive doesn't brick itself if power is lost at an inopportune time (especially as this version does not have the supercap).

Typically what they would do is either hold back a percentage of production for warranty replacements. Once they run through these they'd just offer you an equivalent current product.LazerFX - Friday, February 19, 2010 - link
Someone's not read the article...From the "Final Words" page, reproduced here so that anyone else reading the first few pages can get the answer:
"If you’re willing to take the risk, the Vertex LE appears to be the best SSD you can buy at $399. It is a difficult proposition simply because we have had such limited experience with the drive and the controller/firmware have a completely unproven track record. It really boils down to how much of an early adopter you are. At least OCZ as a company tends to take care of its customers, so even if you do take the jump and something does go wrong you won’t be SOL. The Vertex LE will ship with a 3 year warranty and if your drive dies you'll get another LE (OCZ is putting some aside), Vertex 2 or other equivalent in its place.
OCZ’s CEO Ryan Petersen and I could always get into another yelling match if you aren’t taken care of."
So... there you go.

even if they run out of those they put aside. they still have the enterprise versions.bji - Friday, February 19, 2010 - link
Absolutely right, my answer was there and I posted before reading all the way to the end. Mea culpa.
