We reported on Intel's SSD 330 weeks ago, but today is the official announcement of the drive and its availability in the channel. Unlike previous 300 series drives, the 330 isn't based on Intel's own controller - it's the second SandForce SF-2281 drive in Intel's lineup.

Read on for our full analysis of the announcement.

With OCZ intent on moving as much volume to its in-house Indilinx controllers as possible, SandForce (now LSI) needed to expand to additional partners. OCZ has strong control over the channel so SandForce needed to turn to multiple partners to diversify its portfolio. One key win for SandForce was Kingston. We saw the launch of the first Kingston SandForce (SF-2281) based drive last year under the HyperX brand. Today Kingston is announcing a lower cost version of the drive with the HyperX 3K.

The 3K in this case refers to the number of program/erase cycles the NAND inside the SSD is rated for. Read on for our full review.

Intel was rumored to be working on a SandForce based drive for several months now, but even the rumors couldn't encapsulate just how long Intel and SF has worked on this drive. According to Intel, the relationship began 1.5 years ago. Still lacking a 6Gbps controller of their own and wanting to remain competitive with the rest of the market, Intel approached SandForce about building a drive based on the (at the time) unreleased SF-2281 controller. Roughly six months later, initial testing and validation began on the drive. That's right, around the time that OCZ was previewing the first Vertex 3 Pro, Intel was just beginning its extensive validation process.

Codenamed Cherryville, Intel's SSD 520 would go through a full year of validation before Intel would sign off on the drive for release. In fact, it was some unresolved issues that cropped up during Intel's validation that pushed Cherryville back from the late 2011 release to today.

Intel's strenuous validation will eventually make SandForce's drives better for everyone, but for now the Cherryville firmware remains exclusive. Intel wouldn't go on record with details of its arrangement with SandForce, but from what I've managed to piece together the Intel Cherryville firmware is exclusive for a limited period of time. That exclusivity agreement likely expires sometime after the SF-2281 is replaced by a 3rd generation controller. There are some loopholes that allow SandForce to port bug fixes to general partner firmware but the specific terms aren't public information. The important takeaway is anything fixed in Intel's firmware isn't necessarily going to be fixed in other SF-2281 based drives in the near term. This is an important distinction because although Cherryville performs very similarly to other SF-2281 drives, it should be more reliable.

It's a depressing time to be covering the consumer SSD market. Although performance is higher than it has ever been, we're still seeing far too many compatibility and reliability issues from all of the major players. Intel used to be our safe haven, but even the extra reliable Intel SSD 320 is plagued by a firmware bug that may crop up unexpectedly, limiting your drive's capacity to only 8MB. Then there are the infamous BSOD issues that affect SandForce SF-2281 drives like the OCZ Vertex 3 or the Corsair Force 3. Despite OCZ and SandForce believing they were on to the root cause of the problem several weeks ago, there are still reports of issues. I've even been able to duplicate the issue internally.

It's been three years since the introduction of the X25-M and SSD reliability is still an issue, but why?

Read on for a current state of the union on SandForce SSDs as well as a discussion of SSD reliability in general.

Although consumer SSDs are far from a mature technology, PCIe SSDs are even further behind on the growth curve. The upside is huge. As SandForce has already demonstrated with the right dataset a single SSD can nearly saturate the 6Gbps SATA bus. Rather than force OEMs into putting yet another very high bandwidth bus on the motherboard, SSD vendors everywhere (Intel included) turn their attention to PCIe as a solution to the problem.

The holy grail is a native PCIe solution. Recently Micron announced such a thing: the P320h. However the estimated price tag on the P320h could be in the $5000 - $10000 range depending on capacity.

Manufacturers in the consumer SSD space are attracted to PCIe solutions simply because margins are higher. For the most part, client storage is a commodity and if you don't make the NAND and controller going into an SSD you're not making a ton of money selling drives to end users. Sell to an enterprise customer and all of the sudden a couple thousand dollars per drive seems like a bargain.

OCZ started making PCIe SSDs the simplest way possible. Take a couple of SSDs, put them on a single PCB behind an on-board RAID controller and you're good to go. The single card performance was decent but of course there were issues. A single controller failure would take out the whole drive and things like TRIM weren't supported either.

Recently OCZ has been trying very hard to be more than just a rebrander of components. The acquisition of Indilinx puts a wedge between OCZ and a lot of its former peers in the memory business, but it's still a far cry from Intel or Samsung. Its latest PCIe SSD is another step in the maturing of the company. This is the RevoDrive 3 X2:

Not wanting to be completely married to Intel NAND production, OCZ wanted to introduce a version of the Vertex 3 that used 32nm Toshiba Toggle NAND - similar to what was used in the beta Vertex 3 Pro we previewed a few months ago. Rather than call the new drive a Vertex 3 with a slightly different model number, OCZ opted for a more pronounced suffix: MAX IOPS. By using 32nm NAND OCZ gets more die per channel and thus can get better performance through interleaving.

Not wanting to be outdone, Patriot's first SF-2281 SSD uses the same 32nm Toshiba NAND as the Vertex 3 MAX IOPS. These two drives are the new face for high performance SandForce SSDs. Read on for our full review!

OCZ has been at the forefront of each generation of SandForce SSD release since the debut of the SF-1500 based Vertex Limited Edition. More recently the Vertex 3 was the first client SSD to use SandForce's SF-2281 controller. Many of you have written me asking if the Vertex 3 is worth the additional cost over the Vertex 2. Given that you can pick up a 120GB Vertex 2 for $210 ($180 after rebate), and a 120GB Vertex 3 will set you back $300 flat it's tough to recommend the latter despite the performance improvements. If you don't have a 6Gbps platform (e.g. Intel 6-series, AMD 8-series) the Vertex 2 vs. Vertex 3 decision is a little easier to make, otherwise the newer, faster Vertex 3 is quite tempting.

There's another issue holding users back from the Vertex 3: capacity. The Vertex 3 is available in 120, 240 and 480GB versions, there is no 60GB model. If you're on a budget or like to plan frequent but rational upgrades, the Vertex 3 can be a tough sell.

Enter the Agility 3, OCZ's mainstream SF-2281 drive.
