SandForce SF-2200 Features

Endurance and Longevity
As each generation of flash memory evolves and the silicon geometries shrink - performance, reliability, endurance, and data retention are negatively impacted. DuraWrite technology extends the life of the SSD over conventional controllers, by optimizing writes to the flash memory and delivering a write amplification below 1, without complex DRAM caching requirements.

Performance and Power Optimization
SSDs are capable of significantly outperforming traditional HDDs, but typical controllers haven't delivered the compelling value necessary for mainstream adoption. SandForce DuraClass technology enables the SSD to maximize both the endurance and performance for the life of the drive fulfilling the promise of high speed flash memory in client computing applications and improving system performance by up to 50% as measured by the SYSmark Benchmark.

Mobile Computing Security
The SF-2200 series has built in AES-256 bit double encryption controllable by a configurable user password. This feature prevents would-be thieves from extracting data directly from the flash memory should they ever have access to the drive.

Data Protection and Reliability
SF-2200 SSD Processors provide up to 100x greater data protection than today's SSDs, and leading enterprise HDDs. This is a result of superior ECC protection and unique RAISE (Redundant Array of Independent Silicon Elements) technology. RAISE provides the protection and reliability of RAID on a single drive without the significant write overhead.

Compare the prices and warranty between these two models, as everything else is nearly the same.

What happened to HG3 drives?

I'm disappointed by several things in this review.
First, the comparison of a OWC 120GB drive to OCZ's 240GB drives.
In this class 240GB drives are always faster.

Second, by not testing (or mentioning) the OWC extreme6, you completely missed that it now uses a different Sandforce controller! It uses the 2282, and is (as of now) the only drive to do so.
From your SandForce SF-2000 Series SSD Processor Overview:
"High-IO consumer systems will be well suited for the flagship consumer SSD processor: SF-2282. The SandForce SD-2282 is virtually an eight-channel/sixteen lane enterprise drive with MLC NAND, and won't be produced in the same quantities as other controllers."

What a shame to miss such a useful and helpful opportunity.

Explain to me how I am to compare other products OWC chooses not to send us, and compare against capacities that aren't offered to us? You seem to know how this should be done better than we do, so please explain how to overcome these obstacles.

Had OWC offer other products or capacities, we'd use them. Besides, the difference would be less than 5% max.

Wow, I wasn't attacking, just explaining my disappointment as I have both drives.

As OWC seems to be a very customer friendly small shop, maybe you could just ask your contact?
This is a potential major difference in hardware, as your site had highlighted in your SandForce Processor Overview.
Kudos on even having that bye the way.
Hadn't seen that elsewhere, even the SandForce site.

I'm like many, who need experts to help find the differences.

Opps...

I refer to the OWC 240GB and 480GB extreme6 drives with a "-T" part number as using the 2282 controller.

The OWC 120GB extreme6 drives with a "T" part number suffix still use the 2281, as you state in the review.

I should also mention that I have both a OCZ 120GB max IOPS, a OWC 120GB extreme6, and a pair of OWC 240 extreme6 drives.

I cloned my old HD (with Intel RST 10.6) onto all four drives and ran AS SSD benches, which I'll post later.
In brief OCZ 120 max IOPS was slowest, OWC 120GB extreme6 was quite a bit faster, and a OWC 240 extreme6 flat blew the others away.
Mind, this was just a quick test of just my drive set-up, but every thing was at least equal.

Come on now. If you read any number of SSD review you should know that we ensure these drives are as apples-to-apples as possible, and that to test fairly each SSD must have NAND in the exact same condition (normally clean/SE) and benchmarked as secondary drives. A cursory test won't tell you very much on SSDs because the NAND condition changes performance so dramatically.

I never intended to infer that you didn't test fairly or well.
I just took the SSDs as shipped, cloned a HD and ran a canned test.

My results were:
OCZ 120GB Vertex 3 MI Overall = 356

OWC 120GB Mercury Extreme6 Overall = 373

OWC 240GB Mercury Extreme6 Overall = 489

Is that much of a difference that I might notice in doing video transcoding?
Thanks

Video transcoding is a very BAD test to compare storage devices. It depends primarily on CPU/RAM/GPU, and have almost no relative need for storage performance. If you want to run a test, try ATTO Disk Benchmark. It's free, and very easy to understand. You can even match to our test settings in a few clicks.
