SandForce SF-1200 Features

SandForce SF-1200 SSD Processors enable commodity flash memory to reliably operate in cost and power sensitive client computing environments. The SF-1200 is a true single-chip SSD Processor designed for volume manufacturing and outstanding performance. Innovative DuraClass technology delivers world class reliability, endurance, performance and power consumption.

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-1200 has built in AES-128 bit 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-1200 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.

OCZ Vertex 2 SpecificationsOCZ-Vertex-2-Logo-BenchmarkReviews.png

Based on a cutting-edge new architecture, Vertex 2 Solid State Drives raise the bar once again and deliver unprecedented performance for the complete gamut of gaming and professional multimedia applications. OCZ designed the Vertex 2 to surpass the competition where it counts most, pushing the limits in both sequential and random read/write rates. With spectacular performance in 4k file writes up to 50,000 IOPS, these latest drives take productivity to the next level with over ten times the performance of the previous generation. Using the latest controller technology, Vertex 2 not only provides a faster, more responsive PC experience, but promotes cooler, quieter, and more energy efficient conditions compared to traditional mechanical hard drives.

With sheer performance that outpaces the competition, the Vertex 2 doesn't lose sight of what makes an SSD the ideal storage alternative to hard drives and delivers the quality, reliability, and durability demanded by consumers that will not settle for anything but the best. Built with SATA 3Gb/s, the Vertex 2 Series easily integrates into today's mobile and desktop platforms and features TRIM support to optimize performance over the drive's lifespan as the ultimate Windows 7 notebook or desktop upgrade. OCZ Vertex 2 SSDs are available in 50GB to 480GB and come backed by a 3-year warranty and 2 million hour MTBF for ultimate peace of mind.

Recently I had checked back on a year-old SSD review, the Kingston Now V series, then a another older SSD review on a Patriot. And I note a lead article regarding suggested benchmarking specs via SNIA. Only a couple of years into SSDs and the offerings are remarkably better. And of course Intel is going to sharpen the point of the stick by year-end with 25nm flash memory for their newest products. This is without doubt the most rapidly advancing technology for PCs that I can recall. The next five years should be interesting. Looking back from that perspective should be even more eye-popping.

On the chart showing the Intel controller, I think the garbage collection exists for it. I have the M25-V, and it has both a GC tool and has TRIM support.

# Only the latest SSDsOlin Coles 2010-07-14 11:36
Only second-generation Intel SSDs with the latest firmware revision support TRIM and garbage collection (X25-M G2). The other 90% of the SSDs they've sold do not. I will update that chart so future articles will specify support on G2.

# C300 results wrong!?Thomas Bruckschlegel 2010-07-15 11:42
I cannot repro your results, I get ~ 10000 IOPS with your settings: 100% random, 50% write, 50% read, 4KB, 32 outstanding I/O's per target - using the SATA2 interface on my P55 based board.

BTW. iometer is highly affected by compression - I have no troubles reaching ~45000 IOPS with my older Indilinx based SSD on a compressed NTFS partition.

Hello Mr. Bruckschlegel:

I will email you my Iometer configuration file, so that you may reproduce our test exactly as we conduct it. Please be informed that all SSDs are wiped clean using DISKPART "clean all" prior to testing. Also note that this is the total IOPS reported by the test, and not an individual read or write.

There's a major difference between the Marvell SATA-6G controller and the Intel ICH10 on your P55 motherboard. While the Intel ICH10 will likely provide better IOPS results, it won't offer 6.00 GB/s connectivity or speeds. Crucial sent a Marvell controller with the SSD, so our tests have all used their 'recommended' setup.

I tried your file, I had an error in mine "Align I/Os on" was set to "sector boundaries" instead of "4KB" - now I get 20220 total I/Os per second.

Do you think this is totally controller related?
BTW, sanity erase or a format of the whole drive (not a quick format) under win7 with a TRIM enabled AHCI driver+controller will restore the factory performance, not sure if a "diskpart clean all" will do the same.

On the ICH10R tests are you using the Intel driver or Microsoft driver? Should probably clarrify as you can be using the Intel controller with either driver set.

The article already specifies that the Intel RST driver is used, and the tests show the iaStor driver.

# MTTF and MTBF are not the same thingTypoknig 2011-01-03 15:56
Hi Olin, I noticed on your specs page that you listed the this SSDs MTTF as 200,000,000 hours, but everywhere I look OCZ has only published the MTBF numbers. Maybe a typo on your end? This number jumped right out at me because I was surprised to see that this drives MTBF numbers have increased from the 1,500,000 hours MTBF spec of the original 120GB Vertex drives. If you have any inside contacts with OCZ I would very much like to know how they are calculating this number. Of the three original 120GB Vertex drives I purchased in June of 2009 all have failed (at different times), were replaced via RMA, and then proceeded to fail again. In total I have had 7 of the original 120GB Vertex drives in my position, and one just failed again two days ago. Seems to me that OCZ's MTBF numbers are off (and all the failures mentioned by people in various forums seems to support that notion). I should point out though that OCZ has always processed my RMA hassle free, and they are now working with me to take my original drives that I have had so much trouble with and upgrade me to something a bit more stable. I really appreciate them standing by their product, and I hope they can work out the kinks in their line of SSD products soon.

Hello:

Thank you for bringing this to our attention. These specification are pulled directly from the manufacturer-supplied data sheet, and are often subject to change without notice. I would consider the specifications listed on the website to be the most current and accurate.
