OCZ Vertex 3 Pro Preview: The First SF-2500 SSD
by Anand Lal Shimpi on February 17, 2011 3:01 AM ESTToday: Toshiba 32nm Toggle NAND, Tomorrow: IMFT 25nm
The Vertex 3 Pro sample I received is a drive rated at 200GB with 256GB of NAND on-board. The SF-2682 controller is still an 8-channel architecture and OCZ populates all 8 channels with a total of 16 NAND devices. OCZ selected Toshiba 32nm Toggle Mode MLC NAND for these early Vertex 3 Pro samples however final shipping versions might transition to IMFT 25nm. The consumer version (Vertex 3) will use IMFT 25nm for sure.
Each of the 16 NAND devices on board is 16GB in size. Each package is made up of four die (4GB a piece) and two planes per die (2GB per plane). Page sizes have changed. The older 34nm Intel NAND used a 4KB page size and a 1MB block size. For Toshiba's 32nm Toggle NAND pages are now 8KB and block size remains unchanged. The move to 25nm will finally double block size as well.
Remember from our earlier description of SandForce's architecture that its data redundancy requires a single die's worth of capacity. In this case 4GB of the 256GB of NAND is reserved for data parity and the remaining 66GB is used for block replacement (either cleaning or bad block replacement). The 200GB drive has a 186GB formatted capacity in Windows.
This is a drive with an enterprise focus so the 27.2% spare area is not unusual. You can expect the consumer versions to set aside less spare area, likely at little impact to performance.
The 0.09F supercap, a feature of the enterprise level SF-2500 controller. This won't be present on the client Vertex 3.
The Vertex 3 Pro is still at least a month or two away from shipping so pricing could change, but right now OCZ is estimating sales at between $3.75 and $5.25 per GB. The client focused Vertex 3 will be significantly cheaper - I'd estimate somewhere north (but within range) of what you can currently buy Vertex 2 drives for.
| OCZ Vertex 3 Pro Pricing | |||||
| 100GB | 200GB | 400GB | |||
| MSRP | $525.00 | $775.00 | $1350.00 | ||
| Cost per GB | $5.35/GB | $3.875/GB | $3.375/GB | ||
Both the Vertex 3 and Vertex 3 Pro are expected to be available as early as March, however as always I'd be cautious in jumping on a brand new controller with brand new firmware without giving both some time to mature.

This sounds interestingTrefugl - Thursday, February 17, 2011 - link
Indeed. I'm particularly liking the conclusion:'We're still a couple months away from knowing exactly what to buy, but if you've been putting off that move to an SSD - 2011 may be the year to finally pull the trigger"
That pretty much describes me perfectly. I do have an SSD in my work's workstation, but for home, but I've been holding out for 2011 (IMFT 25nm NAND) and I'm thinking I might not be disappointed by the wait.

Indeed. I'm particularly excited to see what will happen when Intel shows up to the fight.MeanBruce - Friday, February 18, 2011 - link
Intel announced their 510 SSD G3 series today, it will come in 120Gb and 250Gb capacities, SATA3 6Gb/s, read/writes of 470Mb/s and 315Mb/s respect, and will be priced at $280 and $580! It's not using an Intel controller word is Intel doesn't have an in house controller with any real speed! SandForce is really shakin' things up! ;)MrBrownSound - Friday, February 18, 2011 - link
woah, no kidding. I'm looking forward to any reviews of it.MeanBruce - Saturday, February 19, 2011 - link
I knew when Intel pulled their G3 SSD lineup by rescheduling the release it had nothing to do with time constraints and everything to do with the numbers released shortly after by OCZ about their new SandForce controllers, 500/500 read/writes had Intel drawing up an entirely new gameplan for the new G3 lineup! But honestly I thought they would just let a little more magic out of the bag, I had no idea their bag was empty! Now I found out the new 510 series that becomes available March 1st is just going to use a Marvell controller just like the new Crucial and Corsair drives. I still love my X-25M but it's sad when a company with that many resources kicks back on their laurels. Oh well the good news is SandForce is here and with their new client Seagate we will have lots of choices and overall it's just great for the industry at large! Just sucks to watch the one time leader down so low!Out of Box Experience - Saturday, February 19, 2011 - link
Over 50% of the boxes on the Planet still run XPSo, the big question is...
Which one is XP compatible Out of the Box?
I'd love to buy a Sata 3 SSD that can saturate my XP Sata 2 ports but should we stick with Older/Slower Intel Sata 2 SSD's for compatibility??????
Any comment on this issue?

I know everyone has their own reason for keeping XP... but if you want to buy a $200+ SSD how can you not pony up the 100 for windows 7?Besides, 2 more years until XP is officially obsolete...

Bla bla blaHaving Windows 7 does not mean we all need to throw out our XP Licences and all our software that does not run on 7
Why can't somebody just answer my question instead of changing the subject
We get it! You love all the spyware and DRM built into Windows 7 but others don't
So lets just stick to the question I asked shall we?
Which Sata 3 SSDs will be Alignment agnostic at the very least so they can be used on ANY O.S. besides Spyware 7?

Bla bla bla spyware bla drm bla blaYou forgot to mention how locking DX10 to Vista/7 was a deliberate ploy to force gameplayers to upgrade.
And how Win7 is just Vista done right.
Far out some people hold grudges. I was ambivalent about Win7 when it was forced upon me - but for multicore + SSDs you just can't consider an old OS that wasn't designed when they were on the radar.
