Retailers may go above MSRP due to expected demand

OCZ has stated before that it delayed its Vertex drives due to firmware upgrades. DailyTech has now learned more details on why OCZ held back shipments of its flagship SSD drives.

The latest firmware for OCZ's Vertex series boosts sequential read and write performance, so much so that it can compete with Intel's X-25E Extreme series on performance. However, the Vertex boasts a much greater capacity and a much lower price.

The Vertex series, which uses an Indilinx Barefoot SSD controller, was originally specified at 200MB/s sequential read and 160MB/s sequential write. However, OCZ's internal tests show up to 250MB/s sequential read and 240MB/s sequential write speeds.

These tests were conducted on an empty drive, and will not officially be presented to consumers. However, it gives an indication of how fast the final drives will be and allows some results to be inferred.

While the firmware is responsible for a large part of the improved performance over the introductory specifications, it is only because of the hardware that it is able to work with. The 120GB and 250GB drives have 64MB of DRAM cache and more channels to access its MLC NAND flash, whereas the 30GB and 60GB drives only have 32MB of cache.

It should be noted that OCZ rounds down its capacities for several reasons. Most storage vendors show capacity in decimal format, whereas Windows show capacity in binary format. This means that the reported capacity is lower than what is on the label.

Most SSDs also reserve some capacity for redundancy in case of bad sectors, and also for wear leveling. These reserved areas may occupy up to five percent of an SSD's storage capacity.

Prices are also coming down, as more production of 16Gb and 32Gb NAND flash comes online at smaller process geometries.

OCZ will post official specifications and revised MSRPs when it ships the Vertex series later this month.

RE: Performance Degradation over time

Unless you going to do some database were you going to have tons of random writes, noting beats a high performance SSD.

"We need a optimized SSD file system and OS too"

Yes, if this is implemented, it will give SSD's a even greater speed gain over HDD, a specially if this is done when the SSD is idle(*).
But SSD optimization will be implemented in Win7.
(*)idle optimization, data is written on other part of the SSD and later, the removed data blocks will be purged by writing zeros to them, there was something about that on the Win7 blog but properly wouldn't be ready before SP1

About 80-90% of you HD actions are read actions, properly even higher for most games!

I use a X25-E as my OS / C: drive.
2x Transcend 16GB in RAID0 on a *cheap* "Areca ARC-1200" whit 128MB cache HD controller for the games i am playing on the moment.
(The cache mem helps buffering writes, so unless the file is bigger then the controller and HDD cache combined i have no problems whit slow writes)
And a 300GB raptor for my swapfile and the rest of my files/games/programs.
No one beats my setup when it comes to HD speed/game load times.
(at least no one I know ;-) http://www.hardware.info/nl-NL/usersys/cmxxZ51hk2m...

By splitting up my main data streams i win a lot of extra speed, but even a single latest gen SSD will let a 300GB Raptor eat dust by a factor of 3 to 8 in most real-world benchmarks (except random write database benchmarks)

Boat Launch & Storage Mark 2008 Index imho the most importance bench as it resembles real life usages (Google translation from dutch)
http://64.233.183.101/translate_c?hl=en&langpair=a...

About 300 different HD Benchmarks in dutch but the Nr's talk for them self.

For the gamers under us that wane use a SSD just for games here is all you need to know!
http://tweakers.net/benchdb/suite/33

Here you can see what a good controller can do (Intel ICH7R)
http://tweakers.net/benchdb/test/164

Here you can see what extra cash mem dose 250% gain whit 2GB over 256MB
http://tweakers.net/benchdb/test/153

Using the filter on the pages in the links, will make it easier to do A apples to apples comparison


PS. adding a SSD will have not mouths benefits if you don't have at least 4GB system mem, as you have to use the swap-file way to mouths if you only have 2 ore even less mem in your PC.
