Benchmark Results: 4 KB And 512 KB Random Writes

OCZ's Vertex 3 Pro: Second-Gen SandForce Perf Preview
By

SandForce's second-generation controller helps OCZ skip to the front of the line. OCZ said 70 000 IOPs in 4 KB random writes, and we got 70 000. It's hard not to be impressed by this chart.

Both the Vertex 2 and Agility 2 use the SF-1200. The difference between them is that the Agility 2 uses SandForce's mass production firmware. The Vertex 2 drive, in comparison, uses OCZ's optimized "extended" firmware. 

Writing completely random data to these drives represents a worst-case scenario for the first generation of SandForce drives. When we rerun our benchmarks, the values widely differ from run to run, despite performing a secure erase. This isn't the case with the Vertex 3 Pro. We are seeing fairly consistent scores across the board, and when we look at largely concurrent operations, the drive excels. With a queue depth of 32, it achieves roughly 300% speed increase from what we saw with the Vertex 2.

    Erm... Semiconductor?

    2$ a GB is still too high for me, i have a 2tb and a 1tb hdd in my computer, i really want to move to ssd's but i cant afford it, at the moment with not a lot on my c partition im using 200GB thats 400$ and i wouldnt be happy with less than a 400gb system partion which is 800$

    I've been running SSD for a couple of years and you don't need a 400GB system partition. I've run on a 60GB system partition before, and yes that was a bit on the tight side. 120GB is probably a good balance between capacity and cost, but if you can afford it 240GB (what I have now) is enough for the OS, applications, the photo's I'm currently working on and a couple of VM's.

    Most of your 'stuff' doesn't get accessed anyway, just run Treesize and look at the last access date for your data. Look at the size of everything that was accessed in the last month, and this is a good sizing estimate for SSD - obviously leave a bit of overhead for OS components that aren't always used and for growth. Everything else can go on a much cheaper HDD. I guess we all got lazy when 1TB and 2TB disks came out, SSD makes you think about data management again, but the rewards are worth it.

    Ok but $500 for 100 Gb is too much.

    True, they aren't cheap, can't argue that one.

    actually when i say that i need 400gb partition im including just my games and programs, i would need at least that for peace of mind, actually at moment im only using 200gb of it but i wont a bit of headroom

    Do a quick scan with treesize mate, you won't need to spend as much as you think.

    My system disk is only 80GB (HDD sadly) and has 33GB free. I don't see an 80GB system disk as being too limiting, although I would shy away from 60GB

    I've been on an 80gb system disk (hdd) for some time now, and with windows and other programs that have to be on the os drive that leaves me with only about 40gb of free space to do with as i like. 40gb is enough for maybe 4 games at a time if I'm lucky, and even so that means doing a *lot* of uninstalls and reinstalls while leaving the drive almost at capacity all the time, which wouldn't be good for a ssd.
    A ssd much smaller than 100 gb just wouldn't be practical for anything much but the os, and any larger than 100 gb and prices go through the roof. I'm sure theres benefits to be had with ssds, but affordable ones aren't all that much better than fast hdds and just dont have enough space...

    I don't know what you lot are talking about - I've been running my os (vista and win7) on a 30gb vertex and it great. Programs and storage are on an HDD.

    The Vertex range is for sure the staple of the ssd market and OCZ customer service on their forums is by far the best I have ever seen
