The OCZ Vertex 3 Thread

Hmm, not convinced with ATTO. It gives read speeds with my X25M Raid array that's well beyond 100% improvement over one drive. 650MB/s? I wish! I think I'll believe the AS SSD results from these Vertex3 drives.

Definitely wouldn't get one to replace the RAID array on an X58, might get a pair of Vertex2Es though. 160gb for less cash than a 120gb V3 and over 500/500 on the intel SATA2 controller. No TRIM hasn't been a problem at all, still getting 430/150 after 2 months usage.

Not sure about that issue with SecureErase, I've been using HDDerase? Might be a consideration.
 
ATTO = compressible, AS-SSD = incompressible.

Vertex 2/3 compress data before writing so perform better with compressible data, hence the discrepancy. OCZ reckon 80% of OS drive writes are compressible.

They would say that!

Seriously though, as that is irrelevant to read speeds I'd still say ATTO is not trustworthy. AS SSD and CDM look much more realistic and shows that these drives may not be what they are advertised to be, especially on the Marvell controller. What I would really like to do is create an MKV, from two files on the disk, to see how fast that is.

HDDerase is a program that sends a SecureErase command to the SSD haha.

Right, I thought it sounded familiar.

Which is why you get much higher reads than writes on AS-SSD. ATTO is the correct way to bench these drives.
 
So people keep saying, but no-one has explained why.

From what I can tell from their forums, it's just because ATTO uses a particular method of writing that suits their drives (they use write compression on the fly to increase NAND life) and because they know that writing lots of incompressible data to their drives is much slower and because the SF controller throttles write speeds when it sees this happening.

Also, it's because OCZ tell you to use a particular app for benching. They also tell you not to install their drives in an overclocked system, which pretty much says it all really. :p

What I would like to know is how to differentiate between what is compressible and what is incompressible data because if I am likely to do more writes that are incompressible then I may choose a different controller. That's assuming that they don't have similar issues! :rolleyes:

edit; interestingly found this in the bit-tech review

the Vertex 3 in our systems this week and found that its speeds err more towards those in AS SSD rather than ATTO in general use. When copying programs, music and videos, we saw the drive’s write speeds peak at 220MB/sec rather than the 500MB/sec seen in ATTO

You can use any benchmark you like, they'll each show you different performance for different scenarios. However, doing anything other than ATTO will contribute to the drive slowing down over time, because the drive throttles when you do a lot of incompressible writing.

If you're gonna be writing a lot of video and audio to the SSD, don't get a Vertex 2/3.
 
That's pretty much what I was thinking. It's good to consider all of the benchmarks because it gives you the best and worst case scenarios.
 
Hey :D Benchmarks are all well and good but Im wondering if there is any real world performance boost compared to something like an Agility? Thanks :)
 
Sorry to drag this a little off-topic here, but how are these going to compare to the new Crucial M4's. Im pretty new to SSD's and looking to invest.The benchmarks say theyre pretty similar, but each beats the other in different tests, cant quite distinguish what difference that would make to end user.

I have upgraded from a C300 64GB and to be honest I can't tell the difference in W7. Upgrading from a mechanical drive will be like night and day however just like CPU's etc there will be a tipping point when it will be difficult to tell the difference between one drive and another.
 
Thats kind of what i expected really just fairly new to it.
I presume if i were to put OS on the it would only really boost the OS speed and not anything on the mechanical drive? So 256gb would be my best bet ( I have a lot of stuff!)
Back on topic, i might invest in one of these!
 
So has anyone taken the plunge and tested one of these on a x58 yet? Or will i be the first this weekend? Figure i should have a better chance than most as i will be plugging it into a G1 Assassin which has extra lanes connected to the marvell controller (or so i read).....

nervous and a little sick about the impending install/test session this weekend is sure to become.

I replaced my raid on my X58 from HDD to single SSD and now i am on RAIDED SSD Vertex 3. On X58 i would say it is worth going vertex 3 if you plan to upgrade or change within a year or so (which i plan on doing). If i was not upgrading and happy with what i had i would go for larger Vertex 2's

Which controller are you running the raided V3's on? Some benches would be nice. :)

Interestingly, I was looking at some reviews last night of the V3 comparing it to the other top SSDs and it is still very very good at incompressible writes, so I'm not too concerned about that now.

The intel one, but you still won't get full speed from it. This review shows the performance on an SATA 3Gb/s vs SATA 6Gb/s.

See above review. The V3 is faster in pretty much all scenarios.
