Would the 4k performance be much lower on sata2?

Yep, write cache enabled.Quote:

I tried all sizes, tested, retested and still landed on the default 128...Quote:

Nothing new but nicely explained.
Vertex 120GB MaxIO edition x 2 Raid 0 16k Stripe
Man these just fly, I had 2 x M4 64GB & guess what? THEY SUCK:ROTF:
OCZ is not rocking Crucial m4 128gb in Pcmark vantage hdd suite.
2xOCZ vertex Max Iops 120gb VS 2x Crucial m4 128gb
OCZ sux :p:
CDM 0-fill and ATTO for benching ssd :rofl: Are you working @ OCZ :bounces:
Heh, also he said he was comparing 120GB V3's to 64GB m4's. Not exactly a fair comparison.Quote:

The latter I can gather from other reviews, but I have yet to see the performance of a V3 120GB MaxIOPS drive by itself -- not in a RAID. The V3 Vanilla has better sequential performance but poorer random performance as compared to the M4 making the comparison difficult. I'm interested to see how the MaxIOPS drive's random R/W performs as that should either make the V3 the superior drive or not.
Correct John, it's not a fair comparison but my 2 x M4 's 64Gb performed poor.Quote:

I also have 3 Mushkin's that rock the 3G controller almost max.
Below are my 3 Mushkin Raid 0 128K & Bottom are running Raid 0 4k
I am in doubt if I should cancel my Vertex 3 IO for a M4
We just need to find a V3 IO 120GB drive review! We already have plenty of them for the m4 128GB so it'll be a matter of comparing.Quote:

New firmware for the V3
OCZ Firmware Release Notes Version 2.06
M a y 1 2 , 2 0 1 1
Issues resolved since version 2.02
*Fixed a rare corner case issue where a STOP error may occur during Windows OS 7 installation on a small number of platforms using Intel’s P67 Sandy bridge chipset
Vertex 3 series, Vertex 3 Max IOPS series, Agility 3 series, Solid 3 series
Note:
1. Future firmware upgrades require drives that have firmware version 2.06 or higher.
2. Once the drive has been upgraded with firmware version 2.06, it can NOT be downgraded to version 2.02.
edit:
A few more lines were added to the resolved list.
-Improved boot up time during typical operation
-Improved the drive’s power consumption when it was in an idle mode
Anymore updates on the V3 MI in a R0 vs the M4 in R0? Too bad there is only 2 x Intel SATA3/6Gbps controller ports. I would love to see a 3 x 128gb or 256GB C300 R0 bench with 4K results..

Hmm seems like something is off about my drives? My sequential speeds seem to be the same as some people's single drive. I have the latest firmware and I seem to get a Intel RST error about the raid array every time I reboot but I reset it to normal and it seems to go back chugging along.
Are you sure that you are using the 6Gb/s ports?
There are only 2 6Gb/s ports on the P67 and so you cant have all 4 SSD's working at full speed simultaneously.
Also, the C300's are running without the WriteBackCache enabled, so they are not really comparable.
Both are great drives though :)

Will be posting some benchmarks on the Agility 3 60GB later today...
I've been playing with the Agility 3 60GB for a few days (since Saturday) and it's been a frustrating experience.
It had the 2.06 FW installed and it is not working very well with the P67, I use it as a spare drive and it is *never* recognized when cold-booting.
Sometimes a "Rescan disks" from Disk Management is what is needed, sometimes I have to reconnect power to get it working.
Everytime it is "discovered" by W7, it installs the driver, never experienced this behavior before.
This never was and still is not a problem with my V3's where all except for 1 is running 2.02, I haven't tried the one that I upgraded to 2.06 but soon will.
Anyways, the Agility 3 60GB is a decent SSD, incompressible data makes a huge impact on performance though, much more than the Vertex 3.
Sequential read using highly compressible data is at ~480MB/s where as incompressible is down to ~165MB/s.
Sequential writes using highly compressible data is at ~450MB/s where as incompressible is down to ~67-70MB/s.
So, based on incompressible it's almost just like using a Vertex 2 60GB (34nm).
It does meet the advertised speeds :)
Attachment 114785
Attachment 114786 Attachment 114787
Attachment 114788 Attachment 114789
(it is 55,9GB, I've just created a smaller partition)
Just for the record, 329.6 MB/s 4K QD32 = 84377 iops.
So, I'll be waiting for the new firmware...
Oh, pro catches :)! I keep forgetting about these small details :doh:. Now they look a ton better:Quote:

Now if I would get around to getting FP for my 9260/8i, I'd be curious how that would do.
