Sorry no, but I've seen 30 MB/s plus for 4K RR. This is one of the fastest drives I have played with.
For now M5P's been a let down for me, not much improvements over M3P.. I was expecting ~40MB/s 4K reads, waiting for more reviews for clearer opinion..
I have to run, I have youth football to coach tonight but you can find the TRIM / fill testing info here:Quote:

Also, as I said in the review, this drive has something going on with TRIM but I'm not sure what it is yet. There was an NDA launch and the drive just arrived at 3PM the day before. It's not my best article for sure but I've been working the drive all morning to get some of the other details worked out.
So the drive is 75% full. You then delete all the files and re-run the benchmark? If so how long are you waiting between deleting the files and starting the benchmark? If you run it straight away try waiting for two minutes or so. You should find performance has bounced right back to new.Quote:

That's not the M5 Pro.
Right. It appears to have Micron flash and the 9174 controller. Probably the M5S.Quote:

The fact that the drive arrived just before the NDA is your problem because it's your choice to publish the review at the NDA date and not a day or two after ;-)Quote:

It is good to know that you are testing the M5P. behardware's SSD test results are always interesting to see, especially the tests where you fill the SSDs with data and stress them before measuring sequential and random write speeds. I'll be looking forward to seeing the M5P results on behardware!Quote:

I've seen lots of weird results on the Vertex 4. Even just looking at AS-SSD results with fw1.5 that are posted on the internet, it seems that the sequential read speed can vary from low 400MB/s up to 520MB/s. And most of those are (I assume) with a nearly empty SSD. It seems like the V4 firmware likes to do some really aggressive housekeeping at random times, and this can affect the performance measured.Quote:

I guess the V4 is just "twitchy".
+1...Ocz still has some work to do regarding V4 FW imo. There's a good chance that the majority of their FW engineers are up to their eyeballs with Ocz's first in-house (and very promising) controller...the Indilinx Barefoot 3. Looking forward to a review that thoroughly compares the marvell based V4 to the M5P.
Any more info on the M5P? Plextor made an announcement and there hasn't been anything since as far as availability and reviews besides the TT review. Paper launch?
What else do you need to know specifically?Quote:

Plextor might be a bit slow with initial production if the 19nm tosh toggle hasn't ramped up sufficiently...just a guess tho.
Paper launch? I think not, you can find them in any computer shop here in Japan.Quote:

I have data that says different and even know why TRIM isn't running at 100%. I guess you'll have to wait for the follow up article.Quote:

I wouldn't be surprised if we don't see 20nm until 2013....but they are still saying 2012 as of right now.
