The Bright Side: The Vertex is Nearly 3x as Fast
Immediately after I published the anthology, I asked OCZ for a shipping version of the drive. I wanted final hardware, updated firmware, shrink wrap, the whole 9 yards. Here’s what I got:
The drive itself looked identical to the first Vertex I tested, but the differences were all internal. The new drive used a new PCB layout, let’s pop the top off to see it:
Oooh.
The major change on the new board layout is the addition of a 2-pin jumper on the back of the drive to allow the drive’s firmware to be updated by the end user. OCZ tells me that as of 1275, the jumper is no longer needed to update the firmware so it looks like it was a short lived change.
While OCZ claims that there’s significant validation done on each firmware revision, without a doubt it’s significantly less than what every Intel and Samsung drive goes through. There’s a certain amount of risk you take when jumping on the unproven hardware bandwagon, so as always proceed with caution. It’s worth looking into
While I haven’t done much testing on 1275, I can’t blame you if you want to try the firmware out right away because it is good.
I’ll start with the best news first. I looked at 4KB random write performance once again using iometer. This test is the same one I used in last week’s review; a 3 minute run, 3 outstanding IOs, 4KB random writes spread out over an 8GB section of LBAs. I filled the drive completely before running the test.
| Random Write (4KB Block, 3 IOs) | IOPS | Transfer Rate | Average Latency (ms) |
| Intel X25-M | 5923 | 23.1 MB/s | 0.51 ms |
| OCZ Vertex 1275 | 1656 | 6.47 MB/s | 1.81 ms |
| OCZ Vertex 0112 | 617 | 2.41 MB/s | 4.86 ms |
Yeah. It’s fast. Not quite as fast as Intel’s X25-M but it’s good. Average latency has dropped quite a bit. The Vertex using firmware 1275 performs used at about the level that the original firmware performed brand new. The Intel drive can still crunch through over 3.5x the number of IOs per second as the Vertex, but it also costs nearly 2x per GB. The Vertex proves itself an interesting value alternative.
I then looked at random read performance. Now most SSDs do just fine here, even the JMicron based ones.
| Random Read (4KB Block, 3 IOs) | IOPS | Transfer Rate | Average Latency (ms) |
| Intel X25-M | 13883 | 54.2 MB/s | 0.22 ms |
| OCZ Vertex 1275 | 8931 | 34.9 MB/s | 0.34 ms |
| OCZ Vertex 0112 | 8184 | 32.0 MB/s | 0.37 ms |
The new firmware bumped up the Vertex’s performance by about 9%.
I spoke briefly with one of OCZ’s flash engineers and it seems like the reason the 1275 firmware is so much faster in random write speed is because of a bug in the 0112 firmware I tested with. There was apparently a problem with the 0112 firmware that prevented the controller from writing to as many flash devices as possible in parallel. The 1199 firmware fixed this, which explains why the sudden rush to ship the firmware. Unfortunately it looks like that version also has problems and thus we end up back at square one again. There’s no free lunch folks.
Sequential read performance showed a very marginal performance improvement:
| Sequential Read (2MB Block, 1 IO) | IOPS | Transfer Rate | Average Latency (ms) |
| Intel X25-M | 115.1 | 230.2 MB/s | 8.7 ms |
| OCZ Vertex 1275 | 127.9 | 255.9 MB/s | 7.8 ms |
| OCZ Vertex 0112 | 125.1 | 250.1 MB/s | 8.0 ms |
But sequential write performance went up tremendously:
| Sequential Write (2MB Block, 1 IO) | IOPS | Transfer Rate | Average Latency (ms) |
| Intel X25-M | 35.5 | 71 MB/s | 28.2 ms |
| OCZ Vertex 1275 | 67.7 | 135.3 MB/s | 14.8 ms |
| OCZ Vertex 0112 | 46.7 | 93.4 MB/s | 21.4 ms |
The Indilinx (and most other) drives offer better sequential read/write speed than the X25-M. Intel optimized for the most important characteristics for a desktop: random read/write performance, while most other manufacturers optimized for sequential read/write. Indilinx is the first to seem to want to really drive sequential without completely forgetting about random performance.

Thanks SO MUCH for your update on the who SSD situation. Things seem to be looking up! Great Job. Keep em coming! :Dzonteck - Monday, March 30, 2009 - link
yes i have to agree, this updating on the ssd situation has been invaluable to me too. you hear good things on the forums about the new firmwares and it's so good to see you share how things have changed even since last week.Mastakilla - Monday, March 30, 2009 - link
Hi!Great article once more!!
Looking at the price / performance ratio of the Intel and Vertex does leave 1 interesting question open:
how does a RAID 0 of Vertex drives compare to a single Intel (in price it is about the same)
Also interesting to invest is the compability between SSDs and RAID controllers (I have read about issues between non-Intel SSDs and the Intel based RAID controllers (like most Arecas))
Keep up the good work!

Should destroy the Intel drive in all real-world tests. All it takes is to look at a single Vertex drive with the new firmware to see it is within ~1 second load time, and already significantly faster with copying larger files. Honestly, Intel should be scared to death of this bugger, or else they realize they milked the teat for as long as possible without competition, and can now drop the price inline with OCZ and Supertalent.Hauk - Monday, March 30, 2009 - link
Some two weeks ago I reports that Super Talent had an Indilinix based drive on the market. Was surprised at the lack of information. Nice to finally see details surfacing. A product with such potential has been poorly marketed to this point in my opinion.Props to OCZ for their work in getting Vertex up to speed. Many have been critical that they rushed the product to market. Yea it sucks that flashing destroys data; but look at mobo manufacturers. We should be used to bug fixes through firmware updates. Intel needed some form of competition.. good for everyone.
I flashed my Vertex 60GB to 1275 without issue. It's a simple process. Would like to see instructions on something other than a forum post however. How about a .pdf to accompany the files..

Nice!Nickel020 - Monday, March 30, 2009 - link
Thanks for the update!One thing I missed in your articles though is alignment and its importance for performance. The drives ship with a partition on it and it's supposed to be aligned, but the partition on my drive seems to be off, as I only got about 195/75 MB/s read/write max on ATTO when it was "new" and like 105/35 MB/s now that it is "used". I have yet to re-install the drive and properly align it, but either I have a defective drive or this is caused by alignment, making proper alignment extremely important. I'm on the 0122 FW btw.
Another thing I missed is RAID1, you do not mention it at all. You can basically get 2 Super Talent 60GB drives for the price of an Intel 80GB and use them in RAID1. This will still have lower random 4KB performance, but the increased performance in many other areas should be dramatically higher than the Intel's.
I have never used RAID1 though, but I would love to hear your opinion on this, as I'm considering getting a second 60GB OCZ.
Nickel020 - Monday, March 30, 2009 - link
I meant RAID0 of course, that stuff always gets me confused...Shinshin - Monday, March 30, 2009 - link
Seems that the speed is limited by the chip as stated in their website 230MB/s read and 170MB/s write.I'm looking forward their next-gen chip which will support sata v3 and will have 500MB/s throughput (!) by the end of 2009.
(btw, they have a great website IMO...)
