The SSD Update: Vertex Gets Faster, New Indilinx Drives and Intel/MacBook Problems Resolved

Final Words
My recommendation still stands: the Intel X25-M is by far the cream of the crop of the desktop SSD world. The Indilinx based drives have the potential to be good, lower cost alternatives to the Intel drive but you still have to approach them with caution. While the OCZ Vertex drive worked fine in my tests and on my testbed, this is a brand new drive with a controller from a company without a proven track record.
In the coming weeks I will be looking at the latest updates to Samsung’s MLC controller. While I haven’t been terribly impressed with the performance of Samsung drives thus far, they are at least reliable and compatible.
While I’ve heard that the JMicron based drives are no longer selling very well, it looks like at least a few manufacturers are going to be using the JMF602B controllers to deliver 512GB SSDs in the coming months. Buyer beware.
I will say this: outside of Intel, Indilinx appears to know what is important when it comes to SSD performance. With more companies releasing drives based on the Barefoot controller, we should hopefully see any compatibility problems get sorted out faster.
There is some even better news that has surfaced since last week. If the 1275 revision ends up being problem-free, it does deliver more than 3x the random-write performance of the Vertex I first previewed and a more than noticeable 10% boost in application performance. That’s not enough to dethrone Intel, but it is more than enough to make the Vertex even more desirable.
The gotcha still applies: this is the first version of an Indilinx controller we’ve seen in the desktop market. Compatibility and longevity have yet to be proven; so far my experience has been positive but that’s merely one datapoint. We have a long way to go my friends.
I’ll keep you posted.
...and Thanks
I spent a few hours last weekend responding to every single email I received about The SSD Anthology. I've got some recent ones that came in while I was at GDC that I still need to get to. For the first year or so of AnandTech I responded to every single email; it didn’t take too long for me to start getting a few hundred a day and for me to have to curb that a bit in order to actually get work done.
The outpouring of support and appreciation in response to my latest article was too good for me not to respond to every single person. To those of you who wrote me, commented, or just took the time to read the article - thank you.
Your words and support are what inspire me to, even today almost 12 years since I started AnandTech, continue to work on things like The SSD Anthology or The RV770 Story. Thank you.

If Indilinx made the decision to do it off their own bat, OR it is not subject to a subcontracting agreement (that is, doing the firmware exclusively for OCZ), then they are free to offer it to all and sundry.In some industries, even though specific customers pay for changes, they are made available to all customers after a delay period.
It really depends upon who has who over a barrel.

With Anand's huge article and other articles, it's clear that the sequential read/write thoroughput doesn't matter so much - all SSDs, even the notorious JMicron series, can do a good job on that metric. What is relevant to our daily use is the random write rate. Latencies and IOs/second are the most important metric in the realm of SSD.Based on that, I would suggest Anand (and other Tech reporters) to include a real world test of evaluating the Random Write performance for SSD. Because current real-world tests: booting windows, loading games, rendering 3D, etc. they focus on the random read. However, measuring how long it takes to install Windows, Microsoft Visual Studio, or a 4-GB PC Game would thoroughly test the Random Write / Latency performance. I think this is a good complementary of our current testing methodology

They did test that, see the FarCry 2 installation directory at the end of page 6.7Enigma - Thursday, April 2, 2009 - link

I don't know if I missed it in the article, but I didn't notice the reason for the degradation.Is it:
a. Faults in the firmware
b. Faults in the controller
c. Faults in the flash devices themselves, or
d. Progressive increase in the proportion of the SSD blocks that need erasing before rewrite?
To me, it seems that it might be d, especially when using sectors that are small compared to the SSD native block size.
I would be interested to see results for the same tests using 64kB sectors on all drives. For normal files (OS, apps and data), that would increase the space wastage by 8%, but is negligible for multimedia (where the file size is very large compared to the sector size).
I would expect such a change may well produce better overall performance as it would reduce the multiple full block rewrites that result from changes to multiple small files in the same block.
Some rough benchmarking I have done showed a 50% better real world copying of 1GB of files of various sizes between HDD drives compared to using default Vista sector sizes.
If the random write performance is better with larger block sizes, some wastage might be a small price to pay. We have been used to the compromises in using HDDs for so long that compensating for some SSDs downsides should be allowed.
My main interest in using SSDs is for a quiet and cooler Digial Audio Workstation (DAW). I currently have four 150GB WD Raptors making noise and over 40W of heat (requiring more noisy fans). A lot of planning and effort goes into optimising the HDD usage and partitioning.
And now some modern software sampled instruments are hundreds of GB that need fast, responsive storage media. Streaming hundreds of sample streams at once, I would expect HDDs to be spending most of their time seeking. SSDs would seem to be the solution for this, in that they have very short access times, allowing many more accesses per second, coupled with fast read times (to allow getting to the next stream faster). Reading does not seem to have any of the issues giving SSDs bad press.
However, having fast, silent drives for OSs (need multi-boot with one tweaked for audio performance) and projects (which have multiple read streams and simultaneous writes when recording) would complete the quiet profile.

Not to put OCZ down as I wish for them to continue to be a contender and to bring on competition (it's good economics), but...for some reason it just seems like there is a little too much butt-kissing ever since the first article. Granted final points are made, but the first article was so objective and true. If you put out a crap product, then sales should drop. Anand, despite your relations with the manufacturers, if they want to stop sending you products, it's on them.
You can just wait til retail versions to review them, but the truth is the readers are going to side with you and not buy a product they don't know much about.
Tuvok86 - Tuesday, March 31, 2009 - link
yeah I noticed a little butt-kissing going on, but I understand it, since OCZ was totally trashed by Anand regarding the whole Jmicron story so this kind of makes up for it, don't you think?It's good that OCZ recognised its errors and listened to customers and reviewers, and this has to be acknowledged to them
LinkerX - Tuesday, March 31, 2009 - link
I think OCZ does a good job with customer service and PR, which means a lot coming from a small firm. I decided to buy a vertex drive after reading these reviews because it beat up on the raptor.I do not mind firmware upgrades etc... as long as the performance keeps improving.

I am still amazed by your reviews... I just can't ask for more.Keep it from your heart.

very nice, good to see someone slapping intel around a bit, again. intel may be the cream of the crop right now, but at their prices, that cream can just sit out in the sun for all i care.looking forward to see how things change/improve when the real sized drives (500+GB) come out.
