The SSD Anthology: Understanding SSDs and New Drives from OCZ

OCZ Sends Me SSDs, Once More
As I mentioned before, after the X25-M article I was somewhat blacklisted from getting more SSDs to test. Since the Core V2, I hadn’t tested a single SSD from OCZ or anyone else for that matter. Everything on the market was either based on Samsung’s SLC drive, JMicron MLC or the Intel X25 series.
Needless to say, I was excited when I got a box from OCZ.
I got the drives early in the morning. Excited, I opened them up. Inside the box were three drives. The OCZ Apex (I’d never reviewed it, and OCZ reluctantly sent another JMicron drive to me), the Vertex and the Summit.
The Summit was based on Samsung’s latest MLC SSD controller, which I’d heard great things about. It’s supposed to compete with Intel’s drive.
The Vertex is the drive I was most interested in. A value SSD that didn’t suck, or at least that’s what it seemed to be on paper. Ryan even left me a little note on the box:
O RLY?
It’s worth noting that although other SSD makers will be making drives based on the Indilinx and Samsung controllers, OCZ was the first to get me drives based on both of these controllers. In fact, I was done testing the OCZ Summit based on Samsung’s latest controller before Samsung ever offered to ship me the drive.
I pushed the Apex and Summit drives aside for now. What I wanted to know was how the Vertex performed.
I cloned my system drive and used the Vertex in my personal machine. As soon as I hit the desktop I knew there was a problem; all of my icons took longer than they should’ve to load. It took about 30 minutes of actual usage for the drive to stutter and within a couple of hours performance got so unbearable that I had to pull it out.
Sigh, the Vertex was broken.

I understand your point, but I am not sure you understand the point I (and others) are trying to make. The SSD makers (should) know their market. As they seem to be marketing these SSDs to consumers, they should know that means the vast majority are on Vista or OSX, so the OS won't be optimized for SSDs. It also means the majority will be using integrated disk controllers. Therefore, in choosing a SSD controller which does not operate properly given those restrictions, they chose poorly. The testing here at Anandtech shows that regardless of how the drives might perform in ideal circumstances, they have noticeable issues when used the way most users would use them, which is really all those users care about.tshen83 - Thursday, March 19, 2009 - link
In the history of computing, it was always the case that software compensated for the new hardware, not the other way around. When new hardware comes out that obsoletes current generation of software, new software will be written to take advantage of the new hardware.Think of it this way: you always write newer version of drivers to drive the newest GPUs. When is the last time newer GPUs work with older drivers?
Nobody should be designing hardware now that makes DOS run fast right? All file systems (except ZFS and soon BTRFS) are obsolete now for SSDs, so we write new file systems. I am not sure Intel X25-M's approach of virtualizing flash to the likings of NTFS and EXT3 is the correct one. It is simply a bridge to get to the next solution.
SSD makers right now are making a serious mistake pushing SSDs down consumer's throats during an economic crisis. They should have focused on the enterprise market, targeting DB servers. But in that space, Intel X25-E sits alone without competition. (Supertalent UltraDrive LEs should be within 25% of X25-E by my estimation)

Now I understand what you meant in the beginning. But still I don't agree with you, the system reviewed is the one 99% of SSD buyers will use(integrated mobo controller + NTFS). So, why optimize the benchmark to show the bad drives in a good light?About the Vertex, I don't understand what you are complaining about. After reading this article most people got the idea that Vertex is a good drive and at half Intel's price (I know, I searched on google for comments about this article).

Professional people only look at two SSD benchmarks: random read IOPS at 4k and random write IOPS at 4k(Maybe 8K too for native DB pages).The Vertex random write IOPS at 4K size is abysmal. 2.4MB/sec at 4K means it only does 600ish random write IOPs. Something was wrong, and Vista/ICH10R didn't help. The 8GB/sec write boundary Anand imposed on the random write IOPS test is fishy. So is the artificial io queue depth = 3.
The vertex random write IOPS should be better. The random read IOPS also should be slightly better. I have seen OCZ's own benchmark placing the Vertex very close to Intel X25-M at random read/ write IOPS tests.
I personally think that if you use NTFS, just ignore the SSDs for now until Windows 7 RTM. You can't hurt waiting for SSD price to drop some more in the next 6 months. Same thing for Linux, although I would argue that Linux is even in a worse position for SSDs right now than windows 7. EXT3/EXT4/JFS/XFS/REISERFS all suck on SSDs.

Anandtech should adopt the same comment system as Dailytech so that comments that don't make any sense can be rated down. Who would want to read a review of something using a beta OS, or worse an OS that is only used on servers? I think it would be interesting to see if Windows 7 beta offered any improvements, but that should not be the focus of the review.7Enigma - Thursday, March 19, 2009 - link
Here's another vote for the Dailytech comments section. The ability to rate up down, but more importantly HIDE the comments below a threshold would make for much more enjoyable reading.curtisfong - Wednesday, March 18, 2009 - link
Why should Anand test with Windows 7b or *nix? What is the majority OS?Kudos to Anand for testing real world performance on an OS that most use, and to Intel for tuning their drives for it. I'm happy the other manufacturers are losing business..maybe they will also tune their drives for real world performance and not synthetic benchmarks.
To the poster above: do you work for OCZ or Samsung?

tshen83 "A very thorough review by tshen83, an hour agoBUT, still based on Windows Vista.

As long as these drives are marketed toward said OS, why would you not use it? Most of us wouldn't recognize Solaris if we saw it! And I believe you seriously overestimate yourself if your gonna drill anything into Anands head! You might need your own site, huh?
Great Job Anand! Don't forget to remind these CEO's that they also need to provide any software needed to configure and optimize these drives to work properly. ie go to OCZ Forums and try to figure out how to align, optimize and keep your drive running like it's supposed to, in less than 4 hours of reading! It would be nice if these companies would do their own beta testing and not rely on early adopters to do it for them!

Anand it would be really helpful to have a list of SSD companies blacklisting you so I know which ones to avoid. In general it would be nice to know who doesn't provide review samples to reputable sites.
