The SSD Anthology: Understanding SSDs and New Drives from OCZ

Game Loading Performance
I chose two games to show both ends of the load time spectrum. The first test is World of Warcraft, I'm simply timing how long it takes from the character selection screen to a fully loaded scene in the realm I've chosen. Fully loaded means no more popping textures or waiting for anything else to load:
The Intel X25-M does the best here, even slightly outperforming the X25-E thanks to a more consumer-optimized firmware. The two OCZ drives occupy the third and fourth places, followed by the rest of the pack. No hard drive can keep up here thanks to the superior random read speed of a SSD.
The Far Cry 2 test is simply running the default benchmark and timing how long it takes to get from clicking launch to the loaded level:
While the SSDs take the cake here, the VelociRaptor isn't far behind. Once again the two Intel drives take the lead, followed by the two OCZ drives. The Vertex and the Summit tie in performance.

Very nice and thorough article. I only lack more current status of TRIM command support in current operating systems. For example, Linux supports it since last year:http://kernelnewbies.org/Linux_2_6_28#head-a1a9591...">http://kernelnewbies.org/Linux_2_6_28#h...a9591f48...

Outstanding article that really helped me understand SSD drives. I wonder how much of an impact the new SATA III standard will have on SSD drives? I believe we are still at the beginning stage for SSD drives and your article shows that much more work needs to be done. My respect for OCZ and how they responded in a positive and productive way should be a model for the rest of the SSD makers. Thank you again for such a concise article.Respectfully,
Sinned

The first thing I thought of was Democracy. Don't know why. Maybe it was because a company listened to our common goal of performance. Thank you OCZ for listening, I'm sure it will pay off!!!araczynski - Saturday, March 21, 2009 - link
very nice read. the 4/512 issue seems a rather stupid design decision, or perhaps more likely a stupid problem to find this 4/512 solution as 'acceptable'.although a great marketing choice, built in automatic life expectancy reduction.
sounds like the manufacturers want the hard drives to become a disposable medium like styrofoam cups.
perhaps when they narrow the disparity down to 4/16, i might consider buying an ssd. that, or when they beat the 'old school' physical platters in price.
until then, get back to the drawing board and stop crapping out these half arsed 'should be good enough' solutions.

araczynski: The 4/512 isn't done by accident. It's done to lower prices. The flash technology used in SSDs are meant to replace platter HDDs in the future. There's no way of doing that without cost reductions like these. Even with that the SSDs still cost several times more per storage space.araczynski - Tuesday, March 24, 2009 - link
i understand that, but i don't remember original hard drives being released and being slower than the floppy drives they were replacing.this is part of the 'release beta' products mentality and make the consumer pay for further development.
the 5.25" floppy was better than the huge floppy in all respects when it was released. the 3.5" floppy was better than the 5.25" floppy when it was released. the usb flash drives were better than the 3.5" floppies when they were released.
i just hate the way this is being played out at the consumer's expense.

Anand,What a great article. I usually have to skip forwards when things bog down, but they never did with this long, but very informative article. Your focus on what matters to users is why I always check anandtech first thing every morning.

I'm curious what capacity is the OCZ Vertex drive reviewed. Is it an 120 / 250g drive or supposedly slower 30 / 60g one?Symbolics - Friday, March 20, 2009 - link
The method for generating "used" drives is flawed. For creating a true used drive, the spare blocks must be filled as well. Since this was not done, the results are biased towards the Intel drives with their generous amount of spare blocks that were *not* exhausted when producing the used state. An additional bias is introduced by the reduction of the IOmeter write test to 8 GB only. Perhaps there are enough spare blocks on the Intel drives so that these 8 GB can be written to "fresh" blocks without the need for (time-consuming) erase operations.Apart from these concerns, I enjoyed reading the article.

I also just created an account to post, very nice article!Lots of good well thought out information, I'm so tired of synthetic benchmarks glad someone goes through the trouble to bench these things right (and appears to have the education to really understand them). Whats with the grammar police though? geez...
