The OCZ Summit: First with Samsung’s New Controller
Well before Intel ever introduced the X25-M, there was one chip company who had already been making well behaved SSD controllers: Samsung.
The fit just made sense; Samsung makes NAND flash, Samsung makes microprocessors, thus Samsung should make SSDs.
Samsung is a unique company in that it is very well known in both the OEM and consumer spaces. You’ll find Samsung ICs in nearly everything; DRAM, smartphones, even the flash on the JMicron drives I’m always complaining about - Samsung makes it. With strong OEM ties as well as a good-sized HDD business, it didn’t take long for Samsung to get into the SSD market.
Because it was primarily selling SSDs to OEMs like Apple and Dell, the controller had to be perfect. Stuttering, pausing and strange reliability problems wouldn’t cut it. Apple wouldn’t dare ship a MacBook Air with a SSD that would deliver anything less than a flawless usage experience.
With that sort of pressure, Samsung’s SSDs and its controllers always just worked. Even before the JMF602A ever shipped, Samsung’s controllers were doing just fine. They had to. Their customers were Apple and Lenovo, there’s no room for silliness.
There were two problems with Samsung’s controllers: 1) they were expensive, and 2) they weren’t very fast.
The cost drove SSD makers to companies like JMicron, to drive SSD prices down faster than Samsung would allow. The performance made it so that the very first SSDs weren’t much faster than the fastest hard drives, and in some cases they were slower.
Late last year Samsung announced a new version of its MLC controller that would slowly replace all of the existing Samsung MLC drives in the market. OCZ was the first to get us a sample based on this new controller, even faster than Samsung and the drive is called the Summit.
OCZ's Summit, it's an early sample
Lots of glue and no screws on the pre-release Summit. The final drive should be ready soon.
I’ll save a detailed investigation into the Summit and Samsung’s controller for another article, this one is already long enough. The Summit should be priced similarly to the Intel drive, although OCZ is trying to make it cheaper. The performance level is designed to be greater than the Vertex and competitive with the Intel X25-M. We’ll see about that shortly.

I love it when people critique someone's critique of grammar... and get it wrong.It's an SSD, not a SSD.

I would like to know the firmware version of Vertex used in your review. To me sounds the old 0112kensiko - Wednesday, March 18, 2009 - link
Yes that is important to know.I'm sure this is not done with the latest firmware available which is 1199. This version got better performance.
Firmware 1275 is coming also.
Anand, will you update your benchmarks with the latest firmware?
If not, then the benchmarks are obsolete.
Anand Lal Shimpi - Wednesday, March 18, 2009 - link
I tested with the shipping firmware for this article (0122). I've been playing around with 1199 in the lab and will most likely have an update in a couple of weeks once I've done a thorough evaluation of it. By then I should also have the final version of the new Samsung drive and maybe even some other interesting things.For now, I've got to get to work on the new Mac Pro and the updated Ion article :) I need a small break from SSDs por favor :)
Take care,
Anand

Awww, don't you have some underlings to do your SSD-related will?Would love to see an update, and would love to see Corsair's SSD drive tested as well (it's based on Samsung's last generation MLC controller, and doesn't seem to emphasize sequential like the Summit does).
Anand Lal Shimpi - Wednesday, March 18, 2009 - link
I will do an update on the new firmware, I just want to do it right so it'll take some time :)I'll put in a request for the Corsair drive as well :)

Page 29: "Not all applications will launch faster than a VelociRaptor on a SSD, but let's not forget that the VelociRaptor is the world's fastest hard drive."Really? What about the nice and speedy enterprise-level 15k SAS/SCSI drives everyone neglects to acknowledge? :)

I believe it refers to consumer drives. While SAS drives are beginning to be a possibility on the desktop with newer motherboards supporting them natively, the drives themselves are too expensive and too noisy for most consumers to actually want them.FishTankX - Wednesday, March 18, 2009 - link
Good info. However, I noticed one mistake.Second page
Samsung had a MLC controller at the time but it was too expensive than what SuperTalent was shooting for.
