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.

If you get Newegg's specials, one of the codes is for the 30GB for $103 with a $20MIR, so $83 with shipping if the rebate comes through. At the size I would want (~120) the Super Talent undercuts the OCZ slightly.Does anyone know if you can install the firmware of one maker to another maker's SSD? For example, assuming both the Ultradrive ME and the Vertex use the same Indilinx controller, and say Super Talent chose to release it with the firmware which optimizes for higher sequential speeds, would the user be able to choose the firmware which optimizes for less latency?

Ah, no editing?!A-Data's "300 plus" SSD also uses the Indilinx controller.

"The Anatomy of a SSD" should instead read: "The Anatomy of an SSD"Flunk - Wednesday, March 18, 2009 - link
Yes, because S is a vowel...abudd - Wednesday, March 18, 2009 - link
Assuming SSD = "es-es-dee" then "an SSD" is right. If it *sounds* like a vowel, use "an".JarredWalton - Wednesday, March 18, 2009 - link
Yes, *but* SSD could also be read as "Solid State Drive" instead of "ess ess dee", in which case you would say "a SSD". I tend to read it as "ess ess dee", but Anand thinks of those letters as "Solid State Drive".Potato, potato, tomato, tomato... let's call the whole thing off!

When reading acronyms you're supposed to think of them as the letters, i.e. when you see RAM, you think "ram" straight off not Random Access Memory. When you see "IBM" you think "eye bee emm" not International Business Machines etc etc. It would take ages to read an article if you had to stop and think out all the full wording of acronyms as you're reading them.I'm going with the correction of "Anatomy of an SSD". Correct English fullstop.

By your comment, you suggest two different things, and that's really okay. That was my point: when you see "RAM" you probably thing "ram" as in the animal... not "Are A Em". You say "a RAM stick" not "an RAM stick". I'd guess most people think of SATA as "Ess A Tee A", but if you talk to most computer techs that are in the know, it's "say-te" so you would say "a SATA drive".And you know, I'm sure plenty of people will agree with the correct way of saying SATA, and that's perfectly okay. English really is a very flexible thing - particularly in the tech world - and rarely is there an "always right" way of saying things. If Anand wants to say "a SSD" and others want to say "an SSD", I'm not going to try to declare one group or the other correct. They both are, depending on your viewpoint.
