I'm not too worried about capacity, most models have more than one anyway. But what is the fastest? I used to think its the x25E but now ive read about crucial and ocz?? I need whatever is the fastest for a research project.
 
A typical SSD (regardless of brand) will only ever be as fast as the data bus on your system board. Intel SSD's are the fastest going at the moment from my understanding.
 
The fastest SSD today should be the Crucial RealSSD C300 but it also required your motherboard supports the new SATA 3 to take full speed. If SATA 2 then any of the Sandforce SF-1200 SSDs like Corsair Force, Vertex 2, A-DATA S596, but OCZ have announced that they will make a Vertex 2 Pro which uses the faster SF-1500 Sandforce. However OWC Mercury Extreme and OCZ Vertex Limited Edition both uses a Sandforce controller thats somewhere in between the performance of an SF-1200 and a SF-1500 Sandforce.

Crucial RealSSD C300 - 355MB/215MB sec Read/Write | Average Access Time < .1 ms
OWC Mercury Extreme - Over 260MB sec Read/Write
Corsair Force - 285MB/275MB/sec Read/Write

Are you talking about controllers? So if i have SATA 2, Vertex 2 or Pro when its out? SATA 3 = RealSSD C300?

Im hoping to use these because im writing a real-time system where im running out of memory for storing files and may have to read directly from the file, say every second or 2 or 3. EDIT
Probably reading several hundred MB every 1-5 seconds.

Yeah I'm talking about the Controller in the SSD as this is the most important part :)
OCZ just announced like 2 days ago on their forum that they will make the previously canceled Vertex 2 Pro with the SF-1500 controller, however no specific date yet, only that the OCZ guys said soon so it can be anything from around 1 to 3 months i guess, dunno exactly. The Vertex 2 Pro i believe will still be on the standard SATA 3Gb/s interface.
And you might want to know the RealSSD has a bug with TRIM thats being fixed for mid April so it will require a firmware update if you get such a drive now but i guess its easy to update with their tools.

For the 2 Micron RealSSD models:
RealSSD C300 (up to 355 MB/s read and 215 MB/s write) using SATA 6Gb/s
RealSSD C200 "slower cheaper model" (up to 170 MB/s read and 70 MB/s write) using SATA 3Gb/s


Unless you have a new Motherboard, you probably have the standard SATA 3Gb/s support like many do on the board so you cant max the RealSSD C300 on it. It will run according to Micron site at 265MB/s Read and 140MB/s Write for 128GB model. The 256GB RealSSD C300 model used with a SATA 3Gb/s interface on the motherboard runs at 265MB/s Read and 215MB/s Write.

Take a look at these comparisons for more info :)
A-DATA S599 100GB SandForce SF-1200 Solid State Disk
Corsair Force Series F100 100GB SSD Featuring the SandForce 1200

If you want THE FASTEST then you want a PCIE SSD

Price is something special (about 3500 for 1TB) but check out the OCZ-Z Drive

Some numbers are: 870MB/s max read 780MB/s max write, freaky stuff.
 
You're probably more cost effect to get 3-4 SATA drives and RAIDing them together unless PCI-E drive costs have come down a lot.
 
I didn't mention PCI-E SSD since the costs :eek: and raiding SSDs will mean you loose TRIM support so performance will degrade slowly over time until supported drivers are released which can be many months away or more. You loose TRIM with both choices but raiding SSDs will be cheaper then these Z-Drives probably, so i agree with Jokester if you want to go this way when we think of the costs.

Also a bunch of PCI-E SSD are build on 1-2 gen older tech now that the next generation SSDs controllers are out from Micron, Sandforce, Indilinx ECO, + others. So be sure if you looking at PCI-E SSD thats its not a 2 gen old model. Intel will be out with their next SSD gen at around christmas, but might release a higher capacity SSD in the meantime.

Haven't Intel released drivers with TRIM support within RAID environment? I thought I read that somewhere recently.
 
Thats a common mistake due to some of the first websites reported this in error.
What the currently Intel driver does is that it allows for running an SSD with TRIM alongside a raided HD setup but the SSD must be outside the array itself.
