Anyone know where I can find the very fast Samsung SSD. On there website it just shows computers that have it; I'm looking to just buy it separately.
Got a tip for us?

Where can you buy a Samsung SSD?

I assume you mean the 256 gb one ?
you can find that on ebay i think around $789 though
I think the 128 gb version is actually slower
because
http://cgi.ebay.com/SAMSUNG-256-GB-...5|66:2|65:12|39:1|240:1308|301:1|293:1|294:50
this is the fast hdd the 256 gb one which is constantly listed as
" 220 Read / 200 Write"
while the 128 gb

"100MB/s read; 80MB/s write "
I wanted to use the 256 gb one as a boot/scratch drive in my new mac pro (one i just ordered) but price is too high
Yes. I have been doing some research on trying to find the fastest ssd that will work with boot camp and also looking at what will be out in mid july- September (when I plan on buying a ssd).
The intel ssd has super fast read times but super slow write times compared to the read times. Many traditional hdd's have faster write times. The fix to this seems to be raid 0.
I want to get a SSD when Snow Leopard comes out, so Im looking for some of the fastest now. Do you think Intel or any other SSD maker will announce a price drop or new models? And BTW, I can't do raid, since I'm using a laptop. What SSD would you get if you had a laptop?
A few questions:
1. Do you have the OCZ Vertex? If so how do you like it?
2. I heard somewhere that it was a rebranded Samsung, or is that a different drive?
3. What's the difference between "MLC" and "SLC"?
4. It looks to me that the 128GB version is the same as the 250GB version--same read and right speeds, just a differenct size. Is that correct?
5. What is "Cache"? Is it good to have more or less?
6. How much hours is 1.5E+06?
Thanks a lot
newegg has it...$669
still too rich for my blood.

I have the Vertex and I love it. No problems.
It is not a rebranded Samsung.
SLC is "better" but much more expensive. Someone who's smarter than me can explain it more.
The speeds I have listed for Vertex might be slightly off due to the numerous firmware updates recently.
It's good to have more cache, but with SSDs being as fast as they are, I'm not sure if it matters much.
1.5E+06 is scientific notation for 1,500,000 (1.5 million), basically the claimed lifetime of the drive is 1.5 million operating hours.
SLC = Single Level Cell; chip can only hold 2 power states, ON or OFF.
Possible states: 0 OR 1
MLC = Multi Level Cell; chip can hold multiple power states, currently it's commonly 4, Level 1 can be ON or OFF while Level 2 can be ON or OFF. Possible states: 00 OR 10 OR 01 OR 11
Since to write to a cell you need to set the whole thing, so for SLC, you only need one or off, for MLC there are multiple steps. So since there are more steps, it takes longer. But the advantage is cheaper to make since you only need so many less MLC chips to have the capacity of muliple SLC chips; however the drawback is that MLC will be used more, since if you have a cell thats 00 and you want 11, you need to do 10 then 11. (That's just layman terms, not scientific) That wears the cell a lot faster.
They say 1.5MTBF, but in reality, it's 10,000 (erase and write) cycles for MLC and 100,000 (erase and write) cycles for SLC, so you're paying for 10x the life at about 3x the price. Really it shouldn't matter, since drives will be so much cheaper (with larger capacity and faster speeds) in a few years, you'll want to upgrade anyways.
When deciding on a drive, there are other factor at play, such as controller, cache, write-leveling algorithms, etc.

There is a fair amount of misinformation in this thread. SLC in theory is better but as I understand it, the Samsung MLC is actually much faster than the older SLC so in this case the Samsung MLC is superior to the SLC.
Another issue is that not all speeds are equal. Typically the manufacturers cite maximum sequential read/write speeds, but random read/write speeds are actually much more important and much less reported.
If you want to do your research, and learn more about this, read anandtech.com ssd anthology. The collumnist has actually affected how some manufacturers produce their ssd. It is a long but helpful read.
From what I gather, Intel x-25 is the top performer but lower capacity; samsung mlc 256 if you want best combination of size and speed; new OCZ vertex if you want a top performing ssd at a lower price (but size is still limited).
Personally im going to wait a few months for prices to come down and then im picking up the Samsung 256 mlc.
Hope all of this helps.

"FTD56GE25H ST56A6E25H 256GB MasterDrive RX
2.5" SATA-II (SLC) 230/200 MB/sec"
anybody know how much that will be? and when it will be available?

1. How long have you had the Vertex for?
2. Which model did you get?
3. I read that the write speeds of SSD drop after a period of time. What is the read and write speed of it now?
After checking samsung's website it appears they are both rated for 220 read and 200 write.

With MLC SSDs, it's easier (and therefore cheaper) to build larger capacity SSDs. A 256 GB SLC SSDs costs in the thousands of dollars.
