slimeballzz Posted May 7, 2009 Share Posted May 7, 2009 I just noticed NCIX selling this SSD and I found nothing about it on the web. I'm assuming this was just released recently and silently... My questions are: 1. How does it compare to the S128GB and P256GB models? 2. What does the "M" stand for on the label (labeled M64 on the drive)? 3. What controller is it using (Samsung, Jmicron, Indilinx)? 4. Is there trim support for this drive? 5. Will it be firmware upgradeable to support trim if it doesn't already have it?

MrSomebody Posted May 7, 2009 Share Posted May 7, 2009 I bet money that it is using a Samsung controller since all of Corsair's other ssd do. However, it's read/writes speeds are much better then the 128 ssd... and it's a very good price (compared to the competitors). Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 7, 2009 Corsair Employees Share Posted May 7, 2009 The 64 Gig Drives are not controller specific drives so we have not specified a controller that we use or will use as it will be subject to change at any time with out notice. And the current Spec of our 64 Gig SSD 9CMFSSD-64N1) is 170 MBps Read and 100 MBps Write. But the current drives are using the JMicron JM602 controller.

MrSomebody Posted May 7, 2009 Share Posted May 7, 2009 But the current drives are using the JMicron JM602 controller. :( that just ruined my day. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 7, 2009 Corsair Employees Share Posted May 7, 2009 Sorry about that but also this is the "B" version that is much more stable and the spe'c has been corrected. Link to comment Share on other sites More sharing options...
MrSomebody Posted May 7, 2009 Share Posted May 7, 2009 Curious, do these have on-board cache? I was under the impression that most JMicron controllers don't have a cache, which causes system freezes/stutters. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 7, 2009 Corsair Employees Share Posted May 7, 2009 Curious, do these have on-board cache? A: NO there is no Cache on this SSD, sorry! I was under the impression that most JMicron controllers don't have a cache, which causes system freezes/stutters. A: As I stated previously that was for the "A" version and we are using the "B" version which has not displayed those symptoms. but also this is the "B" version that is much more stable Link to comment Share on other sites More sharing options...
MrSomebody Posted May 8, 2009 Share Posted May 8, 2009 Thanks for answering. I'll stick with the 128gb version :D: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 8, 2009 Corsair Employees Share Posted May 8, 2009 NP and I just set the 64 Gig version up on a A8N32-SLI just to test and it was quite fast and stable so I dont think you will have any problems either way.

jccds Posted July 21, 2009 Share Posted July 21, 2009 How can i see that a M64 is Rev. B or even a newer one? Thanks in advance. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 21, 2009 Corsair Employees Share Posted July 21, 2009 jccds I am sorry but I do not understand your question, but this specific drive in question is no longer in production. You would have to go with CMFSSD-64GBG2D (Samsung) or CMFSSD-64D1 (Indolinks) drives unless a reseller had old stock of the CMFSSD-64N1 (J-Micron) drives.

leexgx Posted July 21, 2009 Share Posted July 21, 2009 the m64 is not an drive any one should get (unless its the CMFSSD-64GBG2D (Samsung) or CMFSSD-64D1 drives) due to the problems with the JMicron JM602 controller (a or b the problem is still there, untill the new JMicron controller comes out in the next months or towards the end of the year should be avoided until then), if you are got an M64 buy two of them and put them in raid 0 and turn on Write back cache in the intel matrix software so Writes are performed when reads are not happening get the S/P128 corsair SSD or the P256 as thay do not suffer from them problems due to the drives having cache and you do not need to raid the above drives Link to comment Share on other sites More sharing options...
JohntechUSA Posted July 21, 2009 Share Posted July 21, 2009 leexgx What are you talking about the CMSSD-64N1 drive using Samsung Flash and the second generation Jmicron controller has no problems; I am using one now and it runs great in fact I am looking for another one that I can use with a Raid setup. But I would agree the newer Samsung Drives would be better choice if you have not purchased the drives yet. But only because of the faster performance not because there are any problems. I have not seen any issues as of yet and I have reloaded the O.S. on seven different MB's to date and it has and is running great. You can see the stats on this post about Partition alignment, which correct me if I am wrong but you and several others made a big stink about and that was proven not to be the case.

leexgx Posted July 22, 2009 Share Posted July 22, 2009 Google < The SSD Anthology > and goto page 17 (as there was No point in posting the link as it would of been moded out any way) the new m64 corsair SSDs i believe do not use JMicron any more they use samsung or some other make (we are talking about the controller chip here not the flash and the longevity of the drive) Some motherboards or IDE/AICH drivers setups can have lag it very much so happens when all Blocks on the SSD now need to be erased before an Write can be performed, RAID 0 on intel ICH seems to Hide the issue once the Option Writeback cache is turned on, this is an Luck issue with JMicon drives but if you looked at that page above you can see why it can happen your better getting the Corsair s/p128 (the S128 i have now may be slow on data rate but every thing works fast showing data rate is Not that important, its more Write access times that no SSD maker shows, JMicron controller IOPS is slower then an HDD on Write access once the SSD needs to erase before Write) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 22, 2009 Corsair Employees Share Posted July 22, 2009 That article was mostly about one of our competitors and they never mentioned our drives. I have not seen any of these issues as explained here in this article but I would agree go for the next generation drives as they are faster.. Not to mention the Corsair M-64 Drive is no longer available.. From that article and about the controller we used. For starters, a second revision of the JMF602 controller came out last year - the JMF602B. This controller had twice the cache of the original JMF602A and thus didn’t pause/stutter as often.

leexgx Posted July 22, 2009 Share Posted July 22, 2009 http://rd1ugg.bay.livefilestore.com/y1pZzXjBbsQPzcGPDJiZ6mu5qlXGXhrdP8O5X0X22Lca0qxe6IR2WLylni4w5Ay8M5DQhaRi8WAVcavnHPGR9VaEACDjzdgs3O0/1JMicronSSD.png above is what happens once the SSD has to erase before write, as from my tests on my Own corsair S128 the access times and Write MB/s are nothing like the above, as long as the current SSD that are been sold are not using JMicron all is ok, when they come out with new version the topic is old i think for the most part due to you cant buy the older m64 now Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 22, 2009 Corsair Employees Share Posted July 22, 2009 Yes its really a mute point and as I said I agree with you for the most part go with the new Generation Sansung Drives or the next generation Indilinx Barefoot controller!

leexgx Posted July 22, 2009 Share Posted July 22, 2009 from my SSD i go with the samsung based ones even thought mine is slow on the data rate side, it operate Far faster then my hdd, as Intel have come out with something new corsair may lower there prices soon so 50/50 if i get the new P128 (but personally i not sure if i see the improvement maybe in COD4 when its loading the maps but its loading them faster then what my HDD was any way) the Indilinx ones seem to require the wiper tool running every week or so as thay seem to degrade alot faster (why does Corsair recommend putting SSDs into RAID 0 as there is currently No way to run the wiper tool or use windows 7 TRIM command does not work on RAID only on SATA/AHCI mode when they degrade they be slower then one SSD in its own) only thing that lets them down (S/P) is no Wiper Trim tool, But my corsair SSD has Yet to degrade still operating at its spec speeds, so debatable if it needs one but when it does degrade having to use HDDerase is an pain (have to clone the SSD) you really need to put in your FAQ not to do full formats if they want to do an full format to erase every thing they should use the HDDerase tool and then use an Quick format only (as an full format will slow the SSD down) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 22, 2009 Corsair Employees Share Posted July 22, 2009 the Indilinx ones seem to require the wiper tool running every week or so as thay seem to degrade alot faster (why does Corsair recommend putting SSDs into RAID 0 as there is currently No way to run the wiper tool or use windows 7 TRIM command does not work on RAID only on SATA/AHCI mode when they degrade they be slower then one SSD in its own) A: Where have we suggested using a Raid? I don't know that I have ever made that suggestion, only if someone had asked about running them in a Raid configuration, and that is not a suggestion! only thing that lets them down (S/P) is no Wiper Trim tool, But my corsair SSD has Yet to degrade still operating at its spec speeds, so debatable if it needs one but when it does degrade having to use HDDerase is an pain (have to clone the SSD) A: There is no utility needed for the drive you have and why none has been published or posted. you really need to put in your FAQ not to do full formats if they want to do an full format to erase every thing they should use the HDDerase tool and then use an Quick format only (as an full format will slow the SSD down) A: Thanks for the suggestion we will review the F.A.Q this week and see about adding that.

leexgx Posted July 22, 2009 Share Posted July 22, 2009 A: Where have we suggested using a Raid the product main page that relates to the X64/128/256 http://www.corsair.com/products/ssd_extreme/default.aspx and the second and 3rd response from you are related to each other, you have to do an low level format to reset the SSD to an new state (if it has degraded but thats more samsung fault not corsairs for not providing an tool or corsair not nagging for one), where if there was an Wiper Trim tool for samsung based SSD that would not be needed to use HDD erase as thats complicated and time consuming for the end user not me but your avg joe it would be Link to comment Share on other sites More sharing options...
Wired Posted July 22, 2009 Share Posted July 22, 2009 IMHO, they didn't suggest it, only referenced it. Link to comment Share on other sites More sharing options...
leexgx Posted July 22, 2009 Share Posted July 22, 2009 should not be reference to it really if it was samsung that was been set in raid 0 it takes months (i tell you when mine does, could take some time) for them to degrade, but Indilinx ones can degrade in an week or so on there currant 1.3 firmware (that all makes that should be using) why the wiper tool is needed more for them type of drives SSDs do not need RAID due to the IOPS and TRIM does not work on RAID so it end up slower then 1 SSD Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 27, 2009 Corsair Employees Share Posted July 27, 2009 The Indolinx drives will come with Utilities but it is not needed for the Samsung Drive, not to mention Samsung has not provided one. Link to comment Share on other sites More sharing options...
leexgx Posted July 28, 2009 Share Posted July 28, 2009 The Tools do not work in RAID (not at the moment but not likely to support it yet or at all up to RAID driver makers, No point in RAID for SSDs any way not with the second gen ones), why Indilinx Product page should not have that info on there relating to use me in raid (but no warning about they be slower then 1 SSD in an week or so), really i think your samsung based SSDs are the best option (as long as you do not do an full format or run out of free space they are fine), just need to ask them for an Trim tool and Firmware updates as your lagging behind the Prime make of Indilinx based SSDs (there is 2-3 dif firmwares for the corsair P based SSDs) Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted July 28, 2009 Corsair Employees Share Posted July 28, 2009 There is no data to support that in a RAID configuration there will be an issue. But I have set these up for lab testing to see if we can duplicate any of these issues but to date we have not. So I am not sure what to tell you other than the information you have stated might be from another source not using our drives. Link to comment Share on other sites More sharing options...
