July 27, 201015 yr Author What program did you use to bring up that health screen? CrystalDiskInfo (windoze only... sorry) It is what Ocz recommends.

July 27, 201015 yr Are you running SMART tests on an SSD? You should NEVER do that! smart tests are not supported on the SSD's. It even says it when you do a smartctl -a. I did update to a later version of smartmontools and it seems to handle things differently. I'll see how this goes over the next few weeks.
August 2, 201015 yr Author Ocz had to pull back stock for a driver issue, but they are not on the way to resellers. I also got confirmation from Ocz, that OCUK has stock, and the stock is the upgraded versions. http://www.overclockers.co.uk/showproduct.php?prodid=HD-052-OC

August 3, 201015 yr Boy I would sure like one, but I think I'm gonna wait a while. I think a real ACARD ramdisk is what I need for my vmware environments. I see so many sectors a day getting taken off line on my SSD. I would rather write to the ramdisk all day, then rsync to the SSD once a day for backup. This unit is so cool, When you get it post a review for us!
August 7, 201015 yr Author FWIW, I put the Revodrive in unRAID, and it does not see the raid as a set, but two individual drives. I've seen the same behavior with other hardware raid (i.e. on the mobo) in unRIAD.
August 7, 201015 yr Hrmph. What's the speed performance of the split drives (without the benefits of HW raid)? Or can it not be utilized without it showing as a single drive? I wonder when OCZ will release updated firmware for that issue. I imagine the Mac OS would see them the same way. I'm sure they want to bring the benefits of their HW Raid array to everyone regardless of OS.
August 7, 201015 yr Oh, I thought maybe it was a firmware thing since they say the drive/array is bootable and didn't seem to indicate any driver was needed for WinOS, so I assumed other OS's wouldn't need a driver either. Or maybe I misread something that was in a preview/review. Woops, seems I misread this bit from Anandtech's preview -- "OCZ provided me with a set of 64-bit drivers for the Sil3124 controller and I was on my way. Windows 7 x64 installed without a hitch."
August 7, 201015 yr Actually I'm not surprised the two drives are not seen as one. In my SIL3124 with RAID Bios, the drives are seen individually as is with my JMB Micron. There might be some driver required in linux. What is the speed of the "single" drive?
August 7, 201015 yr Author What is the speed of the "single" drive? Same as the Vertex2 Sequential Read : 200 MB/s Sequential Write : 125 MB/s Symbol: SATA_SIL24 Linux driver only supports it in SATA mode, not RAID.
August 7, 201015 yr Dam... Maybe you should post it on newegg for others just in case. What does OCZ say in the forums?
August 19, 201015 yr Author I think a real ACARD ramdisk is what I need for my vmware environments. I see so many sectors a day getting taken off line on my SSD. The ACARD is not much faster than a fast spinning disk. Have you considered adding more physical RAM to your machine, using VSuite Ramdisk to create a nonvolitile ramdisk, and having your images there? With VSuite, your ramdisks can automatically be saved to a spinning disk at shutdown, and restored at boot.

Have you considered adding more physical RAM to your machine, using VSuite Ramdisk to create a nonvolitile ramdisk, and having your images there? With VSuite, your ramdisks can automatically be saved to a spinning disk at shutdown, and restored at boot. I'm running linux. XP under vmware under Linux. I have 12GB. I'm getting from 33 to 150MB/s on the OCZ Vertex Turbo right now. I may bump the machine up to 16GB, but I don't think it's needed. When I do a sync, there are massive writes to the SSD and it takes a moment or so to flush out. So memory wise I think it's good. I think the advanced Acard in RAID0 mode (which rates at almost 500MB/s) would be fine. I leave the XP and W2K environment up all the time, so they are constantly updating their own disks. I think a worry free ram sata drive with periodic backups to the 10KRPM drives should be good.
August 19, 201015 yr Author I see. Too bad there is not a native Linux version of VSuite .... here is the benchmark I ran: Sequential Read : 3701.884 MB/s Sequential Write : 2917.564 MB/s Random Read 512KB : 3582.635 MB/s Random Write 512KB : 2855.466 MB/s Random Read 4KB : 749.280 MB/s Random Write 4KB : 625.422 MB/s That is not just fast... that's insane fast. I wonder if there is another vendor with a nonvolitile ramdisk like VSuite for Linux.
August 19, 201015 yr I see. Too bad there is not a native Linux version of VSuite .... here is the benchmark I ran: That is not just fast... that's insane fast. I believe tmpfs would provide similar results. I wonder if there is another vendor with a nonvolitile ramdisk like VSuite for Linux. from what I read vsuite is not really non-volitile. It's a memory based ramdisk that has automated backup/restore. Actually the issue is I have a 9GB XP image that is up and running 24x7. I'm sure this is putting wear and tear on the SSD. I see resets every now and then in the syslog. The issue with using tmpfs is I would need 9GB for the XP image. Then routines to backup and restore. That's easy enough, but I have 12GB of ram now and I run other VM's. I really don't see myself expanding to 32GB just to run XP in a faster way. If I bumped the ram to 16GB and used the ACARD for 16GB swap, I could throw XP vmware onto a tmpfs for lightning fast performance. Yet in that respect, I could just use the ACARD with 2 SATA ports in RAID0 and have it battery backed with a CF card for backup/restore. This lets the 16GB ram drive survive reboots and maintenance as long as it's within a few hours. The acard product is pretty nice (albeit expensive). Not sure it's worth it yet. I'm waiting on RH6 to decide. At that point there will be better drivers in the kernel which support the SSD better. I tried upgrading the kernel and it failed miserably. I have to make another go at it to see if I can get it to work. I don't necessarily need such lightning 3000MB/s speed for vmware. It's a browsing station. Allot of it is in ram already. What I'm looking for is very fast access times with minimal write impact on the SSD. Going from 70Mbs to over 120MB/s with subsecond access time was the biggest improvement I'll probably see. Access is practically instantaneous when I click on something even in the virtual vmware environment. I'm mostly concerned with write wear. I'll probably have to wait a bit, It seems the ANS-9010 is out of stock in allot of places.

Windows and NTFS is hard on SSDs... you should turn off a number of default settings in Windows when running an SSD. Check the Ocz forums.

Actually, with 12GB in the machine, I don't think it writes as much as it could. I believe the OS is caching allot. It's still tough on the SSD because I have it on 24x7.
