  1. Can anyone tell me if you get full 10gbs speed when using both ports of a card between the two other connected devices using the same cards and 5m appropriate cables?
  2. Anyone tried this product?

    I've used quite a few IcyDock products but not either of those. Their hot swap front case caddy is handy if you swap drives around a lot
  3. There are no video links on YouTube for what you need, assuming you must have the data you *must* use a recovery service that will open the drive in a clean room and attempt to copy the data to another drive. It is not guaranteed to work and if it does it is very expensive. Now read all of the responses again, and you will see a theme -- you cannot do anything about this yourself and to use a proper service will be very expensive. In the future you will never again forget the importance of good backup practices.
  4. 512e or 4Kn Format

    Update. Things went very well with the new array. I used 5 8TB He8 512e drives and an Adaptec 8805 controller. I stuck it into my NAS box on the second x8 PCIe connector (the first has my old 6805 with 8 3TB in RAID 6), installed the Win 7 x64 driver and after the build was good to go. Took around 30 hours to build the RAID 5 and 14TB of data transfered from the old array to the new at 500-600MB/s.
  5. 512e or 4Kn Format

    I selected the He8 for their reliability and needed a large space with as small a number of drives as possible, plus I got the 8TB drives for only $441 each. Enterprise quality (10E15, 2.5M hours MTBF) 8TB drives are not terribly common AFAIK and I have had excellent results with HGST enterprise drives since they first came out. I don't feel comforatable with the Seagate SMR 8TB drives yet, so they were not considered at all, and most of the Seagate offerings are only 10E14 drives with MTBF around 1M hours. The energy savings of the He8 will just be a bonus since they will run 24/7. So far I am very happy with the drives, and the Adaptec 8805 that I went with instead of the 71605 since i got it for over $250 less and really didn't need 16 ports. I'll give an update report in 3 or 4 months after the data migration is complete and the new array has had some service time.
  6. I'm looking at the HGST He8 drives for a RAID 6 array. Is there any particular advantage to using the 512e format or 4Kn format as both are supported by the Adaptec card that I am using? The 512e seem a bit cheaper in the 8TB capacity. Thanks!
  7. Samsung 2TB SSD: when?

    Why settle for only 2TB if you have the budget?
  8. RAID 6 writes have really slowed

    I got lucky -- second disk I pulled was the problem. Stuck in a replacement and rebuild is done. Not sure why maxView didn't detect it, but the card is out of warranty so no more support. Thanks
  9. I have an Adaptec 6805 with 7 3TB Hitachi 7200rpm disks in RAID 6 (Win 7x64, i3-2100, 8GB RAM, just a storage box no other tasks). 6-8 TB empty space still and updated to the latest firmware and storage manager software. Reads are as good as ever, but over the past few weeks writes have slowed to a crawl, like 20MB/s. All disks and the array indicate optimal status from the boot screen and storage manager software. It sure seems to me like a disk is bad, just hard to figure out since they all are listed as optimal. Any ideas on troubleshooting this? Thanks!
  10. Big sale on some LSI RAID cards at Newegg today -- I figured that it was an error but checked and it is 50% off the already discounted price for some models today 12/2.
  11. I have two of the 32GB models and they are great for those of us who are tough on things, mine have been through the laundry many times with no ill effect or data loss. Not intentionally, but the GF does not check pockets on laundry day.
  12. SSDs much slower than online reviews

    Agreed, in my experiences with Marvell controllers on X58 boards, you are better off using the Intel SATA II in AHCI mode. I would probably also secure erase the Mushkin if it "got filled up." I've done that a number of times with similar drives and it brought them back to expected performance levels.
  13. My final report on this effort. Unbelievably, the modify finished successfully yesterday (Sept 23), so 16 days to migrate a 6 disk raid 5 to a 7 disk raid 6 with 8TB of existing data, with a failed drive during the process that hung things up for a few days. Obviously this was just done to see if it would work, I would highly recommend just building a new array and reloading the data. But it was fun to see that the array was optimal yesterday.
  14. Well I finally got the raid level modification to work using the command line, there were two things that were a bit tricky. (1) dedicated hot spares that will go into the array have to be unassigned first, and (2) the channel# ID# listed for all the drives is not the channel 0 or 1 that shows up under MaxView in the graphic view -- rather the data listed for each drive if you look at the properties under the physical view was correct. And ARCCONF only required the addition of one disk to migrate from RAID 5 to 6. So with 7 disks attached (none on channel 1 connector 0, which would have been 0 4) the syntax that worked was: ARCCONF MODIFY 1 FROM 0 TO MAX 6 0 0 0 1 0 2 0 3 0 5 0 6 0 7
  15. Data Loss 3TB Internal Hard Drive

    It sounds like you initialized the drive using MBR rather than GPT in the first place, which won't work correctly on a drive of that size. If that is the case, I would get all the data off, and start over. But first you should check to see that your motherboard/bios supports drives over 2.2TB -- some of the older S20 machines may not have, at least not without a bios update.
