  1. Thanks, that's what I thought. I do have everything backed up, just being lazy.
  2. I have a RAID 5 array on an Adaptec 8805 (default stripe size used 256KB) that I just expanded by one additional 8TB He8 drive, all went well. But then I went into Windows disk management to expand the single volume of about 30TB by the additional 7.2TB. I get an error that it can't happen because it exceeds the cluster limit of Windows. I know that the default cluster size for Windows 7 for volumes of 16TB–32 TB is 8 KB and for 32TB–64 TB it doubles to 16 KB. I expect that is the issue that I have, crossing that threshold exceeds the cluster number limit. Is there any simple way to change the cluster size, perhaps with third party software rather than to delete the existing volume and create it again with a larger value and then have to copy all the data back from the backup volumes? Thanks.

    Seagate Releases 14TB Drives

    5 or 6 of the Ironwolf Pros may be my next main RAID 5 array and relegate my 8xHe8 8TB to backup. Just need to double check that my spare Adaptec 8805 will play nice, which I assume that it will.

    HTPC 4k ultra

    I would never suggest using a consumer motherboard RAID controller, any simple bios hiccup/update/bad karma and poof all gone. I've seen this way way too many times. At a minimum if you do it, have easy to access backup and lots of spare time. One of my older storage arrays has 8 3TB Hitachi 7200rpm drives, 7 in RAID 5 plus a hot spare that has performed flawlessly for years. They were relegated to secondary backup storage a little over a year ago just due to age and a new array of 8TB He8 Hitachi drives. Those too have performed without issues.
  5. While both are about the same, just make sure that a USB external drive is not your sole backup and when using them on Windows machines use the safe eject to help avoid losing your data in a mishap, I second the motion on HGST drives. I have 20 in two arrays that have been on 24/7 for the past 4 years without a failure. Yup, I know that I just jinxed myself.
  6. As continuum said, if the data is really important and you did not have it backed up to a reliable backup, you are going to spend significant money. USB drives are an extremely poor single source backup as they are easily corrupted in many situations. Moreover, one backup for important data is about as reliable as no backup. EaseUS should give you a refund if the product did not work for you and you first used the trial version and it stated that it would recover your data.
  7. Agreed, and just remember to safely eject the drive and have the computer on a UPS with automatic shutdown software if you leave the drive on a lot -- USB drives are easily corrupted if disconnected during a write.

    Quiet hard drive

    Figure out which drives you are interested in and then get the pfd product sheet off their web site. They all include acoustic specs. For example WD Black 6TB is 29dB at idle and 36dB when seeking. All major drive makers publish these, but there is little difference in modern models although the HGST He8 drives are more quiet at idle at 20dB. There are 10 of those spinning within 5 feet of me and I cannot hear them over PSU and case fans unless they are doing a significant seek, like loading a large database.
  9. HGST calls it ISE and it is their version of the standard Sanitize (T10/T13) SATA command. So you would have to check if drives support those -- I do not believe that many consumer level drives include that feature at this time. I primarily use HGST drives for other reasons -- like their quality, but that is an available attribute on most if not all enterprise models
  10. You have already created a RAID 1 array from the 2 disks. If you want to change it to something else you need to delete that array and create what you want. Basic is their use of separate disks and what they call JBOD is really akin to RAID 0 (so no fault tolerance). You don't have any disk groups, a Synology disk group comprises of one or more drives combined into a single partition, which would be like RAID0 or RAID5..
  11. My experience with the 2.5" Seagates is good, but never rely on a single drive for backup. Anything important should be on other devices, preferably in other locations. And always be careful to eject the drive before detaching to ensure that all writes are done, and use a UPS on your computer so it doesn't power off during writes to external drives. Just a few of the fun ways that USB drives can hose your data, whatever the drive size.
  12. While with most controllers that I have used I would just delete the array and then recreate it as JBOD then run DBAN, some Dell servers won't allow that but apparently will allow you to set each drive as a RAID0 and run DBAN like THIS guy describes.

    Controller for 4 8tb sas drives

    If you are sure that you will not expand beyond 4 disks *and* your HGST drives are 512e (not native 4k) you could consider an Adaptec 6405. I have a 6805 with 8 x 8TB He8 drives that works quite well as my backup storage to a newer 8805 setup. While Microsemi (now the Adaptec owner) has only done limited drive testing, HGST has a more extensive guide for their drives HERE. At one time I investigated using 4K native drives with the 6805 and found information that it would not work but have since lost the link. Newegg has the 6405 (which is 6Gb/s that I agree is more than adequate if you only use spinners) available for $269 after promo code HERE and then you will also need one Internal mini-SAS with power (SFF-8087 to SFF-8482) cable that is a 1 8087 to 4 SAS fanout cable and runs under $20 on Amazon and elsewhere.
  14. 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?

    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 https://www.amazon.com/DuoSwap-MB971SP-B-Drive-Caddy-Docking/dp/B007Q4EZEA
