    ZFS Performance Issues

    I will have to check that out for benchmarking. This array is not encrypted, the other box has 2 pools that are encrypted with GELI, but yeah I didn't encrypt this one because the processor lacks AES-NI.

    ZFS Performance Issues

    Oh snap, what are the odds my dd benchmark was just a bad choice? :D root@boxname:/zpool/zfs # /usr/bin/time -h dd if=/dev/zero of=sometestfile bs=1048576 count=10000 10000+0 records in 10000+0 records out 10485760000 bytes transferred in 14.765670 secs (710144553 bytes/sec) 14.77s real...

    For write: /usr/bin/time -h dd if=/dev/zero of=sometestfile bs=1024 count=1000000 For read: /usr/bin/time -h dd if=sometestfile of=/dev/null bs=1024

    ZFS Performance Issues

    Yes, I am using dd as root from the console. Actually, it's funny that you mention that, another thing that had happened is that during the testing I noticed the smartd was reporting one of the drives that was connected to the HBA was reporting bad/unreadable sectors. I have since removed that...

    ZFS Performance Issues

    So recently I have been working on building a second ZFS storage box, and so far it's performance is seriously underwhelming. This is certainly not my first rodeo, there is already a 65TB (usable) storage box encrypted with GELI on the network that performs faster. I am just at a loss for why...

    Media data raidz1 or raidz2?

    I understand your dilemma, deciding what to do with a 6 drive array is tough. I personally am not comfortable with less than double parity, but that is also bordering on overkill for a 6 drive array. If it were me? I would probably go raidz2.

    Where are the sales on M.2/PCIe SSD drives?

    I was so, so close to buying a 256GB XP941 from newegg yesterday for my new X99 build, it just seemed that it may be a bit too early to adopt it as my primary system drive. I ended up going with a Samsung EVO 840 - which seemed to be close enough to the XP941 in real world benchmarks. My board...

    Media data raidz1 or raidz2?

    I have been using double parity since I started doing massive media storage 5-6 yrs ago - I have also never had a drive fail. This either means that I wasted money on unnecessary redundancy, or that I will be saved when a drive eventually dies and all of the other drives in the array are in an...

    Areca ARC-1880i 6Gb/s RAID Card W/ BBU - Ends Feb 02, 2013 12:37:57 PST - $399.00

    Selling my trusty Areca ARC-1880i w/ the optional BBU for safely using write cache. Starts at $399, reasonable reserve (new you are looking at $750+ for the pair). http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=200885656659

    Switch to ZFS and losing space?

    All of the drives were encrypted in GELI w/ 4K sectors, which I believe is the default. I tried using 512 with the Hitachis because I believe they emulate 512, but the performance of the array ended up being worse. Compression wasn't enabled in windows, and isn't enabled with zfs. The data isn't...

    Switch to ZFS and losing space?

    Over the past week I have upgraded my storage server and transitioned from a hardware RAID 6 on an Areca arc-1880i to zfs on freebsd. I am using encryption as well, the hardware raid was encrypted in Truecrypt and the card was assigned to a Windows Server 2K8 R2 guest, now the drives are...

    Are my read/write speeds acceptable?

    How are they connected? 16/24 port Arc-1882? Chassis with built in SAS expander?

    Are my read/write speeds acceptable?

    Your writes are slow. Do you have a battery and caching enabled? My 8 drive RAID 6 on an Areca ARC-1880i does 750MB/s+ sequential.

    Slow External HDD

    Quite frankly that sounds about right from what I have seen of external USB 3.0 hard drives. Particularly if it is a "green" class drive in the enclosure. It will also be affected by how much is currently on the drive...

    HT Omega - eClaro, Claro II, and Impressions

    I've had a Claro Plus for a few years now, and I cannot speak highly enough of the sound quality of HT Omega cards.
