  1. I use 2 disks in drive pool. When use one single drive, the sequence reading or writing speed is about 160-240MB/s. When I change No Duplicate to 2x Duplicate, duplication start automatically. However, the duplicate speed will drop down from 100MB/s to 20MB/s, and the physical disk usage will increase from 60% to 100%, if click "Increase Priority" button. By the way, files being duplicated is big big files. This is awful. Hope it will be fixed. By the way, why read striping doesn't improve any performance when reading one big 2x-duplicated file? Reading speed can never be over 2
  2. There is a couple of issues and questions about measuring. Why it is not optimized / cached / smarter? Case 1: If there is a pool of 2 or more drives and one is disconnected for whatever reason - once the drive is back entire pool is measured. If that is large, cloud based pool with a lot of small files - a short interruption in connectivity triggers hours of measuring. Would that be possible to cache results of previous measure run and measure only the drive that was reconnected? Case 2: Four cloud based drives CLD1, CLD2, CLD3 and CLD4 are coupled in two
  3. Hi, referring to this post and how DrivePool acts with different size drives, I found myself copy/pasting a file and DrivePool used the same drive for the entire operation (as the source and the destination). This resulted in a really poor performance (see attachments; just ignore drive "E:", there are some rules that exclude it from the general operations). Same thing extracting some .rar files. Is there a way to make DP privilege performance over "available space" rules? I mean, if there is available space on the other drives it can use the other drives instead of the "sou
  4. My original plans for a new disk layout involved using tiered storage spaces to get both read and write acceleration out of a pair of SSDs against a larger rust-based store (a la my ZFS fileserver). This plan was scuppered when I discovered that Win8 Does Not Do tiered storage and I'd need to run a pair of Server 2012R2 instances on my dual-boot development and gaming machine instead. I'm currently using DrivePool with the SSD Optimiser plugin to great effect and enjoying the 500MB/sec burst write speeds to a 3TB mirrored pool... but although read striping on rust is nice it doesn't yield
  5. Good evening everyone. I found this very interesting, fascinating even: I had just set up a Windows 2012-R2 Storage Server, with ~20 TiB of drives to function primarily as a media server running Emby and file-server endpoint for various backups of machine images etc. CPU: Intel Core i7-4790K RAM: 32 GiB DDR3 2666MHz. OS is hosted on an M.2 PCIe 3.0 x4 SSD (128 GiB) *screaming fast*. 5 x 4 TiB HGST DeathStar NAS (0S003664) 7200 RPM/64 MB cache SATA-III Initially, the machine was set up with one large mirrored storage pool (no hot spares) composed from 5 primordial 4 TiB HGS
  6. I'd like to pool 1 SSD and 1 HDD and with pool duplication [a] and have the files written & read from the SSD and then balanced to the HDD with the files remaining on the SSD (for the purpose of [a] and ). The SDD Optimizer balancing plug-in seems to require the files be removed from the SSD, which seems to prevent [a] and (given only 1 HDD). Can the above be accomplished using DrivePool? (without 3rd party tools) Thanks, Tom
  7. I'm just starting to experiment with DrivePool, and I'm wondering how best to use it to optimize for speed. I've got the following disks SSD 256Gb boot/OS SSD 512Gb working drive - photography 1st tier HD 4Tb fastest - photography 2nd tier tier HD 1Tb ok - replication / read cache HD 1Tb ok - replication / read cache HD 2Tb slow - archive HD 2Tb slow - archive For the moment I'm just using drivepool for the spinning rust disks... and will use Samsung RAPID for my working drive - so that's out of scope for now. The rest can be in the pool - but by default * when I s
  8. I'm running drivepool on Windows 2012 R2. I noticed slower than usual performance on a share stored on the drivepool. I' utilized LAN speed test to test out some of my suspicions. I consistently get 800+Mbps/~100MBps on a share that is on the raw hard drive that is part of a drivepool. However when I do the same test on a folder in the drivepool (actually on the virtual drivepool drive), performance consistently lags down to 600Mbps/~70MBps. I've enabled all the Diskpool I/O performance options (network, etc...) Looking at the performance monitor on Drivepool UI, it shows its reading the
  9. Is it normal for the Windows Server 2012 Essentials Dashboard to become extremely slow and in some cases unresponsive when Scanner is scanning drives? Currently Scanner is checking the health of two drives simultaneously that are connected to separate SAS controllers. I am running the latest stable release of Scanner.
  10. Environment: Windows 8, 64 Bit - StableBit Drivepool 2.00.355. Four drives pooled into one pool. Shared over my G-bit network. Currently testing the latest release 2.00.355 I have following issue with data throughput. Copying large files (e.g. over 40GB) over my G-BIT network I have a no constant data throughput by writing the file on the pooled and shared device. Throughput falls and raises again in betreen of 70 to 115MB/sec. By watching the new perf. monitor I see the measurement of the file written into my pool for 2 to 3 seconds (with 115 MB/sec). After that time Drivepool shows no
