  1. What cards, what devices? For a given 10G network card (or 16Gb FC, 40GbE, etc), the limiting factor is the 6GB/s bandwidth through the PCIe slot itself. I've been able to push 20Gbs through two ports combined on network cards before. The trick is making sure your network settings allow it.
  2. Those figures will always change, although the way your utility is reporting on them is somewhat strange. Those figures count the total lifetime 512-byte read/writes... so they will always be changing as you use the drive.
  3. The cheapest thing that came to mind is the LSI 9200 series: http://www.ebay.com/itm/like/252140860944?lpid=82&chn=ps&ul_noapp=true Dell probably has an OEM version of it, but the LSI retail one will work. Just look for the one with the "e" in the name, meaning it has the external port.
  4. As much as I love Synology, in the price range you are talking about, you should really be looking at the NetApp AFF A200. Much, much higher real world performance than the FlashStation, which we had fully decked out in SAS3 Toshiba flash. Like night and day differences.
  5. Do you have a PCIe slot open? Most of those tape units require a external SAS connection on the computer you are connecting it to for communication.
  6. Thermal output is completely linked to power draw. If you draw less power you are going to throw off less BTUs of energy. No other magic but that.
  7. Crap, didn't see that. Thanks for pointing that out! Point still stands on the 2TB model.
  8. On SSD, before taking a jump in that direction, please research some of the corner-case support issues some have encountered with it: https://www.reddit.com/r/sysadmin/comments/609e98/another_catastrophic_failure_on_our_windows/ I've personally heard fantastic things about Storage Spaces Direct in regards to performance, but I think there are support issues that still need to be honed out. You just don't encounter the same scale of problems with other solutions out of the gate. On the all-flash side, I've been incredibly impressed with the NetApp AFF-series. I'm playing around with the A200 right now and its been awesome. Performance hit from inline compression and dedupe isn't that bad either.
  9. Both of those drives are going to be roughly in the same ballpark for noise. What platform will you be using and where will it be located? Rubber isolation to help with seek noise and just distance away from you will help the most.
  10. Fun benchmark... not bad. Performance wise though I've attached the Kingston. Incredibly terrible at low block size, and you can see the dips during the large block transfer sections.
  11. We used the stock driver. In every single case in the past where a custom driver is different, it had zero impact on mixed workloads. There might have been a small uptick in straight line numbers but that was it.
  12. Out of the gate the RAID card vs HBA (or the Intel chipset that we test with in our consumer platform) will chop away quite a bit of performance. Sometimes 2-3x. The 12Gb/s LSI based cards do have an HBA mode that can offer much higher performance than what you are seeing through that older RAID card. Even better is a straight up LSI 9300-8i HBA and sticking with software RAID in the OS.
  13. That RAID card you are using will never be as fast as a dedicated HBA or an Intel chipset connecting the SSDs to a SATA bus. So much of that bursty speed you see in a review would be lopped off by the 9260-based RAID card. What long term workloads will you be running on those SSDs? Since you did see our review I'm curious what pushed you in the direction of this particular model to purchase. It didn't response well at all in any of our server workload profiles.
  14. What SSDs specifically are you working with? That RAID card looks like an older 9200-series LSI model, which if you are using just hard drives or slower SSDs you may not see a difference.
  15. Either Samsung offering would be a solid bet. I'd run away from that Transcend drive. The WD offering should be stable and reliable, but not as fast as the 850 EVO. So my order would be 1. 850 EVO 2. WD Green 3. 750 EVO
