August 17, 20196 yr Hi, I recently came across an AIC called a flash accelerator (flash cache). I was wondering if something like this could be used as unraids cache disk. Is it viable? Is there benefits/drawbacks to doing so? The price/GB is insanely cheaper.

August 18, 20196 yr Community Expert Are these examples of currently available products? https://www.newegg.com/samsung-960-evo-1tb/p/N82E16820147595 and https://www.newegg.com/intel-750-series-400gb/p/N82E16820167359 The first, I believe, will work if you get a board with the appropriate NVMe socket for it. But I have not seen any MB's with more than two sockets. The second one would require the proper PCIe sockets and the proper configuration of the PCIe busses for maximum throughput.

I just wasn't sure If they weren't an absurdity large a volatile cache or something. Labeling a storage device as memory did cause a bit of uncertainty for me. Seems likely probably went with the name since they're intended to be used as cache. I appreciate it.

There is a review here from 2013 so the ebay drive linked, may well of had upto 6 years of use. https://www.storagereview.com/fusionio_iodrive2_mlc_application_accelerator_review_12tb Also a modern nvme drive such as the samsung 970 evo plus is a faster drive. Also the Fusion-io ioDrive2 may well run under the published specs for the drive unless the PCIe power limit threshold is raised from the standard 25 watts https://www.dell.com/support/article/uk/en/ukdhs1/how12260/setting-the-device-wattage-level-on-a-sandisk-fusion-io-iodrive2-to-improve-performance?lang=en Also take into consideration that the 970evo nvme 1tb drive uses only 6 watts.
August 22, 20196 yr Author Thank you for the replies! I'm trying to look at older AIC's rather than newer models, I am trying to fond the best price to GB ratio that can perform better than just writing to disk. I currently have an 800 GB SAS 3 Seagate nitro, but it bottlenecks the server hard due to the nature of my absurdly large file transfers. I was hoping to find something of at least minimum 1.6 TB, in a reasonable price range.
