Six Things To Consider About The TrueNAS Z50 TrueFlash** Recently Dell announced an all-flash version of their SC4020 Array that they position as more economical than other All-Flash Arrays. In this article we cover six ways that a TrueNAS storage array is the real storage disruptor and explain where TrueNAS provides better value than the Dell SC4020. ### **1. Superior Performance Resources** - More CPU/RAM = More Performance (Dual Intel Xeon E5s vs. One E3 and 64GB vs.16GB) - OpenZFS self-healing file system ([Learn](http://www.onlinemeetingnow.com/register/?id=pmsy0fu2ck) why you should use OpenZFS) - Unified SAN/NAS (Dell requires a costly NAS gateway) ### **2. Supports I/O Intensive Applications** - Our SSDs are rated for three full drive writes per day ### **3. High Reliability** - We use enterprise SSDs¹; Dell uses consumer grade flash in their SSDs ### **4. Preferred Support** - Unparalleled & award-winning US-based support; Dell offshores many support calls ### **5. All-inclusive Feature Licensing** - File and block protocol support – File protocols are not available on the SC4020 - Unlimited, space-efficient snapshots – Dell supports 4,096 locally and 1,024 remotely - OpenZFS end-to-end data integrity capabilities – Dell’s block-only architecture depends on the client file system, such as those provided by Windows or Linux, for data integrity protection ### **6. Superior Density ** - 1.3x – 5x Denser – For 300TB of storage capacity2, TrueNAS consumes 3U, Dell consumes 14U³ [![Dell Blog 1](https://www.truenas.com/wp-content/uploads/2016/04/Dell-Blog-1.png)](https://www.truenas.com/wp-content/uploads/2016/04/Dell-Blog-1.png) Learn more about the TrueNAS architecture [here](https://www.ixsystems.com/wp-content/uploads/2015/07/TrueNAS_Overview_WhitePaper_WEB.pdf).
