Hello again folks, Setting up a 4 drive RAID 0 for video editing. I'm aware of the risks of RAID 0, all of the media loaded on to this RAID will be backed up in triplicate prior. The purpose of this unit is to be big and fast (both read and write) above all else. This unit will store almost entirely large files. All small files like projects and graphics will be in the cloud, and cache files on a separate SSD. I'm using a Highpoint RocketStor 6124v enclosure with four HGST HC320 8TB drives (32TB) I'm of the understanding for large files it's best to go high for all values so I have set the RAID to: - Block Size = 1024k - Sector Size = 4k - Allocation Unit Size = 2MB Both HDTune and BlackMagic Speed Test seem to give slow, presumably inaccurate values when run. CrystalDiskMark throws up numbers more in line with what I'm expecting so hopefully it is accurate. [Read] Sequential 1MiB (Q= 8, T= 1): 784.370 MB/s [ 748.0 IOPS] < 10671.94 us> Sequential 1MiB (Q= 1, T= 1): 491.741 MB/s [ 469.0 IOPS] < 2130.65 us> Random 4KiB (Q= 32, T=16): 6.806 MB/s [ 1661.6 IOPS] <236063.82 us> Random 4KiB (Q= 1, T= 1): 4.501 MB/s [ 1098.9 IOPS] < 907.97 us> [Write] Sequential 1MiB (Q= 8, T= 1): 1002.416 MB/s [ 956.0 IOPS] < 8332.63 us> Sequential 1MiB (Q= 1, T= 1): 264.777 MB/s [ 252.5 IOPS] < 3952.77 us> Random 4KiB (Q= 32, T=16): 11.996 MB/s [ 2928.7 IOPS] <171486.64 us> Random 4KiB (Q= 1, T= 1): 8.081 MB/s [ 1972.9 IOPS] < 505.79 us> Profile: Default Test: 1 GiB (x5) [Interval: 5 sec] <DefaultAffinity=DISABLED> Date: 2020/09/16 0:47:11 OS: Windows 10 Professional [10.0 Build 19041] (x64) I'm confused as to how I'm getting faster writes than reads out of this unit. It's advertised as topping out at 1000MB/s which is true for writes but reads seem slow by comparison at 784MB/s Another mystery is that the Highpoint software lists Read Ahead and Write Cache as not supported with these hard drives? And no Write Cache Policy looks to be available for the RAID Controller. But write caching is enabled in Windows for the RAID volume under policies. Not sure if this makes a difference. I tried it switched on and off while benching and it didn't impact the numbers. Aware also these are only synthetic numbers, and that my real world use case is wanting to be able to very quickly transfer new footage to this unit as it comes in, and then have snappy response time while editing, please let me know if you think I should modify these settings before I start to populate the RAID with data.
