I'm configuring an HP Z420 workstation with a 1TB SSD system drive (Boot /OS Drive) and two Enterprise 4TB SATA HDD for storing all my data in RAID1 . I wanted to know what the best RAID1 configuration would have the best performance for how I will be using it.
I mostly will use the workstation for document editing (word, excel, PDF, PowerPoint, Visio, etc.), internet , watching videos.
I plan to store A LOT of personal photos (thousands) in RAW format (each can be 15MB to 40MB) on the 4 TB RAID1. I do some minor photo editing on photos using Google photos and I also store personal video files as well. I rarely edit videos and they are usually no more than 15min long but I do have a few longer than 1hr.
The workstation has the following RAID CARD:
LSI Logic SAS9260-8I SGL -8PORT, Int 6GB SAS/sata, Pcie 2.0, 512MB RAID Card WITH a battery backup on the card itself. I also have a UPS for the computer as well.
The RAID configuration page has the following options (Image attached):
- Raid Level (I chose RAID 1)
-Stripe Size ( the options here are- 8kb, 16kb, 32kb, 64kb, 128kb, 256kb, 512kb, 1MB)
-Access Policy (RW is the default)
-Read Policy (options here are- Normal or Ahead)
-Write Policy (I chose Write Back with BBU since I have the Battery backup unit but other options are Write through, Always write back, write back w/ BBU)
-IO Policy (Options here are- Direct or Cached)
-Drive Cache (Options here are- NoChange, Enable or Disable)
-Disable BGI (options here are- Yes, or No)
-Select Size (Here I'll be putting the whole 4TB to use)
Thank you in advance, I appreciate the help!
