To RAID or not to RAID a basic workstation?

Greetings,

This is my first post to this forum. I am configuring an HP Z240 workstation through the hp store. Originally I set it up with regular 2 HDD's in a RAID 1 combination (as used in my present, 9-year old system). Speaking to a sales agent convinced me to switch to a PCIe boot-drive with a large HDD for internal storage. Here is the current configuration:


Windows 10 Pro 64
Intel® Xeon® E3-1245v5 (3.5 GHz, up to 3.9 GHz with Intel Turbo Boost Technology, 8 MB cache, 4 cores)+ Intel HD Graphics P530
HP Z240 TWR 400W 92 percent efficiency Chassis
16GB DDR4-2133 ECC (2x8GB) Unbuffered RAM
Operating System Load to PCIe
256 GB HP Z Turbo Drive G2 PCIe Solid-State Drive (SSD)
3TB 7200 RPM SATA 1st Hard Drive

Main question: I considered adding a second PCIe for RAID, but that configuration was not allowed. Some research showed that this is controversial, e.g.,

And apparently Software RAID 1 from PCIe to HDD is also a bad idea (performance loss):

http://www.tomshardware.com/answers/id-1855855/ssd-hdd-raid-type-setup.html#11798083

Redoing the setup with two regular SSD drives plus large HDD storage is also a not-allowed configuration.

So what are my best options for redundancy? If the boot/applications-drive fails, I'd like to be able to continue working until I can get it replaced. This has happened 2 or three times in the past nine years with my present machine, so I want to be prepared. What are the best practices recommended for someone in my position?

Minor question and comment:

1. My present system uses about 45gb in OS and apps accumulated over the years. Is 256gb overkill for the boot/applications-drive in this case? Is 128gb sufficient?

2. I don't intend to replace this machine for years to come. I'd like to reasonably "future-proof" the workstation without breaking the bank: Any other advice on my current configuration (purchase impending) is appreciated in advance. Here is the starting link for any interested in exploring:

Choose the "Customize" option.

Thanks in advance!

Honestly,

Install Macrium Reflect. It is free. Install like a second hard drive that is the same size as the PCIe drive. Then setup a schedual to have it clone drive to drive every night. You won't have the 100% redundancy of a RAID 1 in one drive failes (But honestly for ANY kind of NAND Drive RAID 1 is STRONGLY NOT RECCOMENED as they more than likely will fail at the same time (If failure is due to usage and not hardware flaws)

Setup the hard drive as your data drive. Make a RAID 1 of that if you want, then just have another drive be a clone of the other that gets cloned once or twice a day. This way, PCIe dies, you can boot form the HDD until you get the PCIe RMAed

Thank you very much for the reply. Questions:

1. Is it necessary to get a second hard drive, or can I set up a partition on the 3TB drive already included in the above configuration?

2. The HP configuration option does not have a 256GB hdd: Will a "500GB 7200 RPM SATA 2nd Hard Drive" work, or do the drives have to be the exact same size?

3. Is it correct to assume that restoring the replacement PCIe drive as boot with Macrium Reflect is straightforward?

Thank you again for your help and advice: I am happy that I waited for a response before purchasing!
 
1) for cloning you must have its own drive as it erases ALL partitions. If you were to Image it, and then use another machine or Macrium Recovery boot to then restore that image after replacing the PCIe drive then you can do a partition

2) As long as the destition drive can fit the data on the source drives (You have a 3 TB drive with 900GB of data you can use a 1TB drive or larger)

3) If you go from PCIe to HDD boot all you SHOULD have to do is change the boot drive. I have yet to work with a NVMe drive, but this works perfectly when using a SSD and HDD.

It appears that I now have sufficient information to finalize the workstation configuration. Thank you very much for your help, drtweak!
