What about software RAID5?
Yes, the place you install ESXi has nothing to do with how you can setup a RAID array.
You just have to make sure that any RAID card you buy is on the compatibility list on the VMWare website.
Generally, the cheaper RAID cards will only support RAID 0 or 1. For RAID 5 or 6 you'll need a card with Battery Backed Write Cache (BBWC) or Flash Backed Write Cache (FBWC) and these are generally pricier.
RAID 5 is not worth doing with the large drives we have today. If anything it risks your data.

RAID 1 for data protection, RAID 10 for data protection and performance.
guess RAID5 is out the window then

Honestly, you shouldn't discount RAID5 on account of a 7 year old article, purporting doom and gloom 5 years ago - that never happened.
If you're discounting it on account of hardware cost then that's completely fair.
Software RAID has been mentioned, and is doable - but I'm not a big fan. The processor in the microserver isn't the speediest, and I don't know that I'd want to be throwing RAID parity calculations it's way as well as everything else.

is it just out and out duplication?
I.E if I have 4 x 3TB disks and chuck on 6TB of files, the disks would be full?
I'm seriously considering this so just want to get my facts straight.
Not aimed directly at Easy, so anyone else who has experience of this product is welcome to chuck their penneth in![]()
Seriously, as an IT consultant I work with storage arrays all the time. I can tell you first hand just how many customers come to me with failed raid 5 arrays asking me to find their documents. It's too risky. The time it takes for the parity bits to rebuild the array is significant and more so as drive size increases. During that time you are a sitting duck for another drive failure and it really does happen.

It basically pools all of the drives into a single storage pool, there is no encryption or file splitting, whole files sit on NTFS drives, so worse can you can pull a drive and still recover data. There is duplication at a share level, you can simple tell a folder that you want it to be duplicated and it makes sure that folder is on more than one drive.
Scanner checks drives and alerts you of impending doom.
Understood, and that sounds like people who have relied on RAID as a 'backup', and they deserve everything they get.
Your point was made much better in your post than by that somewhat sensationalist zdnet article, so thanks for clarifying.
For home, and probably to an extent small business, people will want to get the most out of their investment. Losing half their purchased disk space to RAID1 or 10 can be a tough sell, especially as the array grows in size and you have to buy 2 disks whenever you wish to expand. Whereas losing a single disk worth of space seems like a fair compromise.
I can't disagree with any of your points, but 'too risky' is a variable the customer (In this case a dude on the internet we'll never meet, have to support, or be paid by for consultancy) has to define for themselves.
In my case, as an IT professional I understand all the risks inherent and have decided RAID5 is fine for me - it may not be for everyone.
Looks like Serverplus has gone back upto £127 with the 3yrs warranty, still £97 without though.
