Need to upgrade the HDDs in our server, it currently has 5 x 1TB HDDs (RAID 5 Array) in it running 4 server VMs. It's running out of space so I was thinking of upgrading to 2Tb SSDs but there's a huge difference in prices:
- Samsung SSD 860 Pro MZ-76P2T0B/EU £421
- Kingston A400 SSD SA400S37/1920G £155
- Crucial MX500 CT2000MX500SSD1 £186
Some are way more expensive than the Samsung, but I thought the point of SSDs was that they were inherently quicker and more reliable than an HDD so why such huge price variation? And what should I be looking to buy?
