The Precision 7910 with 8 HDD bays = 4x 3.5" and 4x 2.5" bays.  The SAS controller on the motherboard should be able to support any new HDDs in the foreseeable future. The 3.5" bays should be able to use any commercially available SATA and SAS HDD size. The 2.5" bays are limited by the available size dives.  For traditional HDDs the current max is 5TB.  SSDs on the other hand are getting bigger every year.  If you want to pay for it you can get a 15TB 2.5" SSD
Hi, Could someone tell me what is the largest 3.5 SATA hard drive that can be installed in a Dell Precision T7910 workstation? Currently, I have eight decks of which three are occupied by a 500GB SSD, a 3.5 SATA 10GB drive and a 3.5 SATA 6GB drive. I would like to add a 12GB 3.5 SATA drive. My T7910 has 64GB of memory and runs on Windows 10 Professional. Your answers and help will be much appreciated. Regarding the hard drive I'm thinking of buy one of the Seagate Ironwolf drives. They seem to be highly rated. Unfortunately, they seem to come in many different varieties made for different purposes e.g. raid configurations or surveillance. I'm just looking for a regular drive to store data and backups. Any suggestions, advice and comments on what type of hard drive I should be looking would be very welcome indeed. I look forward to hearing from forum members and my thanks in advance.
