What are some of the reasons you would have different drive types, sizes, and performance levels in your storage environment?
Check out our video featuring a conversation between Reliant Technology’s CEO, Reid, and one of our storage engineers, Michael with tips and tricks about the differences between different types of disk drives and how to choose the right type for your storage infrastructure.
At Reliant, we’re here to help you figure out ways to make the best decisions for your organization around your data storage technology.

Reid: Michael and I are in a deep philosophical conversation right now, talking about disk drive sizes. We’re talking about, why would you just not always add 600 gig drives, if they have the same IOPS as a 300 gig drive?
Reid: But they don’t, I guess.
Reid: Does every drive have about 150 IOPS or so?
Michael: Every SAS drive will have about 180. Every fiber channel about 150. When we get to Flash SAS, NL SAS, they change a little bit. 80, 90, things like that.
Reid: If they’re in that 150 range, would a 600 gig drive have 130 and a 300 gig would have 180?
Michael: No. Don’t confuse the capacity-
Reid: With the speed?
Michael: With the speed, right.
Reid: Why would you ever install anything but a 600 gig drive?
Michael: Maybe there’s a good price on them. That could be. Maybe there’s a good opportunity to add those. Maybe you’re repurposing. There’s many options to get different drive sizes.
Reid: I know on the used market there are different prices of drives. The higher capacity drives are more expensive, lower capacity drives are less expensive, so that’s a case in point. I just wonder if budget was unlimited if you’d always install one size drive, [inaudible 00:01:39].
Michael: I think so. I think you’re going to go for the mix of performance and capacity. I think if it’s an unlimited budget, with Flash being what it is today, it’s not new. It’s tested. It’s fully baked, so you’re going to have, in a perfect world, with an unlimited budget, you’re going to have a multi-tiered pool that’s going to have Flash SAS and NL SAS. That’s going to be the perfect world.
Reid: Just so everyone knows, NL SAS is the replacement for SATA drives. People say, “I want SATA drives.” Now it’s NL SAS.
Michael: Right. NL SAS.
Reid: What’s NL SAS? Near-Line SAS?
Michael: Near Line SAS is the new SATA.
Reid: The new SATA.
Reid: NL SAS is the new SATA.
