hard drives Performance increase?

[Nexblitzer]

So just for a YOLO thing i was thinking about buying a singular SAS drive for redundancy because i only want small storage for some games and am not fussed on creating a RAID array. Any how i have heard other then being more redundant then usual SATA drives, they are also faster and better for use cases where multiple clients are accessing data at once.But just how much faster are they compared to a consumer/NAS drive? And don't i need some special adapter to make it work on normal PC's?

 

P.S ( Yes i know it would just be better to buy a NAS drive but i ave a lot of normal drives and want to have something different for a change )

SAS just has some build in error correcting. Other then that its mostly the same to SATA. The extra speed comes from the fact the drives spin faster, 10k rpm and 15k rpm. Yeah sure, SAS has a 12Gb link but the hdd's don't make use of it. You'd have to use SAS SSD's for that. Which as you might guess are a bit more expensive then normal ssd's.

Not calling you out or anything but i am pretty sure that if a SAS drive had 12GB/s potential speeds, it would be able to reach those speeds as they are being used with thousands of other drives in data centers. Ans SAS ssds? i am pretty sure you could buy a cheap house for less then those things. they are crazy dear. but how much speed are we talking here? Half of the theoretical 6GBt/s speed or what?

Just get either a normal hdd, or buy a QLC SSD, those are pretty cheap.

 

Also you can't connect Sata to SAS (unless your pc sata ports support sas protocols); so unless your pc has a SAS port your plan ain't going to work.

What do you mean by this?

The drive or interface in and of itself doesn't have anything to do with redundancy.

That is not related to the interface (SATA vs SAS) but rather the drive itself.

10K RPM drives usually has shorter seek times than 7200 RPM drives and therefore more suitable for multi-user workloads, but that's about it. It's not because of the SAS interface.

Entirely depends on the drive. The interface itself doesn't matter that much.

You do. You can NOT connect a SATA cable into a SAS drive. SATA drives work in SAS ports (with adapters), but SAS drives do not work in SATA ports (unless the drive and controller has a non-standard/optional SAS drive to SATA controller function).

 

 

Just go with SATA.
