I would remove the competitor's link before a Don pulls you up about it...

Simply write the make/model (without links)...unfortunately I can't really help you as I know sod all about SAS/SCSI's!

If those drives are Ultra 320 then that's not a SAS drive.

U320 format has been out for quite a while now.

15K SAS drives aren't cheap - much the same price as low-capacity SSDs.

Ah! thanks for the response. I was under the impression that sas and scsi was the same thing?
didnt realise ebay was a competitor either but ive removed the link

So, is it worth getting a 15k SAS for my windows partition or is it worth getting an SSD instead? Will there be a noticeable speed difference between the two?

 

[JamesTuc]

Oh, also, what would the difference be between a Raid 0 setup using 2 x 7.5k drives, a single 15k and an SSD?

 

[Le Samourai]

In general I'd say SAS should outperform SATA mechanical drives (SAS runs at full duplex, whereas SATA runs at half duplex - something like that?) but probably still won't compare to random access speeds of SSD. And, if you go for 15K drives the noise/vibration might slowly drive you nuts!

I was considering getting a few SAS drives to run on my LSI MegaRaid controller but there's a lot of vibration as it is with 4x7.2K drives - 15K would shake the floorboards!

If you want to compare prices:

The Seagate Cheetah ST3146356SS 15K 147Gb looks a good performer and is £145.
Power use is quite high for a single drive though (9.6W idle/14.4W).

 

[JamesTuc]

Ok thanks. I guess if I did get a 15k drive I'd dampen it using an elastic cord suspension method. I think I'm more likely to go for the SSD though, the overall price/capacity/speed seems better.

I have 2 SAS drives (300Gb 15K hitachi). I used them in raid and yes they are quite fast and a little noisey. Removed them some time ago when I went SSD.
Tried selling them on MM but no one wanted them. Have been sitting in my cupboard for months now.
