which one is faster ?

im looking at hosthatch specs:

Linux:
Dual Quad Core Xeons (2x2.66GHz)
512MB Guaranteed Ram
100GB Raid10 SATA HDD Space
2Gbit Unmetered bandwidth

Vs

Windows:
Dual Quad core Xeon (1 x 2.66 Ghz)
512MB DDR3 Guaranteed Ram
20GB SAS15k space (Very fast space!)
2Gbit Unmetered connection

way faster....

i have Raid10 SATA HDD its not that fast.
 
SAS15k will be faster then Raid10 SATA, but it depends for what you will use the server as well as 512 MB for Windows, it is not enough.
 
Im more interested in Windows one ;) 512mb ram and 20gb space (10gb free after OS) is the major down point.

btw for extra $8 i can bump the ram to 1gb :)
 
Hey Am21,

I just saw this thread and wanted you to know -

SAS15k drives are very, very much faster than the SATA ones. We get around 250-350MB/s disk I/O on the SATA ones and 500-550MB/s on the SAS15k ones.

About the 10GB being free after OS, that is because you chose Windows Server 2008. I would recommend you either upgrade your space (10GB extra - $5 extra) or choose Windows XP as your OS as Windows XP is small and you'll get around 17GB free space when the total is 20GB.


Thanks!

Try to think Carefully Here

Your an Encoder

BR Rip = 4GB (Lowest Quality) ==> Encoded to 700MB
You're Happy (Space used @ the time of encding 4.7GB)
softwares around 300MB (5GB now)
5 Left
New MOViE Kept on download while its encoding 4 GB more
19.7GB it will affect all the jobs on RDP coz of low disk

+ Very Low Space for backups of DMCA reported Movies

Is the RAID10 hardware or software RAID? That can make a major speed difference as well...

In any case, SAS will probably be much faster - but RAID10 is the way to go if you want to ensure your data will be safe. If there's no RAID and a drive goes bad, your data is gone.

Yeah speed wise SAS will perform a little better than Sata even without RAID for a single file etc. But hardware raid will come handy when multiple users accessing different files at the same time.
 
Almost the same

Here is the test

4X1TB Sata II w/ onboard raid 10:
Code: 
[root@server ~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 8.95496 seconds, 120 MB/s
2X300GB SAS w/ hardware raid1:
Code: 
[root@server~]# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 8.94611 seconds, 120 MB/s

Lol, most of the replies here are incorrect.

Depending on the drive model and SATA/SATAII/SATAIII, you can actually squeeze better performance out of a RAID10 array of SATA drives in comparison to a single SAS15k drive.

Of course, if the SAS15k drives are in RAID10 too then they'll beat SATA hands down, at any given point in time, every time. But SATA2 in RAID10 vs a single SAS15k will result in the RAID10 array performing better. You're gaining advantage on reads and writes in a RAID10, so you have to keep that in mind too.

Oh and SSD tops them all ;)
