Can you mix SATA and SAS drives in RAID?
Distinguished. While you can use a combination of SAS and SATA hard drives running on the same controller, you cannot mix them in the same array. This means that if the hard drives are configured together in any sort of array, you would need to replace that SAS hard drive with an identical SAS hard drive.
Can I replace a SAS drive with SATA?
You can generally use a Sata drive in a SAS topology. you need to ensure the cable from the Sata drive to the sas controller/expander does not exceed Sata line length limits (circa 90cm or so).
Does SATA work in SAS?
The use of SATA hard drives on SAS controllers is made possible by the fact that both share the same infrastructure and have similar features. SATA drives may be plugged into SAS controllers. SAS drives cannot be plugged into SATA controllers.
Are SATA and SAS drives interchangeable?
SAS controllers can handle both SAS and SATA drives. SATA controllers cannot talk to SAS drives, only SATA drives. SAS connectors have an extra set of pins and a lockout feature, so SATA cables/connectors will not fit on a SAS drive. SAS cables, however, will work with SATA drives.
How many SATA drives does a SAS port have?
SAS controllers overcome this 1:1 port/drive constraint by leveraging expander technology. Instead of being limited to a maximum of eight drives on an eight-port SATA controller, an eight-port SAS controller supports the connection of up to 128 SATA and/or SAS drives per port.
Can a SAS drive be connected to SATA?
What is the difference between SAS and SATA drives?
While SAS drives are dual ported, SATA drives have only a single port. Another difference between the two interface drives is that while SAS is rated for a continuous enterprise use while SATA drives are normally rated for less than 100% duty cycle.
What are the benefits of SAS and SATA drives?
The one-two punch of the SAS/SATA value proposition is simple: SAS hard drives deliver the speed, reliability and scalability demanded in high-availability enterprise environments, while high-capacity SATA drives are ideal for bulk storage applications, combining low cost per GB and greater reliability and scalability than their parallel ATA ancestors. Complementary by design, SAS boasts the best performance/dollar while SATA offers maximum capacity/dollar.
Can I replace SAS drive with SATA?
You cannot mix SAS and SATA in the same array, so you wouldn’t be able replace SAS drives with SATA drives . You also cannot mix SSD and HDD, so you would need to do a backup/restore.
Which is better SATA or SAS?
Just what the difference between the previously used SATA and SAS can be seen is better signal integrity, greater device addressability, and higher performance with SAS. Point to point SAS technology currently gives a maximum speed of 3 GB/sec, whereas the maximum that SATA could achieve was 300 MB/sec, even with an improved SATA, called SATA II.
