How do I find my SATA hard disk version?

ddenial · 11-27-2019, 05:10 AM

Hello

I've a PC, which is more than 10-15 years old. A year back I upgraded my motherboard which had both SATA v2.0 and v3.0 slots. I plugged my old SATA HDD to the v3.0 slot and DVD-Drive to the v2.0 slot. I'm pretty sure this old HDD is not a 6 Gbit/s (v3.0) drive. But still, I want to check what SATA version it belonged to (v1.5, v2.0 or v3.0)?

I can open the box and find it my self but want to know through the terminal, so that I can apply this knowledge elsewhere also.

This is my HDD info as seen by Linux kernel

Code:

$ dmesg | grep SATA | grep 'link up'
[    1.026647] ata1: SATA link up 6.0 Gbps (SStatus 133 SControl 300)
[    1.026675] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300)

$ sudo smartctl -a /dev/sda | grep '^SATA'
SATA Version is:  SATA 3.0, 6.0 Gb/s (current: 6.0 Gb/s)

$ sudo hdparm -I /dev/sda | egrep "Model|speed|Transport"
	Model Number:       ST31000524AS                            
	Transport:          Serial, SATA Rev 3.0
	   *	Gen1 signaling speed (1.5Gb/s)
	   *	Gen2 signaling speed (3.0Gb/s)
	   *	Gen3 signaling speed (6.0Gb/s)
	   *	SMART Command Transport (SCT) feature set

How to find what SATA version my Seagate HDD is (1,0, 2.0 or 3.0)?

Thanks

Have you tried Googling ST31000524AS?

It'll turn up the .pdf spec sheet here.

Strange, when I bought this HDD, there was no such thing as SATA 6 Gb/s in the market. According to pdf, it's 6Gb/s disk. Mine never crossed 90-95MB/s.

Code:

$ dd if=/dev/zero of=testspeed.dd bs=4k count=262144 conv=fdatasync
262144+0 records in
262144+0 records out
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 13.1187 s, 81.8 MB/s

6Gb is the possible speed from memory to disk drive cache.

90-95MB/sec is a good speed for sequential access, reading/writing from cache to the actual hard disk.

It will be much slower for random access.

This is bonnie++ result of this old HDD.
