ST4000VN000 CRYSTAL DISKMARK UPDATE
So all in all very happy with the drives so I'll update my rating but still critical of the packaging. Hitachi drive although being 7200rpm and having better transfer rates was more expensive and to be honest the extra performance would be wasted in my Microserver as it just streams to the TV's/PC's etc in the house. The Red's seem to have a few issues with the early drives failing and the These are the first Seagate drives I've bought in a long time it was a choice between these, the WD Red 4TB and the Hitachi NAS 4TB. Performance wise the drives are fine, faster than the 2TB WD Greens they replaced with about the same power draw looking at the specs. Uncorrectable Sector Count : This can indicate an issue with the discs themselves of the heads that read them.Įxcept for a few SMART items where the raw info was not correct (manufacturers set up their drives differently so apps can have issues reading the raw data) all the info was fine with almost all zeros. This can be an early sign of issues with a drive.

Reallocated Sectors Count : If the drive finds a error with its read,write or the verification it does it will mark the area and move the data to another area on the drive.Ĭurrent Pending Sector Count : If an area of the drive failed but the next time it was accessed it was okay it's recorded here as it may be unstable and need moving.

Then I ran a full health and error check with HD Tune Pro (downloaded the 15 day free trial version as the freeware version has a 2TB limit on volume size).Īll of the SMART info checked out OK the critical ones to check seem to be: Well the drives had survived, ran a full error check on both drives with Seagates own utility ( not very informative as just gives a pass/fail) but Just waiting for a backup to complete on my sever before I can test the drives out and see if they survived. The proper brown cardboard boxes with the plastic end covers/supports or the foam lined boxes we used to get with hard drives ? Two drives in antistatic bags in a box with a bit of crumpled brown paper !! What happened to
ST4000VN000 CRYSTAL DISKMARK UPGRADE
Unfortunately I found no way to issue it through GUI, thus the need to use command line:Įdit: nest post will be about a proper way to upgrade the mirror.Arrived this afternoon, drives look okay which is surprising considering the lack of any kind of protective packaging. If disk still works after 30 days, you can remove one of the older disks. Also all I/O operations are duplicated to 3rd disk and early failure might be detected. In the meantime not only old files are copied to the new disk.
I am a proponent of a different approach. In a nutshell it recommends to take one disk offline and to add another thus replacing the first one. This post outlines the steps involved in maintaining the mirror. I click Disk\Format, select da4 and specify ZFS.ĭiagnostics\Information\Disks for da4 looks like this: I edit it to: set APM to 127, activate SMART. New drive da4 immediately appeared in Diagnostics\Information\Disks.ĭa4 appears. I powered down the system, installed new hard drive - there are plenty of empty positions available in the drive cages, powered the system up. This time I will document the procedure and will try to stay away from command line. Then after 30 or so days I will use these hard drives to upgrade mirror tank. I plan to purchase two 4TB drives to upgrade mirror vault. My NAS is configured with two mirrors for file sharing (over SMB) with other Windows computers: Maybe will use synchtoy to backup one drive to another. So I will be sticking with two single hard drives. For a workstation use scenario this makes storage spaces unacceptable for me. Random write performance however is dramatically deteriorated. Transition to storage spaces mirror moderately improves sequential read speed. Here is what I measured using CrystalDiskMark 3.0.3 圆4:

A Microsoft Windows 8.1 Storage Space with two of the above hard drives configured as mirror.Kingston SSDNow V300 Series SV300S37A/120G 2.5" 120GB SATA III SSD - just because it was already there.I compared I/O performance of three drives: I just learned about Microsoft Storage Spaces and throught I would give it and ReFS a try. Would be nice though if I could use those in a mirror - to make sure things are fast and tolerate hard drive failure.
Given that I am running out of space on my video editing workstation, the choice was clear.
After NAS mirror upgrade I ended up with two spare Barracuda 7200.14 hard drives.
