Seagate Backup Plus 4TB Drive - Cheap 2.5" 4TB drives

[Deslok]

Anything is possible. But the four failed drives are on three different systems, so very little common footprint. One system is on X11SRH-f MB SATA through an SM216A backplane, one is Xeon-D with build in LSI2116 connected on a SAS-2 expander backplane. The system with two failed drives has one drive on the MB SATA and the other on an LSI230808i, all direct connect backplanes. Four failed drives, three systems, four separate controllers. Nothing common at all.

You're right I was thinking you had one system when i asked that, that's what I get for skimming forum threads while writing and rebuilding a system...

Just sharing my experience. My conclusion to some of my initial failures were due to some issue causing the drives to drop out the array which resulted in corrupted MBR's and prevented a handful from being recognized. Once I recreated the MBR they were functional again.

any more on the ST5000LM000 drives? thinking of grabbing 4 for a "small" RZ2 array.

Good question. I was thinking about getting 2 to replace my 4TB parity drives so when I fill the other 6 slots I have free I can use the 5TB.

So far with the 4TB ones I have 8 in use right now with about 8700 hours on each of them with no issues. I am using unraid so it is not on really a raid array.

The 5TB model is on special @ Amazon for $106.99. An absolute ripper of a deal!

EDIT: Looks like it's over. Hope mine ship; guessing it was a pricing error.

2 more 4TB failed on me this week. I'm done with these drives. They are AWFUL in performance read is great, write is awful.

I'm replacing them all with the 5TB BaraCuda's that are rock solid. The price/performance is not worth it on these drives.

 

[sth]

are the Firecuda's SMR?

The Barracuda's I think MIGHT be. Which is what this drive is:

i'm looking for confirmation.

I'm gradually filling a SC216 with ST5000LM000's shucked from Seagate Backup Plus's. Just ordered #5. So far no issues of any kind. They run cooler and consume less power than 3.5 drives.

The $70 difference between the bare drive and the 2.5 5TB shuck drive is insane.

Might as well buy one extra just in case they die. Man i didn't know that these had them in there:

Curious to see performance compared to the ST4000's @Fritz please....

~10 months in and zero failures out of the 26 I have. They've been sitting at 25C since the day I've installed them with minimal load though.

I had 8 that ran for over 9K hours no issues. I just sold them as I went to 8TB drives. Other than parity syncs the load was pretty low on them.

Drivers for the LSI 2308 Mustang onboard controller are dated 1-29-2013. The driver download link on Supermicro website does not work. I DL'd newer drivers from Dell and HP websites but both fail to install. I can find nothing of Broadcom's site. Anyone have a link to the drivers???

I run mine HARD. Constant 100% I/O traffic with storage spaces. The 4TB's do minimal writes until I start doing redundant backups then the I/O goes to crap as Storage Spaces is replicating to other devices.

I could've had 2 bad drives, sure. I've got 2 others working without a problem. These drives are not meant to handle the constant punishment I put on them. long daily writes to the disk followed by simultaneous reads to backup drives.

Sounds like they're doing a pretty decent job of surviving if you're beating them into the dust 24/7

Here's a benchmark from one of my 5TB units (no data on it, mind);



Looks pretty good to me. Assuming it can keep up 100MB/sec or so, should be an 8hr resilver, which is plenty...

I'm planning to use 24 of these in a RAID 60 with two hot spares (11+11+2)... should be fun, 90TB of capacity in 2RU

Edit:

ATTO benchmark, also;

 

[Churchill]

The 5TB's are night and day better than the 4's are. I can tell instantly when I hit the 4TB disks as my IOPS plummets when writing to them.

 

[sth]

my individual 4TB benchmarked fine but fell drastically when put into a RAIDZ2 array, could you create a small Z2 array (6 or 8 drive z2) and get some benchmarks too please? thanks for the above reports

 

[neggles]

I only have the one drive right now - just picked it up for testing - but my next step will be a 6-drive array (both hardware and RAID-Z2 for comparison) so hopefully I should have some data on that soon.

I'm awaiting delivery of a SM CSE-219A-R920UB chassis, gonna be loading it with the 5TB ST5000LM000. So far bought only 1 drive for testing. I shucked it from externals. Haven't found any commands that will report the actual cache size on the disk. Does anyone have a freebsd command to print such info about a disk?

Also waiting eagerly on perf reports from other users here on the ST5000LM000 drives in a RAID setup.
Some single disk tests, performance in the lower stripe sizes seem unstable and vary from time to time:
