In Hard Drive

Lots of Space Works Great

S.M.A.R.T. shows brand new drive Full Seagate warranty

Installed it into an external drive connected by ESATA. Works fine

GREAT SO FAR - GIVE ME 6 MONTHS WITH IT AND WE WILL SEE

Pros: The Seagate Ironwolf 16 TB HDD is spacious, robust for a platter drive, and dense with a cache of 256 MB and a speed of 7,200 RPM on a typical SATA III power and data connection. You can really tell the platters are packed tight as this drive is a couple pounds or at least feels like it. Upon formatting in a Windows 10 x64 machine, this drive offers 14.5 TB usable. While this drive is intended for a NAS environment, I always utilize drives in a JBOD environment with manual RAID 1 so as to be more selective over data. On power-up, this drive is significantly louder than others I’ve owned, probably due to the seek arm aligning; however it presents no issue after a couple seconds. Reads: This Ironwolf drive performed surprisingly well in all read tests I ran on it. Utilizing HDTune, speeds started around 270 MB/sec and eventually fell to 125 MB/sec at the end of the platter structure. Access time was in the 14-16ms range with CPU utilization of 8-9% on a 7940X (14-core) system. Bursts were nearly at 500 MB/sec, however the cache fills quickly on a large transfer. Placing photography work on this new drive, it’s performed very well, and while not at the speed of an SSD, the cache helps to speed up short term data. This makes it feel at times like an SSD since my particular work is serial. Manually upping the queue / threads beyond 2 starts to make any performance metrics dip seemingly square to the amount of requests, though giving this drive many small files makes performance quite impacted. For an as-expected NAS environment though, most users are requesting a mix of files or larger transfers and I saw no issue with that given an expected performance drop. In Crystal DiskMark x64, this meant a sequential read of again, over 200 MB/sec; around 230. Yet any 4K data (where traditional HDDs struggle) relegated this drive to sub-2 MB/sec performance. As usual, if you need high performance on many tiny files, go SSD / NVMe. Writes: The writes on this drive proved similar to the read levels. Transfers start off fast, reaching around 250 MB/sec at the start of the platter, then falling in toothed fashion down to 125 MB/sec at the end. Bursts clocked in just under 300 MB/sec for writes which is very impressive for a platter drive. Access time was about 5-6ms, with identical CPU usage. Crystal DiskMark x64 echoed similar results as above, with writes reaching a generalized 250 MB/sec, yet at 4 KB file size, falling to 2.5 MB/sec. In sending over large amounts of data to this new working drive (over 5 TB), I saw the cache benefit greatly with video files and other large pieces of data, far exceeding typical transfer rates. Sometimes I’d see bursts to this drive at over 1 GB/sec, holding for a few, then moving down to the 200 MB/sec range so it simply depends on what you’re writing to this drive in terms of file make up to accurately gauge performance.

The IronWolf is rated as an NAS drive. I used them in an attached external drive in Raid1 for important video content I couldnt afford to lose. I cant speak to longevity but Im confident they will meet and exceed my expectations.

256mb cache quiet low heat

Reliable Cost-effective only when on sale. Runs cool.

-Very large capacity -No noise -Easy to set up

- An awesome amount of storage for the money spent - Outstanding performance for a mechanical device

It is well made, my M.2 SSD fit in it in seconds. It really is tool-free. It has an aluminum cover for heat dissipation. Installing one sized SSD will not prevent you from swapping it out for another later.

Works as intended Price was right Replaced an older failed drive Fast RAID rebuild with new drive

Performs well just as expected very fast right speeds

For the price, this enclosure is probably the best, especially since it uses the favorable realtek chip. I'm getting over 1k read and write speeds during crystaldisk Mark, and in real world about 800 mbp/s transfers via 1tb nvme ssd.

Works great, had a dead drive, but the three others I got were great. Trouble free replacement on the bad drive. Glad I bought from a reputable source.

Very nice , small just what I wanted

Shipping was on time. Package seemed to be in good condition. Even arrived on a rainy day, which was great to backup while the weather was wet. Ran a Self Test on the Drive everything seemed to pass. I didn't monitor the speeds, but it took almost half the day to back up 4tbs of Data. Synced it and took a nap. 8tbs for 110$ is a solid grab. Limited to 2 per person- saved me money because I would of bought more.

I have many (~20) of these WD Elements (8TB, 14TB, 16TB, 18TB and now 20TB) for the last 10 years. So far so good. They are fast and quiet.
