  • Great drives for a great price.
Running great in my home server - 2 running in RAID 1. These hard drives are installed in 5.25" bays with 3.5 -> 5.25 converters. Running quiet and consume about 5-7W each. This item comes with the drive only and no mounting screws, so make sure to buy your own mounting hardware.

  • Great drives, good smart, no errors
Bought 5 of these a couple weeks ago. So far so good. I ran all the smart tests and 1 round of badblocks random pass; no errors, smart is all clear. Using them in a Truenas pool, currently zfs sending a large dataset over. Truenas monitoring shows writes around 250mb per drive though the data is transferring around 100mb per drive but that may be due to the overhead of zfs send encrypting data in transit then decrypting and writing data + parity however it does it. I’ll run some actual pool speed tests once transfer is done. I’ve bought from server parts deals on eBay plenty of times, never got a bad drive from them. It doesn’t say it in the Amazon listing but hopefully they’re normal warranty applies to drives bought from here too, though I doubt I’d ever need to use it. ... show more

  • Reliable CMR drive
Copying a bunch of videos and photos (~300GB total) from my SSD on Windows 11 shows around 260 MB/s speed on average, though it's a somewhat variable. I wonder if the fluctuation is caused by Windows or the drive's internal RAM doing some caching to optimize speeds, but the overall speed is good at around 260MB/s. My drive showed very low usage upon inspecting its SMART metadata, having about only 24 hrs of power on time and a few power cycles, so it's very new. Great value especially given the rising SSD prices these days. ... show more

  • So far so good in my home Unraid Server. 0 SMART errors
So far so good in my home Unraid Server. I have two of these (ST28000NM000C) running in my array, and they currently have over 2,400 power-on hours (~100 days of 24/7 uptime) without a single SMART error. They also run surprisingly cool in my chassis for being massive enterprise drives, sitting comfortably between 42°C and 46°C. I originally paid $549 for these, which was an amazing ~$19.60/TB for a new 28TB CMR helium drive. Seeing the price spiked up to $750 now just months later is wild. If you can catch these on sale anywhere near that $550 mark for a NAS or server build, don't hesitate. At $750, it's a tougher pill to swallow, but the drives themselves are rock solid. ... show more
