Review: desertcart sucks - Product works great. Luckily I didn't get stuck with one of them fake ones that desertcart had on their site
Review: Runs Hot - high DOA rate - price increase instead of decrease 20mo later? - These 20TB drives are slowly replacing my 10TB HGST Drives in my RAID-6 configuration. 1st drive went without a hitch. 2nd drive also good (server is hot-swappable w/auto RAID rebuild; super simple replacement). 3rd drive could NOT be recognized. Sent back as DOA. Installed the replacement w/o an issue. Noticing at this point that ALL these drives run close to 105-106 deg. 4-6 deg hotter on average than the 10TB HGST drives. Hopefully this won't become an issue? Will be installing the last drive this week (4th drive of five). Will update after system reconfiguration to take advantage of the capacity doubling. Update: 4th Drive is also bad. Sent back DOA. If the DOA replacement (for the 2nd time) is good, that'll mean two of six drives were bad. 33.3% DOA rate... How do you feel about that? Keep in mind that these are NAS drives, usually in a large RAID array, so everytime one is replaced/upgraded the RAID must rebuild. A large RAID means a long rebuild time. And if the drive is bad, you have to put the old one back in (in case of an upgrade) and the array has to rebuild anyway. Whats worse, if you're NOT upgrading, but instead repairing, now you've got a degraded array for a few more days with doubts that the replacement drive will work? This situation sucks. Regarding my earlier comments regarding running hotter - these 20TB drives, after examining the label, consume just over 50% more power than the 10TB HGST's that are being removed/upgraded. This choice may have been a grave mistake. Thank God I initially setup a RAID 6 as opposed to a RAID 5 or I'd be on pins and needles. Remember, these drive are data rated for how much data they can read/write in thier lifetime. This rating, if even accurate, is getting chewed up every time there's an array rebuild (including the rating on the existing working drives in the array). Unhappy situation. Perhaps Western Digital was the better choice? EDIT 7/25/2023: Yup, 6th drive worked. All four drives have now been replaced/upgraded. Two of six were DOA. That seems ridiculous to me. RAID has rebuilt 100% and now is under expansion to take advantage of the capacity doubling (these drives are 2x capacity of the drives they replaced), another 53hrs. I'd be done by now if it weren't for the DOA drives. Now I have to live with the constant worry of possible pre-mature failure. I mean, based on the increased heat and the DOA rate, what would you think? EDIT 3/20/2025: The 4 of 6 drives that worked are still working 20mo later. They are still selling these exact drives, but now for 15% more 20mo later?
