Seagate Exos X20 20TB Internal Hard Drive - 3.5 Inch Hyperscale 12GB/s SAS HDD, 7,200 RPM, 2.5M MTBF, 512e and 4Kn FastFormat, Low Latency with Enhanced Caching (ST20000NM002D)

SAS drives are hard to find on Amazon (I find the "SAS is not what I ordered" story hard to believe). Even when I put "SAS" in the search box, I get a whole bunch of recommendations for SATA drives. Ok, SATA is a reasonable alternative, but, it doesn't fit my use case. Anyway, this IS an excellent drive. It's not noisy (I don't know where this "it's noisy" myth comes from?); no it isn't - it makes a brief quiet buzz at boot up - whoop-Dee-do. Otherwise, It has a 2.5 *million* hour ttf. It is as fast an hdd as is available in 2024 and the capacity is just overwhelming compared to a farm of nvme's. It requires a cable connection to an HBA (that requires at least 4x PCIe) and a piece of tape for pin 3 (the auto shut down pin). It's not plug and play, but, it's not impossible for anyone.

Primero el disco se dañó y perdí muchísima información, me mandaron con Seagate para pedir una garantía, tuve que pagar envío y recepción y me mandaron un disco de mucho menor capacidad, ahora tengo que esperar de 2 a 3 días hábiles para que evalúen mi caso.

I have had some issues with Seagate HDDs in the past, but when you have plenty of drives, you will. I had been using WD for some time as the price was better and saving money was important for personal use. Then, I had quite a few of the WD drives start to fail. I had an enterprise HDD die just after the 5 year warranty ran out. Then, I had several WD Red NAS drives start to fail. Luckily, they were just still in warranty. I had 6 fail within a 2.5 week period. One of the replacement drives that I got, failed 2 days after installing it. I had to quickly do a return as I only had 3 days left before the initial warranty for the original drive went out. I had 2 more fail after the warranty had run out. I also had a run of bad luck with the WD SSDs as well. Both a M.2 style and a 2.5" SSD. The WD Blue went from 1% wear out to 100% wear out from just sitting in a system that was powered up. The drive was not initialized or anything. I never had so many drives fail on me like this ever before. Won't touch a WD drive again. Been using the EXOS in my TrueNAS builds and no complaints.

Was tricked on the mobile app and didn't notice that is was SAS and NOT SATA. Company wanted 20%-50% restocking fee which is crap. Not buying from this company again. Maybe they should put a SAS logo on their ONE image, if they had images of the connector ports I may have caught this. Wasted time trying to find a controller card and all the controller cards on amazon are from 2012 and no firmware support. Total garbage, go to a different page and make sure you get SATA. They also don't list SAS on the product information part of the posting.

I got a great deal on this drive at $120.The drive is incredibly fast, getting consistent 260MB/s transfer/burst rates (HDTune) and read/write speeds averaging 210MB/s (HDTune Pro).The drive does make a slight humming sound, but it's not as bad as I expected from a datacenter drive. The noise the head makes during writing is also not as noticeable as I expected.All in all a great drive with a long warranty and high speeds.
