Tried to build a RAID array 3 times, disks failed every time. 1/25/2020 11:29:54 AM

Pros: Cheap

Cons: Cheap.

Overall Review: Tried building a raid array with these. They failed while formatting every time. While they were the cheapest 8TB drives out there, they are that cheap for a reason. Come to find out they use SMR technology, Stay away...

Garbage "SMR" Drive 1/16/2020 5:03:03 AM

Pros: None.

Cons: This drive utilizes SMR technology, or Shingled Magnetic Recording. Seagate won't tell you this, but the dead giveaway is the 256M of cache. The "generous" increase in cache from 64M to 256M is not to increase performance, it's a pitiful attempt to try and prop up the abysmal performance of SMR platters.

SMR platters orient the magnetic bits like roof shingles on a house, where rows overlap each other to try and squeeze more capacity out of a platter. The problem is that the write head cannot physically be made small enough to write a single bit of data, so data writes are destructive to data bits around it. This means that the drive must perform housekeeping to re-write the damaged data, and the large cache is used to both do this task AND hopefully hold buffered data that might be requested by the host machine.

In practice, this doesn't work at all. The numerous reviews where users complain about I/O errors and timeouts are because the drive controller can't keep up with normal usage patterns and is falling flat on its face. Sequential writes suffer and random writes are slower than 30 year old SCSI drives once the limited cache is exhausted.

The ONLY use case for SMR drives is infrequently accessed backup storage. These drives are not capable of being used as a primary drive in a system, nor as a secondary storage drive where you might store large programs like games. As other users have said, both Windows and Linux will act like the drive is bad because the drive is so slow to respond to anything that they give up.

Seagate isn't the only company guilty of using SMR, Western Digital also uses it on some of their drives, buyer beware.

Overall Review: SMR is an awful technology likely used by mechanical drive manufacturers to keep up with the ever decreasing cost of solid state storage, but it's come back to bite them.
