![]() As a matter of policy, Seagate does not publish attributes and thresholds. ![]() Each new design incorporates improvements that increase the accuracy of the SMART prediction. ![]() As a practical matter, the technology supporting SMART is constantly being improved. SeaTools does not analyze attributes or thresholds. Seagate uses the SeaTools diagnostic software to test the SMART status of the drive. When a SMART Status test has a FAIL it is extremely important that you back up all of your important data. SMART Status FAIL is a near-term prediction of drive failure and the drive usually functions like normal. Unfortunately, there is no way to specifically predict when the failure will occur, so your best response is to back up your data as soon as possible. Many computers automatically check SMART Status when they start up which is when most people become aware of the issue. If still under warranty, then SMART Status FAIL is a valid condition for warranty replacement. ![]() With the backing of personal computer manufacturers, the disk drive industry adopted an analysis system in the 1990's called Self Monitoring Analysis and Reporting Technology, or SMART. The idea then and today is to predict a failure before it happens. Various attributes are being monitored and measured against certain threshold limits. If any one attribute exceeds a threshold then a general SMART Status test will change from Pass to Fail. The current state of this technology is the result of more than 20 years of innovative Seagate engineering focused on self-testing. You said Seagete's SeaTools reports it's a ST4000DX001, and NewEgg says that's a Seagate Desktop SSHD ST4000DX001 4TB 64MB Cache SATA 6.0Gb/s 3.5" Solid State Hybrid Drive Bare Drive with apparently 8GB for the "hybrid" flash section ("NAND Type / Size" of "MLC / 8GB").īeing a "Bare Drive" I wouldn't be surprised if Seagate didn't have it in their retail drive warranty somehow, and the part number could be from whatever company bought the drive from Seagate & put on their own label.Serial ATA (SATA) disk drives are constantly monitoring and analyzing their own performance, integrity and environment. Any warranty issues in the future is all I'd worry about, if whoever you bought it from will do exchanges themselves that's ok, it sounds like Seagate won't automatically (through their webpage at least). If it does speed up, and passes all SMART tests & seems good, then it sounds like just a bad label, maybe from a weird 3rd party reseller. If F3 reports all's good, then trying to read the same few files (it uses 1GB test files, so read 3 or 4 of them) maybe 10 times in a row should convince the drive to put that data into it's faster SSD section, and increase read speeds from HD (150MB/s?) to SSD (750MB/s?). You'd have to watch out for the OS disk cache, and the size of the SSD section, apparently it's 8GB (see below), but I'd guess use maybe 20%-50% of the SSD size, and at least double your ram+disk cache? You could try reading the same data over and over, and see if the drive eventually moves it to the SSD & then starts giving insanely fast read speeds. I don't think there's many other tests to try, other than manufacturer's diagnostics & SMART data, the drives usually automatically pick what to put in the faster SSD section so there's no user or OS control over it, it's essentially a "black box." Now, is there a way for me to test if this drive indeed is a SSHD or just a plain HDD? Should be another 12 hours to go before I have the answer. I'm currently running F3 to see if reported disk size has been hacked.
