The Seagate BarraCuda (500GB) SSD Review: Getting Back In The Game
by Billy Tallis on December 7, 2018 8:00 AM ESTAnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test. These AnandTech Storage Bench (ATSB) tests do not involve running the actual applications that generated the workloads, so the scores are relatively insensitive to changes in CPU performance and RAM from our new testbed, but the jump to a newer version of Windows and the newer storage drivers can have an impact.
We quantify performance on this test by reporting the drive's average data throughput, the average latency of the I/O operations, and the total energy used by the drive over the course of the test.
The Seagate BarraCuda SSD is broadly competitive with other TLC SATA drives on The Destroyer, with an average data rate that is clearly slower than the best an MLC drive can deliver but is almost identical to the mainstream Crucial MX500, and significantly higher than the Plextor M8V that pairs Toshiba's 3D TLC with a different controller.
The average and 99th percentile latencies from the Seagate BarraCuda are lower than any of the competing TLC SSDs, and reasonably close to the best we've measured from SATA drives in this capacity class.
The average read and write latencies from the BarraCuda are both among the best we've seen from TLC SATA SSDs, though other current-generation mainstream drives like the Crucial MX500 and Intel 545s aren't significantly behind. The average write latencies in particular vary little among top-tier SATA drives (MLC or TLC).
The 99th percentile read and write latencies show more variation between SATA drives than the averages, and here the Seagate BarraCuda continues to distinguish itself by taking the lead among TLC SATA drives, followed closely by the Intel 545s.
The Seagate BarraCuda's solid performance on The Destroyer comes at the cost of rather high energy usage, almost 40% higher than the Intel 545s that is slightly faster overall. The aging Phison S10 controller is probably the main culprit here, but the Plextor M8V with the same NAND but a Silicon Motion controller is also relatively inefficient on this test.

Looking forward to these being the first SSDs exhibiting the "click of death". Makes no sense I know, low quality humor. I actually do have a Seagate Archive 8TB in my case.Donkey2008 - Thursday, December 13, 2018 - link
If any manufacturer could accomplish this it would definitely be Seagate. They are the Hynix of hard drives - Mostly OEM, not reliable and shockingly still in business. I wouldn't buy anything from that company if my life depended on it.Donkey2008 - Thursday, December 13, 2018 - link
Oh, and I laughed when I first read your comment :-)aylak - Friday, December 7, 2018 - link
I owned several mechanical hard drives from Seagate and all of the failed at some point. I know it doesn't mean that their SSD drives will be as unreliable but it is funny that first thing came to my mind is this as I saw the title.Alim345 - Saturday, December 8, 2018 - link
There was one particularly unreliable series of those hard drives. Also HDD are not absolutely reliable and will inevitably fail after some timeBeaver M. - Wednesday, December 12, 2018 - link
Indeed. Yet Seagate wasnt very good at that either. They had far higher failure rates than WD and even Samsung (which also werent great).But its good to see that this seems to have changed. At least with their bigger drives. They seem to be on par with WD now, but WD isnt as good as it was a few years ago. I guess this HDD cartel made them sloppy.
Thats why I bought a Toshiba and HGST (shortly before they rebranded them as WD).

When it was an independent company, Sandforce never demonstrated the ability to effectively test and debug their products. So the good think about Seagate going with a time-tested Toshiba controller is that it's possible to buy these drives and be confident that they will work correctly. If Seagate drops the price to the point where these drives represent a good value for the money, I would have no problem recommending them.III-V - Sunday, December 9, 2018 - link
Bit hard to read the article title on the front page -- white text on white photo doesn't really work!Billy Tallis - Monday, December 10, 2018 - link
There's supposed to be a partially transparent dark overlay at the bottom of the photo to serve as a background for the title text. Try re-loading the page, and if it still doesn't render, send us a bug report with a screenshot.
