The Seagate BarraCuda (500GB) SSD Review: Getting Back In The Game
by Billy Tallis on December 7, 2018 8:00 AM ESTMixed Random Performance
Our test of mixed random reads and writes covers mixes varying from pure reads to pure writes at 10% increments. Each mix is tested for up to 1 minute or 32GB of data transferred. The test is conducted with a queue depth of 4, and is limited to a 64GB span of the drive. In between each mix, the drive is given idle time of up to one minute so that the overall duty cycle is 50%.
The Seagate BarraCuda fares poorly on the mixed random I/O test, as do the other Phison S10 drives, even the PNY CS2211 with MLC NAND. The Plextor M8V is the next slowest drive with a mainstream controller, so it appears that the poor performance here from the Seagate BarraCuda is at least partly due to the NAND and is not just due to the Phison S10 controller.
Power Efficiency in MB/s/W | Average Power in W |
Most mainstream SATA drives in this capacity class average around 1.5-1.6W during this test, so the efficiency rankings largely mirror the performance rankings. That leaves the BarraCuda again near the bottom of the chart.
The fastest drives on this test are the ones that avoid performance drops when writes are added to the mix and instead steadily gain performance as the test progresses. The Seagate BarraCuda doesn't pull that off, with performance that drops when writes are first added to the mix and doesn't recover until near the end of the test when the workload is almost entirely writes.
Mixed Sequential Performance
Our test of mixed sequential reads and writes differs from the mixed random I/O test by performing 128kB sequential accesses rather than 4kB accesses at random locations, and the sequential test is conducted at queue depth 1. The range of mixes tested is the same, and the timing and limits on data transfers are also the same as above.
The Seagate BarraCuda had great sequential read performance and competitive sequential write performance, but it doesn't handle mixed sequential workloads all that well. As with the mixed random I/O test, the Phison S10 drives are all clustered at the bottom of the chart along with the DRAMless SSDs, while the other mainstream TLC SSDs offer at least 26% higher overall performance—and that comes from the Plextor M8V that uses the same Toshiba 3D TLC as the BarraCuda.
Power Efficiency in MB/s/W | Average Power in W |
The BarraCuda is again one of the most power-hungry drives, surpassed only by the Phison S10 SSDs that use planar NAND, so it earns one of the worst efficiency scores. The slow DRAMless SSDs at least manage to use far less power during this test, so they end up with pretty good efficiency scores.
The BarraCuda starts off with great sequential read performance, but as soon as writes are added to the mix, throughput plummets. It stays slow through most of the test, recovering only slightly toward the end to deliver just over 300MB/s on pure writes. That final write speed isn't too bad, but most mainstream drives spend the read-heavy half of the test performing well above that level, instead of below 250MB/s.

The caddy would adapt an m.2 to a full 2.5" SATA socket, so you would have an m.2 in a chassis adapting it to 2.5" & classic SATA.That being said, I can't see that doing anything but increasing costs, though having one primary line to manufacture m.2 and the little bit of work needed to adapt an m.2 SATA drive to 2.5", it *could* see some benefit to the manufacturer.

Huh? M.2 SATA doesn't overheat, that's M.2 NVME/PCIe (which is a bit more difficult to adapt to 2.5" SATA, so I don't care as much). 2.5" SATA drives already have tiny PCBs. They are already bottlenecked by the protocol. With them being M.2 in a 2.5" caddy, they can serve double purpose. I just bought an M.2 drive and a caddy for my Fujitsu T904 laptop, which still has only a 2.5" slot. But I know when that laptop is gone, I'm not gonna need a 2.5" drive. That M.2 drive can be converted into all kinds of useful devices, small desktops, laptops, USB thumb drive. It'd cost them a couple dozens of cents more to manufacture, would it'd be soo much more useful. :D Eventually, more people will use M.2 SATA than 2.5". At least those who buy standalone drives.CheapSushi - Saturday, December 8, 2018 - link
Dragonstongue I don't think you really know what the OP is talking about, just how tiny the PCB seems to be on newer 2.5" SSDs, thus just being a whole lot of waste of space anyway and/or you don't realize adapters already exist and/or don't realize M.2 is just a formfactor and can be NVMe/PCIe or AHCI/SATA. There's always someone who confidently posts a "neg" at a suggestion without even knowing hardware much in the first place.dgingeri - Friday, December 7, 2018 - link
When I was a systems admin for a server software test lab, we received a set (108) of 3TB Seagate Constellation ES.2 SAS drives for a new prototype appliance that would eventually become the DXi6900 series. I was pretty excited to see the new hardware come in, so I got things set up within a day.The test team wasn't ready to test for another week. In that week, we had 12 of those drives go bad. By two months into the project, every single Seagate drive had gone bad. (These are their enterprise level drives, which are supposed to have better reliability.) We ended up requesting a different brand drive from NetApp (the maker of the storage portion of the DXi6900) because of these problems. We replaced them with HGST 4TB drives, and didn't have a single one fail up to the point when I left over two years later.
In the years leading up to that, I had bought several Seagate drives, including 4 1TB drives, 2 2TB drives, and one 3TB drive, and had the drive fail within warranty in EVERY SINGLE CASE. That was specifically why I quit buying them, and the 3TB drive is the last Seagate drive I am ever going to buy intentionally.
This just might be a decent crive, and if Seagate were to put a concerted effort into improving their reliability, they might be something I'd consider. However, as things stand, Seagate and Toshiba are on my NEVER BUY list, along side Biostar, ECS, and Gigabyte.

What does this have to do with SSDs at all? Seriously? This is just some overreaching rant saying that one specific type of product means that ALL their products are a problem. Especially about spinning rust several years old; even BackBlaze doesn't use those. Have you even bothered to look into reliability statistics/information on even consumer TLC drives? It's so odd to see people who claim to be in tech but are so antiquated in their knowledge.gglaw - Sunday, December 9, 2018 - link
Quite a humorous post from someone with a supposed heavy tech/admin background but so short-sighted on the big picture. He lists a bad experience from a completely unrelated product line likely not even sharing manufacturing or R&D ties in any way making him ban products from some of the largest tech companies in the world with for the most part tremendous track records. Even if it is in "principle" for how the company leaders model their QC, all the executives making these decisions at the time of the archaic hard drive problems are likely working with other companies by now (pretty good chance for one of his "new" favorite companies). Similar to the comments on some of Samsung's early SSD fiascos banning all Samsung products "for life." And of course shortly after their fiascos, they quickly became essentially the world's benchmark for performance and reliability in this same product line lol.Donkey2008 - Thursday, December 13, 2018 - link
108 enterprise-class hard drives failed in 2 months?[Insert Doubt meme]

thanks for sharing I really need this for my office.PeachNCream - Friday, December 7, 2018 - link
I think I'd probably opt for a Crucial MX500 over a Seagate SSD. Seagate's reputation and my experiences with their mechanical drives make me reluctant about giving them yet another chance.Fujikoma - Friday, December 21, 2018 - link
I feel the same way about Quantum SCSI drives. Not that Seagate rates much higher...
