  1. Exclusive: World's largest hard drive leaked in product roadmap Seagate confirms Exos X20+ HAMR HDD (Image credit: Seagate) Seagate has already confirmed plans to release its first hard drives featuring heat-assisted magnetic recording (HAMR) technology later this year and recently the first of such drives was listed in the company’s product roadmap, obtained by TechRadar Pro. As it turns out, Seagate’s upcoming HAMR HDDs are listed as Exos 20+, which confirms that the company’s first HAMR drives are set to feature a 20TB capacity. Over time, the company will also release HAMR HDDs with even greater capacities, but has not yet confirmed precisely how large these drive will be. Perhaps Seagate does not want to disclose capacities of its future Exos drives for competitive reasons, but usually capacity points are not considered as top-secret information. Further, customers of Seagate and Western Digital need to have an idea about upcoming capacities so they can plan effectively for the future. (Image credit: Seagate) HAMR Seagate’s upcoming Exos 20+ hard drives are expected to be drop-in compatible with existing 3.5-inch bays, which means that power consumption of the new HDDs will be lower than 12W. The HDDs will feature a 7200RPM spindle speed, so sustained read/write performance of the drives will likely be higher than 261 MB/s, the speed of today’s top-of-the-range Exos hard drives. What remains to be seen is random read and write performance of the Exos 20+ HDDs, as well as their IOPS/TB ratio. In addition to HAMR hard drives, Seagate is also preparing to launch its Mach.2 HDDs with two actuators. Seagate’s multi-actuator technology will double sequential read/write performance and significantly improve IOPS/TB performance of hard drives. At present, select customers of Seagate are testing prototype HAMR drives, but capacities of these test drives are lower than 20TB. Exclusive: World's largest hard drive leaked in product roadmap
  2. Seagate ships 18TB HDDs, but breakthrough hard drives will arrive later this year Seagate’s Exos 18TB HDDs available to select customers, HAMD HDDs on track for 2020 launch (Image credit: Seagate) Seagate Technology has started shipping its hard disk drives featuring a 18TB capacity to select customers, and revealed that HDDs will be more broadly available later this year. But while 18TB drives significantly increase storage capacities of modern datacenters, Seagate has a more important launch set for the next few months, as it also intends to start commercial shipments of its drives based on heat-assisted magnetic recording (HAMR). The importance of HAMR — a technology that has been explored for 66 years now — is fundamental as it is expected to enable hard with capacities of up to 80 TB in the coming years. “We began shipping 18TB drives as part of our system solution in the March quarter, with shipments to select cloud customers and channel partners starting in the June quarter,” said Dave Mosley, CEO of Seagate. “We expect to begin ramping 18-terabyte drives within the calendar year, which aligns well with market readiness.” HAMR incoming As expected, Seagate’s first HAMR-based HDDs will feature a 20TB capacity using heat-assisted conventional magnetic recording without any ‘shingling’ and therefore these drives will offer predictable write performance. “We remain on track to begin shipping our first commercially available HAMR drives in late 2020 on 20TB capacities. HAMR technology will be the industry's path to achieving drive capacities of 30, 40, 50 terabytes and even higher. We plan to offer 20TB HAMR drives to customers on a limited basis and is part of our system solution to collect production and field data.” It is noteworthy that Seagate has been shipping 16TB HAMR drives to select customers for a while and to that end it already has quite some information how these HDDs behave in tightly-packed datacenters. As it turns out, the company wants to gather some more data about performance of the technology.

  3. Seagate unloads the fast flash at CES 2020. Seagate launched two new high-performance external SSDs for gamers on the go, the FireCuda Gaming SSD and BarraCuda Fast SSD. Both boast the latest USB-C interface, but, while their ports are common, their performance capability differs greatly. The fastest of the two, the FireCuda Gaming SSD, is cutting-edge. The company states it is the perfect companion for the recently released FireCuda Gaming Dock. Powered by Seagate’s FireCuda 510, a high-performance NVMe SSD, and coming with a SuperSpeed USB 20Gb/s (USB 3.2 Gen2×2) interface, it can reach top speeds of up to 2 GBps. But, bear in mind that because the FireCuda features an SLC write cache, this high-performance won’t remain so high after you fill the drive with data. Along with strong performance, it’s got style. It features a chisel metal enclosure and RGB lighting, which you can easily manage with Seagate’s Toolkit software. The device can even sync colors with the FireCuda Gaming Dock, too. It will be available in capacities of 500GB, 1TB, and 2TB in March. MSRPs are $189.99 (500GB), $259.99 (1TB), and $499.99 (2TB) and the drives come with a five-year limited warranty. Seagate is also launching a new BarraCuda Fast SSD. It is oriented towards mobile gamers and power users. It is slightly smaller, making it a better choice for those on the run. Like the FireCuda Gaming SSD, the BarraCuda Fast SSD features some lighting effect, but instead of RGB, it is a static green light. It will be available in the same capacities of 500GB, 1TB, and 2TB, too, but offer lower performance at a cheaper price point. Powered by a SATA SSD and USB 3.1 Gen2 Type-C interface, the BarraCuda Fast SSD offers performance figures of up to 540 MBps, putting hard drives to shame. It will be available this February, comes backed by a three-year warranty, and has listed retail MSRPs of $94.99 (500GB), $169.99 (1TB), and $299.99 (2TB). Additionally, these new SSDs are preformatted with exFAT, and they are both macOS and Windows compatible out of the box.

  4. Seagate backs up a truckload of flash, and introduces a gaming dock, too. Seagate is blazing up a firestorm with the release of two new storage products for gamers, a new gaming dock, and a PCIe 4.0 x4 FireCuda SSD. The company is also refreshing a few of the other SSDs in its lineup, too. FireCuda Gaming Dock Seagate’s FireCuda Gaming Dock is a high-end gaming hub that integrates a docking station and external storage into one device. It’s meant to be a perfect fit for laptop gamers who aren’t ready to jump on the desktop gaming PC bandwagon yet. As many laptops are constrained by storage, Seagate is launching the unit with 4TB 7200RPM HDD inside for those growing game libraries. The company also threw in a PCIe 3.0 x4 M.2 expansion slot just in case you’re looking to add some high-speed NVMe storage, too. The dock features one-cord plug-and-play connectivity over a single Thunderbolt 3 input. There are also 10 connections to the docking station to connect your other peripherals. • 1x TB3 port for accessory devices • 1x DisplayPort 1.4 • 4x USB 3.1 Gen 2 ports • 1x USB 3.1 Gen 2 battery charge port • 1x RJ45 Ethernet network port • 1x 3.5mm audio-in / mic port • 1x 3.5mm audio-out port Unfortunately, there is no charging support for laptops, so you will have to use your power brick when you're connected to the dock. But it offers a slick industrial design with LED illumination. It comes to market with an MSRP of $349.99 and a three-year warranty. FireCuda 520 SSD If the gaming dock wasn’t enough to spark your interest, Seagate’s new PCIe 4.0 x4 M.2 NVMe SSD just might. It’s Seagate's top-of-the-line SSD, and a solid choice to add some more speed to your new AMD Ryzen 3000 build. Like a few other PCIe 4.0 SSDs in the market, Seagate’s FireCuda 520 features a Phison E16 SSD controller that has been validated by the company. Paired with Kioxia’s 96L BiCS4 TLC NAND flash, Seagate says this combo enables incredible performance with up to 5,000/4,400 MBps of sequential read/write throughput and up to 760,000/700,000 random read/write IOPS. The drive comes with a black PCB and has an MTBF rating of 1.8M hours. It also comes with a five-year warranty with endurance figures of up to 3,600 TB to match. Available now, Seagate’s FireCuda 520 comes in three capacities: 500GB, 1TB, and 2TB. MSRPs are $124.99 (500GB), $249.99 (1TB), and $429.99 (2TB). FireCuda 510 SSD Refresh While the FireCuda 520 launch steals the spotlight, Seagate’s FireCuda 510 PCIe 3.0 x4 M.2 NVMe SSD gets some love, too. Today, Seagate told us that it is refreshing the FireCuda 510 with new hardware. First, Seagate added in a black PCB to appeal for those concerned about aesthetics. Who likes ugly blue and green PCBs distracting from your blacked-out or red accented gaming build, anyways? Seagate also swapped out the NAND from 64L BiCS3 to the latest Kioxia 96L BiCS4 flash. They have also added in a 500GB capacity point because high-capacity models are a hot seller. Barracuda 510 SSD Refresh Just as the FireCuda is expanding to smaller capacities, the company’s mainstream PCIe 3.0 x4 M.2 NVMe SSD, the BarraCuda 510, is getting a 1TB model. Like the FireCuda, the BarraCuda features a Seagate-validated Phison E12 SSD controller and the latest Kioxia 96L BiCS4 flash, but not the fancy black PCB. The main difference between the BarraCuda 510 and FireCuda 510, other than aesthetics and capacity points, is that the BarraCuda is a single-sided M.2 SSD optimized for flexible compatibility, while FireCuda is a double-sided M.2 solution optimized for enhanced performance and greater endurance. BarraCuda 120 SSD Refresh To conclude the refresh list, we finally have the BarraCuda 120 SSD. Seagate’s BarraCuda 120 is a 2.5 in × 7mm SATA 6Gb/s SSD that replaces the previous BarraCuda SSD. Seagate replaced the internals with new and up-to-date hardware. The company also swapped out the aging S10 SSD controller and replaced it with a Phison S12 SATA controller to ready it for 3D NAND. Seagate will have two sources of NAND for this SSD. Depending on inventory, the BarraCuda 120 will come with either Kioxia 96L BiCS4 TLC or Micron 64L TLC to ensure consistent supply.

    WD or SEAGATE?

    guys i had a question which is better hard drive manufacturer? Seagate or Western Digital? for me Seagate will last long but my favorite was WD for external hard drive best brand was Seagate but for internal?
  6. My last two blog posts were about expected drive lifetimes and drive reliability. These posts were an outgrowth of the careful work that we’ve done at Backblaze to find the most cost-effective disk drives. Running a truly unlimited online backup service for only $5 per month means our cloud storage needs to be very efficient and we need to quickly figure out which drives work. Because Backblaze has a history of openness, many readers expected more details in my previous posts. They asked what drive models work best and which last the longest. Given our experience with over 25,000 drives, they asked which ones are good enough that we would buy them again. In this post, I’ll answer those questions. Drive Population At the end of 2013, we had 27,134 consumer-grade drives spinning in Backblaze Storage Pods. The breakdown by brand looks like this: Hard Drives by Manufacturer Used by Backblaze As you can see, they are mostly Seagate and Hitachi drives, with a good number of Western Digital thrown in. We don’t have enough Toshiba or Samsung drives for good statistical results. Why do we have the drives we have? Basically, we buy the least expensive drives that will work. When a new drive comes on the market that looks like it would work, and the price is good, we test a pod full and see how they perform. The new drives go through initial setup tests, a stress test, and then a couple weeks in production. (A couple of weeks is enough to fill the pod with data.) If things still look good, that drive goes on the buy list. When the price is right, we buy it. We are willing to spend a little bit more on drives that are reliable, because it costs money to replace a drive. We are not willing to spend a lot more, though. Excluded Drives Some drives just don’t work in the Backblaze environment. We have not included them in this study. It wouldn’t be fair to call a drive “bad” if it’s just not suited for the environment it’s put into. We have some of these drives running in storage pods, but are in the process of replacing them because they aren’t reliable enough. When one drive goes bad, it takes a lot of work to get the RAID back on-line if the whole RAID is made up of unreliable drives. It’s just not worth the trouble. The drives that just don’t work in our environment are Western Digital Green 3TB drives and Seagate LP (low power) 2TB drives. Both of these drives start accumulating errors as soon as they are put into production. We think this is related to vibration. The drives do somewhat better in the new low-vibration Backblaze Storage Pod, but still not well enough. These drives are designed to be energy-efficient, and spin down aggressively when not in use. In the Backblaze environment, they spin down frequently, and then spin right back up. We think that this causes a lot of wear on the drive. Failure Rates We measure drive reliability by looking at the annual failure rate, which is the average number of failures you can expect running one drive for a year. A failure is when we have to replace a drive in a pod. This chart has some more details that don’t show up in the pretty chart, including the number of drives of each model that we have, and how old the drives are: Number of Hard Drives by Model at Backblaze The following sections focus on different aspects of these results. 1.5TB Seagate Drives The Backblaze team has been happy with Seagate Barracuda LP 1.5TB drives. We’ve been running them for a long time – their average age is pushing 4 years. Their overall failure rate isn’t great, but it’s not terrible either. The non-LP 7200 RPM drives have been consistently unreliable. Their failure rate is high, especially as they’re getting older. 1.5 TB Seagate Drives Used by Backblaze The Seagate Barracuda Green 1.5TB drive, though, has not been doing well. We got them from Seagate as warranty replacements for the older drives, and these new drives are dropping like flies. Their average age shows 0.8 years, but since these are warranty replacements, we believe that they are refurbished drives that were returned by other customers and erased, so they already had some usage when we got them. Bigger Seagate Drives The bigger Seagate drives have continued the tradition of the 1.5Tb drives: they’re solid workhorses, but there is a constant attrition as they wear out. The good pricing on Seagate drives along with the consistent, but not great, performance is why we have a lot of them. Hitachi Drives If the price were right, we would be buying nothing but Hitachi drives. They have been rock solid, and have had a remarkably low failure rate. Back at the beginning of Backblaze, we bought Western Digital 1.0TB drives, and that was a really good choice. Even after over 4 years of use, the ones we still have are going strong. We wish we had more of the Western Digital Red 3TB drives (WD30EFRX). They’ve also been really good, but they came after we already had a bunch of the Seagate 3TB drives, and when they came out their price was higher. What About Drives That Don’t Fail Completely? Another issue when running a big data center is how much personal attention each drive needs. When a drive has a problem, but doesn’t fail completely, it still creates work. Sometimes automated recovery can fix this, but sometimes a RAID array needs that personal touch to get it running again. Each storage pod runs a number of RAID arrays. Each array stores data reliably by spreading data across many drives. If one drive fails, the data can still be obtained from the others. Sometimes, a drive may “pop out” of a RAID array but still seem good, so after checking that its data is intact and it’s working, it gets put back in the RAID to continue operation. Other times a drive may stop responding completely and look like it’s gone, but it can be reset and continue running. Measuring the time spent in a “trouble” state like this is a measure of how much work a drive creates. Once again, Hitachi wins. Hitachi drives get “four nines” of untroubled operation time, while the other brands just get “two nines”. Untroubled Operation of Drives by Manufacturer used at Backblaze Drive Lifetime by Brand The chart below shows the cumulative survival rate for each brand. Month by month, how many of the drives are still alive? Hitachi does really well. There is an initial die-off of Western Digital drives, and then they are nice and stable. The Seagate drives start strong, but die off at a consistently higher rate, with a burst of deaths near the 20-month mark. Having said that, you’ll notice that even after 3 years, by far most of the drives are still operating. What Drives Is Backblaze Buying Now? We are focusing on 4TB drives for new pods. For these, our current favorite is the Seagate Desktop HDD.15 (ST4000DM000). We’ll have to keep an eye on them, though. Historically, Seagate drives have performed well at first, and then had higher failure rates later. Our other favorite is the Western Digital 3TB Red (WD30EFRX). We still have to buy smaller drives as replacements for older pods where drives fail. The drives we absolutely won’t buy are Western Digital 3TB Green drives and Seagate 2TB LP drives. A year and a half ago, Western Digital acquired the Hitachi disk drive business. Will Hitachi drives continue their excellent performance? Will Western Digital bring some of the Hitachi reliability into their consumer-grade drives? At Backblaze, we will continue to monitor and share the performance of a wide variety of disk drive models. What has your experience been?
