We&#8217;re done, and Storage Pod 5.0 is here and it is faster, beefier, easier to assemble, easier to maintain, and less expensive than <a href=\"https:\/\/www.backblaze.com\/cloud-storage\/resources\/storage-pod\" target=\"_blank\" rel=\"noopener noreferrer\">Storage Pod 4.5<\/a>. It is also the hardware that enables us to offer our newly announced <a href=\"\/blog\/b2-cloud-storage-provider\/\" target=\"_blank\" rel=\"noopener noreferrer\">Backblaze B2 Cloud Storage<\/a> for just $0.005\/GB\/month. As always, <a href=\"\/blog\/come-and-get-em-storage-pods-that-is\/\">the Storage Pod<\/a> design is open-source and we\u2019ve included the instructions and diagrams you\u2019ll need to build your very own Storage Pod 5.0.<\/p>\n<h2>Building for the Future<\/h2>\n<p>Storage Pods have always been designed and built to provide Backblaze with low-cost data storage. When we decided that we were going to offer <a href=\"https:\/\/www.backblaze.com\/b2\/sign-up.html\">B2 Cloud Storage<\/a> as the lowest cost cloud storage in the world, we doubled down on making our storage infrastructure more durable and more performant without raising the cost of storing data. Step one was designing and deploying the Backblaze <a href=\"\/blog\/vault-cloud-storage-architecture\/\">Vault architecture<\/a> to improve durability. Step two was designing and building Storage Pods that were more performant and lower cost to use in the Vaults. That\u2019s why we built Storage Pod 5.0.<\/p>\n<h2>What\u2019s New in Storage Pod 5.0<\/h2>\n<p>When you look at Storage Pod 5.0, nearly everything, inside and out, looks different than<a href=\"https:\/\/www.backblaze.com\/version-history.html\"> previous versions<\/a>.

This reduces the cost of the power supply component by nearly 50%. There are two power supplies, each with their own wiring harness. We modularized each wiring harness into two assemblies. The first assembly, the pigtail, goes from the power supply to a 20- or 24-pin Molex connector and the second assembly goes from the Molex connector to the individual backplanes. To use an alternate power supply, you replace the pigtail assembly so it has the correct connections for the given power supply.

We discovered that when we stacked multiple 5.0 Storage Pods in a rack, they were too snug. The thicker cover added too much height. To solve the problem, slide and latch covers made of 24 gauge steel were designed, built, and tested\u2014they worked.

Nothing changed, as the drives stayed cool and didn&#8217;t fail at higher rates. In Storage Pod 5.0 we only use three fans which are now thinner (25mm vs. 38mm) and lower in power than before. We also created a &#8220;fan module&#8221; to hold all three fans in one bracket. After removing the covers, it takes just two screws to remove the new fan module. This speeds up assembly and reduces downtime during replacement of a failed fan. It also lowers the overall cost of the chassis.<\/p>\n<p><a href=\"\/blog\/wp-content\/uploads\/2015\/11\/fan-tray.jpg\" target=\"_blank\" rel=\"noopener noreferrer\" data-rel=\"lightbox-gallery-sLyoCmQX\" data-rl_title=\"\" data-rl_caption=\"\" title=\"\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-45141\" src=\"https:\/\/www.backblaze.com\/blog\/wp-content\/uploads\/2015\/11\/fan-tray.jpg\" alt=\"fan tray\" width=\"700\" height=\"350\" srcset=\"https:\/\/backblazeprod.wpenginepowered.com\/wp-content\/uploads\/2015\/11\/fan-tray.jpg 700w, https:\/\/backblazeprod.wpenginepowered.com\/wp-content\/uploads\/2015\/11\/fan-tray-300x150.jpg 300w, https:\/\/backblazeprod.wpenginepowered.com\/wp-content\/uploads\/2015\/11\/fan-tray-560x280.jpg 560w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/a><\/p>\n<p><strong>Rails:<\/strong> Or should we say, tool-less rails.

Call us sentimental fools, but we continue to shell out the big bucks for our special blue-light switch. Oh, we looked at a few others; we even tried a couple out, but in the end we stuck with the one we had. OK, it actually has a lot to do with wiring and what type of power is needed versus what\u2019s available. But let\u2019s just say we like the blue light and leave it at that.<\/p>\n<p>We also did not change the five-port backplanes. The SATA 3 (6 Gbit\/s) backplane speed provides the throughput needed at the right price, so there was no need to change or upgrade this item. If there is a place for improvement, it is the PCIe bus. Our current PCIe x2 SATA cards utilize one PCIe lane for two SATA ports. We are looking at different strategies to remove this last potential bottleneck.<\/p>\n<h2>The Cost<\/h2>\n<p>There are actually three different prices for a Storage Pod. Here are those three costs of an 180TB Storage Pod 5.0 system, including 45 Seagate (4TB) ST4000DM000 drives, for the scenarios noted:<\/p>\n<ol>\n<li><strong>$7,974.44&lt;.\/strong&gt; The cost for Backblaze, given that we purchase 300+ Storage Pods per year.<\/strong><\/li>\n<li><strong>$8,493.11.<\/strong> The cost for you to build one Storage Pod by buying the parts and assembling it yourself.<\/li>\n<li><strong>$10,439.10.<\/strong> The cost to you to purchase one already assembled Storage Pod from a third-party supplier, and then purchase and install the hard drives yourself.<\/li>\n<\/ol>\n<p>These prices do not include packaging, shipping, taxes, VAT, etc.<\/p>\n<p>Below are the Backblaze costs for building the different Storage Pod versions.<\/p>\n<div align=\"center\">\n<table style=\"width: 80%; border-collapse: collapse;\">\n<tbody>\n<tr align=\"center\">\n<th colspan=\"7\"><strong>Storage Pod Version<\/strong><\/th>\n<\/tr>\n<tr>\n<th align=\"left\"><span style=\"line-height: 14px;\">\u00a0<\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>1.0<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>2.0<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>3.0<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>4.0<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>4.5<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>5.0<\/strong><\/span><\/th>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\">Backblaze Cost<\/td>\n<td style=\"text-align: center;\">7,867<\/td>\n<td style=\"text-align: center;\">7,394<\/td>\n<td style=\"text-align: center;\">7,568<\/td>\n<td style=\"text-align: center;\">9,305<\/td>\n<td style=\"text-align: center;\">8,688<\/td>\n<td style=\"text-align: center;\">7,974<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\">Drive Size (TB)<\/td>\n<td style=\"text-align: center;\">1.5<\/td>\n<td style=\"text-align: center;\">3<\/td>\n<td style=\"text-align: center;\">3<\/td>\n<td style=\"text-align: center;\">4<\/td>\n<td style=\"text-align: center;\">4<\/td>\n<td style=\"text-align: center;\">4<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\">Total Storage<\/td>\n<td style=\"text-align: center;\">67<\/td>\n<td style=\"text-align: center;\">135<\/td>\n<td style=\"text-align: center;\">135<\/td>\n<td style=\"text-align: center;\">180<\/td>\n<td style=\"text-align: center;\">180<\/td>\n<td style=\"text-align: center;\">180<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\"><a href=\"\/blog\/hard-drive-cost-per-gigabyte\/\">Cost per GB<\/a><\/td>\n<td style=\"text-align: center;\">0.117<\/td>\n<td style=\"text-align: center;\">0.055<\/td>\n<td style=\"text-align: center;\">0.056<\/td>\n<td style=\"text-align: center;\">0.052<\/td>\n<td style=\"text-align: center;\">0.048<\/td>\n<td style=\"text-align: center;\">0.044<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td colspan=\"7\"><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>As you can see in the table above, Storage Pod 5.0 is less expensive per GB to build and fill with hard drives than all its predecessors. The entire system, fully populated with 180TB worth of hard drives, costs Backblaze just over $0.044 per GB, and that includes assembly costs (labor). In addition, with the price of larger capacity hard drives starting to move down the pricing curve, the cost per GB for these hard drives should continue to decrease and drive down the cost of each Storage Pod we build.<\/p>\n<h3>Why Did the Cost Go Down?<\/h3>\n<p>Before we celebrate the drop in the Storage Pod cost, let&#8217;s take a look at why it decreased. Was it market forces at play driving down the per GB cost of the hard drives? Or did the cost of the Storage Pod chassis and components drop, meaning our design efforts using Agile and Scrum actually made a difference? Here&#8217;s the breakdown of the costs (labor not included) comparing Storage Pod 4.5 with Storage Pod 5.0. Remember, these are Backblaze costs based on our purchasing 300+ Storage Pods per year.<\/p>\n<div align=\"center\">\n<table style=\"width: 90%; border-collapse: collapse;\">\n<tbody>\n<tr>\n<th align=\"left\"><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>Storage Pod 4.5<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>Storage Pod 5.0<\/strong><\/span><\/th>\n<th align=\"center\"><span style=\"line-height: 14px;\"><strong>Change<\/strong><\/span><\/th>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\">Chassis and Components<\/td>\n<td style=\"text-align: center;\">$2,563.31<\/td>\n<td style=\"text-align: center;\">$2,349.44<\/td>\n<td style=\"text-align: center;\">-8.3%<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: left; font-weight: 600;\">Drives (45 Seagate 4TB)<\/td>\n<td style=\"text-align: center;\">$5,850.00<\/td>\n<td style=\"text-align: center;\">$5,175.00<\/td>\n<td style=\"text-align: center;\">-11.5%<\/td>\n<\/tr>\n<tr style=\"border-top: 1px solid #b0b0b0;\">\n<td style=\"text-align: right; font-weight: 600;\">Totals<\/td>\n<td style=\"text-align: center;\">$8,413.31<\/td>\n<td style=\"text-align: center;\">$7,524.44<\/td>\n<td style=\"text-align: center;\">-10.6%%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<div align=\"center\">The verdict: <em>Both elements helped drive down the cost of Storage Pod 5.0.<\/em><\/div>\n<p>Given that Storage Pod 5.0 is faster and beefier than 4.5, and given the expected decrease in assembly and maintenance costs, the time spent designing Storage Pod 5.0 using Agile seems to have been worth the effort.
