The file preview capabilities of the two platforms are similar. So, tools for previewing your files in the cloud are limited, and neither platform enables you to edit documents or images without downloading them. IDrive and Backblaze are both designed primarily as cloud storage platforms, not cloud-based productivity suites. However, you can pay extra to keep outdated file versions for one year or indefinitely. Even if you discard old versions, files are only truly deleted from IDrive when you empty out the built-in archive folder.īackblaze only keeps old file versions for 30 days. These files do count against your storage limit, so you have control over how many versions to keep and for how long. With IDrive, you can store up to 30 previous versions of a file for an unlimited amount of time. When it comes to file versioning, IDrive is much more robust than Backblaze. For files that you want to keep constantly synced across all your devices, IDrive offers a dedicated sync folder in your file explorer. You also get to set the schedule when these folders are backed up. One thing we like about both the IDrive and Backblaze backup clients is that you get to choose what folders to designate for upload to the cloud. Otherwise, just robotically buying the most expensive, or least expensive, drives is turning a blind eye to the expense side of the ledger.IDrive offers a backup and sync app for desktop and mobile devices (Image credit: iDrive) He said that modeling drive costs and failure rates this way is important when buying thousands of drives a year: “The need for such a model is important in our business if you are interested in optimizing the efficiency of your cloud storage platform.

Model 1 and Model 3 have the same total drive cost ($1,412,500) when the annualized failure rate for Model 1 is 3.83 percent.

Model 1 and Model 2 have the same total drive cost ($1,325,000) when the annualized failure rate for Model 1 is 2.67 percent.

Klein then asked: “How much failure can we tolerate before our original purchase decision is wrong?” Using the values in the table he computes that: The last line in the table shows this comparison. The table lists the total cost of the drives over five years, factoring in the total lifetime drive replacement cost, which is added to the total cost of each drive model.Įven though, with the low-end model, more drives fail and the total drive replacement cost is higher than for the middle and top-end models, the acquisition cost is low enough for the total drive cost to be lowest of the three. There is no drive replacement cost as “all drives are returned for credit or replacement to the manufacturer or their agent.” They share the same replacement labor cost, $300. The three drives are priced as low, medium, and high with AFR values of 1.5, 1, and 0.5 percent respectively.
