The minimum size for a Time Machine backup drive should be at least twice the size of the Mac primary storage. So, whatвЂ™s the best size for the Time Machine backup drive? We want to keep a balance between capacity and the price, if possible. When the difference in price between 1TB and 2TB may not be too high, when we are moving up in size, doubling the storage comes with more than double price. However, we need to be practical, because extra bytes come with extra price. Ideally, you want as much storage as you can get. The second most important factor is storage capacity. On the market for decades, here is the list (not complete) of companies which If you are not familiar with which manufacturers have been If you get anything from this article, I want to remind you that brands matter when reliability is the most important factor in choosing a backup drive. I think we all know the answer: some reviews on Amazon are fake. So many times, IвЂ™ve seen several thousands of 5-star reviews on no name devices, and at the same time, good devices get a couple of hundreds of reviews, and the average is 3.5. If Amazon is your choice when it comes to purchasing anything online, be aware that not all user reviews are real. There is not a single model that is 100% fail free.Дevices produced by well known established companies have lower rates compared to drives from unknown manufacturers. If the drive fails when you need it, then itвЂ™s not worth even a penny. It doesnвЂ™t matter how fast the disk is, how sleek it looks, or how good the discount was on Amazon. The main factor in selection is reliability. There are certain qualities that I look for when considering hard drives for any backup.

They added: 'After the first scan error, drives are 39 times more likely to fail within 60 days than drives without scan errors.CHECK PRICE How to Choose Hard Drives for Time Machine Brand name 'We find that the group of drives with scan errors are 10 times more likely to fail than the group with no errors,' said the authors.

The report also looked at the impact of scan errors - problems found on the surface of a disc - on hard drive failure. 'This is a surprising result, which could indicate that data centre or server designers have more freedom than previously thought when setting operating temperatures for equipment containing disk drives,' said the authors.

'Only at very high temperatures is there a slight reversal of this trend.'Д«ut hard drives which are three years old and older were more likely to suffer a failure when used in warmer environments. The report said that there was a clear trend showing 'that lower temperatures are associated with higher failure rates'. 'One possible explanation for this behaviour is the survival of the fittest theory,' said the authors, speculating that drives which failed early on in their lifetime had been removed from the overall sample leaving only the older, more robust units. Hard drives less than three years old and used a lot are less likely to fail than similarly aged hard drives that are used infrequently, according to the report. Google employs its own file system to organise the storage of data, using inexpensive commercially available hard drives rather than bespoke systems. The firm then stores that information 'essentially forever'. In the report the authors said Google had developed an infrastructure which collected 'vital information' about all of the firm's systems every few minutes. The report was compiled by Eduardo Pinheiro, Wolf-Dietrich Weber and Luiz Andre Barroso, and was presented to a storage conference in California last week. First, only very young and very old age groups appear to show the expected behaviour.'ДЄ hard disk was described as having 'failed' if it needed to be replaced. 'However our results appear to paint a more complex picture. The authors wrote: 'We expected to notice a very strong and consistent correlation between high utilisation and higher failure rates. It was also thought that hard drives preferred cool temperatures to hotter environments. There is a widely held belief that hard disks which are subject to heavy use are more likely to fail than those used intermittently. 'Our data indicate a much weaker correlation between utilisation levels and failures than previous work has suggested,' the authors noted.ДЄ wide variety of manufacturers and models were included in the report, but a breakdown was not provided. The firm uses 'off-the-shelf' drives to store cached web pages and services. The report examined 100,000 commercial hard drives, ranging from 80GB to 400GB in capacity, used at Google since 2001.

The impact of heavy use and high temperatures on hard disk drive failure may be overstated, says a report by three Google engineers. Hard disks are getting smaller with greater storage
