External Hard Drive WD vs Seagate

Who makes the most solid hard drives? 

Hard drive

A couple of months back we solicited and addressed one from registering's most established inquiries: How long do hard drives really last? That story missed one basic bit of data, however — who makes the most dependable hard drives? Actually, we can now answer that question as well. 

Much the same as last time, this data originates from Backblaze, an everything you-can-consume online reinforcement organization. Backblaze as of now has around 28,000 hard drives fueled up and always turning, putting away a sum of around 80,000 terabytes (80 petabytes) of client information. As you can envision, it is all that much to Backblaze's greatest advantage to guarantee that it purchases solid hard drives. Each time a drive falls flat, it takes extensive time and push to draw the drive, space in another one, and revamp the RAID exhibit. 

Which hard commute maker is the most dependable? 

Backblaze separates its information in two ways — by maker, and by particular commute. The information is genuinely perplexing, yet we'll attempt to separate it into pieces of simple to-process, significant data.  

As of the end of December 2013, Backblaze had 12,765  Seagate hard drives, 12,956 Hitachi drives, and 2,838 hard drive Western Digital drives. These drives are not all the same age — some are very nearly four years of age, while numerous were introduced in the previous year. The odd numbers are on account of Backblaze fundamentally purchases whatever commute offers the most aggressive dollar-every gigabyte proportion, with unwavering quality being an optional variable. For the majority of the most recent four years, Seagate and Hitachi have offered the best value every gig, with Western Digital Red drives just now turning into a feasible choice for Backblaze.

As should be obvious from the chart above, Hitachi drives are by a wide margin the most solid. Despite the fact that the greater part of Backblaze's Hitachi drives are currently more established than two years, they just have a yearly disappointment rate of around 1%. The "yearly disappointment rate" is the shot of a drive passing on inside a 12-month period. Following three years of being controlled up all day, every day, 96.9% of Hitachi drives are as yet running. 

Western Digital is somewhat more awful, yet great: After three years of operation, 94.8% of Western Digital drives are as yet running. Backblaze records the yearly disappointment rate of the WD drives at around 3% (I don't think the numbers very include, yet I could not be right). 

Seagate drives are not exceptionally dependable whatsoever. As should be obvious in the second diagram beneath, Seagate drives are fine for the first year, yet disappointments rapidly begin developing following year and a half. Before the end of the third year, only 73.5% of Backblaze's Seagate drives are as yet running. This compares to a yearly disappointment rate of 8-9%.

In Backblaze's words: "If the cost were correct, we would be purchasing only Hitachi drives. They have been rock robust, and have had a surprisingly low disappointment rate." 

Which single hard commute is the most solid? (Furthermore which is the minimum?) 

All in all, then, on the off chance that you need a dependable hard commute you ought to strive for a Hitachi or Western Digital. In case you're searching for a particular commute demonstrate that has great life span, the numbers separate interestingly. 

The two best drives, with 0.9% yearly disappointment rate over more than two years, are the Hitachi GST Deskstar 5k3000, and Hitachi Deskstar 7k3000. Get one of these drives and you're just about ensured (97-98%) to endure three years without a dead commute. On the off chance that you need a 4tb commute, the Hitachi Deskstar 5k4000 is your most solid option — it has a somewhat higher disappointment rate, yet underneath WD and Seagate's offerings. 

The extent that poor dependability goes, Seagate has some awful wrongdoers. The 1.5tb Seagate Barracuda 7200 (an old commute now) has a high risk of falling flat following three or four years. Indeed the fresher 3tb Seagate Barracuda has a really high disappointment rate, at 9.8% every year. 

Backblaze likewise notes that a few drives (the Western Digital Green 3tb and Seagate Barracuda LP 2tb) begin delivering slips when they're opened into a stockpiling unit. They think this is because of the a lot of vibration brought about by a great many other hard drives. (They likewise imagine that their forceful twist down setting, which is apparently to spare force, causes a considerable measure of wear to the drive.)

Samsung and Toshiba 

Shockingly, Backblaze doesn't have a measurably noteworthy number of Samsung or Toshiba drives introduced. Indeed along these lines, on the grounds that Samsung's hard commute division was procured via Seagate in 2011, its tricky to say if a more seasoned, preacquisition Samsung drive would be pretty much dependable than a post-securing commute. Toshiba/Fujitsu still have a sensible wedge (~10%) of the piece of the pie, however sadly we'll need to sit tight for an alternate study to perceive how they contrast with Seagate, Western Digital, and Hitachi. 

On the point of acquisitions, you might likewise recall that Western Digital gained Hitachi GST just about two years back. In the event that we look at Hitachi drives from prior and then afterward the obtaining, the yearly disappointment rate appears to continue through to the end (around 1%). Little doubt remains that Western Digital and Hitachi have the dependable hard commute business sewn up — and this is before we've had an opportunity to see what WD/HGST's helium-filled hard commu.
