Tests have shown that some modern SSDS allow you to record several petabytes of data before failure
The survivability of solid state drives over the years, this segment has not disappeared. He’s probably not as relevant as five to seven years ago, but buyers are still worried how long the drive will last, because of his failure of not just entail the need to buy a new device, but can also deprive the user of important information.
Resource ComputerBase last year decided to test some contemporary models. Testing began on June 23, 2016 and was completed a few days ago. The list of subjects included 200 BX Crucial, OCZ TR150, 750 Samsung Evo, Samsung 850 Pro, SanDisk Extreme Pro and SanDisk Ultra II. For more correct data, each model was involved in two copies.
To begin, we note that all participants exceeded the promised party option TBW (Total Bytes Written) showing how much data you can write to the drive. Of course, the indices of the six models cannot be extrapolated to the entire market, but in General, if talking about well-known manufacturers, buyers can focus on the parameters.
The first was out both the drive Crucial BX 200 with the memory of TLC. They managed to record 187 and 280 TB of data, when the promised 72 TB. That is, the result in the worst case exceeds the promised 2.5 times.
Drives 750 Samsung Evo, the result showed more than 1.2 PB. Model TR150 OCZ and SanDisk Ultra II was between 750 Samsung Evo and Crucial BX 200. Unfortunately, detailed data is available only in the paid report. By the way, only there you can learn about the volumes of the tested SSD.
In second place was the SanDisk Extreme Pro, which managed to write down about 2.2 PB of data. The drives went down due to power problems and not due to the exhaustion of the capacity of memory chips.
Well, the leader was the Samsung 850 Pro with a score of 9.1 PB! And this despite the declared 150 TB. That is, the result exceeded the manufacturer’s promises 60 times.
