![]() ![]() In any case, we cannot say that one type of storage device is more reliable than another - they all can fail and require safety measures to store data reliably.īut judging only by workload and TBW ratings, SSDs are at least as reliable as NAS-oriented WD Red Pro HDDs. ![]() ![]() HDDs and SSDs in data centers are used in tiered storage subsystems and in RAID mode to store data reliably. While they are reliable, they are fragile and sometimes fail, which is why hard drive makers introduced workload ratings to their products several years ago. But modern hard drives use high-precision mechanics and motors that spin at 5,000 – 7,200 RPM. SSD makers have to use very sophisticated controllers supporting these tricky coding and error correction algorithms to improve endurance at the device level.īy contrast, magnetic media (the coating on the platters) can be re-written practically without any limits (at least with no limits worth mentioning). The actual HDD platters are still considerably more reliable than NAND flash media simply because modern 3D TLC NAND is rated for about 10,000 program/erase cycles. Does this mean that SSDs are now more durable than HDDs in terms of the possible amount of data that could be written? Well, yes and no. Needless to say, if we compare endurance ratings of SSDs and HDDs in terms of endurance per terabyte of capacity, SSDs will win again. For example, Western Digital's Ultrastar DC SN840 (opens in new tab) 6.4TB drive is suitable for 35,000TB written over five years. Both of these WD_Black and WD Red SSDs cater to mixed and read-intensive workloads, so we aren't even talking about enterprise-grade SSDs for write-intensive workloads. In contrast, the endurance of Western Digital's own 2TB WD_Black SN850 SSD (opens in new tab) is 1,200TB over five years, whereas a 4TB WD Red SA500 NAS SATA SSD (opens in new tab) is rated for 2,500TB over five years, which is higher than the Red Pro 20TB. Competing IronWolf Pro HDDs from Seagate have a similar workload rating, and the same applies to products from Toshiba. The WD Red Pro comes with a five-year limited warranty, so it is designed to withstand a workload of 1,500TB (including reads and writes). Even community tools like the Help Wiki is built on crowd sourced information! Check it out to see how you can get started as a contributor.ServeTheHome recently compared the latest Western Digital WD Red Pro 20TB (opens in new tab) NAS hard drive's 300TB annual workload (which includes reads and writes) to the endurance ratings for modern SSDs.
