How do I check my SSD write limit If you can see how much lifetime data you’ve written on your current SSD, you can estimate its remaining lifespan. Power surges could potentially damage your drive too, so having a surge protector between your computer and the wall outlet is never a bad idea. APC sells a seven-outlet unit for around $60, so you don't need to break the bank to add protection to your home office. If the power goes out, the battery will provide enough power for you to finish your write cycle and properly shut down your computer to avoid corruption. A UPS is like a surge protector with a big battery that you plug your devices into. So, how can you prevent power cuts to your solid-state drive? An uninterruptible power supply (UPS) is the simplest and easiest solution. Researchers published a study in 2013 showing that major data corruption could happen after a power outage, and there have been more than a few other examples of SSD data loss following a power outage since then. ![]() For example, if the power to a drive cuts out during a write cycle, you could lose the data you're writing (at best) or lose the drive altogether (at worst). Power outages can wreak havoc with just about any piece of computer equipment, and SSDs are no exception. Just Download Crystal Disk Mark and install it. While most people who use SSDs daily don't need to worry about this, business users or people who store lots of data for a long time (e.g., photographers, designers) may want to be wary: an SSD that gets too warm when stored without power can have reduced data retention abilities. The easiest way to keep track of the number of bad sectors on an SSD is to run ChkDsk (short for check disk) in Windows. It is possible one of the most popular windows 10 compatible software for checking ssd health. Interestingly, the temperature that an SSD is stored can also affect its data retention. (The winter in Minnesota won't do it any favors either.) Big swings in temperature are hard on all electronics, so minimizing those will help. Leaving an SSD in a storage unit all summer long in Arizona will not be good for the longevity of the drive. That being said, SSDs will struggle with extreme temperatures, especially over extended periods. The acceptable storage temperatures for the Kingston SSD are -40º to 85º C (-40º to 185º F), while the WD Black can handle -40º to 70º C (-40º to 158º F). I feel that some have been incorrectly identified, or maybe I have overestimated the rated P/E cycles.SSDs are more resistant than HDDs when it comes to hot and cold.įor example, the Kingston 240GB A400 SSD has an operating temperature range of 0º to 70º C (32º to 158º F), while the Western Digital Black HDD has a range of 5º to 55º C (41º to 131º F). In short, the SMART attributes don't make complete sense to me. There you'll see the estimated remaining life of the drive. Just type 'cmd' into the search bar and open the application. status of your drives from the Command Prompt. It is not at all surprising (in fact expected) to see values for Data Units Read/Written that is many times the size of the disk when its used as your system disk. Or maybe the life is calculated on the basis of TBW rather than P/E cycles? Simply navigate to Settings > System > Storage > Manage disks and volumes > Properties, where the Drive Health information is located. In Windows, you can manually check the S.M.A.R.T. Host Write Commands (how many write commands were issued to the disk over its lifetime) Note: -A prints vendor specific SMART attributes, so these may vary depending on the brand of SSD. For example, if the DWPD is 1 and the warranty period is five years, then you can rewrite the entire SSD once daily for 5 years before anticipating failure. I feel that some have been incorrectly identified, or maybe I have overestimated the rated P/E cycles. DWPD (Drive Writes Per Day) measures how many times you can rewrite an entire SSD every day throughout its warranty period. Therefore attributes 233 and 244 appear to be inconsistent.Īttribute 241 is reporting that the total amount of data written by the host is 1436 GB (= 0x59C), ie 1.5TB. ![]() If we multiply this value by the full capacity of the drive (256GiB), the total writes to flash would be around 7TB.Īttribute 233 is Lifetime writes to Flash in Gigabytes, which is now 0x505 (= 1285 decimal). This seems to be consistent with attribute 231. Actually it would be somewhere between 10 and 30 since we don't know whether the value has just recently clicked over from 99% or is just about to click over to 97%.Īttribute 244 is the Average Erase Count, and its value is 0x19 (= 25 decimal). If the rated number of P/E cycles is 1000, then this attribute is saying that the SSD has been erased 20 times. 100 - ((average erase count / rated PE)(100))īasically it is counting the average number of Program/Erase cycles for each block.
