01 Dec Hard Drives Present Greater Privacy Risk Than SSDs
In a recent study, data recovery company Kroll Ontrack established that solid state drives (SSD) are less of a privacy risk than hard drives.
The firm tested a total of 64 drives on eBay from several countries: 27 SSDs and 37 HDDs, and found that over half of the HDD drives retained data previously written on them, while only a third of the SSDs did.
Researchers from the firm said that this did not mean that SSDs are immune to risks. However, these kinds of drives did allow for more successful wipes due to several features such as FTL (Flash Translation Layer function), Trim, Garbage Collection and always-on encryption.
