What is this TLER feature, you may be asking yourself and why would it be important?
Well, TLER (Time-Limited Error Recovery) feature is particularly important because it prevents the drive from spending too much time trying to fix a faulty sector, which could cause a RAID controller to mistakenly mark the drive as failed and drop it from the array.
Since,each of these drives is a 3.5-inch Large Form Factor (LFF) hard drive with a standard SATA 6 Gb/s interface. This means it can be physically mounted in the 3.5-inch caddy of almost any major server brand, as long as the server model supports LFF SATA drives.
Remember the caddy is specific to the server brand and generation, not the drive. Since the drive is a standard 3.5-inch drive, you would need to buy the appropriate caddy for the specific server you plan to use (e.g., a Dell X7K8W caddy for a Dell R740 server).
