The Dell 055J8H is a 1.92TB SATA solid state drive for servers. It is a mixed use drive, so it handles reads and writes in a steady balance. Dell sources it from Intel, and it matches the Intel D3-S4610 1.92TB.
Intel rates the drive at 3 full drive writes per day. Over its life, that adds up to about 10.5 PB of writes.
Up to 560 MB/s for reads and 510 MB/s for writes. For small 4 KB random work, expect about 97,000 reads and 46,500 writes per second.
Yes. The drive has enhanced power loss data protection.
The drive is a 2.5-inch, 7 mm SATA model on a Dell tray. It fits a hot-swap bay that takes 2.5-inch SATA drives. Match the part number to your server's drive list. Dell also writes it as 55J8H.
SATA drives run at 6Gb/s and cost less to run than many SAS drives. Many server bays take both types.
Three drive writes per day on a 1.92TB drive means about 5.76TB of new data every day for five years. Most mixed workloads write far less than that, so the rating leaves plenty of room.
Read latency is about 103 microseconds and write latency is about 54 microseconds. The drive draws about 3.0 W on average while writing. A mean time between failures of 2,000,000 hours is listed.
Pick it for mixed work, such as small databases, virtual machines, web apps and file servers that both read and write. Skip it if the job is almost all reads, since a read intensive drive can do that for less. Skip it for nonstop heavy writes, where a write intensive SAS drive is the better match.
