The Dell 0Y4TH9 is a 1.92TB SAS solid state drive made for Dell Compellent storage arrays. It is a read intensive drive on a 12Gb/s SAS link. It is a 2.5-inch drive and comes with a tray. Seller listings name Samsung as the maker.

Compellent drive notes

Dell sells many drives for its SC Series arrays, and each one has its own part number. Seller listings tag this drive with a CML suffix, as in Y4TH9-CML. That suffix marks the Compellent version of the part. Match the full part number to your array's drive list before you add it.

What read intensive means

Drive makers sort flash drives by how much writing they are built to take. A read intensive drive is built for the lighter end. It suits arrays where reads far outnumber writes, such as file data, reports and backup targets. It usually costs less than a mixed use or write intensive drive of the same size.

Drive count and spares

Each drive holds 1.92TB. Ten drives give 19.2TB of raw space, before any RAID overhead. Plan the pool size first, then count the drives you need, plus a spare.

SAS at 12Gb/s

SAS is the drive link used in most storage arrays. At 12Gb/s it moves data faster than SATA at 6Gb/s. Typical power draw for this drive is about 5 W.

Checklist for your array

• Confirm that your enclosure takes 2.5-inch SAS drives.
• Match 0Y4TH9 to Dell's drive list for your array model.
• Keep a spare drive of the same part number on the shelf.
• Use read intensive drives where reads far outnumber writes.

Who should skip it

Skip it if your array needs write intensive SSDs for its fast tier. Skip it if your array is not in the Dell Compellent family. Check Dell's guide for your array to see which drive types each tier accepts, then match the part number.
