However, because file systems write pages of data that are smaller (2K, 4K, 8K, or 16K) than the blocks of data managed by the SSD (from 256 KB to 4 MB, hence 128 to 256 pages per block), [50] over time, an SSD's write performance can degrade as the drive becomes full of pages which are partial or no longer needed by the file system.

The format was standardized as EIA-741 and co-published as SFF-8501 for disk drives, with other SFF-85xx series standards covering related 5.25 inch devices (optical drives, etc.) [33] The Quantum Bigfoot HDD was the last to use it in the late 1990s, with "low-profile" (≈25 mm) and "ultra-low-profile" (≈20 mm) high versions.
The SSD 310, Intel's first mSATA drive was released in December 2010, providing X25-M G2 performance in a much smaller package. [12] [13] March 2011 saw the introduction of two new SSD lines from Intel. The first, the SSD 510, used an SATA 6 Gigabit per second interface to reach speeds of up to 500 MB/s. [14]
The Enterprise and Data Center Standard Form Factor (EDSFF), previously known as the Enterprise and Data Center SSD Form Factor, is a family of solid-state drive (SSD) form factors for use in data center servers.
Some SSDs, including the OCZ RevoDrive 3 x2 PCIe using the SandForce controller, have shown much higher sustained write performance that more closely matches the read speed. [9] For example, a typical operating system has many small files (such as DLLs ≤ 128 kB), so SSD is more suitable for system drive.
The drive had a capacity of 2.03 GB (1.69 GB formatted), was available with FAST SCSI-2 (N/ND models) or WIDE SCSI-2 (W/WD models) interface, and was the first hard drive ever to have a spindle speed of 7200-RPM. Owing to the rotational speed, it was very fast but very expensive at the time. The FAST SCSI-2 interface of the N/ND model drives ...
