Fast storage is the buzz word in the computer storage industry. We are familiar with HDD (Hard Disk Drive) with all types of computer devices. HDD has a moving read/write head to access data from storage same like a gramophone player and slower to read and write. Unlike HDD, SSD (Solid State Drive) has no moving parts, and it obtains data from storage instantly. SSD can give fast performance than traditional magnetic-based computer storage devices. "A standard SSD can read sequential data at a speed of about 550 megabytes per second (MBps) and write it at 520 MBps" (Paul Rubens). As it is a fast storage SSD consumes only less power and give long battery life for laptop computers. 

Let's check the pricing of SSD. Price of SSD storage is a little bit higher than HDD. Western Digital SATA 1 TB Desktop Internal Hard Disk cost Rs. 3700. Crucial MX500 1 TB Laptop, Desktop Internal Solid State Drive cost Rs. 10647. The price of SSD is dropping down. SSDs for computers are available in 120 GB to 4 GB capacities. Anyway, we can consider small capacity SSD (120 / 240 GB) for desktops and laptops. Visit any online shopping sites to check the pricing of SSD with various capacities.

Majority of Koha installations running on desktop computers with traditional HDD. Libraries can improve the performance of Koha using SSD storage. Koha installation consumes only small storage, 120 /240 GB SSD is enough for libraries with a small collection. The price of 120 GB SSD cost around Rs. 2300, and 240 GB cost only Rs. 3200 only. Koha users with HDD can replace to SSD. Take back of the database and everything. Need to install Koha fresh into SSD after storage upgrade. Libraries going for new Koha installation can specify SSD storage in the purchase order.
