Disclosure: The Ultra II 240GB SSD review unit is supplied by SanDisk

Solid-State drives have come a long way, especially with those who fabricate their own SSD controller and NAND. PCIe and M.2 SSDs are also on a rise ever since the Intel Z170 chipset, but due to the usual lulz that I get to face here, The last SanDisk review is an incredibly small 240GB USB 3.0 storage drive Extreme 500. The SanDisk Ultra II is an older driver, but it is still there in the market and this review should help interested buyers to consider this as an option.

As per specifications, SanDisk Ultra II SSDs promised to run sequential read up to 550MB/s and Sequential write up to 500 MB/s, irrespective of the storage variant. These drives are with three years warranty period. Very recently, SanDisk SSDs namely the Ultra II was a rage during Black Friday online deals, enough that a lot of people purchased it. Even a friend imported two of these for RAID setup along with a mini-ITX motherboard.

Packaging and Specification

The packaging is pretty standard for a standalone drive and it has enough information you’ll need.

The drive’s contents are pretty basic. Though it does come with a riser for the SSD when installed in certain notebooks and info about SanDisk dashboard.

The lower casing is of plastic construction while the upper is metal. Nothing really out of the ordinary, though some manufacturers stick to using a metal casing for both sides. Plastic casing, however, is lighter and cost-effective. In some sense, it helps to trickle down to its users. The thickness of the SSD is 7mm, which is required to be installed in ultrabooks. Considering desktop cases of different form factors now come with more than one SSD cage or tray, a desktop kit is not really required.

Closer Look

The SanDisk Ultra II uses its 1Ynm ABL X3 NAND. This is a 19nm MLC NAND that’s primarily made to provide smaller-size storage chips for mobiles, tablets, solid-state drives for consumers and enterprise.

Sub-components Overview

There’s a total of 4x SanDisk 19nm TLC NAND on each, followed by four-channel Marvell 88SS9190-BJM2 controller. There’s an SK Hynix H6TC2G63FFR DDR3 DRAM. Though I am purely speculating at this moment, let’s not be surprised if SanDisk uses similar NAND on the Extreme 500 at the very least. The PCB is well within Extreme 500’s dimensions.

  1. Thanks for the review, could you give us some ideas about “Better options out there for heavy workloads”? Which drives could you recommend for that? I couldn’t see the options on the review… Thanks!
